Homemade glue. First, let's repeat the general rules for gluing objects. How to make slime from PVA glue

At the time of repair, there is often a need to use adhesives. With their help you can hang wallpaper and lay out tiles. Glue often becomes one of the main components of the cement composition.

To save your finances by purchasing factory-produced mixtures, you can learn how to make glue at home yourself. We invite you to familiarize yourself with the algorithms for producing a wide variety of mixtures.

Recipe for the most powerful all-purpose solvent and foam adhesive

This adhesive composition is used when the house does not have the required consistency or it runs out at the most necessary moment. The substance is suitable for sudden cracks in the roof. Some people prefer to use such an adhesive composition to fasten objects in the interior or to install a cornice on the ceiling.

Solvent and foam glue can be called the most reliable, so using it, you don’t have to be afraid that the fastened parts will begin to fall off over time.

The adhesive gained popularity due to its reliable fastening of materials such as gas-filled polystyrene, baseboards and furniture elements.

Foam plastic

Foam glue recipe

In order to create the required adhesive consistency, it is enough to perform a number of simple steps:

Pour the solvent into the container. Acetone or solvent No. 646, 647 is suitable. The volume depends on the required amount of glue after creation.
Pour foam into the solvent and keep the material in it until a viscous substance begins to form.

The resulting glue is used to fasten different planes. When the consistency hardens, it reliably holds the treated surfaces for a long time.

You can use a brush to apply the material. This is an ideal option if you need to repair your roof. When the material hardens, it resembles glass.

We looked at the first method, which described how to make glue at home from polystyrene foam and solvent.
To create a bonding composition, you can simply apply crushed foam to the desired location and pour a solvent over it. During the reaction, the material begins to melt, expand and fill all the cracks. Thanks to this, high-quality sealing occurs.

As an example, we can consider the process of sealing cracks on the roof (slate). The composition can be applied and reliably fasten the joints of roofing felt. Please note that if it has a liquid consistency, it will be unusable.

Features of the composition

As in any other process, when working with chemistry, you need to adhere to specific rules. Mixing work should be carried out away from sources of fire. The resulting mixture not only ignites quickly, but also burns for a long time.

Please note that it is best to cook on fresh air, this will not cause harm to health, since mixing in the room can lead to poisoning by chemical fumes.

In addition, we must not forget about this. That the mixed consistency can be used only after a day, and with increasing layer thickness, the hardening time increases.

A similar adhesive composition is used if the necessary glue is not available or it runs out at the most inopportune moment.

Dissolving the foam

To ensure that the resulting consistency dries faster, it is recommended to choose solvents that contain acetone. If the preparation was done correctly, the result can withstand almost any temperature change. For this reason, this glue is used on the roof and in cracks on the house.

Which foam is suitable

We looked at the question of how to make glue at home from polystyrene foam. Now you need to familiarize yourself with exactly what components can be used to create.

Polystyrene foam is a material made from foam masses. It is very often used to insulate living spaces. Depending on the production process, polystyrene foam is divided into 3 categories:

No pressing required. In the final version, this material looks like balls that are interlocked. If you rub several elements of this foam against each other, it will begin to crumble and the balls will separate. The option is used to obtain the glue in question. It can easily be dissolved in acetone and turned into a mass of the required consistency.
Using pressing. The material has an increased strength coefficient in contrast to the previous option under consideration.
Extrusion. This is a foam plastic with a homogeneous structure, since elevated temperatures are used during its manufacturing process.

In addition to the options listed, you can also use granulated foam. However, before using it, you need to check its solubility. It would be appropriate to say that this version of foam is considered the most convenient in creating glue.

Thus, with a solvent and foam at your disposal, you can get an adhesive that is reliable and can last for a long time.

Recipe for making wallpaper glue

If you plan to hang wallpaper, but don’t want to waste extra money, we suggest you read the instructions from the website on how to make glue at home. As a basis you will need to take:

flour;
water.

The number of components used will be selected based on the volume of work to be done. Make the calculation based on the ratio of three tablespoons of flour and 500 milligrams of water.

The creation process itself is very simple, and everything will take no more than thirty minutes.

This glue will ideal option, if during the process of wallpapering, the required consistency has run out, and there are no hardware stores nearby.

How to organize the creation process:

put the water on the switched on stove and wait until it starts to boil;
in a separate plate or pan, dilute flour with half a mug with a small amount of (preferably purified) liquid;
the composition is carefully added to the already obtained boiling water and stirred thoroughly;
Bring to a boil again and remove from heat.

Leave the composition to cool. When it has cooled completely, use it for its intended purpose.

The mixture looks like jelly. Some people believe that this particular glue is ideal for renovating rooms with wallpaper. It is easy to prepare, does not require rare elements, and most importantly does not contain harmful chemical components.

Recipe for making wood glue

Glue for carpentry work is one of the most common and most frequently used consistencies. You can also do it yourself.

The process is elementary, and if you approach this matter thoroughly, you will get a composition that can connect wood products. Of course, this glue has its own negative qualities– this is a sharp and unpleasant aroma, as well as the period of use of the prepared composition.

How can you prepare wood glue?

Option 1

This cooking option is intended for long-term storage ready glue. As a result of cooking, you get hard glue, which, if necessary, can be cut into pieces and used.

You will need:

take wood glue, grind it and put it in a bowl of water;
wait until the mass swells and becomes soft;
pour water with dissolved glue into a glass bottle and set it to heat over steam;
Stir the consistency regularly.

You can remove the glue from the stove when the water from the container has almost evaporated. Pour the finished glue into the molds and leave until it cools completely.

Another version of wood glue is made using one of the most well-known technologies today. Is there a dry composition? Use it for cooking purposes. You will need an adhesive mass of 360 grams of the composition and 500 grams of vodka.
All components are combined and 100 grams of alum are added to them. We are waiting for everything to boil. Use the mixture after it has cooled completely. The glue will be durable and water-repellent.

Option 2

Let's consider another option for making a carpentry-type cool consistency. It is designed for use during steam cooking.

You will need (based on 500 ml of liquid):

500 grams of glue;
half a tablespoon of vinegar;
500 grams of vodka.

The glue is poured into the liquid and acetic acid is added to the composition. The consistency cooks until you notice that the adhesive ingredient has dissolved. After this, vodka is poured into the composition and mixed.

This cooking method can be improved, but for this you need to take 250 grams adhesive composition, the same amount of water. Bring everything to a boil, and at the end of cooking, add glycerin.
The finished mixture is poured into molds and used as needed. Please note that before use, the composition must be diluted with water in equal proportions.

Recipe for silicate glue for paper

If there is a need for silicate glue for paper, we recommend that you familiarize yourself with the following creation technology, which will be given below.

This glue is indispensable if a person likes to practice the technique of folding paper figures. It is silicate glue that is suitable for this task.
Not many people know that this adhesive consistency can be used on wooden objects, which has additional benefits.

The composition of silicate glue contains main component– dextrin. You can even prepare it at home. What you will need for the work process:

Place two small spoons of starch in a container made of heat-resistant material and heat in the oven;
when the temperature reaches 150 degrees, the composition is placed in the oven. Approximate cooking time is one and a half hours. The component is ready.

We are preparing glue. Prepare: glycerol, dextrin, water.

The first thing you need to do is combine water with dextrin. We heat the mixture and wait until the component melts in the water. At the final stage, add glycerol to the previously obtained mixture. When the consistency becomes room temperature, you can use prepared glue.

How to make PVA glue at home

If you are one of those who often encounter the need to use PVA composition, check out detailed description How to make high-quality PVA glue at home.

Before you make your own pva glue at home, prepare:

water;
gelatin;
flour (preferably wheat);
glycerol;
ethyl alcohol.

As for the amount of each ingredient, you will need at least 500 ml of water. For this amount of liquid, take a few grams of gelatin and the same amount of glycerin, and 50 grams of flour is enough. As for ethyl alcohol, take 10 milligrams.

To understand how to properly make glue at home, we recommend that you read the detailed instructions:

First put the gelatin in the liquid and leave until the next day. During this period it will swell.
As soon as the gelatin is prepared, you need to organize a steam bath. Place the container with liquid on the stove. Choose a bowl that can grip the edges of the pot of water. Please note that the container should not touch the boiling water.
Gently add gelatin to a separate plate with water and stir until completely dissolved and add flour. Place it all on low heat and stir thoroughly while cooking.
When the mixture resembles thick sour cream, remove from heat.
Add glycerin to the consistency you have obtained and pour in alcohol. When ready-made composition Once it cools down, it can be used for its intended purpose.

Now you have learned how to properly make pva glue at home. This cooking method is elementary; many ingredients are available at home or purchased within walking distance.

Flour glue recipe (for fabrics)

To glue all kinds of fabric-based ones together, a lot of glue is required. If the additives are selected in the correct quantities, you can prepare and stock up on several liters of high-quality glue. The glue will not deteriorate and will not lose its qualities even if it is placed at room temperature.

In order for the fabric to stick together firmly, you will need to make a grain-type paste. For this purpose, you need to break wheat or oat grains in a coffee grinder powered by electricity. Of course, you can use a manual unit, but the grinding quality will not be high.

The resulting mass does not need to be sifted; it is filled with water and boiled. When everything swells, you will need to pass the consistency through cheesecloth; there is no need to rub the mixture through it. Alcohol and PVA glue are poured into the liquid; we described above how to make glue correctly at home. The finished consistency can be used according to its intended purpose.

If you plan to work with heavy fabrics, then instead of wheat and PVA, you can brew rye grains in a steam bath and add wood glue with alum.

The need for glue can arise at any time, even at the most inopportune moment. You can’t talk about saving money if you have to buy a whole package of industrial glue to fix a small defect in your home. It is more economical to prepare it yourself and in the quantity needed. All this allows us to solve the problem of the sudden end of the adhesive composition.

How to make super glue at home? — This question is often asked by home craftsmen who do not want to spend money on professional solutions or who simply incorrectly calculated the required volume for the work, but need to increase it. In order not to give up and run headlong to the store, you can make homemade glue, which will be better in quality than store-bought glue. In this article we offer you several tried-and-tested recipes. various types glue.

Traditional recipe for making wallpaper paste from flour

The glue, which is made from flour, is prepared in the proportion of 1 liter per 2-3 rolls of wallpaper.

In order to prepare it, you will need:

any container whose volume is sufficient for the required amount of glue;
wheat flour - 6 tbsp. l.;
water - 1 l.

Cooking procedure:

Heat the water until hot.
In a separate container, dilute in a small amount of cool water required quantity flour until a homogeneous mixture is formed that does not contain lumps.
Pour the mixture in a thin stream into boiled water while stirring constantly.
Bring to a boil again and leave to cool.

Important! In its finished form, such glue must have the consistency of a fairly thick jelly. Similarly, you can make glue from starch, which in its quality will be no different from flour glue.

In terms of gluing efficiency, both starch and flour pastes, in special cases, even surpass ready-made ones industrial adhesives. The wallpaper that is glued with them adheres perfectly to any surface. With it you can glue all types of paper.

Preparing PVA glue from improvised materials

The most common adhesive, which is widely used not only during execution repair work at home, but also in large-scale buildings, PVA glue is used. This is rightfully super glue, which is very easy to make with your own hands, and the range of applications of which is so universal that you can solve any problems with such a solution:

It is considered an excellent wallpaper glue.
It can also be successfully used during the preparation of mortars for tiling, as a primer for surfaces, before proceeding with the final finishing.
It is also used for gluing various elements of furniture and interior items.

Important! We can say with complete confidence that polyvinyl acetate is a kind of lifesaver for any owner who can independently prepare PVA glue.

In order to prepare PVA glue, you will need:

1 liter of distilled water;
5 g gelatin, which is intended for photographs;
4-5 g pharmaceutical glycerin;
wheat flour 100 g;
20 ml of ethyl alcohol, which can be purchased at a pharmacy.

The preparation of glue occurs in 2 stages:

Once the gelatin has already swollen in water, you can start preparing your homemade PVA glue:

Place the container along with distilled water in a water bath.
Add prepared gelatin to it, stirring with a small amount of ordinary water so that there are no lumps.
Bring the entire mixture to a boil, but do not boil under any circumstances. It should definitely become like thick sour cream.
To ensure that the mixture is homogeneous, stir it constantly.
Add glycerin and alcohol. To obtain a creamy mass, mix this solution thoroughly. This may take 5-10 minutes - it all depends on the amount of solution being prepared.
To ensure that the glue is completely ready for use, be sure to cool.

Wood glue at home

This is the most best glue for gluing wood. It effectively glues cardboard, paper and other materials. But this glue has several features of its own:

it cannot be stored for a long time in liquid form, because it spoils very quickly, becomes moldy, and also gels;
it has a pungent and disgusting smell.

Therefore, before you make this type of super glue with your own hands, immediately prepare the work area. There are a small number of ways in which it is possible to prepare high-quality wood glue, including long-term storage. The following methods are considered the most accessible.

Method one:

Take regular wood glue.
Grind and soak it in a container with water until it swells completely.
It must become soft, reminiscent of jellied meat.
Place this solution in a special container for melting, which is called a glue bottle. You can make it yourself from an ordinary tin can.
Place the prepared glue together with the prepared mass in a water bath, and then put it on very low heat.
Stir the mixture constantly using a stick made of wood.
If it burns, your glue will turn yellow and lose a significant part of its adhesive functions.
After this mass goes into required condition, dilute it with vodka in the proportion of 720 g of glue per 950 g of vodka.
Then, for every 100 g of glue, add 12 g of powdered alum.

Important! The wood glue obtained by this method provides sufficiently high strength to the bonded surfaces, and also has fairly good water-repellent functions.

Method two:

In an oilcloth, boil wood glue with water in a 1:1 ratio.
Wait until it starts to thicken.
Pour the mixture into a porcelain container and use a pestle to grind until the solution resembles a gelatinous mass.
After this, place the mixture on a special plate, cool and cut into pieces.

Important! If there is such a need, dissolve 720 g of the resulting glue in a mixture that consists of 720 g of water, as well as 360 g of vodka. Bring this mixture to a boil.

Foam glue

In order to insulate and soundproof residential premises, foam and polystyrene plates are often used. They are usually glued to load-bearing wall. When choosing adhesive for foam, keep in mind that solvents like acetone can melt it.

That is why the wood glue described above would be an ideal option for it. But at home you can prepare another waterproof paste for polystyrene foam, which consists of cottage cheese:

Mix in equal proportions slaked lime together with cottage cheese until a homogeneous mass is formed.
Use this glue immediately after you have finished preparing it because it hardens quite quickly.

Casein glue for wood, leather and puzzles

Quite a good option for gluing leather, as well as wooden products and other materials is casein glue. This glue can be successfully used when processing surfaces for puzzles. How to make this type of super glue at home?

First stage: isolation of casein directly from cottage cheese

In order to prepare it at home, the cottage cheese used must undergo a defatting process. To do this:

This powder is casein, and a solution based on it is an excellent option for making shoe glue at home.

Despite the fact that the selection of adhesive mixtures in stores is impressive, many builders prefer to make the compositions themselves from scrap materials. For different types surfaces prepare their own solutions. Let's take a closer look at how you can do this yourself.

Homemade flour glue

This is the most common composition used for wallpapering. Its properties are not inferior to many store-bought analogues, but at the same time it is environmentally friendly and safe to use.

To prepare the glue we need:

6 tbsp. l. flour
1 liter oxen.
container for mixing components.

1 liter of this mixture is enough to glue 2-3 rolls of wallpaper.

How to make glue from flour? Heat ¾ volume of water to a boil. Stir the flour in the remaining ¼ cold water until no lumps remain. Then pour the mixture of flour and water into boiling water in a stream, stirring constantly. After boiling, leave the glue to cool.

You can use starch instead of flour. The resulting solution will have similar properties.

Homemade PVA glue

Today this is one of the most popular compositions. In everyday life it is something universal. How to make PVA glue?

To do this you will need:

1 liter of water (preferably distilled)
5 g photographic gelatin
150 grams of flour
4 grams of pharmaceutical glycerin
20 ml ethyl alcohol

Gelatin should be soaked for a day in 1 glass of water. Then you can start preparing PVA glue. Place distilled water in a water bath and add gelatin and flour mixed in cold water. Mix everything thoroughly, preventing the formation of lumps. The resulting mixture should reach the consistency of sour cream and white. The next step is adding glycerin and alcohol. The time the mixture remains in the water bath should be approximately 10 minutes. In this case, the composition should be stirred constantly. Next, you should cool the glue and you can start using it.

How to prepare wood glue?

This solution is used to work with wooden surfaces paper, cardboard, plastic. However, it has weak points - the glue has a sharp unpleasant smell, not intended for long-term storage in liquid form.

You can solve the problem if you make a gelatinous mass by first boiling the wood glue. At the right time, you can cut off a piece and heat it over low heat.

Cooking options:

We take wood glue, grind it in water and wait until it swells completely. We place it in a tin can (cleaner) and place it in a water bath. As soon as the composition has become liquid, dilute it with vodka (based on 720 grams of wood glue - 950 grams of vodka) and add alum (per 100 grams of the mixture - 12 g of powdered alum). The resulting wood glue will have high degree adhesion and moisture resistance.
In a glass bottle, mix water and carpentry mixture in a 1:1 ratio. After boiling and thickening, pour the composition into a ceramic mortar and grind until a homogeneous gelatinous mass is formed. Then we put glue on the board and cut it into pieces.
In a water bath, heat the mixture at the rate of 1 liter of water, 1 kg of wood glue, 1 liter of 9% percent table vinegar. While stirring the solution, gradually pour in 1 liter of vodka, cool and use.
We dilute the wood glue with water 1:1 and heat it in a water bath until it thickens completely, then add glycerin in a volume equal to the volume of glue. Cook the mixture over low heat until the water has completely evaporated. Pour into molds and cool.

Adhesive based on linoleum and acetone

To prepare the composition in home conditions, take old linoleum and cut it into small pieces, then place it in a container and fill it with acetone in a ratio of 1:2 (1 part linoleum to 2 parts acetone). Seal the container tightly and place in a dark place for 12 hours. After this period, the mixture can be used.

How to make universal moisture-resistant glue?

For preparing universal moisture-resistant composition Just take the wood mixture and soak it in water until it swells completely. Next, the solution should be brought to a gelatinous state, heating over low heat and periodically pouring linseed oil at the rate of 1:4 (1 part oil to 4 parts glue).

In the process of completing many finishing works An essential component is glue. It is used to glue wallpaper, tiles, and is added to cement mortar. To save on purchasing glue, we suggest that you read the instructions on how to make glue yourself.

Functional features and chemical composition of the glue

Glue is a multicomponent composition based on compounds of organic or inorganic substances that easily glue materials together. of different origins, and in particular:

wooden,
leather,
fabric,
paper,
glass,
metal,
plastic,
ceramic,
rubber products.

The gluing process involves the formation of a strong bond between the adhesive on the two sides of the material to be bonded.

The chemical composition of the adhesive contains materials of artificial or synthetic, organic or inorganic origin. For example, the fairly popular silicone adhesive is based on compounds of elemental organics. To ensure that the consistency of the glue becomes liquid and is easily applied to the surface, it contains additives in the form of water and organic liquids.

Most sealants based on organic resins consist of water and are environmentally friendly.

Organic solvents are hydrocarbon substances of the aromatic or chlorinated type. Such solvents are quite affordable, easily evaporate, and non-toxic. The most common are gasoline, acetone or elite alcohol substance.

In order for the glue to become elastic, the presence of plasticizers is required. They act in the form of dibutyl phthalate, dioctyl phthalate, triphenyl phosphate. To reduce glue shrinkage, increase its strength and at the same time reduce cost, fillers are used. It is recommended to use kaolin as a filler, quartz sand, sawdust and other components.

If the adhesive is based on thermoactive resins, special catalyst-type hardeners 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 network structure are formed, which accompany a sharp increase in the adhesive bond before high or low temperatures.

The difference between catalysts and hardeners is that they are not able to enter into such reactions and do not accelerate the hardening process of the adhesive. Salt, peroxide, and acid are used as catalysts. The main requirement for using a catalyst is strict dosage. If the amount of catalyst is increased, the glue will practically not harden and the adhesive joint will remain weak.

Adhesives based on thermoactive resins are characterized by the introduction of catalysts, inhibitors or retarders to adjust the degree of hardening, to accelerate, slow down or stop the process of interaction between the accelerators and the main adhesive element.

To increase the viability of adhesives based on organic compounds, it is recommended to add antiseptics to them. Catalysts must be added to adhesives of polymer origin; they help increase their durability.

Main types of glue

According to the drying method, adhesives are divided into:

adhesives that are characterized by drying,
non-drying adhesives,
polymer compounds.

The first option, in turn, is divided into:

PVA glue,
silicate based adhesive,
glue carpentry purposes,
starch based glue.

1. Let’s start looking at the types of glue from the most popular PVA glue, which is an emulsion of polyvinylene and water, with a small amount of plasticizers and additives. The smell is practically not pronounced, it is used for gluing various substances.

There are these types of PVA glue:

household or wallpaper purposes - glues paper products, is used for decorating walls with wallpaper, looks like a white homogeneous mass, has a white or beige color, capable of defrosting and freezing six times;
stationery type - glues products made of paper, photo paper, cardboard, looks like a viscous liquid, color - white with a yellow tint, unstable to water and frost;
universal purpose - used for gluing wooden, paper, cardboard, leather, glass substances, is part of putty, primer, concrete mortar, has the appearance of a white, slightly yellowish viscous mass, characterized by the presence of six cycles of frost resistance;
PVA super glue glues wood, paper, glass, porcelain, leather, fabric, linoleum, tile products, frost-resistant;
PVA dispersion - appears in the form of an aqueous solution of polymers, which is stabilized with the help of a protective colloid, such as polyvinyl alcohol, has high adhesive ability, there are two types of dispersion: plasticized and unplasticized.

Scope of use of PVA glue:

as an additive to mortars;
in industrial establishments of textile, shoe, leather, printing origin;
in the manufacturing process of such products as: cigarettes, paints, industrial fabrics, household chemicals;
in the process of gluing paper, cardboard, and wooden parts.

Characteristics of PVA glue:

high level of frost resistance;
high adhesive ability;
environmental safety, non-toxicity, fire safety;
amenable to most organic solvents;
if you apply the glue thinly, it will be almost invisible after drying;
has no shrinkage.

2. Silicate glue is also called liquid glass, this material It is actively used both in everyday life and in industry, for gluing any parts.

Scope of use:

production of spraying for electrodes that are used in a welding machine;
in the mechanical engineering industry for delicate joining of parts;
in the pulp or paper industry;
in ferrous metallurgy and chemical industry;
is integral component most washing powders.

Peculiarities:

fire safety,
water resistance,
frost resistance,
resistance to acid solutions.

3. Wood glue is used for gluing wood parts. There are three types:

tiled,
chips,
granular

In relation to the composition, glue is distinguished:

vile,
bone type.

The first is stronger than bone, characterized by a greenish tint. Bone glue is orange-brown in color. Wood glue involves boiling it. Chip adhesive is boiled immediately, and tile adhesive is pre-crushed.

4. Starch-based glue is called paste, its production is quite simple, you need to mix starch with water and heat it until it becomes glue. Best qualities has a glue based on corn starch, and the worst ones are potato starch. It is recommended to use it within 24 hours.

Materials that will be required in the process of making 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 ethyl alcohol.

Pre-soak the gelatin in water for a day, it should swell. Gelatin must be photographic.

When the gelatin is ready to use, you need to build a water bath. To do this, take a pan of water and place it on the stove. Find a bowl that fits the diameter of the pan and place it on the surface so that it does not come into contact with the boiling water.

Place a mixture of water, flour and gelatin in a bowl and cook until it becomes thick like sour cream. This requires constant stirring. Remove the mixture from the heat and add alcohol and glycerin to it. Be sure to stir the mixture until it becomes homogeneous. When the glue has cooled, it is ready for use.

Before using it, the surface should be thoroughly cleaned of dirt and dust. If there are pores on it, prime them first. 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.

Flour glue is great for gluing paper products or wallpaper. Its production is a fairly quick process that will take no more than half an hour. Therefore, in a situation, for example, when you run out of wallpaper glue 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 paste:

Put the water on the fire and wait until it boils;
Separately, dilute the flour in a small amount of water;
pour the flour into boiling water and stir the liquid constantly;
wait until it boils and remove the glue from the stove;
wait for the glue to cool completely;
it is now ready to use.

The finished flour glue looks like thick jelly. As you can see in the answer to the question of how to make glue quickly, making this glue is the best option.

How to make glue from starch

The proportions of starch glue are the same as for flour glue:

for half a liter of water,
3 tablespoons cornstarch.

It is better to prepare glue in enamel or galvanized containers. Place a container of water on the fire and wait until it boils. Separately, dissolve the starch and pour it into the liquid. Wait until the glue boils and remove it from the heat.

The main advantage of starch glue is that it is more transparent and does not leave marks. It is recommended to use this glue completely without any residue, since over time it loses its abilities. To improve the quality of starch glue, it is recommended to add 50-100 grams of PVA glue to it.

If you add wood glue to this glue, it will do an excellent job of priming the walls before wallpapering.

How to make glue using acetone and old linoleum

This method makes it possible to prepare a universal adhesive material that has high level gluing.

To make glue at home using this method, first of all, you need to prepare the materials.

Linoleum should be cut into pieces measuring 3x3 cm. Then place it in a container that can be hermetically sealed. Take acetone, its amount should be twice the amount of linoleum. Pour acetone into a container with linoleum and place it in a place protected from direct contact. sun rays for twelve hours.

If, during this time, all the linoleum has managed to dissolve, use the glue for its intended purpose, otherwise, wait until the linoleum is completely dissolved.

Scope of use - gluing:

wooden,
porcelain,
metal,
leather parts.

How to make paper glue

If you are interested in origami, quilling or appliqué, this glue recipe is ideal for gluing wooden parts. It is based on the use of dextrin, which is also easy to prepare at home.

This requires:

take a few tablespoons of starch,
put it in a heat-resistant container,
heat gradually in the oven,
bring the temperature to 150 degrees,
leave for 90 minutes.

To prepare glue, you must have:

three tablespoons of dextrin,
five tablespoons of water,
one tablespoon of glycerin.

The first step is to mix dextrin with water. The mixture is heated until the dextrin is completely dissolved, requiring constant stirring. At the end of cooking, glycerin is added. After cooling, the glue is ready for use.

How to make titanium glue

To prepare such glue you will need chemical substance vinyl acetate copolymers. It is very difficult to get, so making such glue at home is quite difficult.

Let's consider the advantages and features of titanium glue of industrial origin:

appears to be a clear liquid
frost-resistant,
waterproof,
heat resistant,
used in the process of gluing ceiling tiles,
convenient to use.

Making your own wood glue

The process of preparing wood glue is simple, and allows you to make glue that can easily glue any wooden parts. But at the same time, this glue has its drawbacks:

fast shelf life,
presence of a disgusting, pungent odor.

Therefore, in the process of cooking it, a special mass is produced, which has a greater speed of shelf life. This mass is solid and is cut into pieces, which are boiled for their further use in the form of glue.

Let's look at the four most popular methods of making wood glue:

1. Take standard wood glue. Chop it and leave it in the water. Wait until it swells. When the mixture becomes soft, place it in a glass bottle. This is the name of the tank in which the melting process is carried out. Take tin can and pour the liquid into it. Place it in a water bath, stirring constantly until the glue becomes liquid. For 360 grams of glue, take 475 grams of vodka and combine them. Then you should add 100 grams of powdered alum. This glue has water-repellent properties and is characterized by a high level of strength.

2. Dilute equal amounts of glue and purified water in a metal container. When the mixture thickens, put it in a mortar and grind. Pour the mixture into a plate and wait until it thickens completely. After cooling, this mass 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 glue after cooling.

3. Prepare a water bath. For half a liter of water, take half a kilogram of glue and half a spoon of vinegar. Cook until the glue dissolves, then add half a liter of vodka.

4. For 250 grams of glue, take 250 grams of water, bring to thickening. At the end of cooking, add 250 grams of glycerin. Wait until the water evaporates. Place glue in the mold and use as needed. To use this glue you need to dilute it with water in a one to one ratio.

Glue is a substance used in household, as well as in almost all areas of production. The reason for the high popularity of the adhesive is the ability to connect objects of different composition, dimensions and shapes. Modern varieties adhesives provide high aesthetics and reliability.

Before you start making PVA glue with your own efforts, you need to understand why such “creativity” is even necessary. Self-production The adhesive composition will be relevant in the case when a person has doubts about the quality of the purchased analogues or they are not available for sale at all.

Main characteristics of PVA glue

Among other things, glue own production you can add additional properties (for example, paint it in light shades). This can be achieved by changing the recipe. When pasting walls with thin rolls of paper or applying liquid wallpaper Matching the adhesive to their color will greatly simplify the work. Such a high popularity of Poly Vinyl Acetate emulsion, which has water base, is associated with its excellent characteristics:

Frost resistance - it is necessary to keep in mind that this refers to the resistance to freezing of the adhesive layer that has already been applied. If PVA is in liquid form, it should not be allowed to freeze. If a container with polyvinyl acetate glue is kept in a cellar or garage in cold weather, then in the spring you will simply have to throw it away - the liquid, which will be thawed, will lose its original properties and will not glue even thin wallpaper;
Good adhesive ability. In order for all parts of the adhesive assembly to be reliably connected, a relatively small volume of glue is needed, and after tightly connecting the parts, it is problematic to break them (more often, breaks are observed in the main material, and not along the edges, which are treated with glue). According to existing standards for industrial compounds, the breaking force of treated compounds is from 400 to 559 N/m. Glue made at home will be just as reliable, but subject to full compliance with production technology;
Safety during operations, storage and production. Not available in PVA toxic substances, does not emit harmful compounds and is fire resistant. It does not harm the skin. In this case, it is better to protect your eyes from splashes, but even in the event of such a problem, it is easy to correct the situation - to do this, simply rinse your eyesight with water. In this way they will not be harmed;
Solubility in plain water and compatibility with organic solvents - acetone, methanol, benzene and so on. If toxic substances are used when diluting PVA, then they negative impact emulsion absorbs onto a person;
Due to the good strength of the applied thin layer, this glue is indispensable for small thicknesses of the surface to be glued;
After polyvinyl acetate dries, there is no shrinkage or formation of cavities. Excess glue can be easily removed from the surface with a simple sponge, which will in no way harm the delicate coating (thin paper, wallpaper glitter);
The dried mass is quite strong; it can fill minor installation gaps (up to two millimeters). This quality is especially valued when treating walls with wallpaper (primarily this concerns the coloring of non-woven materials) - in this way it is possible to minimize existing errors such as joints of different thicknesses.

We make glue for different occasions

The collective name “PVA” can be applied to a fairly wide group of adhesive solutions, the recipes of which are almost one hundred percent similar. Their area of use is indicated by the letter designation - this information must be indicated in technical documentation, as well as on the packaging itself:

PVA-K is a simple composition that has clerical purposes. A flowing liquid of a white (sometimes yellow tones are acceptable) shade, without lumps; in some situations, a film may be present on the surface. This composition does not withstand exposure to water, and the glued surfaces begin to come off even with a slight drop in temperature. Due to the fact that when producing this variety they save on plasticizers, it distinctive feature is low cost. But such glue can only be used for office purposes - gluing thin cardboard and sheets of up to A4 format;
PVA-O is a wallpaper composition (household), which is an improved version of the previous one. It copes well with moisture, the surfaces on which the composition is applied can be frozen down to -30 degrees without fear. Typically used for treating putty, wood and concrete surfaces wallpaper strips with a paper backing. The exception, perhaps, is massive rolls - for these purposes it is better to take special compounds or liquid nails;
MB - this recipe is considered universal. Compatible with paper products, leather, wood, fabric, glass and even metal. After application, withstands temperatures down to -20C;
M – so-called super-PVA – universal adhesive with improved properties. Frost-resistant down to -40C. Due to its moisture resistance and strength, such a composition is ideal for not only any type of wallpaper, but also facing tiles and linoleum (the only exceptions are rooms in which high humidity is constantly observed);
Dispersion is a low-water composition intended for any polyvinyl acetate emulsion.

It consists of colloidal and polymeric substances. Distinctive Features– quick gluing; when conducting an experiment, fingers are glued to each other in a matter of seconds. The scope of application is wide - the substance is added to plaster solutions, used in the leather, shoe industries and many other areas.

Any PVA glue in pure form Should be used only at positive temperatures. Included construction fundamentals the use of dispersion does not have climatic standards.

Making PVA glue at home

In order to understand how to make such a substance with my own hands, you need to acquire a minimum set of required components. For a liter of aqueous solution you will need:

White, well-sifted wheat flour - one hundred grams;
Ethyl alcohol (even technical alcohol will do) - about twenty grams;
Fine gelatin (also called photographic) - no more than ten grams;
Simple glycerin;
Organic coloring pigments of light shades - if necessary.

A preliminary step is required when producing an aqueous solution of gelatin - it must be diluted in a ratio of ten grams of liquid per 1 gram of dry mixture. The solution is left in this form for a day. If the jelly ends up being thick (due to various quality basics), it gets divorced hot water and mixes well. All other manipulations are carried out only after a day.

It is necessary to prepare several enamel vessels, and they must be structurally combined with each other. The thing is that PVA, which is made in an “artisanal” way, must be boiled in a water bath. The gelatin solution and liquid are poured into a smaller container. Then we place it in a large vessel filled with reins and place it on high heat.
The mixture of gelatin and liquid is brought to a boil and only after that you can begin to gradually add flour. This process is similar to preparing semolina porridge - if you want the “dish” to come out without lumps, you will have to stir all the time. Only, unlike semolina, it will take at least an hour for flour to completely dissolve in gelatinous water (do not forget that during this time the adhesive composition must be stirred with a wooden spoon).

Once you achieve the required consistency (thick sour cream), it’s the turn of alcohol, dyes and glycerin. After adding such substances, homemade PVA is still kept in a water bath for about thirty minutes, remembering to mix thoroughly. Then all that remains is to leave the prepared solution and then test its adhesive abilities.

Preparing the paste

Here you will need:

Rye or wheat flour (starch will do);
Galvanized or enameled cookware;
Water;
Gauze.

Preparation

Two-thirds of the vessel is filled with water;
As soon as the water boils, flour is poured into it. The solution is brought to a homogeneous mass that resembles dough (but if starch is used, you should get a translucent brown solution);
Let the composition cool to thirty degrees;
The mass is filtered.

The glue is ready for use (don't forget that it can only be used after it has cooled).

To improve bonding properties, simply add a small amount of PVA to the solution.

If you plan to glue wallpaper with boiled paste, then it is better to prepare it using starch. In addition, any composition must be filtered before use. Do not forget that the shelf life of such a substance is one day. Therefore, use it immediately after cooling.

After the manufacturing procedure is completed, be sure to ventilate the room. It is better to pour the cooled product into convenient jars of a suitable size. Store the composition in a tight container and with the lid closed, otherwise it will simply dry out. Before applying the composition to the surface, mix it thoroughly in a container. wooden stick and apply a small amount. The surfaces to be glued must be pre-treated - degreased, remove the layer old paint and so on.

The glue is stored for no more than six months at a temperature of ten to fifteen degrees. If these indicators are lower, then it will last no more than a couple of months.
As you can see, there is nothing complicated to make on our own There is no PVA or any other type of glue.
