How to cook a paste from flour or starch with your own hands, recipes

When we are going to glue wallpaper, we go to the store and buy wallpaper paste, believing that this is the best way out. The use of ready-made glue saves time, and the result is good. But if you like to do everything with your own hands, want to save money, or if you need just a little glue, then you can replace it with a paste. In the article we will tell you from what and how to cook the paste yourself.

What is a paste

A paste is a self-made adhesive made from natural ingredients, flour or starch. The tool is suitable for pasting walls and ceilings with wallpaper, as well as for working with crafts made of paper and papier-mâché. Homemade glue is valued for the absence of harmful impurities.

The advantages of the paste include:

• environmental cleanliness and safety of the product;
• low cost – to make a paste, you only need starch / flour and water;
• ease of preparation – the preparation procedure will take several minutes;
• availability of products – ingredients can be bought at any grocery store;
• ease of use;
• fast setting with any surface;
• easy wallpaper removal.

One of the disadvantages of the product is the short shelf life after preparation. When performing work, it is important to take into account that the solution deteriorates quickly. At room temperature, it is advisable to use the glue within 24 hours. It will last a maximum of 3 days in the refrigerator.

What can paste be made from?

To prepare a paste, you will need rye, wheat flour or starch. Options with mixing ingredients are possible. Glue of different properties is obtained from different flours. It is wrong to choose from which flour the paste will turn out better. Each has its pros and cons.

From starch, corn is preferable – it contains a lot of gluten, which has a positive effect on the properties of the product.

Potato starch glue will turn out clean and transparent, but it sets slowly, quickly turns sour in heat, and changes properties when exposed to air for a long time.

The composition prepared from wheat raw materials has an average hardening. It is versatile and can be used in bookbinding, wallpapering and making toys.

Paste, cooked from rye flour, is characterized by increased strength. Among the advantages of glue made from rye flour, moisture resistance is noted.

It is advisable to adhere to the following rules in order to get a quality paste for use:

• Do not take the highest grade flour – when dried, the paper web turns yellow.
• Choose a second-rate coarse grinding product. This will provide the adhesive mass with the required viscosity.
• Sift flour through a sieve before using to get rid of debris.
• Stir the solution well until the lumps disappear.
• Use an enameled basin or pan or stainless steel utensils.

Advice. The components of the paste attract insects. It is advisable to mix karbofos when cooking. To protect against mold, 100 g of copper sulfate is added to starch glue per 1 g of the product.

Homeowners do not replace old wooden windows with plastic ones because of the cost or to preserve the individuality of the house.
