Generally used putty can be divided into three categories according to different engineering projects and different uses:

Glue old powder putty: It is made up of old powder, chemical glue, gypsum powder and bone glue; it is used for water-based paint flat top inner wall.

Oil-faced putty: It is formulated from oil-based varnish and gypsum powder and is used in oil-based coatings such as steel-wood doors and windows.

At present, the largest amount is construction putty. According to the performance, it is mainly divided into water-resistant putty, 821 putty and rubberized putty.

——Water-resistant putty refers to the putty that can reach the “N” standard in JG/T3049-1998 “Building Interior Putty”;

—— TYP putty is a putty that does not have water resistance, and can only reach the “Y” standard in JG/T3049-1998 “Building Interior Putty”;

——Adhesive putty is generally divided into two components, glue and ore powder (such as white powder, talcum powder, etc.), which are mixed by workers on site, which is a backward practice; however, there are still many places to follow.
