How to make strong glue at home. How to make glue at home - everything ingenious is simple

Homemade glue can be prepared by yourself at home. How to prepare the glue yourself and how to use it is described on this page of the site.

WOOD GLUE

Tiles of carpentry glue are broken into pieces, lowered into the glue pot and poured cold water so that it slightly covers the glue. When the glue swells (after 10-12 hours), the glue maker is put on a small fire, where it is kept until the glue dissolves. It should be used while it is hot.

Adhesive paste

For bonding to metal, glass, stone, etc. In hot wood glue add finely sifted wood ash to make a thick paste.

Bookbinding glue

Glycerin is added to the melted wood glue (1 part by weight of glycerin to 20 parts by weight of glue).

Syndeticon

The composition of this glue: sugar 120 grams, slaked lime 30 grams, wood glue 120 grams and water 400 cubic centimeters. First, sugar is dissolved, then lime is added and heated, stirring, for an hour. The clear solution is drained and pieces of wood glue are added to it. When the glue swells, it is boiled as usual until the glue is completely dissolved. Syndeticone is a universal adhesive.

Waterproof adhesive

Natural drying oil is added to hot carpentry glue or linseed oil(1 part drying oil or oil to 4 parts glue).

PASTE

Starch: Potato flour (starch) is poured with a small amount of water and thoroughly stirred until a creamy state. Steep boiling water is poured into the resulting solution in a thin stream, continuously stirring the solution so that there are no lumps. As soon as the paste becomes transparent and gelatinous, it can be used.

Flour: Sifted wheat or rye flour is poured into boiling water, and then, stirring, heated over low heat until the flour is brewed.

Dextrin glue

Dry potato starch is heated on an iron sheet to 400°C. The resulting brown translucent lumps are broken into powder. Glue preparation: 10 grams of this powder is carefully diluted into 20 -25 cubic centimeters cold water. You can also add 2 grams of sugar. Glue is used mainly for gluing paper.

GLUE ARABIC GUM

Gum arabic is made from a gum (resin) that some plants secrete. However, a completely satisfactory glue can be obtained using the resin of cherry, plum, apricot trees, as well as the resin secreted by white locust. Pieces of this resin are cleaned of bark and dirt, dried and ground into powder, which is stored in a closed vial. As needed right amount powder is dissolved in warm water and the glue is ready to use. gum arabic - best glue for paper.

CASEIN GLUE

Casein glue is used for gluing various materials, including faience, plastic, etc. Casein glue is more moisture resistant than wood glue. Casein is usually sold in powder form, but you can easily make your own.

Obtaining pure casein: Skimmed milk is put in warm place to make it sour. It is then filtered through blotting paper.

Casein (protein substance of milk) remains on paper. It is washed in soft water, then, tied in a cloth, boiled in water to remove fat. After that, the casein is laid out on blotting paper and dried at room temperature. Glue preparation. Ten parts of casein and one part of borax are kneaded in two parts of water until a dough is obtained, then two more parts of water are added. The resulting adhesive is usable for two to three hours, after which it hardens. Casein glue can be prepared by adding ammonia dropwise to the curd until a gelatinous transparent mass is obtained. This mass is used to lubricate the parts to be glued. For greater strength, glue-lubricated surfaces are allowed to dry, then coated thin layer lime paste and after that the parts to be glued are connected.

A few drops of formalin or a solution of aluminum alum are added to the finished casein glue to obtain a waterproof glue.

CELLULOID ADHESIVE

Celluloid glue can be used to glue a wide variety of materials - wood, leather, fabrics, plastics, etc. The glue dries quickly and is not afraid of moisture at all. For the preparation of glue use unusable film. It is washed in hot water from the emulsion and cut into small pieces. These pieces are placed in a vial and filled with acetone or amyl acetate (pear essence). For one part of celluloid take 2-3 parts of acetone. The vial is shaken from time to time. When the film is completely dissolved, the glue is ready for use.

ADHESIVE FOR GLUING ORGANIC GLASS (PLEXI GLASS)

Small sawdust of organic glass is placed in a vial and filled with a solvent composed of equal parts of acetone and amyl acetate. After pouring the solvent, the vial is placed for several days in a warm place. When the organic glass dissolves, the glue is ready for use.

Acetone or pear essence alone can also be used as a solvent, while the organic glass will not completely dissolve, but the resulting solution can still be glued. Organic glass before gluing is heated to 20°C.

RUBBER GLUE

Glue for rubber products can be made in the following way. A piece of good soft rubber (crude rubber) is crushed into small pieces, which are insisted for several days on clean, light so-called 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 used for gluing. The surfaces to be joined must be free of all dirt and grease.

Another recipe for glue for galoshes: 13 parts of gutta-percha and 25 parts of rubber are dissolved in 100 parts of carbon disulfide. 7-8 parts of bovine glue are added to the resulting solution and mixed. If the surfaces to be glued are cleaned (with a knife or sandpaper), then it is enough to put a thin layer of this glue so that the connection is very strong. The glue hardens completely after 1-2 days.

GLUE FOR STICKING BLOTH OR LEATHER ON TABLES

Glue composition: Wheat flour - 10 parts, alum - 0.2 parts, water - 410 parts. wheat flour is kneaded in cold water until a slurry without lumps is formed.

The rest of the water is heated to a boil and alum is dissolved in it. The slurry is added to the alum solution, stirred and the mixture is boiled until a translucent mass is formed.

ADHESIVE FOR TISSUE PAPER

The dextrin is mixed with a small amount of water and such an amount of denatured alcohol is added to make a syrupy liquid. This adhesive does not seep through the paper.

ADHESIVE FOR GLASS, PORCELAIN AND FAIENCE

To get a mass for gluing glass, you need to melt 50 grams of light shellac with 25 grams of turpentine over low heat. The mixture is cooled slightly and divided into small tiles. When used, the mass is warmed and carefully connected. Excess mass is carefully removed. When gluing glass, gelatin is also used, to which a small amount of an aqueous solution of potassium dichromate is added. This glue under the influence of light becomes completely insoluble even in hot water.

casein dissolved in liquid glass, is also suitable for this purpose.

Porcelain can be glued with the same compounds as glass. For repairing dishes, gypsum cement mixed with egg white is especially good. This cement hardens very quickly, and therefore must be handled with great care.

You can get glue for porcelain and faience in the following way: Knock egg whites into foam and put them in a cool place for a day. After that, the settled protein should be separated and carefully ground with quicklime powder, adding it gradually in such an amount that a pasty mass is obtained. This glue is applied to the parts to be glued in a thin layer. The bonding process must be done as soon as possible so that the glue does not have time to dry. To glue parts of porcelain and glass objects, you can use the following lubricant: take washed glass flour (crushed glass) -1 part, add river sand(seeded) -2 parts and liquid glass -6 parts. This putty cements the parts to be glued very firmly. In structure, it is somewhat rough, so it is used for gluing large objects.

HERE IS ANOTHER putty, which differs from the previous ones in a smaller structure, is also used for gluing large objects. They take burnt lime (quicklime) -1 part, chalk (ground) - 10 parts and liquid glass 2.5 parts. According to both recipes, the putty is prepared before use, as it quickly hardens. There is a particularly hard putty for gluing medium-sized objects made of glass and porcelain. It can be prepared as follows: burnt sculptural or medical plaster is taken and placed for one day in a saturated solution of alum. Then it is dried and again calcined and crushed. Gypsum treated in this way, in combination with water, turns into a very solid mass. The ratio of gypsum and water should be such that a liquid mass of cream consistency is obtained.

GLUE FOR GLUING AMBER PRODUCTS

Amber products can be glued as follows. The surfaces to be joined are washed with an aqueous solution of caustic potassium, slightly heated and tightly compressed. The parts to be glued can also be lubricated with a thin layer of boiled linseed oil, after which the seam should be carefully heated over a flame. charcoal. In this case, the parts to be joined must be strongly compressed with a clamp or tied with wire. An adhesive consisting of a solution of solid copal in ether is also recommended.

ADHESIVE FOR GLUING IVORY PRODUCTS

Ivory is glued together with a paste of slaked lime and raw egg white. For this purpose, you can also use a solution of albumin in water. The parts to be glued should be tightly compressed and left to dry in a cool place for at least a day. Small items from Ivory glued together with an alloy of equal parts of wax, rosin and turpentine.

This composition is not particularly durable, but it is very convenient to use.

LEATHER GLUE

The skin is glued with a solution of pure rubber in carbon disulfide. Warm up the parts to be glued and carefully rub the glue in place of the future seam. It is recommended to add a small amount of turpentine to the resulting solution. Leather glue can also be prepared as follows: a good light wood glue is soaked in water for a day and then slowly melted over a fire with a little water. After that, tannin is added to the liquid mass, which makes it look like sticky threads. Gluing is done with this sticky mass, and the skin must first be cleaned (washed with gasoline) and roughened with glass paper (skins).

ADHESIVE FOR GLUING MARBLE PRODUCTS

Marble can be glued with the following composition: four parts of gypsum and one part of gum arabic in powder are thoroughly mixed. Then a strong solution of borax in cold water is added until a dough is obtained. The parts to be joined are smeared with this putty, tightly compressed and left to dry in a cool, dry place for 5-6 days. Another way of gluing marble: two parts of wax and one part of rubber are mixed with two parts of marble crushed into a fine powder and heated over a fire. Marble must be completely dry when gluing. External cracks are additionally smeared with alabaster, pounded into a gruel with glue water. If the marble is gray, then slate is taken instead of alabaster, and red and dark marble is smeared with ocher. Finally, the entire surface is polished with very fine pumice or tripoli.

ADHESIVE FOR GLUING GYPSUM PRODUCTS

Gluing gypsum products should be done using syndeticone or thick wood glue. In both cases, you need to make sure that the glue does not squeeze out of the seam outward, as this results in a black line that spoils the look of the thing. The seam should be covered with plaster from the outside.

GLUE FOR GLUING BROKEN TOOLS

A broken donkey can be glued together, even if it has broken into small pieces. First of all, it is necessary to carefully clean and remove all oil particles from the fracture points by heating the pieces on a hot stove. After that, all particles that should be in contact are carefully sprinkled with shellac and heated again until the shellac melts and fills the pores. Heating must be done on a smooth metal board, and the flame must not touch the pieces, otherwise they may crack elsewhere. For this reason, they should not be heated too much. When the shellac is melted, the pieces are put together, pressed against each other and left in the clamp until they cool. The pieces connected in this way are so firmly glued together that they will not yield to a single stone.

GLUING THE PIANO KEYS

The bone plates lagging behind the keys are glued as follows. Mix white zinc oxide with ordinary wood glue, then process with a file or sandpaper surfaces of both the wooden key and the bone plate, lubricate the key with the specified mixture and leave it for 5-10 minutes. After that, a plate is placed on the key and tied with a cord. After 3-4 hours, the glue will dry out and the excess that has come out at the edges can be removed with a file or sandpaper.

GLUING MICA

Mica is glued together with a liquid solution of gelatin. If the bonding must be particularly strong, then chromic alum is added to the gelatin.

UNIVERSAL CEMENT

Universal cement (Chinese) is prepared as follows: prepare a mixture of 54 parts of slaked lime powder, 5 parts of finely ground alum and 40 parts of fresh, well beaten bovine blood. All the above substances should be mixed as thoroughly as possible to obtain a homogeneous mass of the desired density, depending on the intended use. In its thick form, this cement can be used to bond stone, faience, porcelain, etc. In a thicker form, it is used to coat various kinds of objects to make them waterproof.

UNIVERSAL GLUE BF-2

It is a thick, clear, light-colored liquid. yellow color, which is used for gluing vases, figurines, bas-reliefs, antiques made of earthenware, glass, plastic, wood and metals, as well as for repairing metal products: buckets, tanks, etc. Not recommended for gluing dishes in which food is cooked. When gluing, make sure that water does not get into the glue. The surfaces of the products to be glued are thoroughly cleaned from dirt, dust, rust and traces of grease. Metal objects are treated with sandpaper and washed with gasoline or other means, non-metal - washed hot water with soda or gasoline. The places to be glued are thoroughly dried after their cleaning. Depending on the type of damage, the repair is carried out as follows: the edges of the product for butt gluing are smeared with a thin layer of glue using a wooden stick or brush and dried in air until the glue no longer sticks to the finger. Then apply the second thick layer glue and dry slightly. The parts to be glued are tightly connected by tying with a rope or bandage.

glued small items placed in a pot or metal jar, filled with water and put on fire. The water is brought to a boil, which should last at least three hours, after which the pan is removed from the heat, cooled in air and the products are removed. You can also heat the products in ovens or stoves at a temperature of 120-150 ° C for 1 hour, or over an electric stove. Holes in products, such as metal, are sealed as follows from suitable material(tinplate, aluminum, copper, etc.) cut out a patch, the dimensions of which should be more holes 0.5-1 cm.

Apply a patch to the hole and glue the product. Then water is poured inside the dish so that it reaches the bottom edge of the patch and does not touch it. Putting the product on an electric, gas stove or kerosene, boil the water for at least two hours, then remove it from the heat and cool it in air. If a patch is applied to the bottom of a bucket, basin, etc., they are heated over a fire for one to two hours. When gluing figurines, ashtrays, antiques, large vases etc., where high bonding strength is not required, it can be limited to exposure at room temperature for four days.

GLUE BF-6

This adhesive is used to repair clothes, linens, carpets, etc. It is a thick, clear yellow or red liquid. The places of products to be glued are preliminarily cleaned of dust with a brush, moistened with warm water and squeezed well. After straightening the edges of the wetted areas of the fabric, two layers of glue are applied to them and air-dried after applying each layer until the glue no longer sticks to the finger. Then the objects to be glued are connected and pressed on with a hot iron (carefully). The iron is pressed through the damp cloth for 2-3 seconds at intervals of 10-15 seconds until the surface to be bonded is dry. After cooling to room temperature, the product is ready for use.

HOMEMADE GLEEVARKA

It is impossible to cook wood glue directly on fire, as it can burn. Therefore, it is cooked in special glue pots.

You can also make a glue cooker yourself from tin cans. Take one jar bigger and the other smaller. At the top of a large jar, several holes are made with a diameter of 5-6 millimeters. Iron staples are soldered to a small jar, with the help of which it is fixed on a large jar. Dry glue is soaked and placed in a small jar, and a large one is poured with water and heated. When the water boils, the glue will melt and you can use it.

Making PVA glue on your own without leaving your home is the topic of today's article.

About PVA glue, without exaggerating, we can say that it one of the best and most popular bonding materials. This glue is used for gluing paper, wallpaper, and some other surfaces.

Immediately I want to note that to prepare such glue yourself is not a difficult task.

If there is a situation in which you urgently need to glue something, while there is no time or opportunity to go to the store, then you should not be upset, you can cook PVA yourself. If you follow all the rules and tips, then the prepared glue will turn out to be no worse than the purchased one, and you will be able to save money.

Information about polyvinyl acetate

What is polyvinyl acetate? This is the well-known PVA glue. If we talk about the production of glue in industrial scale, it is made using special equipment. For its manufacture, it is necessary to mix the polyvinyl acetate dispersion and the filler. All this is mixed in a mortar mixer.

I want to say right away that there are enough types of this glue. The most common are: wallpaper glue, stationery glue, universal. At home, you can make an analogue of PVA glue, why an analogue, but because it will be problematic to make everything according to the recipe. But the analogue will not be worse than the original.

Recipe for making glue at home

There are several ways to prepare glue, but this one is the simplest and most common. Besides, everything necessary ingredients, apart from photographic gelatin, it is easy to buy at every pharmacy. True, this recipe will still need flour, of course, it cannot be purchased at the pharmacy, but any grocery store, as they say to help.

What ingredients are needed to make PVA glue?

• Distilled water. Such water will need about a liter and a half.
• Ethyl alcohol, it needs about 25 ml.
• a teaspoon of glycerin. This is approximately 5 gr.
• the same amount of photographic gelatin.
• And, of course, flour. ITS will go somewhere 100-110 grams.

Cooking: steps

1. First you need to soak the gelatin in warm ordinary water. for a day.
2. Then it needs dissolve with a steam bath.
3. Next, add water and flour to the gelatin.
4. The resulting mixture should be kept on fire until a consistency resembling thick cream.
5. While the mixture is on fire, it should be stirred without interruption. After obtaining the desired consistency, the mixture must be removed from the heat and allowed to cool slightly.
6. Then you need to add glycerin and alcohol, mix the resulting mixture so that there are no lumps.

After the mixture has completely cooled, it can be used to bond the same materials that PVA is commonly used for.

Glue storage rules

You can store self-made glue no more than six months.

It is perfectly stored at a temperature of 15-20 degrees above zero. If you leave it at room temperature, then nothing bad will happen. But if the temperature is low, that is, it has fallen below zero, then its shelf life in this case is no more than 30 days.

Where can PVA glue be used?

Application area this product is wide enough. With it, you can glue wallpaper, wood elements, fiberboard.

Joiner's glue is known to specialists in the repair of premises, it is appreciated for its affordable price and good adhesive properties.

It perfectly copes with the tasks and is used for joining wood, cardboard, plywood, hardboard. At the core is a protein substance that is responsible for bonding.

For production, different raw materials are used, adhesives can be obtained with different properties.

So, it occurs:

1. Bone carpenter's glue- it is made from bone waste and crushed bones. It is the most common.
2. Mezdrovy - made from tanning waste, leather residues and a layer of fiber, which is cut off during dressing of animal skins.
3. Fish - made from fish remains - heads, tails, entrails, scales. This type of glue is used during complex restoration work.
4. But the best is considered glue, from the horns. It has a special, light shade.

How to use wood glue

The main advantage of glue is high strength and if the tree is destroyed, adhesive layer usually remains intact. Disadvantages appear as bad smell, as well as the inconvenience of storage - in liquid form, it quickly becomes unusable, covered with mold.

Supplied either in the form of yellow-brown granules, or in the form of granules. Experts recommend paying attention to the color of the glue, the more transparent the shade of the granules, the better the final composition will be.

How to use:

1. To apply the glue, use a bast or bristle brush.
2. If gluing is carried out along the fibers of the tree, one layer is applied, two on the ends (the second only after the first has dried).
3. After a few minutes, until the composition dries, the objects are well compressed, then aligned with each other, the excess glue is removed, fixed with a bandage or twine, and left for several hours.

To increase resistance to mold, various antiseptics are added, such as ammonia, phenol or borax. And if you add chalk or ash, you get putty paste.

PVA glue joinery - characteristics

Wood glue based on PVA is sold already in ready-made there is no need to dilute in water. Ideal for hardwood as well as tropical woods. The resulting seam is not afraid of moisture, it is durable and transparent.

It is used everywhere, the rapid development of technology and the emergence of new offers on the market does not prevent it from being in demand.

Of the analogues, you can offer glue Moment carpentry, it is suitable for wood and plastic, quickly sets, very durable.

There are several ways to prepare wood glue with your own hands, but they are all based on the same principle - soaking and boiling in water.

To make wood glue with your own hands, the following ingredients are needed:

• yellow granules or hard glue tiles (the lighter the starting material, the better the composition will be),
• boiled water,
• tile,
• glue stick for cooking.

Wood glue recipe

1. Wrap the adhesive tiles in cloth and smash with a hammer.
2. Pour the crushed starting material with cold water so that it completely covers the dry glue. It should turn into a gelatinous mass. On average, it takes 4-12 hours. Water must be boiled.
3. Put the swollen composition in a water bath and cook for about 15 minutes at a temperature of 60-80C, stirring constantly. All lumps should dissolve, the mass will turn out homogeneous and liquid.
4. It is most convenient to cook glue in a special oilcloth of two vessels. into a vessel with big size water is poured, and into a smaller glue and placed inside a large one. The oilcloth is put on fire and the composition is boiled.
5. During cooking, hot water can be added to obtain the desired consistency. If studs or end joints are to be bonded, the compound should be slightly thicker than for plywood and other flat materials.
6. As soon as a film appears on the surface, the wood glue can be considered ready. The composition should flow from the stick not in drops, but in a continuous stream.

It is necessary to use glue until it has cooled down, and the oilcloth maintains a temperature of 30-70C for one and a half to two hours without additional heating. As the solution cools, it will lose its properties, and then it may even become moldy or begin to rot.

Option two

1. Another way, when glue and water are mixed in a one to one ratio,
2. Boil, and the resulting mass is ground,
3. Then spread on a plate and cut into pieces.
4. Such a preparation immediately before the start repair work dissolved in a mixture of water and vodka and boiled.
5. Can be added to water and glue during the preparation of the composition table vinegar, and when the powder is completely dissolved, add vodka.

Various components are added to the wood glue to give new properties, for example, linseed oil or drying oil mixed with dry powder will increase the resistance of the glue joint to moisture, and if you have to work with leather, glycerin is added.

The glue will retain its consistency at room temperature for no more than two hours, and then it will begin to thicken. Then you have to reheat it. In this regard, it is better to prepare the composition not in reserve, but only in the amount that is required.

The fact of the fortress of centuries-old buildings has always been surprising. But then there was no such diversity adhesive materials. For cooking, natural ingredients were used and their strength delights. What they are made of now, and how to make glue at home using improvised materials - there are many recommendations.

Cooking is used in some cases. One of the advantages is the preparation of harmless ingredients. It is necessary to solve such a problem when, in the midst of work, the adhesive has run out. What glue is made of, which will not yield to store-bought ones, will be discussed below.

How to make PVA glue

It is good to know PVA to get a quality product. It is necessary to observe the proportions, the technology of preparation. This composition is widely used in the manufacture of solutions that are used when facing tiles.

Components:

• water (distilled) - 950-1000 ml;
• alcohol (ethyl) - 20 ml;
• glycerin - 3.5 g;
• gelatin (photographic) - 4.5 g;
• flour - 100-120g.

Scheme:

1. Soak the gelatin in some liquid overnight.
2. Place the container in a water bath. Dissolve flour in liquid. Place gelatin solution in a container. There should be no lumps.
3. Wait for a full boil. The consistency of thick cream. For uniformity stir constantly.
4. Pour in glycerin, alcohol.
5. After complete cooling, the mass is ready for use.

Attention! Shelf life is about six months.

To use it as a primer, you can learn how to make PVA glue, and then use it for its intended purpose, but with a more liquid consistency.

Traditional paste recipe

Flour-based wallpaper glue at home has been known since childhood, when there was no such variety of products that store shelves now abound. When they used to carry out repairs, they knew how to make glue from flour and water, and. This environmentally friendly product popular even now. Everything that's needed:

• water - 950-1000 ml;
• flour - 160-170 g (6-7 tablespoons).

Scheme:

1. Prepare a container of the required size.
2. Dilute the main ingredient in a small amount of liquid. Mix thoroughly until smooth. The consistency of thick cream.
3. Boil water.
4. In a thin stream, stirring, in order to avoid the formation of lumps, pour in the flour solution.
5. Boil. Let cool. The consistency of the mixture is like that of jelly. If your fingers stick together when you open your hand, then it’s cooked correctly.

In terms of quality, such materials may be better than those produced industrially. Wallpaper glue at home has some disadvantages - afraid of water therefore it is undesirable to use in damp rooms.

You can enhance the properties by adding PVA or carpentry to it. When manufacturing, it is necessary to take into account the type of wallpaper. For heavier types, the consistency should be thicker.

It is advisable to strain the resulting composition through a sieve (gauze) to remove lumps, grains. The maximum quality is preserved for the first day, so you should not store a lot of it.

DIY wood glue

Optimum bonding agent wooden elements is a do-it-yourself welded wood glue. Accordingly, it is suitable for cardboard and paper. Some of the disadvantages of these compositions are Strong smell, a relatively short shelf life of the liquid composition. It should flow in a stream from the stick, and not drip. You need to use it before it completely cools down. The temperature of 30-60 degrees lasts for several hours. After cooling, it loses its properties.

Several methods have been developed for preparing wood glue with your own hands. The starting material is dry wood glue in tiles.

First way:

1. Crushed the main component and soak in liquid until swelling. The mass must be soft. Typically, this period is 6-10 hours.
2. Place in a bowl to melt.
3. Stir vigorously to avoid burning. Otherwise, the properties are lost.
4. Pour 970 ml of vodka into 750 ml of adhesive mixture.
5. Pour alum powder at the rate of 12 g per 100 g of the mixture.

Second way:

1. In equal parts, combine water and crushed starting material. Boil.
2. After cooling, pour into a container. When cool, cut into individual pieces. In this form, it is allowed to be stored.
3. Before use, for every 720-740 g, take 340-375 ml of vodka and 730 ml of water.
4. Bring the mixture to a boil.

Third way:

1. For one liter of liquid, take 1 kg of crushed starting component.
2. Heat the swollen material.
3. Pour in 960 ml of vinegar (9%) and 960 ml of vodka.
4. Mix thoroughly.

Fourth way:

1. By this recipe take water, dry matter in equal parts.
2. After swelling, heat with a water bath to a thick consistency.
3. Add glycerin, the same amount as used glue. Heat until the complete disappearance of water.
4. Pour into mold and dry. Such a preparation will be stored for a long time.
5. Before use, take the right amount, dilute with water in equal parts.

For purchase specific properties, linseed oil or drying oil is added to the traditional composition to increase the resistance of the seams to moisture. When working with leather, it is recommended to add glycerin.

casein glue

The casein composition is quite effective tool for gluing leather, wood elements and some other materials, including puzzles. Production consists of two stages:

1. You will need a regular homemade curd. It must be pre-degreased. It will take 30-35 g of soda for 1 liter of liquid. Soak the cottage cheese in this solution for a quarter of an hour. After rinse well, wring out, dry until completely hardened. Received lump grind into powder. This is how casein is obtained.
2. To obtain the material, you will need a part of the powder and two parts of water. Place the powder in a container, slowly pour in water. You will get a thick mass.

The more thoroughly mixed, the higher the quality! You can use a mixer, mix at low speed.

Glue based on dextrin

For paper needlework: quilling, appliqué, origami, a dextrin-based product is quite suitable. At the same time, there is no need to search for the main component in stores. It can be made from starch.

Components:

• dextrin - 3 tbsp. l.:
• water - 60-70 ml;
• glycerin - 1 tbsp. l.

Scheme:

1. Make dextrin from starch. Place the starch in the oven. Keep at 160 degrees about an hour and a half. When exposed to high temperatures, starch breaks down.
2. Mix dextrin with liquid, heat until completely dissolved.
3. Add glycerin.

Additional Options

There are many varieties of products prepared on the basis of improvised components.

Glue stick

Have you ever wondered what can be made from PVA glue at home? For the office, the most convenient is the glue stick. Making it is quite simple, having the necessary components at hand. For the case, both the packaging from the old one and the empty tube from the roll-on deodorant or other containers are suitable. The main thing is that she closed hermetically.

Scheme:

1. Finely cut laundry soap.
2. Mix two parts wood chips and one part water with water. Dissolve using a water bath.
3. Pour 3-4 tbsp. spoons of PVA glue. Cool down.
4. Put in the form.

If the mass is not very viscous, you can re-dissolve, add more soap chips.

Super glue

Many are interested in: how to make super glue at home, not in production conditions. You can get it using carpentry as a basis. Components:

• water - 450 ml;
• slaked lime - 35 g;
• sugar - ½ cup;
• glue (carpentry) - 125 g.

Scheme:

1. Dissolve sugar in liquid. Pour lime.
2. Heat for about an hour, stirring occasionally.
3. Glue cut into pieces. Place in solution. Wait for swelling.
4. Cook until a homogeneous mixture is obtained.

Super glue can be made at home and based on acetone. As a filler, pieces of linoleum or plastic are used. Action plan:

1. Prepare a container that can be tightly closed.
2. Place finely chopped pieces of linoleum or plastic in it.
3. Fill with double volume of acetone. Place in a dark place.
4. After complete dissolution, it can be used to bond metal, wood, porcelain.

Styrofoam Adhesive

With the increase in the cost of energy resources, it has become popular to insulate the facades of the house with foam. Making glue with your own hands is not difficult. For this, the use of carpentry is allowed, since acetone can melt the layers. Styrofoam glue can be made using cottage cheese and slaked lime. Mix in equal proportions until smooth. Since it hardens quickly, use quickly.

Styrofoam Adhesive

You can independently prepare a fairly high-quality foam material. Glue used for fastening metal, glass.

Scheme:

1. Place pieces of styrofoam in a container.
2. Pour in a small amount.
3. The splitting process will start immediately. Use liquid foam mass.
4. Apply to the surface, squeeze hard.
5. The hardening time is almost a day, but the period may vary, depending on air humidity and temperature.

Attention! Remove excess immediately, since after drying it will be problematic.

1. flour glue - universal remedy for wallpapering. But with a wide variety of wallpapers, it is necessary to take into account their density and know how to make high-quality material. If the wallpaper is dense and heavy, increase the amount of the main component. The thicker the consistency, the better it will hold. Depending on the wallpaper you will need from 300 to 500 g.
2. To cook, a smaller amount of the base is taken, about 100 g. It is recommended to add blue vitriol(1 g) so that it has antiseptic properties.
3. To strengthen the properties, you can pour in ethyl alcohol, denatured alcohol. Turpentine will also increase the stickiness, in a standard recipe you need to add 125 ml of turpentine.
4. The paste will gain ease of use by adding glycerin (4 g) or gelatin (5 g). The grip will get stronger.
5. In a paste, the main component can be replaced with starch, or a solution can be prepared by mixing with starch.

Necessary components: flour - a glass, starch - 35 g, water - 2.5 liters.

Action plan:

• dilute everything in cold water, mix thoroughly;
• boil water, slowly pour in the solution;
• boil the mass, let it cool.

Important! Use improvised means: natural, cheap. Repair and enjoy the result. After all, nothing is more pleasing to the eye than a job well done.

Useful video: making 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 finished glue for the most varied 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, poured into an oilcloth and poured with 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, hot water should be poured into the outer bowl of the oilcloth and put on a light fire. Depending on the desired density, you can add to the glue hot water. 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 continuously until you get a mass of such density as sour cream.
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.
Glue from dextrin is prepared as follows: 3 tablespoons of dextrin are kneaded in 4-5 tablespoons of cold water, heated while continuing to stir, 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 it into small pieces, put it in a vial with a ground stopper and pour it with 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 in a uniform, thin layer on the surfaces to be 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.
