Check the cleaning of the base surface and base layer, including removing sand and ash lumps, floating sand, and dust from the wall surface, to improve the smoothness and adhesion of the putty powder construction surface base layer, and ensure that the base surface is free from pollution, hollowing, gaps, looseness, and powder loss.

The construction environment has always been a very important factor. If the environmental temperature is too low, it can easily affect the dissolution of organic additives in the putty. If the additives cannot be fully dissolved or the dissolution rate is too slow, it will affect the film forming quality and construction performance of the putty after scraping. The construction environment is too hot or too dry, and putty construction is suitable to be carried out in an environment of 5 ℃ -35 ℃.

The putty batch should not be too thin or too thick. If it is too thin, the putty layer may lose water too quickly, leading to powdering of the putty and ultimately affecting the coating effect. The thicker the putty layer is scraped, the greater its dry shrinkage strength and the easier it is to crack. Therefore, the optimal thickness for a single batch of putty is between 0.5mm-1mm.
