How to make different types of glue with your own hands: the best recipes. Joiner's glue - how to make your own hands
To prepare the glue, some of its amount is placed in a container, to which a thin stream, with constant stirring, adds water, in the ratio of one to two (more should be liquid). It turns out pretty thick mass. It is very important to responsibly approach the process of mixing - the quality of the resulting product directly depends on it.
This event usually takes up to half an hour.
With the help of a mixer with a nozzle, this time can be reduced. The resulting glue perfectly connects parts of wood, leather, is widely used for shoe repair. But the cooked mass should be used within two to three hours, then it will harden and lose its adhesive ability.
The composition of the turbo - liquid glue from old linoleum
Linoleum glue In addition to the above, there are many different methods of preparing high-quality glue for glass, blocks and for PVC.
This composition, prepared at home, can be successfully used for pasting walls and ceiling surfaces. It is enough to choose from a variety of recipes optimally suitable.
A very simple and affordable way is to use old, used linoleum and acetone. The process is very simple. Linoleum must be crushed (cut with a knife or scissors) into small fragments that need to be placed in an airtight container.
Then add acetone in an amount twice the amount of the first ingredient.
The dishes with the contents tightly closed, leave in a dark place for about half a day (12 hours). Usually this time is enough to dissolve the pieces of the floor covering completely. The resulting tool can securely connect products made of porcelain, metal, leather, wood, ceramics and other materials.
In the process of performing many finishing works, glue is a necessary component. With it, glue wallpaper, tile, it is added to the cement mortar. To save on the purchase of glue, we suggest that you read the instructions on how to make glue with your own hands.
Functional features and chemical composition of the adhesive
Glue is a multicomponent composition, which is based on compounds of organic or inorganic substances that easily glue together materials of different origin, and in particular:
- wooden,
- leather,
- tissue,
- paper,
- glass,
- metal,
- plastic,
- ceramic,
- rubber products.
The bonding process represents the formation of a strong bonding bond between the glue in the two sides of the material to be glued.
The chemical composition of the adhesive contains materials of artificial or synthetic, organic or inorganic origin. For example, the basis of a fairly popular silicone glue includes compounds of elemental organics. In order for the consistency of the glue to become liquid and easily applied to the surface, it contains additives in the form of water and organic liquids.
Most sealants based on organic resins are water and are environmentally safe.
Organic solvents are hydrocarbon substances of aromatic or chlorinated type. Such solvents are quite affordable, easily evaporate, non-toxic. The most common are gasoline, acetone, or a substance of elite alcohol.
For the glue to become elastic, plasticizers are required. They act as dibutyl phthalate, dioctyl phthalate, triphenyl phosphate. To reduce the shrinkage of the adhesive, increase its strength and at the same time reduce the cost of using fillers. The use of kaolin, quartz sand, sawdust and other components is recommended as a filler.
If the adhesive is based on thermoactive resins, special hardeners of catalytic type are required, which are sold separately from the adhesive. They are added to the glue immediately before use. Solutions of acids, amines or bases are used as hardeners. When the hardener begins to react with adhesives, polymers with a mesh structure are formed, which are accompanied by a sharp increase in adhesive bonding before high or low temperatures.
The difference between catalysts and hardeners is that they are not capable of entering into such reactions and do not accelerate the process of hardening of the adhesive. Salt, peroxide, and acid are used as catalysts. The main requirement for the use of a catalyst is a strict dosage. If the amount of catalyst is increased, the glue will practically not harden and the adhesive compound will remain fragile.
Adhesives based on thermoactive resins are characterized by the introduction of catalysts, inhibitors or moderators, to adjust the degree of hardening, to accelerate, slow down or stop the process of interaction between accelerators and the main adhesive element.
To increase the viability of glue based on organic compounds, it is recommended to add antiseptics to them. Catalysts are required to be added to polymer glue, they help to increase their durability.
Main types of glue
In accordance with the method of drying, the adhesives are divided into:
- adhesives, which are characterized by drying,
- non-drying type adhesives
- polymeric compounds.
The first option, in turn, is divided into:
- pVA glue,
- silicate based glue,
- glue for carpentry,
- starch based glue.
1. Consider the variety of glue from the most popular PVA glue, which is an emulsion of polyvinyl ether and water, in a small amount of plasticizers and additives. The smell is almost not pronounced, is used for bonding various substances.
There are these types of PVA glue:
- household or wallpaper designation - glues paper products, is used to decorate the walls with wallpaper, looks like a white homogeneous mass, has a white or beige color, is able to defrost and freeze six times;
- office type - glues paper products, photographic paper, cardboard, looks like a viscous liquid, color - white with a yellow tint, unstable before water and frost;
- universal purpose - used for gluing wooden, paper, cardboard, leather, glass substances, is part of the putty, primer, concrete solution, has the appearance of a white slightly yellowish viscous mass, characterized by the presence of six frost-resistance cycles;
- pVA super glue glues wooden, paper, glass, porcelain, leather, fabric, linoleum, tile products, frost-resistant;
- pVA dispersion - appears as an aqueous solution of polymers, which is stabilized using a protective colloidome, such as polyvinyl alcohol, has a high adhesive ability, there are two types of dispersion: plasticized and non-plasticized.
Scope of use of PVA glue:
- as an additive in construction solutions;
- in industrial establishments of textile, shoe, leather, printing origin;
- in the manufacturing process of such products as: cigarettes, paints, technical fabric, household chemicals;
- in the process of gluing paper, cardboard, wooden parts.
Characteristic of PVA glue:
- high level of frost resistance;
- high adhesive abilities;
- environmental safety, non-toxicity, fire safety;
- amenable to most organic solvents;
- if the glue is applied thinly, it is almost imperceptible after drying;
- no shrinkage.
2. Silicate glue is also called liquid glass, this material is actively used both in everyday life and in industry, for bonding any parts.
Scope of use:
- fabrication of sputtering for electrodes, which are used in the welding machine;
- in the engineering industry with a delicate connection of parts;
- in the pulp or paper industry;
- in ferrous metallurgy and chemical industry;
- it is an integral component of most detergents.
Features:
- fire safety,
- water resistance
- frost resistance
- resistance to acidic solutions.
3. Adhesive joinery used when gluing wood parts. There are three types:
- tiled,
- chip,
- granulated.
In relation to the composition emit glue:
- merzdovogo,
- bone type.
The first is stronger than bone, characterized by a greenish tinge. Bone glue has an orange-brown color. Joiner's glue provides for its cooking. Chip glue is boiled immediately, and the tile is pre-crushed.
4. Starch-based glue is called paste, its production is quite simple, it is necessary to mix the starch with water and heat it to a state of glue. The best quality is glue based on starch from corn, and the worst - potato starch. It is recommended to apply it during the day.
Materials that will be required in the process of manufacturing PVA glue:
- half a liter of purified water
- 2.5 grams of photographic gelatin,
- 2 grams of glycerin,
- 50 grams of wheat flour,
- 10 mg of ethanol.
Pre-soak gelatin in water for a day, it should swell. Gelatin should be exactly photographic.
When gelatin is ready to use, it is required to build a water bath. To do this, take a pot of water and put it on the stove. Find a bowl suitable for the diameter of the pan, and place it on the surface so that it does not come into contact with boiling water.
Put a mixture of water, flour and gelatin in a bowl and cook until it becomes thick as sour cream. At the same time it is required to stir it constantly. Remove mass from heat and add alcohol and glycerin to it. Be sure to stir the mixture so that it becomes homogeneous. When the glue has cooled, it is ready for use.
Before using it, the surface should be well cleaned from dirt and dust. If there are pores on it, prewash them. Stir the glue before applying it to the surface. Then, using a brush or roller, apply glue, and glue the two parts together.
This glue is used for a maximum of six months, at a temperature of at least +10 degrees.
How to make glue from flour yourself
Materials for work:
- wheat or rye flour - 3 tablespoons,
- purified water - 500 ml.
Glue from flour will perfectly cope with gluing paper products or wallpapers. Its production is a fairly quick process that takes no more than half an hour. Therefore, in a situation, for example, when the glue for wallpaper ends, and the store is far away - recommendations on how to make glue with your own hands would be an excellent option.
Instructions for making flour flour paste:
- Put the water on the fire and wait for it to boil;
- separately dilute the flour in a small amount of water;
- pour the flour into boiling water and stir the liquid constantly;
- wait for it to boil and remove the glue from the stove;
- wait for the glue to cool completely;
- now it is ready to use.
Ready-made flour glue looks like thick kissel. As you can see, answering the question how to make glue quickly - making this glue is the best option.
How to make starch glue
The proportions of starch glue are the same as flour flour glue:
- half a liter of water
- 3 tbsp corn starch.
Cooking glue is better in enamel or galvanized dishes. Put a container of water on the fire, wait for it to boil. Separately dissolve the starch and pour it into the liquid. Wait until the glue boils and remove it from the fire.
The main advantage of starch glue is that it is more transparent and leaves no traces. It is recommended to use this glue all without residue, because after a while it loses its abilities. To improve the quality of the starch glue, it is recommended to add 50-100 grams of PVA glue.
If you add carpenter's glue to such glue, it will perfectly cope with the priming of the walls before glueing the wallpaper.
How to make glue using acetone and old linoleum
This method allows you to prepare a universal adhesive material that has a high level of bonding.
To make glue at home using this method, first of all, you need to prepare materials.
Linoleum should be cut into pieces the size of 3x3 cm. Then put it in a container that has the ability to close tightly. Take acetone, its amount should exceed the amount of linoleum twice. Pour acetone in a container with linoleum and place in a place protected from direct sunlight for twelve hours.
If, during this time, the entire linoleum had time to dissolve - use the glue for its intended purpose, otherwise, wait until the linoleum is completely dissolved.
Sphere of use - bonding:
- wooden,
- porcelain,
- metal,
- leather parts.
How to make paper glue
In the case of enthusiasm for origami, quilling or applications for gluing wood parts is ideal this recipe glue. It is based on the use of dextrin, which is also easy to prepare at home.
This requires:
- take a few spoons of starch
- put it in heat-resistant dishes,
- gradually heat in the oven,
- bring the temperature up to 150 degrees
- leave for 90 minutes.
To prepare the glue, you must have:
- three tablespoons of dextrin,
- five tablespoons of water
- one tablespoon of glycerin.
The first step is mixing dextrin with water. The mixture is heated until the dextrin is completely dissolved, while it requires constant stirring. At the end of cooking, glycerin is added. After cooling, the glue is ready for use.
How to make glue titanium
For the preparation of such glue will require the presence of a chemical copolymers of vinyl acetate. It is very difficult to get it, so it is rather difficult to prepare such glue at home.
Consider the advantages and features of titanium glue of industrial origin:
- seemingly clear liquid
- frost resistant
- waterproof,
- heat resistant
- used in the process of gluing ceiling tiles,
- convenient to use.
Making wood glue do-it-yourself
The process of making wood glue is simple and allows you to make glue that can easily glue together any wooden parts. But at the same time, this glue has its drawbacks:
- fast shelf life
- the presence of a disgusting, pungent smell.
Therefore, in the process of cooking, a special mass is produced, which has a greater shelf life. This mass is hard and cut into pieces, which are boiled for further use in the form of glue.
Consider the four most popular ways of boiling wood glue:
1. Take the standard joinery glue. Cut it and leave in water. Wait until it clears. When the mixture is soft, place it in a piece of cloth. So called the tank, which produces the process of melting. Take the tin can and pour the liquid there. Place it in a water bath, stir constantly until glue becomes liquid. For 360 grams of glue, take 475 grams of vodka and put them together. Then add 100 grams of powdered alum. This adhesive has water repellent properties and is characterized by a high level of strength.
2. Dilute the same amount of glue and purified water in the metal container. When the mixture thickens, put it in a mortar and grind it. Pour the mixture into the plate and wait until it is completely thickened. This mass, after cooling, is cut into pieces and used in portions. For 350 grams of glue, you should take 360 grams of water and 180 grams of vodka. Bring all ingredients to a boil and use the glue after cooling.
3. Prepare a water bath. Take half a pound of glue and half a spoonful of vinegar half a liter of water. Boil until the glue dissolves, then add half a liter of vodka.
4. For 250 grams of glue, take 250 grams of water, bring to thicken. At the end of cooking add 250 grams of glycerin. Wait for the water to evaporate. Put the glue in the form and use as needed. To use this glue you need to dilute it with water, in the ratio of one to one.
Video how to make glue:
Any repair, whether in an apartment or a house, will not do without glue. Today, the choice of adhesive mixtures in the store is very, very large. But, their quality, sometimes, leaves much to be desired. Many builders make homemade glue at home right from improvised means. However, we note that in each case the composition of the adhesive may be different, because it may be suitable for different materials, for example, one for paper and the other for wood.
In this article, we will look at various home-made adhesive mixtures that can be easily prepared in simple home conditions, while not spending a lot of money on its preparation. So let's go!
The recipe of paste on the traditional recipe from flour
Such glue is used quite often in a variety of situations. Most often, its preparation is resorted to.when urgently needed, for example, when the glue from the store ends, during the wallpaper update. Therefore, in order not to run to the store for a new pack (which apparently will only be used by 1/3), it is easier to make your own glue, which will not be any worse. In addition to all this glue is not toxic, and quite safe for use at home. The main component is flour, which certainly is in every home. The relationship of glue is the following - 1 liter of glue is enough for 2, 3 rolls of wallpaper.
Prepare the following components:
Capacity in which glue will mix;
6 tablespoons of flour per liter of water;
Water, according to the amount of flour (1 liter per 6 tablespoons).
Prepare the glue as follows:
1. Heat the water to a boil;
2. In a separate container, stir the flour with cold water until a mixture is formed, like liquid sour cream (and always without lumps);
3. Now, pour a thin stream of boiling water into this mixture, while constantly stirring it with a spoon;
4. After mixing, boil the mixture again and let it cool.
The finished consistency should resemble thick kissel. Similarly, you can make this glue with the use of starch instead of flour, and it will not be a bit different from the flour. In some cases, this glue can show itself even more efficiently than the glue from the store. If you are afraid to put such glue on the wallpaper, test it on small pieces of wallpaper, sticking them together. In general, this glue can be used with any wall surface, stick paper with cardboard and other types of paper. In a word, experiment and see everything with your own eyes.
Homemade PVA glue
The second, equally popular and effective is the home glue PVA. If you think that the factory makes glue on some special technology, you are mistaken, because the exact same glue can be made at home. Agree, this type of glue is one of the most common. It is used as inclerical sphere, and in construction, that is, in fact it can be called universal glue. Well, it's time to move on to how to make it all the same. This will require:
1. Distilled water in a volume of 1 l;
2. Photographic gelatin (can be bought in any store of goods for cameras) in the amount of 5 grams;
3. Pharmacy glycerin (4 grams are enough);
4. Wheat flour, about 100-150 grams;
5. Ethyl alcohol in a volume of 20 ml (can be purchased at any pharmacy).
Conventionally, the manufacture can be divided into two stages:
This is a preliminary preparation, during which gelatin must be soaked in a glass of water;
And the cooking process itself.
So, a day after the swelling of gelatin, you can begin to manufacture PVA.
Помест Place distilled water in a water bath, in some container. Next, add the gelatin into it, and stir in the flour mixed in a little water (again, without lumps);
∙ Blend the mixed consistency, but do not boil. Pay attention to how the mixture will be guta and white, like sour cream. Stir it so that the glue is as a result uniform, without lumps.
∙ It remains to add only glycerin and ethyl alcohol. Stir constantly and stir the mixture again so that it is as thick as possible. Stirring time should be about 10 minutes, so do not think that two stirring with a spoon will be enough. It is possible to use glue only after its complete cooling.
How to make a carpenter's glue yourself?
This glue is ideal for wood. Also, it effectively glues paper and cardboard, other materials from cellulose, and in some cases even plastic. However, with this glue you need to highlight a couple of drawbacks:
Firstly, it is not stored for too long in liquid and perishable form;
And secondly, it has just a disgusting and sharp smell, which can only be reconciled.
Partially, this problem disappears if it is pre-boiled and made gelatinous mass. Then, its duration increases, and, if necessary, you can cut a piece of the desired size, heat it over a low fire, and exploit it. There are several recipes for making this glue. The most elementary and accessible to you, we describe below.
Method one. Take ordinary wood glue. Crush it and soak in water until it swells. So, he will soften, and will become like a jelly. In the same condition, place it in a container for melting, called glue. The easiest way such a container can be made from ordinary cans (condensed milk or canned pineapples). Ship the gelatinous mass into such a jar, and put it in a water bath (there must be a very weak fire). Stir the mass, heated with a wooden spoon, or a stick (for example, from sushi). You need to constantly stir, because in the case of burning, the mass will acquire a yellowish color, while losing its adhesive quality. After mass transfer to the liquid state, dilute it with vodka with the following ratio: 720 grams of glue need 950 grams of vodka. Then, for every 100 grams of glue, add 12 g of powdered alum. The resulting homemade carpenter's glue will have a high degree of adhesion and have excellent water repellency characteristics.
The second way.In the same glue, mix the wood glue and water with a ratio of 1 to 1. After the mixture begins to boil, it will thicken slightly, and at this stage it must be poured into a ceramic mortar and rubbed with a pestle until a gelatinous mass is formed. After, lay the glue on a plate, cool, and cut into the necessary pieces. If necessary, mix the glue with vodka in a different ratio - 720g (glue) / 360 g (vodka). Bring the mixture to a boil, then cool anduse.
The third way. Boil a mixture of one liter of water, a kilogram of wood glue, and one liter of 9 percent table vinegar in a water bath. After stirring this consistency, gradually add a liter of vodka to it.
The fourth method. Dilute the wood glue with water in a one-to-one ratio. Heat it in a water bath until the mixture thickens completely. After, add one part glycerol (equal parts of the glue that was originally taken). Put on a small fire and wait until the water evaporates completely. It remains only to lay out the mold and dry the glue. Before using it, mix with water in an amount of 1 to 1.
Homemade glue for foam plastic
Recently, the need for such glue has become acutely acute. This is due to the fact that the cases of wall insulation, sound insulation, in which the use of foam plastic, and other materials like it are necessary, have become more frequent. You can use the glue from the store, but, as a rule, it is afraid of solvents, like acetone. Therefore, you can use the wood glue listed above.
Otherwise, you can make glue, especially for polystyrene, from homemade curd. This will require mixing in equal proportions slaked lime with cottage cheese, stirring, to obtain a homogeneous mass. Try to use this glue immediately after mixing, as it hardens pretty quickly.
Casein-based glue for wood and leather
For gluing wooden or leather products, casein glue will be very effective. This type of homemade glue is also suitable for other materials, for example for gluing puzzles. But, in order to make such glue, you need to get casein itself, so the whole process of glue preparation must be divided into two stages.
The first stage will be to isolate casein from the curd. For this, cottage cheese must be fat free. To get such a cottage cheese, you can soak it in soda solution, and you need to dilute 1-2 tablespoons of soda per liter of water (about 15-20 minutes). After that, it must be thoroughly rinsed with running water, pressed and dried to a hardness. Now, it remains to prepare a powder from it, which will be dry casein.
In the second stage, you need to prepare the glue itself. To make it, you need to pour casein into a flat bowl, pouring a thin stream of water into it. Do not forget to stir the mixture. The ratio will be as follows: for one part of casein, you need to take two parts of water. Need to get a thick mass. Now, the most crucial part of the preparation comes, it is mixing this mass. People the better and better you mix the mixture, the better it will turn out glue. In general, this procedure will take at least 30 minutes, although with a mixer, this can be done faster. As a result, such glue will perfectly glue together wooden fragments, as well as leather, for example, shoes. You need to use this glue as quickly as possible, within 3 hours after production.
Clay for needlework
Needlework involved in many housewives. Quite often they make fabric flowers, which require special fabric glue for their products. This glue can also be made by yourself at home. There are some simple ways that we now consider.
Method number 1
To do this, you need 3 tablespoons of flour and a glass of water. Dilute the flour with a small amount of water, heat the rest of the water, and pour the flour mixed with water into it in a thin stream.
Method number 2
In the second method, we need a tablespoon of flour, also a tablespoon of starch, 1 tbsp. l sugar and a glass of water. Stir all ingredients and bring to a boil, make sure that no lumps form.
Method number 3
You will need a bag of gelatin, two tablespoons of flour, a tablespoon of sugar, and a glass of water. Soak gelatin in 1/3 cup of water at night, and in the morning in the rest of the water, knead the gelatin and the other components. Bring to a boil, and then store the glue only in the refrigerator.
Dextrin based adhesive
For classes with paper, various types of application, it is not always possible to use PVA glue. For example, dextrin-based glue, which is easy to make at home, is ideal. In order to get dextrin, you can use starch. Take the pot, put the starch in it and put it in the oven on a small fire. Gradually increase the temperature of the oven to 160 ° C, and maintain it for about an hour and a half. So, starch will be split, and turn into dextrin.
For the glue you will need 3 tablespoons of dextrin, 5 tablespoons of water, and a spoon of glycerin. Stir dextrin with water, heat the mixture to completely dissolve the dextrin, and then add glycerin. Stir, and after cooling get ready glue.
Glue based on acetone and linoleum
To make homemade glue at home, you can read a lot of recipes, and one of the cheapest is such glue. So, for its preparation you need to take the old linoleum, cut it into small pieces, and impose on the bottom of the pot. Pour it with acetone in the ratio of 1 to 2 parts (1 part linoleum, 2 parts acetone). Then, tightly close the container, and leave for 12 hours (preferably in a dark place). After this time, the glue will be ready. It can glue metal, porcelain, wood or leather.
Universal moisture resistant glue
Pretty simple recipe for a homemade all-purpose adhesive that is moisture resistant. To do this, it is enough to take the wood glue, soak it in water until it is full of swelling. After that, bring to a gelatinous state, adding linseed oil to the container.
Well, as you can see, there are a lot of ways to make homemade glue at home. In addition, each adhesive is suitable for use with one type of material or another. Plus, this is not all recipes for homemade adhesives, because there are really a lot of them.
Polyurethane foam. Help in choosing. Secrets of use
It often happens that during the repair process there is not enough adhesive substance or it is impossible to buy adhesive with the required characteristics in the store. In such situations, you can make the PVA glue yourself, that is, in ordinary home conditions. And in order to make high-quality PVA glue, you need such a foundation, which is available in the kitchen of each hostess.
A modern consumer can purchase several variants of the adhesive base:
- PVA clerical. Glue has a non-waterproof base, it is not allowed to apply it outside the house.
- PVA household glue, which is most often used for wallpapering. This type of adhesive base has a high frost resistance, retains its properties at temperatures up to minus 25 degrees.
- Product brand "M", superfrost. They are allowed to glue the surface at a temperature of minus 35 degrees.
Any type of adhesive provides many advantages:
- resistance to chemical reactions;
- quick setting process;
- no peculiar smell;
- non-toxic base.
The only drawback - a small resistance. However, due to the additional components that manufacturers add to the base, the coefficient of water resistance of the PVA glue has significantly increased.
Self-preparation of the adhesive base
As mentioned earlier, if you do not have the right amount of adhesive on hand, it can be quite simple to do it yourself, at home. To make high-quality PVA glue, you should prepare the following ingredients:
- distilled water (1-1.2 liters);
- gelatin of a photographic type (approximately 5-6 g);
- regular pharmacy glycerin (4-5 g);
- wheat flour (100-120 g);
- ethyl alcohol (20-25 ml).
Any ingredient other than photographic gelatin is quite simple to buy by visiting a nearby store or pharmacy. And the desired type of gelatin should be purchased in advance in a specialty store.
In order to make high-quality PVA glue at home, you need to adhere to the recommendations of specialists, which you can read on the website at a convenient time. The step-by-step instruction for preparing the adhesive base at home will be approximately as follows:
- pre-purchased gelatin must be soaked in ordinary water for approximately one day;
- after the allotted time, it is necessary to dissolve the gelatin base in a water bath;
- to the dissolved component are added all the ingredients that make up the basis of the PVA glue, except for regular glycerin and ethyl alcohol;
- all ingredients are boiled until the mass becomes thick sour cream, and the mixture must be constantly stirred so that the components do not stick to the bottom of the container;
- having obtained the desired consistency, the mass is removed from the water bath, cooled slightly, alcohol and glycerin are added to the substance. All ingredients are thoroughly mixed again, eliminating any lumps that may appear when adding additional components.
At this stage, the PVA glue will be ready; it is possible to use the adhesive substance in ordinary household conditions after the mass has cooled completely. It is difficult to refute the obvious fact, which indicates that it is up to anyone who is willing to make high-quality PVA glue from simple ingredients available to everyone.
Advice on the use of adhesive
To use the base for bonding, it is important not only to make high-quality glue at home, but also to properly prepare the surface to be treated. Experts recommend before sticking to do the following:
- carefully remove any type of dirt and dust from the surface;
- if the surface provides a porous base, it must be treated with soil;
- existing old paint must be removed, the surface should be degreased with a special compound;
- before applying, the adhesive should be thoroughly stirred in a container, a small amount of glue should be applied to the desired element;
- all elements that need to be glued should be firmly pressed to each other or put a special load on them.
Self-made PVA glue can be stored for six months. If the substance is not fully used, the residue should be stored at a temperature of 10-15 degrees with a plus sign. If the adhesive will be stored at a “minus” temperature, it can be used for one month. If in the manufacture of polyvinyl acetate have difficulties, you can always go to the site and view the training video. The lesson will be taught by experienced professionals who have not once made a mass for gluing on their own. The information obtained will help with the ease to make high-quality PVA glue in household conditions for everyone without exception.
How to make a real PVA glue yourself?
PVA is a glue widely used in various fields and, without exaggeration, being one of the most popular.
And although it is possible to purchase this product without problems, independent production is also not difficult, which will help out in a situation where something needs to be glued together without delay, and funds were not at hand.
Is it possible to make white glue at home?
Polyvinyl acetate, better known as PVA glue, is produced commercially on special equipment. A polyvinyl acetate dispersion and a filler are mixed in the mixer.
There are various types of this glue (stationery, wallpaper, universal, etc.) and, accordingly, the recipes for making. It is difficult to precisely observe the recipe of PVA at home, but it is not at all difficult to make an analogue that will practically not be inferior in its properties and characteristics.
How can you make PVA glue with your own hands?
There are many recipes for self-cooking glue. We offer one of the most easily sold and available recipes, almost all of the ingredients of which are sold at the pharmacy (except for photographic gelatin, which you need to look for in a specialized store, as well as flour - if you don’t find it at home, you will definitely find it in the nearest grocery store).
So, for the preparation of PVA you need to take:
- 1-1.2 liters of distilled water;
- 20-25 ml of ethanol;
- 4-5 g of glycerin;
- 5-6 g of photographic gelatin;
- 100-120 g of flour.
Gelatin is soaked for a day in normal warm water from a tap according to the instructions, and then dissolved in a steam bath. Flour and distilled water are added and the mixture is kept on the fire until it becomes thick sour cream. While boiling the mixture should be constantly stirring.
When the necessary consistency is reached, the mixture is removed from the heat and cooled slightly. After that, add alcohol and glycerin and stir everything thoroughly so that there are no lumps. If the formation of lumps still could not be prevented (they may appear at the stage of boiling), then you can skip the glue through a sieve.
When the mass is completely cooled, it can be used for gluing paper, wood and other parts for which PVA is commonly used.
Store homemade product can be no more than six months. The ideal storage temperature is + 10-15 degrees.
Nothing bad will happen if the glue stays at room temperature, but when the minus is on the thermometer, the “functionality” of the product decreases dramatically. It will be usable for no more than one month.
YouTube video about the production of glue
In this video you can visually see how smoothly PVA is done at home. A very simple recipe that makes it easy to make glue even for those who are trying home glue production for the first time.
PVA glue manufacturers in Russia
In Russia, many companies produce PVA glue and dispersions. For most of them, this product is only part of the range. These enterprises specialize mainly in the production of paint and varnish products. In addition, there are firms that produce only PVA products, such as, for example, Polymer Export, Rikol and others. These are large manufacturers engaged exclusively in the production of PVA glue and vinyl acetate-based dispersions.
Choosing a product, give preference to reliable manufacturers, especially if you are going to glue dimensional or expensive items.
PVA glue is used in a wide variety of fields, ranging from gluing paper to various types of industry. This product is widely used in repair work (wallpapering, priming, adding to facing solutions, gluing wood elements, fiberboard, etc.)
This adhesive is used in the printing and packaging industry for gluing paper products. It is also widely used in the woodworking and furniture industry, since PVA does not change the color of wood and allows it to preserve its properties.
In the textile industry, they are “strengthened” by carpets and connecting fabrics. It is also used in the manufacture of glass and paint and varnish products, household chemicals, footwear, etc.
Do the glue with your own hands or better to buy?
The prices for PVA glue vary depending on the type of glue, the manufacturer, the weight of the product, etc. For example, 1 kg of universal PVA glue costs, on average, from 40 to 60 rubles; a five to ten kilogram capacity will cost a little less.
In general, this product has a very democratic price, and if any difficult or demanding work is assumed, then it is better to buy industrial-made glue. But if you already have experience in self-manufacturing of PVA, or you can’t get it, but something needs to be glued together urgently, then you can do it without any problems on your own.
What can replace the PVA glue?
The problem with the replacement of PVA most often occurs in those who live in foreign countries, since this product is sometimes quite difficult to find there. If it suddenly became necessary to find a replacement, then you need to focus on the material of the surfaces that are to be connected. For wooden parts, you can buy a special glue for wood, for wallpapering - “wallpaper”, etc. Paper or cardboard at home is glued together with ordinary paste (made from flour and / or potato starch. So you can easily find a substitute for PVA , the only negative that such products are often more expensive than this universal, inexpensive and popular glue.
How to make PVA glue at home
Preparing the PVA glue on your own, without leaving your home - this is the topic of today's article.
About PVA glue, not exaggerating, we can say that it one of the best and most popular bonding materials. This glue is used for gluing paper, wallpaper, and some other surfaces.
Just want to note that to prepare such glue yourself not a difficult task.
If there is a situation in which you urgently need something to glue together while there is no time or opportunity to go to the store, then you should not get upset, you can cook the PVA yourself. If you follow all the rules and advice, then the prepared glue will turn out no worse than the purchased one, and you will be able to save money.
Polyvinyl Acetate Information
What is polyvinyl acetate? This is the well-known PVA glue. If we talk about the production of glue in industrial scale then make it with special equipment. For its manufacture it is necessary to mix the polyvinyl acetate dispersion and filler. All this is mixed in a mortar mixer.
Household Glue Recipe
You can prepare the glue in several ways, but this is the most simple and common. Besides all necessary ingredientsApart from photographic gelatin, it is easy to buy at every pharmacy. The truth in this recipe is still need flour, in the pharmacy, of course, not to buy it, but any grocery store, as they say in help.
What are the ingredients needed for the manufacture of PVA glue?
- Distilled water. Such water will need approximately a liter and a half.
- Ethyl alcohol, it needs about 25 ml.
- a teaspoon of glycerin. This is about 5 grams.
- as much photographic gelatin.
- And, of course, flour. It will take about 100-110 grams.
- First you need to soak the gelatin in warm ordinary water for a day.
- Then you need it dissolve with steam bath.
- Next to the gelatin must add water and flour.
- The resulting mixture should be kept on fire until a consistency resembling thick sour cream.
- While the mixture is on fire, its should interfere without interruption. After obtaining the necessary consistency, the mixture should be removed from the heat and let it cool slightly.
- Then you need to add glycerin and alcohol, mix the resulting mixture so that there are no lumps.
After the mixture has completely cooled, it can be used to glue the same materials for which PVA is usually used.
You can store self-made glue not more than six months.
Where can PVA glue be used?
Application area This product is wide enough. With it, you can glue wallpaper, wood elements, fiberboard.
Printing, packaging, woodworking, furniture industry, they all successfully use glue for white glue.
The textile industry also uses PVA glue to strengthen carpets and fabric joints. Still its application extends to glass production, paint and varnish products. Household chemicals also can not do without the participation of this wonderful tool.
Well, if you need to glue something simple and to go to the store is not possible, then practice in the manufacture of glue worth it. Thus, the GVA will work, and the practice will appear.
A number of finishing works require the use of glue. With it, you can lay tile and glue wallpaper. Moreover, the composition is sometimes added even to the ingredients of the cement slurry. In order to save on the purchase of factory mix, you can familiarize yourself with the algorithm of work on how to make glue at home.
Main types of glue
If the adhesives are classified according to the drying method, they are subdivided into compositions, which differ in that they are polymerized. Other types of adhesives are non-drying, while still others are polymeric compounds. The first can be divided into compositions based on silicates, starch, as well as PVA glue and a mixture of joinery purposes.
Varieties of glue
The most popular today is PVA glue in the form of an emulsion of water and polyvinyl acetate. Plasticizers and other components are added to the ingredients in the process. The smell of the mixture is almost not expressed, and it is used for bonding different materials. PVA glue can be divided into:
- clerical;
- glue for household use;
- universal composition;
- super glue;
- pVA dispersion.
As for domestic composition, it is intended for gluing paper products, it can also be used as a glue for wallpaper. This mixture has white or beige shades that can be frozen and thawed 6 times. With stationery glue everything is clear, but the composition of the universal purpose allows you to combine not only paper and cardboard, but also wood, glass and leather products. Superglue is a composition that is frost resistant. As for the dispersion, this is an aqueous solution of polymers, stabilized by a protective colloid.
PVA glue manufacturing
If you also were among those who thought about the issue of how to make PVA glue, then you should read the instructions. It involves the preparation of the following materials:
- water;
- photographic gelatin;
- wheat flour;
- glycerol;
- ethyl alcohol.
Water will need half a liter. As for gelatin, it is necessary in the amount of 2.5 g. Glycerin must be prepared in the amount of 2 grams, and wheat flour will need 50 g. Ethyl alcohol goes into the mixture in a volume of up to 10 mg. Wallpaper glue is prepared on the basis of gelatin, which is pre-soaked in water and left for a day, during which time it should swell. Gelatin must be photographic. Once it is ready for use, you need to prepare a water bath.
To do this, take a pot of water and set it on the stove. Next you need to find a bowl that will go into the pan. The first is installed in the second so that the bowl does not come into contact with boiling water. In a bowl is placed a mixture of gelatin, flour and water. This composition should be boiled, but in the end it should get thick, and the consistency should resemble sour cream. The composition will need to be constantly stirring, and after the mass is removed from the heat, and then glycerin and alcohol are added to it. This method is available to everyone, because the ingredients can be found at home.
If you are thinking about how to make PVA glue, you should know that the mixture should be stirred to make it homogeneous. As soon as the glue has cooled, it can be considered ready for use. However, before this surface is cleaned from dust and dirt. If it has a high porosity, then it must be primed. Glue before applying is stirred again, and then distributed with a brush or roller. Details at the final stage are connected to each other. Cooked glue can be used for 6 months at a temperature not lower than +10 ° C.
Making glue from flour
If you are faced with the question of what makes the glue, then the answer to this question may be flour. For the work should be prepared and purified water in a volume of 500 ml. Flour must be rye or wheat, and it is taken in the amount of 3 tablespoons. This paper glue is great. He also copes with gluing wallpaper.
Preparation will be quite simple and will take no more than half an hour. The composition is also suitable for those cases when in the process of wallpapering you suddenly ended the corresponding composition. Shops are not always close, with the manufacture of glue made from flour being an excellent option.
To do this, put the water on the fire until boiling. Separately, the flour is diluted in a small amount, and then poured into boiling water. The resulting composition should be constantly stirred until you wait for it to boil. Next, the adhesive is removed from the stove and left to cool. On this we can assume that it is ready for use. The finished mixture should look like thick jelly. Some people think that such paper glue is the best option, because it is easy to use and requires a minimum amount of ingredients.
Starch use
When making starch-based glue, prepare half a liter of water and 3 tablespoons of cornstarch. As a container, it is better to use galvanized or enameled ware, which is placed on the fire with water until it boils. Starch should be dissolved separately, and then, as in the case of flour, pour into the liquid.
When the glue boils, it can be removed from the fire. The main advantage of this composition is that it turns out to be more transparent and leaves no traces. It should be used without a trace, because in time he will lose his ability. In order to improve the quality of the glue, it is recommended to add about 100 g of PVA glue to it. But if you add a wood glue, the mixture will cope with the priming of the surfaces before gluing the wallpaper.
Using old linoleum and acetone
Homemade glue can be made in such a way as to obtain a universal composition that will provide a sufficiently high degree of adhesion. To create a mixture it is necessary to prepare materials. Linoleum is cut into pieces, the size of which will be 3 x 3 cm. They are placed in a container that will be able to hermetically close. The amount of acetone used should be 2 times the volume of linoleum.
The ingredients are interconnected and left in a container that must be protected from direct sunlight for 12 hours. If during this time linoleum dissolved, then the glue can be used for its intended purpose. Otherwise, it is left for some time. Now you know how to make glue at home. The composition based on linoleum and acetone is excellent for the following materials:
- metal;
- porcelain;
- wood;
- leather.
Making paper glue
If you are thinking about how to make glue at home, you can consider the technology of making the composition for paper. If you like origami or often make applications, this glue recipe is the best for you. It is also good because it can be used for gluing wooden blanks.
It is based on dextrin, which can be prepared at home. To do this, take a few spoons of starch, put them in heat-resistant dishes and begin to heat in the oven. When the temperature reaches 150 ° C, the composition is left for 90 minutes. For the mix, prepare 3 tablespoons of dextrin, one spoon of glycerin and 5 tablespoons of water. In the first stage, water and dextrin are mixed. The mixture is heated until the dextrin dissolves. The composition is constantly mixed. At the final stage, glycerin is added. After cooling, the glue can be considered ready to use.
Manufacturing glue "Titan"
Before you make glue at home, you should decide how you will use it. For example, for the composition of "Titan" will need a chemical - copolymer of vinyl acetate. The problem may be that it is very difficult to get it, so home cooking is not always possible.
Such industrial glue has a transparent consistency and quality of frost resistance. In addition, it perfectly tolerates exposure to temperature and water. You can use it for ceiling tiles, and in the application of this mixture is very convenient.
Making wood glue
Carpentry glue is quite common, you can do it with your own hands too. The process is not complicated, but in the end you will receive a composition that is suitable for gluing wooden parts. However, he has his drawbacks. They are expressed in a short shelf life and a strong smell.
In the process of cooking it is best to perform a mass that can be used for some more time. It will turn out solid and should be cut into pieces before use, which are boiled for further use. For wood glue, you need to take a standard glue for carpentry purposes and cut it, leaving it in water. It should swell, while the mass becomes soft. Next, take a can and pour the liquid there.
The container is placed in a water bath, and the mixture is constantly stirred until the glue becomes liquid. For 360 g of dry formulation, 475 g of vodka should be taken. The components are connected, and then alum powder is added in a volume of 100 g. This adhesive is characterized by excellent strength and high water repellency.
Alternative options for the manufacture of wood glue
If you have a question about how to make glue, the recipe must be considered. As for the carpentry composition, it can be performed on one of the currently known technologies. The first involves the dilution of solid glue and purified water, which are placed in a metal container. They are taken in the same quantity. As soon as the mixture becomes thick, it should be ground in a mortar.
The composition is poured into a plate, and then left until thickening. The mass is cut into individual pieces and used in portions. 350 g of glue will need 360 g of water and vodka in a volume of 180 g. Ingredients are brought to a boil, and glue should be used after it has cooled.
Another method of making glue involves the use of a water bath. At 0.5 liters of water should take 0.5 kg of glue and half a spoonful of vinegar. The composition is boiled until the glue dissolves, then vodka is added in a volume of 0.5 l. Another method of preparing wood glue involves the use of 250 g of glue and the same amount and water. The mixture is brought to thickness, and at the end of cooking you need to add the same amount of glycerin. The water should evaporate, after which the glue unfolds in shape and is used if necessary. Before starting work with the composition should be diluted with water, using a ratio of 1 to 1.
Hot glue making
If you are thinking about how to make hot glue, you should follow the instructions below. It involves the use of 100 g of wood glue and linseed oil in the amount of 35 g. The glue is placed in a glass and cooked over low heat until it becomes liquid. Linseed oil is added to it, and after the mixture is well stirred. Glue is heated before use and perfectly connects wooden surfaces. It can also be used when laying tiles. The mixture is not afraid of hot and cold water.
Features of the manufacture of silicate glue
Some craftsmen wonder how to make silicate glue. At home, this may seem quite problematic. The composition is almost identical to the other mixture of glass - potassium or sodium silicate. Glue can be obtained by combining these compounds with another substance called quartz sand. The temperature at the combination of ingredients should be constant. Sometimes builders perform silicate glue on their own. In this case, use soda. It is melted with sand.
Making glue for laying tiles
If you decide to use tiles to finish the surfaces of one of the rooms of your house, then you need to prepare glue for it. When deciding how to make office glue, you need to take the following ingredients:
- pVA glue;
- water;
- sand;
- cement.
Sand is a filler, its fraction should not be large, the maximum diameter of the elements does not exceed 2 mm. Sand and cement are taken in a ratio of 3 to 1. Tile glue hardens quite quickly, so you need to prepare it immediately before laying the finish. The solution can be used for another 3 hours.
For work on the implementation of the adhesive should be mixed sand and cement. Water is added to the mixture, and before that - PVA glue. If the lining is carried out in a room with high humidity, for example, in a bathroom, the volume of glue can be increased.
Conclusion
Glue may be needed when working on gluing ceramic tiles or wallpaper. Such compositions are abundantly represented on the shelves of hardware stores. But if you want to save, then this mixture can be prepared independently. This solves the question of when the glue has suddenly ended and helps to save money.
