Flour adhesives for wallpaper: recipes and recommendations. Wallpaper paste - features of self-preparation of the composition

Now the market is full of various adhesive products, and earlier they cooked such a mass themselves, and in quality it surpassed many modern analogues. How to make a paste that our grandmothers cooked? There are two proven recipes and several recommendations for choosing ingredients.

What it is

A paste is a do-it-yourself gelatinous adhesive. The composition is used in needlework and less often in repairs (mainly for wallpapering). It does not contain harmful additives, which cannot be said about industrial products. It is thanks to safety that the paste is still relevant. It is a good substitute for PVA.

What is the advantage of making and using a paste for a modern person:

This is an environmentally friendly product. All stages of preparation are traceable. You can be sure that the composition is safe, unlike what the chemical industry offers.
The paste replaces expensive adhesives, its cost is very low, in fact, it is equal to the cost of flour or starch.
Easy to cook, products are available at any time.
Practical and easy to use formula.
If you need to remove the wallpaper pasted on the paste, it will not be difficult: just wet the walls, and the coating will come off without leaving a trace.

Of the minuses, it is worth noting the short shelf life. At room temperature it must be used within a day. If you put it in the refrigerator, it will last there for 2-3 days, but it will still deteriorate, and you will have to throw it away.

To prepare the paste, a minimum of products is used: ordinary wheat / rye flour or starch. To make the composition as convenient as possible for use, you need to adhere to some principles in the choice of components and tools:

The flour is of low quality. It is this product that gives the adhesive mass the necessary viscosity. Flour premium will not provide the glue with the desired consistency.
Before use, the flour is sifted through a sieve to get rid of lumps.
In order for the mass to mix well, you will need a mixer or blender. But it is permissible to stir with a metal spoon - the main thing is that there are no lumps.
The pan or basin is taken non-stick.

Cooking rules

To prepare a paste, it must be boiled. To do this, a mushy mixture of flour and water is made, placed on the stove and heated over low heat until all the lumps disappear.

Rules for making paste:

Water is heated on the stove.
Flour is poured in a thin stream and quickly, to get a more or less uniform consistency, stir.
The approximate ratio of the bulk component and water is from 1:2 to 1:8.
The process must be closely monitored so that the mixture does not burn.
The composition should be cooked on low heat.
During the cooking process, the paste is stirred with a wooden spatula.
Ready hot glue is not used in the work. It needs to be chilled first.

Advice! So that the glue definitely does not burn, it is recommended to boil it in a water bath, but the process will take longer - from 15 to 20 minutes.

Wallpaper paste

In the preparation of homemade wallpaper glue, you need to follow the instructions so that the composition is of good quality.

Step-by-step recipe for making paste:

Sift a glass of flour so that no lumps remain.
Add cold water small portions, while stirring constantly. You need to achieve the consistency of thick sour cream.
Stir the solution thoroughly so that all visible lumps dissolve.
Now you should add water and bring the total volume of the mixture to 1 liter. If it turns out too thick, it is allowed to add a little more water, but now hot.
0.5 tbsp is introduced into the mixture. PVA glue, everything is thoroughly mixed. This component will provide viscosity and quick setting.
Alternative additive -. It will help with gluing painted walls.
Put the pot with glue on a minimum fire and cook until bubbles appear.
Now you need to remove the dishes from the heat and stir all the lumps. It does not hurt to filter the composition through gauze folded in several layers - it is important to be careful not to burn yourself.
The paste is ready. It should be gelatinous and transparent. It remains to cool it and use it for its intended purpose as a regular wallpaper paste.
If a film forms on the surface, it must be removed.

Advice! Let the paste cool down naturally, do not put it in the refrigerator.

Composition for creativity

For papier-mache work, gluing crafts, creating appliqués and other creative purposes, it is very easy to prepare good glue at home.

How to make such a composition:

At the bottom of the pan, 1 cup of rye or wheat flour is poured.
Pour 1 glass of water, stir with a mixer.
Gradually add 2 more cups of water. The mass is stirred, you need to get rid of lumps.
The pot is placed on the stove. The mixture is brought to a boil over low heat.
Immediately after boiling, the container must be removed from the stove.
Wait until the adhesive has completely cooled before use.

Such a composition is stored in sealed glass containers for up to 2 days. Paper products fastened with such a paste will hold firmly.

Starch paste

Instead of flour, potato starch is also taken to create a paste. The starch-based composition has the same strength, and the method of its preparation is similar to the previous ones:

In 10 tbsp. dilute water with 1 tbsp. starch and mix well.
Add another 0.5 tbsp. water, stir the lumps.
If too thick, dilute with a small amount hot water.
The mixture is boiled over low heat until it boils.
It is allowed to use the cooled starch paste after 10 hours.

On a note

Welding glue at home is a simple task, but you also need to apply it correctly. These tips will help you weld and use the paste as efficiently as possible:

The paste is consumed within one day, no longer, as it quickly turns sour.
The substance is not used for gluing dense and quality wallpapers. His competence is paper wallpaper medium density.
Paste, especially from rye flour, is not recommended for frankly thin or light wallpaper, because it can leave yellow spots that will show through.
To make a paste that repels insects, add a little karbofos to it.
In heat, the paste loses its characteristics. It should be stored in a cool place or at room temperature (+18-20˚ C).
It is necessary to prepare the composition immediately before use. The maximum adhesive properties are revealed at a paste temperature of 40 degrees.
Instead of potato starch, corn starch is often taken. The result is just as great.

Paste is a worthy analogue of modern adhesives. Its main advantages are safety for humans and low cost. Everyone can cook a paste, this is another plus. The use of home glue greatly simplifies life: saves money, protects against poisoning. The paste is good both for repair and for creativity.

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

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

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

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

Preparation methods and compositions

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

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

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

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

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

Dissolve flour in cold water

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

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

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

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

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

It is better to use flour 1, and not the highest grade. A coarse grind mixture will provide better adhesion.

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

Starch-based composition and mixed look

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

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

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

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

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

The right flour paste for wallpaper

How to make starch paste for wallpaper

Despite the wide range of adhesives offered by stores building materials, starch paste is still widely used for priming walls, creating paper applications, insulating windows and decorating walls with wallpaper.

Main advantage homemade paste from starch - transparency. The composition does not leave marks and stains even on delicate paper. If the paper glued with this tool has to be removed, this can be easily done with warm water.

The main thing is not to make a mistake with the amount of starch. I take no more than a kilogram of powder per bucket of liquid. This ratio of ingredients will make an almost perfect starch paste.

First, prepare the starch. Sift thoroughly to minimize the chance of lumps. Pour prepared raw materials warm water and stir. The result is a mass that resembles batter.
I will introduce water into the starch slurry in a thin and continuous stream. For this purpose, I recommend using a teapot. Stir the mixture thoroughly until a homogeneous mass is obtained. Mix vigorously using a long stick, breaking up any lumps. After brewing, the paste will become transparent. As it cools, it becomes thicker.
Strain the hot mass carefully. A sieve or colander lined with gauze is ideal for this purpose. There should be no lumps left in the finished adhesive composition. Otherwise, the result further work turn out to be unsatisfactory.
The paste is characterized by poor resistance to moisture. To increase the adhesive ability, include industrial additives in the composition. A glass of wood glue is enough for a bucket of the mixture.

Cope with the task if you correctly calculate the amount of raw materials. Remember, you cannot add boiling water or powder to the finished mixture. Since the adhesive ability of the agent decreases quickly, do not make stocks.

The prepared mixture is suitable for priming walls painted with oil paint. True, in this case, it is not worth using industrial additives, since the composition enriched with them will leave pollution on paper. If problem skin of the face is tormented, try not to get the composition with additives on it.

Buying wallpaper glue is not difficult. There is a suitable mixture for every type of wall covering. However, sometimes there is no opportunity to buy glue, and the work needs to be completed urgently. There is only one way out of the situation - self-preparation of the paste. technologies, instructions and step by step recipes from flour and starch I shared. Now I will highlight six main advantages of home lineups.

The adhesive composition or paste, welded on water from grain processing products, is considered one of the most proven and safe types of glue for homework. The uniquely simple method of preparing the adhesive mass is combined with good mechanical strength of the seam, therefore, even with the advent of water-soluble adhesives based on methylated cellulose, flour and starch paste remains revered among do-it-yourselfers.

High-strength paste can be prepared in three ways:

On flour, even if the raw materials have long lost their food qualities;
Using crushed or ground grain;
Cook on any available grain starch.

For your information! To achieve maximum strength seam, paste can best be welded on dried and pounded grain.

True, the yield of grain paste is somewhat less than if the paste mass is cooked from flour. In addition, you will have to work hard to remove the remnants of the screenings and husks, but with due care, you can brew a paste that will even firmly stick vinyl wallpapers.

How to cook flour paste

In order to properly weld and not burn the paste, you will need an enameled or metal non-food utensil with a tight-fitting lid and a steel or cast-iron flame diffuser installed above the gas burner. A simple device allows you to safely heat the paste, cook flour grains, and at the same time avoid overcooking the glue mass into jelly.

Proportions of water and flour

In order to cook a paste, you will need three ingredients:

Purified water, you can use filtered or settled tap water. The main thing is that rust, organics or scale do not get into the paste. To cook a liter of paste, you need 800 ml or four glasses of water;
Corn or wheat flour, per liter of adhesive mass is calculated 250 ml of flour. It is best to cook a paste from wholemeal flour, second or third grade;
Ethyl or formic alcohol, about a tablespoon per liter of the mixture. The additive helps to get rid of lumps and air. It is possible to cook glue without alcohol, but alcohol promotes the hydrolysis of gluten, even if the water is very hard and contains a large amount of salts.

For your information! Wallpaper makers advise adding a small amount of soda ash solution, aluminum alum or stationery glue.

Before the appearance of specialized brands of glue for wallpapering, during mass construction, it was necessary to boil the paste in tens of liters. Additives helped to weld the glue quickly and at the same time ensure storage for several days. At home, you can add alum, this will help to cook a paste that is resistant to fungus and cockroaches. The use of any other additives requires some experience in handling the paste solution.

Cooking and adjusting consistency

You can cook the paste in 10-15 minutes. Slightly warm water is poured into a clean container, about 1/3 of the calculated amount, and flour is added in small portions, approximately in the same volume. The mixture is intensively stirred until a homogeneous mass is formed. The rest of the water is brought to a boil and, continuing to stir the mass, is added to the paste.

Next, to weld the glue, the container is transferred to a tile with a divider and heated for ten minutes for strong fire. As soon as the paste acquires the texture of a thick milk jelly, the tank with glue is transferred from the fire and cooled in water.

It is not difficult to weld the paste, but you need to carefully monitor the consistency of the glue. In the process of cooking, the paste mass seems too liquid, and when cooled, it thickens strongly. If you do not calculate with the proportions and amount of hot water, the glue most often turns out to be too thick and viscous.

In order to adjust the composition, you need to cook a new portion of a thicker or liquid glue and mix hot with the first paste. The viscosity of the adhesive mass depends on the content of gluten and proteins in the flour, the quality of the water and the precise proportions.

Storage

You can change the consistency of a too thick paste that has stood in the cold for a couple of days with the help of a large number not too hot water. If a sour smell appears, the adhesive mass must be boiled over low heat, then add a spoonful of alcohol and mix thoroughly until smooth.

Masters advise to cook the paste a couple of hours before using it and try not to store it for more than one day. You can store the paste without additives and preservatives for one or two days in the refrigerator, in a carefully sealed container. If you need to cook and store a large amount of starch glue for some time, then at the stage of final boiling, the hot mass is divided into several containers, cooled in a water bath and pour half a teaspoon of alcohol or vodka into each jar. Using this technology, you can weld, store and use glue for a week.

How to cook starch paste

In order to cook glue from corn or wheat starch, you need to make a batch: add 1 part of dry starch to 4 parts of slightly warm water. The batch must stand for one and a half hours to swell the starch grain. Next, the mixture should be boiled for 10-15 minutes over high heat, stirring with a spoon or spatula. Even before half an hour, the paste is boiled on a small or medium flame until the glue becomes transparent. Cool in a water bath.

It is easier to weld glue from starch than from flour, but its strength is clearly inferior to flour and, especially, grain adhesive material.

Application of paste

One of the advantages of starch paste is its good penetration into the pores of the walls. For example, a solution of 100 g of alcohol and 200 g of a starch solution can be primed on painted walls or plaster, on which damp spots regularly appear. In the latter case, the paste must be welded with the addition of 10% PVA glue or aluminum alum at the final stage.

It is believed that if you prepare an adhesive mass with the addition of 40 g of calcium chloride per liter of glue, then the pasted wallpaper will not fall off even if the base is strongly moistened.

For light wallpaper

The best option for light wallpaper is a slightly more liquid starch paste than usual. Glue can be cooked from potato starch with the addition of a small amount of PVA. The polyvinyl acetate emulsion is introduced into the almost cooled adhesive and mixed thoroughly. Such glue does not stain, practically does not show through a thin wallpaper, but it is best to use it within a day, or cook it and store it in the refrigerator in conservation mode.

For heavy wallpaper

Even experienced craftsmen prefer to glue non-woven or vinyl wallpapers on expensive branded Methylan, although under heavy wallpapers you can weld very strong glue from cornmeal or starch. If the texture and pattern are light, then the same PVA is added to the paste, for darkened shades, you can cook a starch mixture with the addition of liquid casein glue. It is clear that in any case, the starch must be prepared, cooled, allowed to stand, and only then the additive should be added.

For fabric crafts

Gluing all kinds of toys and fabric crafts requires a large amount of glue, which you can successfully weld yourself. Moreover, if you choose the right additive, you can weld several liters of glue at once, and it will not disappear and will not lose its characteristics, even if it is stored at room temperature.

For strong gluing of the fabric, you need to weld the grain paste. Wheat or oat grain is broken on an electric coffee grinder to the state of ground coffee. The mass must be cooked without sifting. After swelling, the mixture is pressed through a gauze napkin, a small amount of alcohol and PVA are added, and the glue is ready. For heavy fabrics, instead of PVA and wheat, rye grain can be brewed in a water bath with the addition of wood glue and alum.

For papier-mâché

As a working adhesive composition for the formation of a shell from thin sheets paper, a base of cornstarch with the addition of 10% alcohol and ready-made wood glue is used. Such a composition quickly impregnates the paper and dries well in thick layers of cellulose fiber 3-4 mm thick. If the paper has a laminated coating, then for papier-mâché, an adhesive composition with the addition of PVA, acrylic or bustilate is used.

Conclusion

Clayster has always been very comfortable material, knowing the recipe, you can weld glue for almost any cellulose materials and cotton fabrics. Grain adhesive can be used to fasten plastic and even fiberboard. The only significant drawback is the edibility of dextrin fibers, starch and flour are easily damaged by fungus and insects, so additives based on vitriol or other metal salts have to be used.
