Ways and rules of cooking

Home paste is not inferior in characteristics to the purchased compositions for gluing paper and other materials. It is used both for fixing parts of small crafts, and when conducting large-scale construction work. Safety, full availability of ingredients, ease of preparation make the mixture on the basis of flour popular and in demand. There are many ways to make paste. Choose a suitable recipe should be based on the purpose of the adhesive and the characteristics of bonded surfaces.

From flour for wallpaper

For the preparation will require only flour and water. The resulting mixture is suitable for thin ordinary paper sheets and for dense vinyl. The only thing is necessary in the process of cooking to adjust its thickness. It is better to prepare the wallpaper paste from second-rate flour, since it contains more gluten, which improves its characteristics.

Even a child can learn how to prepare a simple paste. In the capacity of the calculation of the amount of the mixture is poured water and heated on the stove. After waiting for boiling, pour flour into the center of the bowl, constantly stirring. The amount of the main ingredient is not calculated in advance, it is easier to add to the eye.

For simple wallpaper, the mass should resemble liquid sour cream in consistency. For heavy cloths of flour it is better to add more and thicken as much as possible. Use the paste is necessary while it is warm, as it gradually cools, it loses its properties.

It is not recommended to make a paste on rye flour, it will get a dark shade and may appear through the wallpaper.

From starch

Such a paste is prepared if you need a transparent mass for pasting, which will not leave spots. The technology of preparing an economical composition is not much different from the flour mixture. Starch is sieved into an enamel bowl, poured with a portion of cold water, stirred. Then add a portion of boiling water without stopping agitation. Cook starch paste to the desired density, breaking all the lumps.

A do-it-yourself mass of starch has both advantages and disadvantages. It quickly grabs, firmly bonding even heavy materials, does not leave stains and does not turn yellow. When removing dried glue, just wet it with warm water. The most pleasant texture is corn starch. Rice and potato product manifests itself worse, which affects the transparency.

The disadvantages of starch mixture include a small shelf life. After 5-6 hours after cooking, an unpleasant smell appears. Even in the refrigerator, he can stand without loss of quality for more than a day.

For papier mache

The popular technique of making handicrafts from paper involves the consistent pasting of the form with a material impregnated with glue. To create a quality figure, you need a lot of adhesive mixture, so it’s convenient and beneficial to make it yourself from cheap and affordable materials.

The papier-mâché pasteboard is made from flour, hot water, and salt. The main ingredient can be replaced by starch, but then it will have to be brewed in small portions. The process will be unjustified, if you need to create a large crafts.

The proportions of the ingredients must be chosen taking into account the density and type of paper. For newspapers and easily absorbent materials, a ratio of 5 parts of water - 1 part flour - 1 teaspoon salt. Magazine sheets and cardboard soften and fix the mixture with the addition of wood glue or PVA.

To make papier-mâché crafts shiny, vanillin and sugar can be added to the paste.

Dextrin paste DIY

On the basis of dextrin it turns out high-quality glue, which perfectly fastens thick paper with any coating, leather, fabric, wood, plastic. The substance is obtained from starch by its cleavage. Dextrin powder is faster and better soluble in water; a sticky mass based on it is easy to make at home. To prepare the paste correctly, you must adhere to the following recipe conditions:

Pour the starch on a baking sheet and place in the oven;
Set the heating temperature to 160 ° C and leave the powder for 2 hours;
After a while, we take out the yellow dextrin and cool it at room temperature;
Mix the substance with boiling water in equal parts;
Continuously interfere until complete dissolution.

The resulting mixture should be used immediately after preparation, because it thickens very quickly. If it is necessary to postpone its use, when cooking, increase the amount of liquid and add a few drops of glycerin. Store dextrin mixture can be in the refrigerator in a sealed tight package, excluding contact with oxygen.

Pasteur with the addition of PVA glue

PVA glue, as an independent composition, is a very effective bonding material. Sometimes its texture is done less often by adding water. In this case, the quality characteristics are reduced. If it is necessary to obtain a moderately liquid mass and preserve all the original properties, PVA is added to the usual flour paste. This will help reduce the adhesion of the pure product.

The recommended proportions for making a small portion of paste are 100 g of flour, half a liter of water, 2 tablespoons of PVA. Flour is added to boiling water, boiled and the mixture is kneaded for 5 minutes. After complete cooling poured pva, shaken.

Additive can be added both in flour, and starch ready paste. The mixture becomes suitable for gluing heavy non-woven wallpaper, textiles, wood. Weight with PVA will be stronger, retain transparency.

Carter with wood glue

Based on the use of the mixture, various additional substances are added to it. Ideal option for increase of the fixing qualities - joiner's glue. Do not forget about the color of the surfaces, because the material for wood will give the adhesive mass a dark shade.

Animal glue is added to the mass for priming the walls under heavy wallpaper, or to firmly fix the old paint on the panels, which is difficult to clean. The proportions in this case are selected 1: 1. Water is brought to the desired thickness. For pasting surfaces with a linkrust or other materials on a fabric, plastic base, the mixture is prepared from 2 parts of flour and 1 part of wood glue.

Conclusion

Due to the availability of ingredients, the paste will always be popular. The welded mass on the basis of grain crops perfectly fixes paper, plywood, plastic and even fiberboard plates. Adding to the recipe silicate glue or PVA, you can get a mixture for firm fixation of tissue, cellulose cloths. The only drawback of the paste is the possibility of damage by the fungus and microorganisms due to the edibility of dextrin fibers. Additive copper sulfate and other metal salts will help solve the problem.
