How to weld glue at home. How to make glue from flour yourself

It often happens that during the repair process there is not enough adhesive or glue with the necessary characteristics I can't buy it in the store. In such situations, you can make PVA glue yourself, that is, in normal home conditions. And in order to make high-quality PVA glue, you will need a base that is available in every housewife’s kitchen.

Types of PVA glue

The modern consumer can purchase several options for the adhesive base:

1. PVA stationery. The adhesive has a non-waterproof base and is not allowed to be used outside the house.
2. Household PVA glue, which is most often used for wallpapering. This type The adhesive base has increased frost resistance and retains its properties at temperatures down to minus 25 degrees.
3. The product is brand “M”, super frost-resistant. It is allowed to apply them to surfaces at temperatures down to minus 35 degrees.

Any type of adhesive base provides many advantages:

• resistance to chemical reactions;
• fast setting process;
• lack of specific odor;
• non-toxic base.

The only drawback is its low water resistance. However, thanks to the additional components that manufacturers add to the base, the water resistance coefficient of PVA glue has increased significantly.

Making your own adhesive base

As mentioned earlier, if you don’t have the required amount of adhesive on hand, you can quite easily make it yourself, at home. To make high-quality PVA glue, you should prepare the following ingredients:

• distilled water (1-1.2 liters);
• photographic type gelatin (approximately 5-6 g);
• regular glycerin sold in pharmacies (4-5 g);
• wheat base flour (100-120 g);
• ethyl alcohol (20-25 ml).

It is quite easy to buy any ingredient, except photographic gelatin, by visiting a nearby store or pharmacy kiosk. A the right type gelatin should be purchased in advance at a specialty store.

To make high-quality PVA glue at home, you need to follow the recommendations of experts, which you can read on the website at a time convenient for you. Step-by-step instruction preparing the adhesive base at home under normal conditions will be something like this:

• pre-purchased gelatin must be soaked in plain water for approximately 24 hours;
• after the allotted time, you need to dissolve the gelatin base in a water bath;
• all the ingredients included in the PVA glue base are added to the dissolved component, except for regular glycerin and ethyl alcohol;
• All ingredients are boiled until the mass acquires the thickness of sour cream, while 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, and 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; you can use the adhesive in normal home conditions after the mass has completely cooled. It is difficult to refute the obvious fact, which indicates that anyone can make high-quality PVA glue from simple and accessible ingredients.

To use a base for gluing, it is important not only to make high-quality glue at home, but also to properly prepare the surface to be treated. Experts recommend doing the following before gluing:

• Thoroughly remove any type of dirt and dust from the surface;
• if the surface has a porous base, it must be treated with primer;
• existing old paint must be eliminated, the surface must be degreased with a special compound;
• Before application, the adhesive should be thoroughly mixed in the container, and a small amount of glue should be applied to the desired element;
• All elements that need to be glued together should be pressed tightly together or a special weight should be placed on them.

Repairs are always troublesome undertakings, which, in addition to hard work, also involve large financial costs. Every person tries to save on every little thing. If you will be gluing wallpaper on the walls, you can make the glue yourself.

Ingredients for cooking adhesive composition

The quality of the resulting product will not be inferior to ready-made adhesives, but you will definitely be able to save money.

The classic recipe for obtaining an adhesive composition

This wallpaper glue can be made from flour. It is actively used for gluing paper wallpaper. The main advantage of this composition remains its non-toxicity, so it is absolutely safe to use at home. As mentioned above, the main ingredient is flour, which can be found in any home. Before making glue, it is necessary to determine the consumption of the adhesive composition. To glue 2.3 rolls of wallpaper, you need 1 liter of glue.

Main component adhesive composition

To prepare the composition you need to take the following elements:

• container for receiving glue;
• flour in the amount of 60 g and 1 liter of water.

To make wallpaper adhesive at home, you can use the following action plan:

1. Heat the water until it begins to boil. Take another container, combine flour and cold water to form a mixture with a consistency similar to sour cream. Make sure that there are no lumps in the prepared product.
2. Pour hot water into the resulting mixture in a thin stream, stirring with a spoon all the time.
3. When everything is stirred, put the container back on the fire, wait until it boils and use after cooling.

The resulting homemade glue should have a consistency similar to thick jelly. You can prepare wallpaper adhesive using not only flour, but also starch. In terms of their properties, these two adhesives are no different, but they can compete with many industrial compounds, for example, such as.

The required consistency of the adhesive composition, you can start repair work

If you are afraid to distribute glue on the canvas, you can test it a little first. Apply the composition to two small pieces of wallpaper, and then glue them together.

You can glue the canvases on any surface, and also achieve excellent adhesion of paper and cardboard. In general, conduct experiments and see for yourself the high quality of homemade wallpaper glue.

PVA glue

The next adhesive that you can make yourself is called PVA glue. Many people believe that at the factory this composition for gluing wallpaper is made using some special technology. This opinion is erroneous, since it is possible to make a similar composition at home and save money.

Factory packaging of PVA glue

This product is considered the most widespread today. In addition to wallpapering, it is actively used in office supplies and construction. For this reason, PVA glue can safely be called unique. If you are interested in such a product, then it is worth considering the recipe according to which it is prepared:

• purified water – 1 l;
• photographic gelatin – 5 g, you can really find it in a store that sells products for cameras;
• glycerin, sold in pharmacies – 4 g;
• wheat flour from grocery store– 100-150 g;
• alcohol – 20 ml.

The process of preparing PVA glue is conventionally divided into two stages. The first is a pre-done job that involves the procedure of soaking gelatin. To do this, you need to take a glass of water and send the presented product there. The second stage is the actual preparation.

PVA glue for household use, for housework

When the gelatin has swollen (about a day), you can prepare the glue:

1. Take distilled water and heat it in a water bath. After this, you should send the gelatin there, mix thoroughly with flour so that no lumps form.
2. Place the resulting mixture in a container on the fire, wait until it boils, but do not boil. When the mixture acquires a thick consistency and turns white, constantly stir the wallpaper paste until it has a uniform structure and is free of clots.
3. Now you can send glycerin and ethyl alcohol. It is very important to stir the mixture all the time so that it becomes as thick as possible. It is necessary to stir for 10 minutes so that you do not think that two stirrings will be enough.
4. When the homemade glue has cooled, it can be used for gluing canvases.

Dextrin-based product

If you need to glue peeling wallpaper, then the presented composition will be ideal option. It is very easy to make at home, spending a minimum of time and money. The glue is based on dextrin, which can also be made at home, rather than looking for it in the store. It can be prepared from starch.

The base element in this recipe is starch, not flour.

This ingredient is taken in the required volume, and then placed in a heat-resistant container, which is then placed in a slightly heated oven. Bake the starch at a temperature of 160 degrees for half an hour. Due to the influence of hot air, starch begins to disintegrate and turns into dextrin. After this, you can make homemade glue.

Required components:

• dry dextrin - 60 g;
• water - 4-5 spoons;
• glycerin - 1 spoon.

To get glue, you need to mix dextrin and water. After setting it on fire, heat it slightly so that the powder dissolves thoroughly, stirring all the time. After this, you can add glycerin. That's all, the prepared composition can be used for gluing paper sheets.

Moisture-resistant composition

When you are going to glue wallpaper in a room where there are increased level humidity. If you glue wallpaper in the bathroom, you don’t have to worry that it will come off after a while, since this glue is highly moisture resistant.

Granular wood glue

To get it, you need to take regular wood glue and put it in water until swelling occurs. Now you need to pour it into a bowl with linseed oil and wait until the mass becomes gelatinous.

It’s easy to make homemade glue even at home. In addition to the fact that the composition is of high quality, it does not require special effort And Money. All the components used can be found at home. Also, a homemade product is considered absolutely harmless, because it contains only natural ingredients. If you use the recipes presented, you will be pleasantly pleased with the results.

Industrial glue does not always satisfy the consumer, and sometimes force majeure circumstances arise when something needs to be glued, but there is nothing suitable at home. Self-prepared adhesives will help out.

PVA glue at home - an affordable recipe

When there is an urgent need to glue parts together, but there is nothing at hand, you can make glue yourself. There are many recipes that reveal the secrets of their manufacture. Most do not require any special components; all are available and commercially available. By adhering to the recipe and technology, you can be confident in the quality of the ingredients. (PVA) is one of the most popular due to its versatility and wide range of consumption. It is used to join paper, cardboard, leather, wood, fabrics, glass, and porcelain. In everyday life, it has proven itself well as wallpaper glue and a composition for furniture repair. PVA is widely used in construction as an additive to increase adhesion, gluing linoleum and tiles.

It is quite possible to make PVA at home; of course, the glue will not fully meet the industrial recipe, but the characteristics of such a home-made composition are similar to those of a store-bought one. We buy ingredients: distilled water, gelatin used in photography, glycerin, wheat flour, ethyl alcohol. If we buy glycerin and alcohol at the pharmacy, then photo gelatin can only be found in specialized photography stores. Distilled water is sold in auto stores.

First, soak 5 grams of gelatin in a small amount of water for a day so that it swells well. Immediately before preparing the PVA, stir cold water 100 grams of flour until smooth and without lumps. Heat a liter of water in a water bath, gradually pouring in a solution of gelatin and flour. Stirring constantly, bring to a boil and turn off the heat. Add 4 grams of glycerin and 20 ml of alcohol, mix everything for 5-10 minutes to obtain a thick, homogeneous mass. Cooled PVA is ready for use. Despite its versatility, the capabilities of PVA are still limited to certain materials. But there are alternatives, including homemade, which we will discuss below.

Wallpaper paste made from flour - how to prepare it correctly?

The variety of wallpaper adhesives and their recipes are amazing. Each package indicates what adhesive is made from for different types of wallpaper. It is unlikely that you will be able to prepare this at home, but there is a recipe for flour paste - old and proven over the years.

Preparing the paste is simple and quick: you need flour or starch and water. For two or three rolls of wallpaper, one liter is enough. For this amount we take 6 tablespoons of starch or flour. We put a liter of water on the fire, and until it boils, in a small volume cold water separate the flour. Stir thoroughly so that there are not the slightest lumps. The thickness of the mixture should resemble sour cream. Slowly pour it into boiling water, stirring constantly. Let it boil again and leave to cool.

The finished composition should resemble thick jelly in consistency. The use of paste for gluing walls with wallpaper ensures that they will adhere perfectly to a wall made of any material. It is also capable of joining any kind of paper and cardboard. The advantages are undeniable: very cheap, environmentally friendly. The quality of a properly prepared paste is superior to some industrial samples.

How to join wooden materials - a simple solution

Wood glue is traditionally used for gluing wood, which is considered the best for these purposes. It has some features that do not allow it to be stored in finished form for a long time. In a liquid state, after a short time it turns into gelatin and is covered with mold. More long time A gelatinous mass can be stored, from which pieces are cut off for the subsequent preparation of casein glue. There are several cooking methods.

According to the first method, we grind the most common wood glue and soak it in water until it swells completely. Ready mix soft, reminiscent of jelly. We melt this mass in a water bath in a container called a glue bottle. If it is not there, we use any utensils, even tin can. The fire should be very low, make sure that the mass does not burn. Burnt glue turns yellow and is weaker than properly prepared glue.

Constantly stir the gelatinous mass wooden stick until it becomes liquid. Add vodka to this liquid at the rate of one liter per 760 grams. You will need powdered alum - 12 grams per 100 grams of glue. This recipe allows you to prepare the most durable wood glue with water-repellent properties.

It’s easier to make wood glue using the second method. In a glass bottle, bring wood glue to a boil in the same ratio with water. When the mixture begins to cool and becomes thicker, pour it into a porcelain mortar and grind with a pestle until the mass becomes gelatinous. Place the mixture on a plate, wait until it cools, and cut into smaller pieces. If necessary, dissolve the piece in water 1:1 and vodka, with which we take half the mass of the workpiece. Boil the mixture and cool.

Another easy way. We take equal parts of wood glue, 9% vinegar and vodka. First, boil the vinegar and glue in a water bath until the mixture is completely dissolved. Stirring constantly, add vodka. According to another recipe, we heat equal parts of glue and water in a water bath until the mixture becomes thick. Add glycerin equal in mass to the glue and continue heating until the water has completely evaporated. Dry the finished mixture and, if necessary, dilute it with water in equal proportions.

The possibilities of wood glue – did you know about it?

The capabilities of wood glue are not limited to just gluing wooden products, they are much wider. Based on it, you can prepare many adhesive compositions for various purposes. We will talk about syndeticone below, but for now let’s focus on other recipes.

It turns out that you can glue wood with metal, stone, glass with it, you just need to prepare the adhesive paste. Wood ash sift through a fine sieve and add to hot wood glue. To restore book bindings or create new ones, we also use wood glue to which we add glycerin (by weight, 1 part glycerin for 20 parts of glue). You can make waterproof glue by adding 1 part of natural drying oil to 4 parts of hot wood glue.

How to isolate casein from cottage cheese and milk?

This is a universal household product repair work used not only for joining wood to wood, but also in combination with other materials: cardboard, plastic, fabric, leather. It is also capable of firmly gluing earthenware, plastic, and foam. Proper work with such glue guarantees that the connection will be strong and durable.

On sale casein is heavy White powder, and to make glue from it, you only need water. But to isolate casein from ordinary cow's milk You can do it at home. The method is little known, but interesting. In addition to milk, vinegar is used, which separates it into liquid and solid components. With the addition of soda it is formed alkaline environment, which dissolves casein. You should be aware that the resulting product is not food grade.

To make casein glue, we perform simple operations with our own hands:

1. 1. In any container ( better frying pan) heat the milk, but do not bring it to a boil. Add 9 teaspoons of vinegar per liter of hot milk and heat, stirring until lumps of curd and whey form.
2. 2. Through a sieve, separate the solid part from the liquid and put it back on the frying pan. Add a little water and 3 tablespoons of soda, heat until bubbles appear on the surface.
3. 3. Mix the mass well and leave to cool. It can be used as glue.

You can also isolate casein from cottage cheese by defatting it. To do this, soak it in an alkaline solution for 20 minutes. Prepare an alkaline solution from two spoons baking soda, dissolved in water. Then rinse the cottage cheese thoroughly running water, squeeze and dry. Once dry it will become hard. We prepare a powder from it, which is casein.

Prepare glue from dry casein powder. We measure required amount powder and twice more water. Pour the powder into a flat-bottomed bowl, add water little by little, without stopping stirring. The quality of the desired product depends on the quality of mixing. You can use a regular mixer, work will go faster, and manually it will take at least half an hour. The result will be a thick mass that must be used immediately, otherwise in about two hours it will harden and become unusable.

How to create hot melt adhesive - nothing could be easier

Perhaps the best invention that allows you to stick everything to everything is hot or thermoplastic glue. It has one feature that fundamentally distinguishes it from its counterparts - it passes from solid to liquid and back without losing its qualities and without changing volume. Industrially produced as rods different colors. To use it, you will need special equipment - a heat gun.

Do hot glue at home you can use ordinary plastic bottle. To do this, we cut strips of the required length, twice as wide as the parts to be glued. We bend the strip in half along its length and place it on one of the surfaces to be glued. Will need construction hair dryer, which we use to heat the plastic. When it softens, apply another part and wait until it hardens completely. Cut off excess glue with a knife.

The advantage of homemade hot glue is that it can be reused. If gluing does not work the first time, heat up the joint and repeat the process. If the parts are connected by mistake, it’s okay: we heat up and separate the parts, remove the remaining glue. The parts glued in this way are held tightly. Industrial hot melt adhesive is disposable - only rods are used for the hot melt gun.

Homemade superglue - a universal assistant for the master

You can get glue with the characteristics of a universal one using carpentry glue. Take 400 ml of water and dissolve half a glass of sugar, mix in slaked lime - 30 grams. Heat for an hour, stirring all the time. We get a clear solution, drain it and add 120 grams of wood glue, cut into pieces. We wait for the moment of complete swelling and cook as usual until a homogeneous substance is obtained.

You can make superglue using another recipe. Very affordable way, which does not require large expenditures - based on acetone. We use pieces of linoleum or plastic as filler. Place in small pieces in a container, which can then be tightly closed. Fill the raw material with double the amount of acetone, seal the container hermetically and place it in a dark place. We watch when everything dissolves and use it to join wood, metal, porcelain and other things.

Minor household repairs - using improvised means

Occasionally you have to glue things together that are made from rare materials, or repair something. Some tips will help you get out of this difficult situation. If you need to connect organic glass (plexiglass), we make an adhesive composition from it. We prepare a small amount of small plexiglass sawdust and fill the bottle with it. We dilute acetone and amyl acetate equally and fill the plexiglass sawdust with this solvent. Place in a warm place and wait for complete dissolution. If we use only acetone, the plexiglass will not completely dissolve, but the composition is suitable for work.

In everyday life there is often a need to glue glass, porcelain and earthenware products. Take liquid glass and dissolve casein in it - the repair agent is ready. Particularly good for porcelain and earthenware gypsum mortar on egg whites. It thickens almost instantly, we work quickly and carefully. We are preparing another composition for earthenware and porcelain. Whisk the egg whites and place in the refrigerator for 24 hours. Separate the settled protein and thoroughly grind it with quicklime until a dough is obtained. Glue quickly, spreading with a thin layer.

You can glue linoleum and tiles with unusual instant glue. We crumble the foam and fill it with the place that needs to be glued. Spray the foam with acetone, which immediately begins to melt, and press the parts to be glued. This is a very convenient means for gluing soles. We push the foam balls into the place that needs repair, drip acetone and press.

To help your hobby - original ideas for adhesives

If you are interested in origami, paper appliqué, or quilling, then you undoubtedly know that the best glue for such activities is dextrin-based. It is not at all necessary to search for it in stores. Dextrin can be easily prepared at home from starch. We take the required amount, pour it into a heat-resistant container and place it in a slightly heated electrical cabinet. Then we gradually increase the temperature until it reaches 160°. We maintain this temperature for an hour and a half, during which time the starch will be converted into dextrin.

Let's start making glue. You will need three tablespoons of dry dextrin, no more than five tablespoons of water and a spoonful of glycerin. Mix dextrin powder with water and heat slightly until dry matter completely dissolved. Don't forget to stir constantly. TO ready-made composition add glycerin.

A popular hobby among women is making flowers from various fabrics. Flowers with petals glued to each other are especially elegant and spectacular. The simplest glue is made from three tablespoons of flour and a glass of water. To cook the glue, first dilute the wheat flour with a small amount of cold water, and then gradually pour it into a glass of boiling water and bring to a boil.

According to the second method, mix thoroughly in a glass of water so that there are no lumps, add a tablespoon of wheat flour, starch and sugar and bring to a boil. Good glue for making fabric flowers, it is obtained from a gelatin packet. Soak the gelatin for 12 hours in a third of a glass of water. After the allotted time, stir gelatin, two tablespoons of flour, and one tablespoon of sugar into ⅔ glass of water. Bring to a boil, cool, store in an airtight container in the refrigerator.

Homemade baked goods with decorations that look like various figures, flowers made from food mastic is not only a hobby, but also a small business. To ensure that the entire decor adheres securely to the surface of the baked goods and retains its shape, food grade glue is used. People buy it often without knowing that glue can be made at home. We use starch, from four tablespoons of which we cook jelly in a glass of water and keep it warm until it becomes thick and viscous. According to the second method, boil a glass of sugar in a glass of water. You should get a slightly undercooked toffee caramel, which is food glue.

Probably everyone knows how to properly glue parts (surfaces) together. After all, on any tube of glue everything is written in detail. Now we will look at several options on how to make very strong glue at home. For many, such opportunities will be a real discovery.

First, let's repeat the general rules for gluing objects:

The surfaces to be bonded must be well cleaned of various contaminants, grease and old glue.

For stronger bonding, the surface must be rough; this can be achieved using a file or sandpaper.

Why must the glue layer be thin? A thick layer of glue “creates” conditions for the emergence of forces that “expand” the adhesive film. Consequently, with a thinner layer, a stronger bond is obtained.

It is necessary to apply a weight to the adhesive seam, use the force of your hands, or tighten it with ropes.

So, we know how to properly glue the sole of your favorite slipper, or glue two halves of a cup together. But none of us plans to break or tear anything, and specially, “just in case,” does not keep universal glue at home. Or, as always, it ended at the wrong time.

What can replace factory glue?

1. Unusual adhesive for linoleum and tiles can be made from polystyrene foam and acetone.

This is done very simply: crumble the foam into the place that needs repair and spray it with acetone. As soon as the foam begins to melt, press down on the surfaces to be glued.
** This unusual product is very convenient for gluing the sole. In the same way, pour foam into the hole, drop 10-15 drops of acetone, wait a little and press.

2. Glue the glass and plastic products Ordinary garlic will help you. You just need to grease two surfaces with a cut garlic clove.

3. If there is chalk and “liquid glass” in the house, then you can make fireproof putty. It will also help you glue porcelain and glass.

4. It fell off tile? A mixture of tooth powder and ordinary silicate glue (stationery glue, for gluing paper) will help correct the situation. Craftsmen say it works very strong glue.

5. Cut the remaining linoleum into small pieces (without a fabric base), put it in a jar and fill it with acetone. After 10 hours you will have a permanent glue ready. If you add chalk 1:1 to it, you get mastic.

6. If you have wood glue around the house, you can make it more waterproof by adding it to hot water. glue solution drying oil (25 g per 100 g of dry glue).

Use these tips if you have an extra piece of linoleum or foam on hand.

In my house, of all the above, I only found garlic and acetone, and also factory-made super glue, bought once “just in case.”

In this article:

Glue is a substance that is used in household and in almost all areas of production. The reason for such popularity of adhesives is the ability to connect objects that are different in shape, composition and not the same in size. Modern views adhesives provide high reliability connections and aesthetics.

Due to the huge scope of use of adhesives in the household, there are very often cases when glue is urgently needed, but it is not available. And then many people wonder how to make glue at home?

So let's look at how to make different kinds adhesives at home.

How to make PVA glue at home

In order to prepare PVA glue with your own hands, you need to select the following ingredients:

• glycerin – 4 grams;
• wheat flour – 100 grams;
• distilled water – 1 liter;
• ethyl alcohol – 20 ml;
• photographic gelatin – 5 grams.

Some of these raw materials are always available at home, and the rest you can buy at the pharmacy. Before preparing the glue, you need to soak the gelatin in plain water a day before.

When the gelatin has already infused, it is necessary to build water bath from kitchen utensils. Place all raw ingredients, not including alcohol and glycerin, in a container and cook in a water bath.

Stir the resulting mixture constantly and wait until it reaches the desired consistency (thick).

When the mass has become thick, you can add ethyl alcohol and glycerin to it. Next, you need to thoroughly stir the mass until there are no inhomogeneities in it. After the mass has become homogeneous, you can stop the process of preparing the glue. You can use homemade PVA glue as soon as it cools down.

DIY wood glue

Quite often in the household it is necessary to glue wood, cardboard or paper. And then it is best to prepare wood glue at home. To prepare it you need a tile of wood glue. Before directly preparing the glue, you need to break the tiles into small pieces and place them in a container. Next, you need to fill the pieces of tile with cold water, wait 10-12 hours until the glue absorbs the water and forms a gelatinous mass.

After this, the container with glue must be placed in a water bath and stirred constantly so that it does not burn. If you need wood glue of a thin consistency, then it would be advisable to add hot water to the mixture. There is no need to bring the glue to a boil; when there are no lumps in it, it means it is ready.

If you need to glue the leather together with wood glue, then you need to add glycerin to the prepared mass. Calculation: 1 teaspoon per 0.5 liter of glue.

Features of preparing tile adhesive at home

If you have already purchased facing tiles and want to work, then you need to prepare tile adhesive with your own hands. As a rule, the adhesive mixture is prepared from cement and sand, water and PVA glue. Sand acts as a filler and should be small sizes, the maximum grain diameter is no more than 2 millimeters.

The ratio of cement and sand should be 1:3. In this case, the measure is not the weight of the materials, but their volume. For example, 2 buckets of cement require 6 buckets of sand.

It must be remembered that tile adhesive hardens quickly and must be prepared immediately before installation. facing tiles. The tile adhesive solution can be used for no more than three hours.

Making glue at home is carried out in the following sequence of actions:

• Cement and sand are thoroughly mixed.
• Then water is added to the resulting mixture, having previously dissolved PVA glue in it. A bucket of tile adhesive requires 0.5 kg of adhesive. If the facing work will be carried out in a room with high humidity, for example in the bathroom, then the volume of glue can increase and reach a maximum of 3 kg.
• Then the tile adhesive is thoroughly mixed, its consistency should be thick. If the mass has become homogeneous, it means that the glue is ready for use.

The bonding strength of homemade tile adhesive is quite high, but is inferior to industrial analogues.

How to make casein glue at home

If casein powder is available

According to its properties casein glue similar to carpenter's adhesive, but it is not afraid of moisture. Making casein glue with your own hands is quite simple. To prepare it, you need a flat container, casein powder, borax and water. First, casein powder is poured with water and allowed to brew for three hours. Then the borax must be dissolved in hot water in a ratio of 1:7. The resulting solution is added to casein. This mixture is heated in a water bath to 70 ° C and stirred constantly. The glue can be used 40 minutes after it is removed from the water bath.

If you do not have casein powder, then you can prepare it yourself.

How to make casein glue from milk

To prepare casein powder, you need skim milk. The milk is placed in a warm place to sour and then filtered using cotton wool or blotting paper. Next, the casein remaining on the paper is washed in water and boiled. Finally, the casein must be spread out on paper and dried at room temperature.

After preparing the casein powder, you can begin to produce glue. To prepare the glue you need borax, water and casein powder in a ratio of 1:4:10. Next, mix the raw ingredients, but first add half the water. Then add the remaining water to the resulting thick consistency and mix everything thoroughly. Casein glue must be used immediately; it hardens after 3 hours.

Features of preparing wood glue

Making your own wood glue is very easy. The composition of this glue includes: flour, water, aluminum alum, rosin in a ratio of 40:10:1.5:3. All raw materials are filled with water and mixed thoroughly. Then the mixture is placed on low heat and heated. As soon as the glue begins to thicken, it is removed from the heat.

Use wood glue immediately before it hardens.

How to make waterproof glue

Quite often, households need glue that is not afraid of dampness. This type of glue is usually called waterproof. Waterproof glue is used for tiling work in kitchens and bathrooms. This type of glue can be purchased ready-made, or you can prepare it yourself at home.

There are several ways to produce glue at home:

1. In the first method of preparing glue, you need cottage cheese or curdled milk, slaked lime. These two components are mixed until a thick, homogeneous mass is obtained. After this, the glue is ready for use, but you must remember that after applying the substance to the surfaces, you need to carefully compress and dry them.

2. Adhering to the second method of making glue, you need to purchase 100 grams of high-quality wood glue, 35 grams of drying oil. Wood glue is placed in a glass and simmered over low heat until it becomes liquid. Then add drying oil and stir the mixture thoroughly. This glue must always be warmed before use. This DIY hot glue perfectly connects wooden surfaces, used when laying tiles, it is not afraid of either cold or hot water.

Knowing how to prepare various types of adhesives at home, you can always complete all tasks efficiently and on time. household work, creating a cozy and pleasant atmosphere.
