Paste used for pre-priming the surface directly under the wallpaper (slips), as well as for sticking the wallpaper. To obtain dissolved 4 parts glue CMC in 96 parts water (by weight) with a temperature of 15-30 ° C. To speed up the dissolution of CMC mixture is heated to 50-60 ° C. Higher temperature is unacceptable, since adhesive properties of CMC reduced. Viscosity of the glue at a temperature of 18-20 ° C by viscometer VZ-4 is 25-30 sec.
