How to make PVA glue at home - step by step instructions and a detailed review of the best glue recipes. How to make DIY wallpaper paste from flour and starch

PVA glue will help you glue paper and plastic figures, wooden details and fix various things needed in the household. We will tell you how to make PVA glue yourself, and you do not need to run to the store for it during the repair. Homemade glue can be used both for wallpapering in the house and as a surface primer before finishing.

How to make PVA glue - what you need for this

Prepare the following ingredients for making glue:

1 liter of distilled water;
100 g wheat flour. Sift the flour well before making the glue;
4 g of glycerin. Buy at the pharmacy;
20 ml of ethyl alcohol. Also sold in pharmacies. You can replace with technical alcohol, as a last resort;
5 g photographic gelatin. Buy from a store that sells camera supplies.

How to make PVA glue - preparation

The preparation of PVA glue can be divided into two stages - preparation and its direct manufacture. Preparation consists in soaking gelatin:

pour distilled or plain water into a glass;
pour gelatin into the water;
leave to swell for a day.

If the jelly is too thick - dilute hot water and mix well. The rest of the manipulations are carried out on the second day.

How to make PVA glue - the cooking process

Prepare two ahead enamel pots- one is larger and the other is smaller so that it enters the first. You will cook in a water bath. After the gelatin swells, we proceed to the preparation of the glue:

pour distilled water into a smaller enamel bowl and place in another bowl in a water bath on the stove;
gradually add swollen gelatin and flour, mixed with a small amount of ordinary water, into distilled water. See that there are no lumps in the flour mixture;
bring the mixture to a boil. But you do not need to boil and stir constantly so that there are no lumps. The mixture should be the consistency of homemade sour cream. Remove from the water bath after obtaining the desired consistency;
cool slightly and add alcohol and glycerin in turn to the mixture. Mix thoroughly to get a thick homogeneous mass. Stirring time is up to 10 minutes, three stirring with a spoon is not enough.

Let the glue cool and use as directed.

After finishing the preparation of the glue, ventilate the room. Pour the cooled product into convenient suitable jars. Keep the glue in a tight container with a closed lid, otherwise it will dry out. Before applying it to the surface, stir well in a jar with a stick and then apply a small amount of glue. Initially prepare the surfaces to be glued - degrease, remove old paint etc. Store glue no more than 6 months at a temperature of 10 to 15 degrees Celsius. With more low temperatures ah, it is stored no more than two months.

You will need few materials for making homemade PVA glue, and making it is simple and quick. Most importantly, follow all the above proportions of the ingredients and constantly stir the adhesive mass during the cooking process.

Before puzzling over the question of how to dilute PVA glue with your own hands, decide for what work you need it. Your own prepared composition can only be justified if you are not sure of the quality of the material from the hardware store counter.

It's not news to anyone that the use of PVA glue is very diverse, both for outdoor work and for indoor use. Therefore, further we will talk in more detail about what PVA glue is, how to prepare it at home and for what work it can be used.

Making PVA glue

What is PVA?

Do-it-yourself PVA glue

PVA - polyvinyl acetate, which includes an emulsion and various plasticizers and additives that increase the adhesive properties of the mixture.

Any adhesive solution can be diluted in various proportions with various additives, which can give the adhesive unique features and change its color. If you plan to apply liquid wallpaper to the walls or glue thin-layer paper wallpaper, glue of the right color will greatly facilitate your work.

To explain why PVA glue is so popular, its properties that kmts glue cannot boast of will help:

Frost resistance

Here we are talking about the resistance to frost of an already applied layer of glue. If the adhesive complies with GOST y, in liquid form it is afraid of low temperatures. Therefore, if you store the substance in a cold place, you can safely throw it away, because all its adhesive abilities will be lost.

High adhesive ability

According to GOST, industrial PVA glue has a rupture strength of the glued joint of about 550 N / m. But, do-it-yourself glue is not inferior in its strength, if all the cooking technology is followed. Therefore, it can be used to glue fiberglass on walls, use the substance as an adhesive for polystyrene foam and as an adhesive for extruded polystyrene foam.

The material is safe to store, manufacture and use

Since the substance does not contain toxic, flammable and other harmful components, it will not harm your skin. One but! Protect your eyes when working, because even a small drop of glue that gets into the eye will not bring anything good. But, even if such a nuisance happened to you - do not panic, rinse your eyes well enough running water and your eyesight will not be affected in any way.

The mass is highly soluble in water and easily comes into contact with an organic solvent.

The substance is easily combined with benzene, methanol, acetone and other solvents. But, pay attention, if the glue is diluted with a toxic solvent, the whole mixture will also become dangerous to human health.

After drying, the substance does not shrink and does not form cavities. If in the course of work you have formed excess substances, they can be easily removed with a sponge.
After drying, a sufficiently strong mass is obtained, which can be used to fill various mounting gaps, the size of which is up to 2 mm.

I would also like to note that with the help of glue you can smooth out small errors that formed a joint of different thicknesses.

How to prepare glue for different jobs?

You can talk about what kind of work this or that adhesive solution is intended for immediately after you see the first letter of the abbreviation, which is spelled out in GOST e.

According to GOST, there are such types of glue:

PBA-K - substance for clerical work;
PBA-B and PBA-O - wallpaper paste (modified clerical);
PBA-MB is a universal composition that can be used on paper, wood, leather, fabric and metal. Also, the substance can be used to glue extruded polystyrene foam, pvc, osb, osb.
PBA-M is a super PVA glue, an improved universal composition that is great for osb boards and is widely used as an adhesive for plastic corners;
dispersion - low water base for polyvinyl acetate emulsion.

About what features PVA glue has and specifications stated in the table below.

Please note that pva, like kmts glue, must be used at positive temperatures. But if the substance is in the composition mortars, this restriction is lifted.

In this section, we talked about gluing different materials, but what to glue and how to glue fiberglass? Fiberglass is a kind of cobweb, which is used to align the walls before wallpapering. For gluing such material, you can use both a special substance that is sold complete with a canvas, and ordinary PVA glue.

How to make glue with your own hands?

Making PVA glue at home

To dilute or prepare 1 liter of glue with your own hands, you will need the following set of components:

100 g white, well-sifted wheat flour;
20-30 g of ethyl alcohol (technical);
5-10 g of finely dispersed gelatin;
5-10 g of glycerin;
if necessary, a light-colored organic dye.

And so, how to cook glue from flour? First of all, you need to dilute the gelatin with water and leave the gruel for 24 hours. If the substance turned out to be too thick, it can be stirred with hot water, breaking all the lumps. All subsequent actions will be foreseen at the end of the day.

To prepare the glue, we need 2 containers (preferably enameled). I would like to immediately note that the glue is boiled in a water bath. For cooking, pre-soaked gelatin is poured into a smaller container, and water is poured into a large one and put on fire.

Bring the gelatin mass to a boil, then add flour a little at a time. The technology for performing work is similar to cooking semolina, so be prepared for constant stirring so that lumps do not form. It will take you about 60 minutes to cook.

When the solution is cooked and you get the desired consistency, you will need to add alcohol, pigments and glycerin to the gruel. After adding these components, the glue is kept in a water bath for about half an hour, stirring all the time.

Upon completion of all manipulations, the agent is cooled and it is checked whether the adhesive properties have been achieved.

If the mass is cooked correctly, it can be stored in liquid form for six months, tightly closing the neck and preventing it from hypothermia.

If cooking glue from flour is unacceptable to you, as it requires a lot of time, check out how to cook glue from starch. For this you will not need any additional components - only hot water and starch, the adhesive features from such a small variety of ingredients will not decrease.

If you plan to use the substance only for wallpapering, prepare kmts glue, which is also easy to make at home.

Well, now you know how to make PVA glue at home, and we hope that our tips will help you cope with this task. The main task is to observe all proportions and do not forget to mix the mass thoroughly - this is what will help you create a homogeneous and effective substance.

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 simply incorrectly calculated the required volume for work, but need to increase it. In order not to quit already and not to run headlong to the store, you can make homemade glue, which in its quality will be better than the purchased one. We offer you in this article a few proven recipes in practice. various kinds glue.

The traditional recipe for making wallpaper paste from flour

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

In order to prepare it, you will need:

any container, the volume of which will be sufficient for the required amount of glue;
wheat flour - 6 tbsp. l.;
water - 1 l.

Preparation procedure:

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

Important! In already ready-made such glue must necessarily have the consistency of a fairly thick jelly. Similarly, you can make glue from starch, which will not differ in quality from flour glue.

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

We prepare PVA glue from improvised means

The most common adhesive, which is widely used not only during the run repair work at home, but also in large-scale buildings, is PVA glue. This is rightfully a super-glue, which is very easy to make with your own hands, and the range of applications of which is so versatile 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 solutions for tiling, as a primer for surfaces, before proceeding to the final finish.
It is also used for gluing various elements of furniture, interior items.

Important! It can be said with full 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 of gelatin, which is intended for photographs;
4-5 g of pharmacy glycerin;
wheat flour 100 g;
20 ml of ethyl alcohol, which can be purchased at a pharmacy.

Glue preparation occurs in 2 stages:

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

Place the container 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 whole mixture to a boil, but in no case boil. It should definitely become like thick sour cream.
In order for the mixture to be homogeneous, stirring it constantly.
Add glycerin as well as 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.
For its complete readiness for use, be sure to cool the glue.

Carpentry 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 deteriorates very quickly, becomes moldy, and it is also gelatinous;
it has a strong and disgusting smell.

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

Method one:

Take ordinary wood glue.
Grind and soak it in a container with water until it swells completely.
It must definitely become soft, reminiscent of jelly.
Place this solution in a special container for melting, which is called kleyanka. It can be made independently from an ordinary tin can.
Place the prepared oilcloth together with the prepared mass in a water bath, and then put on a very slow fire.
Stir the mass constantly with a stick, which is made of wood.
In the event that it burns, your glue will turn yellow and lose a significant part of its adhesive functions.
After given mass will go into the required state, 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 carpentry glue obtained by this method provides a sufficiently high strength to the surfaces to be glued, and also has fairly good water-repellent functions.

Method two:

Boil carpenter's glue with water in a 1:1 ratio in an oilcloth.
Wait until it starts to thicken.
Pour the mass into a porcelain container and rub with a pestle until the solution resembles a gelatinous mass.
After that, put 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.

Styrofoam Adhesive

In order to insulate and soundproof living quarters, foam plastic plates, as well as polystyrene foam, are often used. They are usually glued to bearing wall. When choosing a foam adhesive, keep in mind that solvents like acetone can melt it.

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

In equal proportions, mix the slaked lime with the curd 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

A fairly good option for gluing leather, as well as wooden products and other materials is casein glue. This adhesive can be successfully used during surface treatment for puzzles. How to make this type of super glue at home?

First step: isolating the casein directly from the curd

In order to cook it at home, the used cottage cheese must necessarily go through a degreasing process. To do this:

This powder is casein, and a casein-based solution is a great option to make shoe glue at home.

At home often there is a need to glue or glue this or that object made of wood, plastic, rubber, fabric, etc. The industry produces ready-made glue for various purposes. In this case, you can use improvised means and make glue yourself.

Wood glue indispensable for gluing wood, paper, cardboard. When using wood glue, it is better to use glue that has been previously welded and then dissolved as needed over a fire. Cooking wood glue should be in special utensils(glue), which is not difficult to make from two cans (the principle of a water bath). 10-12 hours before cooking, the glue tile should be broken into small pieces, pour them into the oilcloth and pour cold water so that all the glue is covered with it. Then, when the glue absorbs all the water and turns into a gelatinous mass, pour into the outer bowl of the oilcloth hot water and put on a light fire. Depending on the desired density, hot water can be added to the glue. When heated, the glue must be constantly stirred with a stick to prevent it from burning, otherwise it becomes dark and loses some of its gluing power. Carpentry glue should not boil. When there are no lumps left in the mass of glue, it is ready. The welded glue is poured onto a plate, on which it is allowed to cool. It turns out a gelatinous mass, from which pieces are cut off and dissolved by heating.

For bonding leather glycerin should be added to the wood glue (a teaspoon per half liter of glue).

To improve the quality of wood glue use the following helpful hints. Ordinary wood glue is soaked in water until it swells and turns into a relatively soft mass. After that, draining the water, melt it on the fire carefully and not for long so that it does not burn. After pickling, the glue is diluted not with water, but with vodka, and 12 g of powdered alum is added for another 100 g of wood glue. The glue prepared in this way is very durable and resists well to water.

starch paste mainly used for bonding paper. It should be prepared like this. Take four teaspoons of potato or wheat flour in half a glass of cold water and mix thoroughly so that there are no lumps. After that, you need to pour in boiling water, stirring constantly. wooden stick(The metal spoon will heat up quickly and you won't be able to hold it.) A well-prepared paste should be transparent and resemble thick jelly. The paste quickly deteriorates and loses its adhesive properties, so it should not be prepared in reserve.

When sticking paper on cardboard always grease paper with paste, not cardboard. The paper is allowed to lie down for 1-2 minutes and only then it is applied and rubbed.

casein glue glues the same objects as carpentry, but has the advantage that it is less afraid of moisture.
Preparing casein glue is quite simple. To do this, pour casein powder into a flat dish (plate, bowl, saucer) (it should be yellow or whitish in color, without lumps), then gradually add cold water, stirring constantly, until a mass of such density as sour cream is obtained.
It is necessary to stir casein glue as long as possible, in any case, at least half an hour, since the quality of gluing depends on this.

Casein is easy to prepare from fat-free cottage cheese, which is squeezed out in cheesecloth for this, washed well in water with a small amount of soda, and then in clean water, squeezed hard and dried; after complete drying, grind into powder and sift.

Another way to prepare casein glue. Take cottage cheese (casein) and gradually add it to a saturated solution of borax until the curd ceases to dissolve. You will get a thick transparent liquid with high adhesiveness, suitable for sticking labels, postage stamps, etc. Before sticking, the object should be slightly moistened. Adding a few drops of liquid formalin will keep the quality of this glue for a long time.

Dextrin glue can successfully glue paper, cardboard, fabrics, leather, etc.
Dextrin glue is prepared as follows: 3 tablespoons of dextrin are kneaded in 4-5 tablespoons of cold water, heated, stirring constantly, and a tablespoon of glycerin is added. Store in a well-sealed container. Use cold glue.

Dextrin is made from starch which is placed in a porcelain or enameled container and placed in the oven (oven). The temperature in the oven is gradually raised to 160°C. At this temperature, the starch is kept for 1 hour and 45 minutes. Starch in the process of thermal splitting acquires a yellowish color. In this state, it turns into dextrin. With a weaker heating, the splitting process is slower, and with a stronger one, the starch burns.

celluloid glue recommended for bonding celluloid, paper and plastics. You can prepare it from an old photographic film. First you need to soak it in warm water, wash off the emulsion from it, then cut into small pieces, put in a vial with a ground stopper and pour acetone (you can use a solution for washing off nail polish). The amount of acetone should be twice the volume of the film. The vial must be tightly closed and allowed to stand, occasionally shaking. When the film is completely dissolved, the glue is ready. In density, it should resemble liquid sour cream. Although the vial is closed with a ground cork, its neck should be wrapped with a staniole (chocolate wrapper) or tied with parchment paper.

Waterproof adhesive. To prepare a glue that is not afraid of moisture, you can use freshly curdled milk or cottage cheese, which is mixed with slaked lime to obtain a homogeneous thick mass. The resulting mass is applied evenly, thin layer on glued wooden surfaces, which are then strongly compressed and dried.
Another way: 100 g of good carpentry glue is boiled in a glass of water until molasses thickens and then 35 g of drying oil is dissolved in it. Use this glue in a heated state. Parts of the tree glued with this glue are not afraid of either cold or hot water and become absolutely impenetrable from it.

Glue for rubber. A piece of soft rubber is crushed into small pieces, which are insisted for several days on clean, light (aviation) gasoline.
The result is a rubber solution, which is carefully drained, filtered and left open in a warm place until a thick mass is obtained. It is also used for bonding rubber products. The surfaces to be joined must be free of grease.

Some items can be glued without the use of factory glue, using improvised means.

Porcelain and faience can be glued with cottage cheese, diluted ammonia until the thickness of the gruel. The thing intended for gluing must be cleaned along the edges of the fault, greased with gruel, tied tightly and allowed to dry. There is another way. Gently fold the broken earthenware (small) thing, tie it tightly and lower it into boiling milk for several minutes, then take it out and leave it to dry for a day.

Porcelain can be glued prepared at home from dry casein powder (20 g), sifted slaked lime (6 g) washing soda (10 g), which are kneaded with 8 g of office glue and 8 g of water until sour cream is thick.

Glass it is recommended to stick together with gelatin, to which a small amount of an aqueous solution of potassium dichromate (potassium bichromate) is added. The glued object must be placed in the bright sun: under the influence of light, the glue becomes insoluble and withstands hot water.

Conducting redecorating with your own hands, sometimes a small amount of wallpaper glue is required.

Buying an expensive box that is not useful in its entirety in this situation does not make sense.

You can prepare a wallpaper paste from improvised materials, while saving the family budget.

Consider how to make a paste, classic recipes for homemade glue, its advantages and disadvantages.

Preparation methods and compositions

The density of dilution of the cool powder depends on the type of wallpaper, the heavier the canvas, the less water needs to be added

Not so long ago, our grandmothers and mothers glued all the wallpaper on the paste, without using ready-made mixtures. do it yourself is not difficult.

Environmentally friendly glue, prepared at home, does not give up its position today. Using it, you can be absolutely sure of the safety of the adhesive.

It may contain starch and flour at the same time, or only one product can be used. Depending on the type of wallpaper, a solution of various densities is prepared.

If desired, the paste can be strengthened by adding a little PVA or wood glue to it. These additives will make ordinary paste more resistant to moisture.

flour glue

Dissolve flour in cold water

How to prepare a paste yourself? Classic recipe flour paste at home is easy to perform. To prepare 1 liter of paste, we need 200 g of flour.

To avoid unnecessary time and material costs, you should adhere to the following instructions:

sift the flour through a fine sieve;
carefully dissolve the flour in a small amount of cold water;
1 liter of water must be boiled;
pour boiling water in a thin stream into the flour solution; put the composition on a slow fire and, with constant stirring, bring to a boil;
remove from heat, let cool slightly and remove the resulting film;
we filter the prepared mass through a sieve.

The glue is ready to use. If the composition turned out to be very thick, just dilute with water. Checking the consistency is very easy. The solution should drain from the fingers.

If the fingers stick together slightly when unclenched, then everything is done correctly.

It is better to use flour 1, not premium. A coarse grind mixture will provide better adhesion.

It is worth preparing the glue immediately before use, the composition is not stored for long. Within a day, its adhesive properties will deteriorate greatly.

Starch-based composition and mixed appearance

Pour the starch mixture in a thin stream into the hot water.

Starch-based glue at home is performed in a similar way with a floury look. Proportions for its preparation: 1 to 10, i.e. to prepare 1 liter of paste, you need 100 g of potato or corn starch.

You can improve the composition by mixing flour and starch. Such a paste is prepared by brewing:

in a small bowl, mix 1 cup of flour and 2 tablespoons of starch;
boil 2.5 liters of water and leave on low heat;
when the water in the pan boils, pour cold water into a bowl with starch and flour in a thin stream and mix thoroughly;
pour into the resulting mixture into hot water, stirring constantly, let it boil and remove from heat;
after cooling, the composition must be filtered. For more information on cooking, see this video:

Many believe that the paste must be welded. IN this recipe You do not need to boil the mixture, you just need to bring it to a boil and immediately remove it from the heat.

Advantages of home glue

The shelf life of this adhesive is very short.

In addition to the obvious advantages in the simplicity and economy of preparation, do-it-yourself wallpaper glue has a lot of other advantages:

№	Excellent adhesion	Using a paste, you can stick wallpaper on any type of surface, even if it is treated with drying oil or oil paint.
1	Safety and environmental friendliness	All components of the paste are not only safe, in fact they are edible. Such glue can be safely used in children's rooms and bedrooms. It will not cause allergic reactions, does not emit harmful substances or unpleasant odors. It is absolutely harmless in case of contact with the skin during operation.
2	Versatility	Suitable for use with wallpapers of any type, except for heavy types. The dried glue is not inferior in strength to industrial mixtures.
3	Ease of removal	Despite the strength, the wallpaper glued with paste is easy to remove from the wall, it is enough to wet the canvas.
4	Not aggressive	The paste does not destroy the structure paper wallpaper, does not cause soaking, which reduces the risk of damage to the canvas when sticking to the wall.
5	not noticeable	The paste solution has a slightly cloudy whitish color, it disappears when it dries. Getting on a cloth of wall-paper, does not leave marks.

There is a paste cooked at home, and disadvantages, not to mention which would not be fair. The main problem is the fear of water.

Do not use flour or starch-based adhesives in damp areas.

To give greater resistance to moisture, you can add PVA glue to the paste at the rate of 100 ml per 5 l finished glue. This composition can be or paper wallpaper.

The paste has a very short time beneficial use, its shelf life is not more than 24 hours.
