All the ingredients are mixed in enameled dishes and a certain amount of warm water is added until a liquid dough is formed. In a separate saucepan boil the water and at the moment of boiling pour this liquid dough. All mix. Then add carpentry glue, preheated. That is, hot joiner glue is kneaded in a hot paste.
The solution is then filtered through a sieve or gauze. It is necessary to ensure that the clumps and lumps contained in the mixture do not fall on the wallpaper. The mixture will become more homogeneous and easily applied to the substrate and the material. In addition to homemade, you can buy a dry paste, the preparation of which is indicated on the package.
