Regardless of the achievements of modern chemistry and the emergence of a large number of adhesives for narrow and general purposes, the paste does not lose its position. Paste is a glue based on environmentally friendly and safe vegetable raw materials - flour or starch. The process of its preparation is simple, the raw materials are more than available. In this article, we will discuss how to make flour paste.

What is flour paste used for?

• Wallpaper pasting.
• Making papier-mâché.
• Binding and restoration work.
• AT children's creativity.

Flour paste for repair and painting work

Very high adhesion of the paste to various surfaces, including previously painted oil paint or treated with drying oil - the reason for its stable popularity. The disadvantage is low moisture resistance, which turns into an advantage during the next repair, because. wallpaper is easy to remove from the wall, eliminated with a variety of additives. The initial raw material is flour, best of all wheat flour of the first grade. Rye is used less often, because. glue based on it turns out to be dark and loses its versatility (although its adhesive properties are higher than those based on ground wheat grains).

PREPARATION (volume 5 l):

1. Sift 0.8-1.25 kg of flour (the quantity is determined by the thickness and quality of the wallpaper - the more expensive and thicker the wallpaper, the more you need to take).
2. Add a little water to it and mix thoroughly until the lumps disappear completely.
3. Pour the resulting thick solution into boiling water, stirring the mixture. For complete homogenization, the mixture can be heated over low heat without boiling.
4. To improve adhesion, it is necessary to add to the paste not a large number of wood glue from 70 to 150 g in dry matter. This glue is crushed the day before and poured with water from the total volume and boiled in a water bath the next day. For light wallpaper, PVA is added instead of wood glue. Adhesive mixtures are heated in a water bath.
5. After cooking, the glue must be filtered through cheesecloth, folded in several layers, to prevent lumps from entering.
6. Cool to 30-40 ° C, remove the foam.

You can start painting the walls. No need to wait for complete cooling, because. this will reduce the adhesive properties.

STORAGE:

• To store the remaining glue for 5 liters, add 12.5 g of carbolic acid, 25 g of aluminum alum pre-soaked in water or 7-8 g of copper sulphate.
• Optionally, a small amount of substances that repel or destroy insects (10 g of borax or 25 g of chlorophos) are added to the glue.

Flour paste for papier-mâché

The process of making products from papier-mâché, regardless of the method - layer-by-layer gluing of paper of different thicknesses and / or cotton fabric or modeling from paper dough, is practically impossible without a paste.

Cooking:

1. Mix 100 g of flour in a bowl or saucepan with 100 ml of water and beat well with a whisk or fork, then add another 200 ml and beat again. The result should be a homogeneous mass without lumps. If necessary, you can use a blender or mixer.
2. Put this mixture on fire and bring to a boil, but do not boil, stirring constantly, until a thick jelly-like mass is obtained.
3. After cooling, the paste is ready for the layer-by-layer gluing technique. It can be stored in the refrigerator for several days in a tightly closed jar.

ADVICE! For paper dough, PVA or wood glue is added to the paste in quantities determined by the manufactured product.

Flour paste for bookbinding and restoration works

For bookbinding and restoration work, flour paste is used, enriched with glycerin to improve elastic properties and gelatin to improve adhesive characteristics. For antibacterial protection, formalin is added to the adhesive mass up to 1 ml per 100 ml of glue.

For gluing thin sheets, a thick paste is used, and for working with thick paper and cardboard - liquid:

• The recipe for a thick paste made from finely ground wheat flour: for 1 liter of boiled water, 135 g of flour, 12 g of gelatin, 6 ml of glycerin.
• The recipe for a liquid paste made from finely ground wheat flour: for 1 liter of boiled water, 80 g of flour, 10 g of gelatin, 4 ml of glycerin.

Cooking:

1. Soak gelatin in advance for several hours in 50 ml of water, after which it must be dissolved by heating, but not allowed to boil. Cool gelatin to 50-60 °C.
2. Pour the flour into 300 ml of cold water and mix thoroughly.
3. Heat the remaining water (650 ml) to a boil and pour flour with water into it. This mixture must be boiled, stirring vigorously, at 80-85 ° C for 20 minutes, then pour in the gelatin and glycerin.
4. The shelf life of this adhesive when stored in the refrigerator in a well-closed container is 4-5 days.

Flour paste for children's creativity

For any adult, the advantages of a paste for children's creativity are obvious - it is absolutely harmless and safe, easy to use and reliable. With it, you can make an application, a cardboard box or a wall newspaper. This glue is prepared only from flour and water in proportions of 1 to 8-15, depending on the desired density of the glue.

Cooking:

1. The method of obtaining is similar to all the previous ones - first mix the flour with a small part of the water, pouring water into the flour so that the mixture is easier to stir, mix with a whisk, fork, blender (if the amount allows).
2. Then this mixture is brewed with boiling water, stirred and warmed up a little, but not boiled.
3. After cooling to room temperature, the paste is ready for.

ADVICE! Do not make a large amount, it is better to prepare a new portion the next day, although this glue can be stored in the refrigerator for several days.

Often, in different situations, the paste can become a lifesaver, without which you simply cannot do. Now you know how to make a flour paste, where to use it and how to store it.

How do you apply the paste?

An abundance of multi-colored packages with glue on the shelves construction stores is a familiar picture. You can choose compositions for any purpose, for all available types of wallpaper, for any cost. True, the minimum price for such adhesives bites, and the quality of the product may be far from ideal. In addition, despite the assurances of manufacturers, such formulations may be unsafe for health. In such cases, you can make a paste from simple ingredients at home.

During cooking, you need to constantly stir the mass

The word "paste" in itself can serve as a clue how to cook it and what ingredients are needed for this. Translated from German language it means glue made from starch or flour. And no chemical components are needed to cook it with your own hands. The composition includes only water and one of the dry ingredients.

The choice of dry ingredient depends on the further use of the adhesive. For example, flour is more suitable for pasting walls with wallpaper or making children's crafts, since the finished product leaves no residue after application. Accidental soiling is easily removed even after drying. Wallpaper, cardboard, paper for crafts do not soak, the surfaces stick together firmly.

The number of ingredients included in the paste recipe is taken from the calculation:

• wholemeal flour (a product of the 1st grade is suitable) - 0.25 kg;
• water - 1 l.

To make wallpaper paste, you need wholemeal flour

Cooking

Prepare dishes and suitable for proper cooking paste tools. It is most convenient to prepare a paste using:

• a glass container of a small volume (it will be needed for a talker);
• enameled or glass heat-resistant pan (3 l);
• sieve;
• fork or whisk;
• wooden spoon with a long handle.

simple recipe

We cook on an ordinary gas burner or electric stove in the kitchen. Before cooking the flour paste, the flour should be carefully sifted with a sieve to remove dirt and lumps from it. How to cook a flour paste, the instruction will tell you:

1. Make a chatterbox. The sifted flour is placed in a glass container. Then, gradually, with continuous stirring with a fork or whisk, is added to the flour. cold water until a mass of homogeneous consistency is formed in the container.
2. Add boiling water. If you are trying to make a flour paste for the first time, it is better to take the amount of mash and boiling water in a ratio of 1:15. Boiling water is poured in slowly, with continuous stirring. Gradually, the mass in the container acquires density and uniformity.
3. Bring to condition. The resulting mass is heated on the stove, stirring constantly.
4. Cool down. The cooked composition is removed from the fire. Do not use cold water or ice to speed up cooling - this will worsen the adhesive properties. It is necessary to wait until the mass has cooled completely.

Particular attention is required to the stage of bringing to the condition. By adding boiling water to the mash and achieving a thick mass, you will make glue that is quite suitable for children's crafts or making papier-mâché. But for finishing work, the adhesive properties of this product may not be enough.

Stir with a plastic or wooden spatula.

Recipe for wallpaper paste

An easy way to make a flour paste at home, suitable for use during repairs:

1. The mash brewed with boiling water is poured into enamel pan, the container is placed on the stove.
2. Warm up, not bringing to a boil, over low heat.
3. The paste must be stirred during heating.
4. As soon as the first bubbles appear, and the characteristic “puffing” begins, the pan is removed from the stove and left to cool.
5. The film formed after cooling is removed.

All that remains to be done is to strain the finished liquid through a sieve.

How to make the paste stick better

The basic recipe for how to make a paste with just two ingredients is especially suitable in cases where it becomes necessary to spend Finishing work. Gluing wallpaper panels often turns out to be of poor quality even when using adhesives specifically designed for a particular type of wallpaper. As for the flour paste, it can be safely called the best glue for wallpaper. The opinion is quite reasonable, since the home product differs from the factory one in a number of advantages:

• Applying glue from wheat flour for wallpaper on the panel, you can not be afraid of tears and deformation.
• Homemade wallpaper paste makes it easy to detach the panel from the surface using a steam generator or just warm water.
• Has a solid level of adhesion. Copes with any kind of wallpaper, cardboard and plywood. Sticks Decoration Materials even on painted surfaces.
• Differs in the long term of operation.
• It is easy to wash and does not leave stains on the surface of the panels, even with accidental contamination.
• Prepares in minutes and requires minimum investment funds.
• Can be used as a primer before wallpapering.

Ways to correct deficiencies

There is no need to look for a special recipe on how to cook glue from wheat flour. The already known basic instruction is enough. It remains to take care of eliminating the shortcomings that still exist:

1. Poor water resistance. The addition of PVA glue (at least 5% of the total volume) will help correct this drawback, which will make the flour paste more resistant to moisture.
2. The natural ingredients of the paste not only ensure human safety, but also attract pests and a host of bacteria. The danger increases if the composition is used additionally as a primer. However, there is a way to make flour paste unattractive to microorganisms. In the process of cooking, you need to add diluted in water blue vitriol at the rate of 10 g of vitriol per 1 kg of flour.
3. Limited shelf life. The finished product can be stored for no more than 12 hours without loss of adhesive properties. After a day, the composition begins to sour and becomes unusable. Since it is impossible to cook flour paste for future use, it remains to prepare only the required amount of glue.
4. Too thick consistency. During the cooking process, the flour paste thickens, and after cooling, its density only intensifies. In order for the glue to lay down on the wallpaper in a uniform and not too thick layer, the product just made must be moderately liquid. There is an easy way to make the paste the right consistency, not so thick. To do this, just add the right amount of water and warm the composition again.

Despite the disadvantages, flour paste has much more advantages. It takes a little time to prepare it, and everyone will be able to make a universal glue suitable for both wallpaper and for children's creativity.

The need for special blends with my own hands not only due to cost savings. The use of appropriate technology will allow you to personally control the composition and ensure truly high quality. This knowledge will be useful for creating reliable adhesive joints on an urgent basis when there is no time to visit hardware stores. This article describes how to make a paste yourself. There is detailed descriptions relevant methods, features of the use of ready-made tools in practice.

The title of this section specifically limits the scope of the composition. In fact, before proceeding with its manufacture, it is necessary to clarify the intended purpose. AT this case we are talking about creating , to be used in residential and office space. They should not worsen the healthy state of the atmosphere during operation, provoke allergic reactions.

For this reason, you need to figure out how to prepare a paste from safe ingredients. It is advisable to purchase them not expensive, as you have to process large areas connected elements. A sufficiently long service life should be expected so that repairs are not carried out too often.

In addition, it is necessary to take into account the characteristics of the materials used. have good resistance to adverse external influences, but weigh relatively much. Paper-based counterparts are lighter. But they deteriorate quickly high humidity. It is necessary to clarify how to prepare a paste for which will not damage the corresponding coating. In some situations, temperature and other conditions during the course will be of particular importance.

How to make flour paste: time-tested technology

There are no claims regarding environmental safety to this main component. The following advantages and disadvantages of flour should also be noted:

• Attracts low price, availability in any grocery store. It is clear that on the basis of such a component, even large-scale projects can be implemented without excessive financial costs.
• Flour formulations have excellent adhesion characteristics. With the right reproduction of technology ready mix will be no worse than expensive professional analogues.
• If such a need arises, it will be possible to separate from the wall using simple wetting. For this procedure, it is recommended to use warm water (not boiling water) with an exposure time of 10-15 minutes after its application.
• The absence of unpleasant spots, lumps is also an advantage. But in order to create just such a composition, it is necessary to strictly follow the rules of the corresponding recipes.
• A significant disadvantage is the low water resistance mentioned above. The wallpaper is not fixed on the surface steadily. Difficulties are also possible when pasting ceilings.

How to make flour glue for wallpaper is described in the following instructions:

A photo	Action algorithm
	For this product, premium flour is not suitable. It is better to purchase inexpensive wholemeal flour. It retains more of the necessary components.
	It should be remembered that ready composition retains its useful qualities not for long (up to 20-26 hours). Therefore, its preparation must be planned immediately before gluing. You can make a small test batch in advance in order to clarify all the important nuances in practice.
	The cooking process begins with sifting flour. Any standard sieve will do. During this procedure, lumps are separated that do not dissolve well.
	In the prepared flour (500 g) add clean water with simultaneous mixing. A homogeneous mixture should form. Next, pour boiling water, without stopping to interfere. Total liquid will be approximately 1.8-2 liters.
	The use of an electric mixer simplifies this procedure.
	The mixture is heated for or until the first bubbles appear. After that, they are quickly removed and cooled naturally to room temperature. For heating, it is better to use a stainless steel pan. She doesn't change chemical composition mixture, without undue effort, it is cleaned of contaminants. During this operation, do not forget about constant stirring.

Note! On cooling, a film may form on the surface of the mixture. It must be removed. For the separation of other mechanical impurities, the same sieve is used, or a piece of gauze of a suitable size is used. To reduce the sensitivity of the composition to high humidity, standard PVA wood glue is added to it (4-8% of the total volume).

Making Starch Paste: A Recipe with Inexpensive Ingredients

The use of such a main source component allows you to create a mixture that does not stain.

Note! Information on how to make a starch paste will be useful for various construction operations. This composition is well suited for pre-priming walls. After such processing, the wallpaper is glued using conventional technology. This method provides better adhesion on different surfaces.

The cooking technology differs from the previous one in the following nuances:

• For every 2 l. the finished composition consumes from 180 to 220 g of starch.
• When adding water, they provide a consistency similar to that of medium-fat sour cream.
• Ready adhesive solution is used immediately. Its positive characteristics deteriorate faster compared to a flour-based mixture.
• For a more delicate temperature effect, experienced experts recommend using the "water bath" technology. The container with the solution is immersed in a large pot of water, which is placed on the hob.

A technique for creating a high-quality paste for papier mache

This information will help you figure out exactly how to make a papier-mâché paste with the desired characteristics:

• To provide high level safety use the same basic ingredients (flour, starch). It should not be forgotten that children are often engaged in such creativity, therefore, the requirements for all components of the process are increasing. Additional advantage- ease of cleaning hands, tools, clothing, surrounding space.
• Starch-based formulations provide a less stable bond. They don't distort color scheme, .
• With the help of glue, more durable crafts are made from flour. In some cases it White color will not work, so you have to use the previous option.

For the preparation of mixtures, the recipes discussed above are used. Density is adjusted taking into account the parameters of specific products. As with wallpaper, it's best to get started as soon as possible. In extreme cases, you can store the finished composition (40-48 hours) in the refrigerator compartment at a temperature of +4°C to +6°C.

Other adhesives

The following technologies are used to create various designs using adhesives. Some recipes are as effective as high-quality factory samples.

How to make PVA glue at home

No need to think that everything you need for construction, or creating homemade products can be purchased in modern stores. Sometimes needed special color. In other situations, increased resistance to water is required. Making glue with your own hands allows you to get unique characteristics.

But before studying production technologies The features of this category of products should be listed:

• The name contains some of the ingredients. PVA is a polyvinyl acetate compound.
• It has excellent adhesive properties. If the manufacturing technique is followed, the tear strength of the adhesive bond can exceed 450 N/m.
• AT liquid state glue loses beneficial features in severe frost. But the created connection is resistant to low temperatures.
• This composition does not contain components hazardous to humans. It is still recommended to avoid getting it on the mucous membranes, in the eyes.

The following PVA glue recipe will help create a quality composition on your own at home:

• First you need to prepare a mixture based on a fine grade of gelatin (10 g for every 100 g of water). It is stirred and left for 24 hours in a room with a positive temperature.
• The next day, you need to take the necessary containers to heat the components using the "steam bath" technique.
• First, raise the temperature of the initial mixture to a boil. Next - flour is poured very slowly (100-120 g for the above doses) with stirring. This procedure without the formation of lumps will take at least 50-60 minutes.
• At the next stages, alcohol (30-40 g), glycerin (10-15 g), coloring pigments are added successively in the same thermal regime (the required amount is used). Continue heating for 25-30 minutes, after which the mixture is cooled.

Note! The shelf life of the adhesive in sealed containers at temperatures above 0°C is 6-8 months or more

How to make glue from Styrofoam and Gasoline

The low cost of such a composition largely explains its popularity. Required amount the foam is placed in a container resistant to the corresponding chemical compounds. It is filled with gasoline. With the use of mixing create a fairly homogeneous viscous mass. It is applied to fat-free surfaces, squeezed, left in this position until completely dry. To create the desired force, a load, a clamp, a vice are used.

It is difficult to determine which better glue, from polyfoam in acetone, or gasoline. In both cases, the liquids act as a solvent. After their evaporation, a sufficiently strong connecting layer is created that cannot be deformed. It is used for fastening metal, wood and other solid products. Here it can only be noted that acetone evaporates faster. Either compound can be harmful to human health, so it is necessary to ventilate the room well, or transfer work operations to the open air.

"Super" glue and other special compounds

When studying thematic information, you can find different tips how to make super glue at home. In particular, it is proposed to use the dissolution of the foam with nail polish remover. But the main active ingredient of such products is acetone, so the recipe is not original. There are also tips using vinyl acetate (copolymers chemical compound). It is difficult to acquire this substance, and the exact observance of the appropriate technology is accompanied by additional difficulties and costs.

If you are thinking about how to make hot glue at home, use a due diligence different options. This approach leads to the conclusion about the preferred use of methods based on flour and starch. A little more difficult - a mixture of PVA. The use of solvents comes with increased security measures.

One of the clear advantages self-manufacturing is obtaining special technical and aesthetic characteristics, solving various unique problems.

It is impossible to do without binding components either in children's creativity or in construction, and glue usually plays their role, but it is not suitable for all actions. For example, for pasting a room with wallpaper or working with papier-mâché, it is much more reasonable to use a paste. At home, it is prepared in a few minutes, even a child will master the technology, and it does not matter which of the cooking recipes to study.

The easiest paste recipe is flour. It is he who is taught to cook kids in labor education lessons, and it is he who is considered a safe and easy-to-use means for fastening light materials: for paper, for leaves, for seeds - flour paste is suitable for absolutely everything. It is used not only when creating any crafts, but also when sealing cracks in old wooden windows.

To cook flour paste at home, you only need a sufficient amount of water and the flour itself. In most cases, wheat is used, as the most affordable and available in every home, but professionals advise taking coarse rye to enhance the binding effect. True, a rye flour paste will have a dark tint and may be noticeable when working with light materials.

To cook the paste, you need an enamel bowl, a saucepan or even a bucket (depending on the volume you need). Cold water is poured into the container, and as soon as it boils, flour is introduced into it in a thin stream. As soon as the grains of flour touched the water, it is necessary to start stirring the liquid, otherwise the flour will simply accumulate on the surface, and then it will settle in a dense lump. Despite the fact that the paste is a "fighter of the invisible front", and his appearance does not catch the eye, the consistency should be made as homogeneous as possible. Therefore, the flour is poured very carefully, and the mass is stirred continuously.

The amount of flour is rarely calculated in advance: it is added by eye, until the mass begins to resemble batter. When it cools, it will thicken, so it’s better not to add flour than to overdo it: then you will have to heat the paste again, add warm (!) Water, boil it again a little. The approximate ratio of flour and water for paste is 1:3 or 1:4. It also varies depending on the orientation of the product: if you want to paste the wallpaper to fit it on the wall, a ratio of 1:2.5 is also possible (for vinyl wallpaper), and 1:3 (for thin).

It is worth noting that if you are preparing a paste for paper wallpaper, before it starts to cool, it is recommended to introduce a little ordinary wood glue into the finished mass (for dark wallpaper) or PVA glue (for light). It is advisable to cook the paste itself after boiling the paste in a water bath in order to reduce the likelihood of bubbles appearing on the surface of the composition.

Paste for papier-mâché:composition features

By and large, for papier-mâché use universal option flour paste, however, it is made more liquid (flour to water 1:5 or more), and ingredients such as PVA glue, glycerin are often added. In this case, even the cooking technology may differ from the above.

Sifted flour is poured into an enameled bowl and poured over it. cold water in the same volume: i.e. 1 part flour and water. Beat the components with a whisk to get a thick mass without lumps. After that, the remaining parts of the water are poured in (2 or 3, because for papier-mâché the paste is boiled very liquid), the container is placed on the stove, the liquid is brought to a boil. In this case, the mass must still continue to stir and beat lightly. When the flour is completely dispersed in water, 5-10 ml of glycerin is added there, the container is removed from the burner, the resulting liquid is decanted through cheesecloth. The paste is used only in a chilled (to room temperature) form.

The paste, cooked not on flour, but on starch, has both undeniable advantages and some drawbacks. The latter are in bad smell from finished product, which appears after 5-6 hours, so the starch paste is boiled in a very small portion and for immediate use. But its advantages depend on the chosen starch: corn starch is recognized as the best, since the mass turns out to be the most pleasant in consistency, the paste quickly impregnates the material, dries no less quickly, and fixes it perfectly. Rice and potato starch proved to be a little worse. And any starch allows you to make the fact of using a paste unnoticed, since the liquid will not leave stains.

PVA glue is sometimes added to the starch paste, all with the same purpose of strengthening the fixation of parts, as well as changing the shade of the finished product - the paste will become almost completely transparent. It happens like this:

• 1 part flour is poured into a small container, after which 1 part is carefully poured into it. hot water(boiling water). The mass should immediately begin to beat while you pour in the water.
• At the same time, water is brought to a boil on the stove in the amount of 3 parts. As soon as the water boils, and all starch lumps disperse in a small bowl, the contents of the latter are poured into boiling water, and the mixture is gently whisked with a whisk.
• Immediately after this, the container is removed from the stove, the paste is continued to be mixed, giving it uniformity. As soon as it cools to room temperature, PVA glue is injected into it. The amount of glue per 1 liter of paste is approximately 100 ml.

In some cases, starch is calcined on a baking sheet in the oven before it is cooked so that its lumps darken to Brown color. Then it is ground and passed through a sieve, and after that it is mixed with water. Occasionally, 1-2 tablespoons are added to starch. sugar to enhance the adhesive power.

At home, you can make glue from ordinary flour, which is in no way inferior in quality to that made in an industrial environment. You can use it not only for crafts, but also for sticking paper wallpaper.

Advantages and disadvantages of flour paste

Flour paste is intended only for gluing light materials. And in terms of quality, it is in no way inferior to store-bought adhesives. Plus, if to increase the shelf life of such formulations, manufacturers add not too beneficial for human health chemical substances, then the paste, cooked at home, is absolutely safe. It does not cause allergies, it is easily washed off the skin with water even without soap, and the hands do not crack or peel after it.

Properly welded paste can also be used for wallpapering. True, with the help of it you can stick only light canvases on a paper basis. Since such compositions are easily soluble in water, old wallpapers will be easily removed from the wall - they just need to be wetted with water and then removed with a spatula.

Advice! Be sure to pay attention to percentage gluten in flour. The higher it is, the better the glue will turn out. Perfect option– 25-28% gluten.

For the paste you will need flour with a high gluten content.

Manufacturing instructions

So, we tell in detail how to cook flour paste:

For a couple of rolls of wallpaper, you will need about a liter of water (5-6 tablespoons of flour are added to this amount of water); in consistency, it should resemble a fairly thick jelly:

Dilute the flour first in a small amount of water;

In a thin stream, gradually add, stirring (it is more convenient to do this with a whisk), boiling water into the resulting mixture;

We put it on water bath and cook for 5-7 minutes so that it thickens;

Cool, if necessary, filter from lumps;

To improve the adhesive properties, PVA can be added to the cooled glue;

The glue is ready to go.

Despite the fact that it is not difficult to cook such glue, there are some subtleties in its manufacture:

It can be made not only from flour, but also from starch;

So that lumps do not form in it, it is better to sift the flour through a sieve;

It is poured in gradually, otherwise it will immediately grab into a large lump;

If the glue turned out to be liquid, it does not matter; put it back in a water bath and boil a little again;

Paste, cooked at home, is not stored for a long time, so it is not prepared for the future; the remains of unused glue are best stored in the refrigerator for no more than 1-2 days.
