Check the cleaning of the base surface and base course, including the removal of sand and ash caking, floating sand and dust on the wall, to improve the flatness and adhesion of the base course of the putty powder construction surface, and ensure that the base surface is free of pollution, hollowing, cracks, looseness and powder loss.

The construction environment has always been a very important factor. If the ambient temperature is too low, it is easy to 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 quality and construction performance of the putty after batching. The construction environment is neither too hot nor too dry. The putty construction should be carried out at 5 ℃ - 35 ℃.

The putty shall not be too thin or too thick. If the putty layer is too thin, it is easy to lose water too quickly, which will lead to putty pulverization, and will eventually affect 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 batch thickness of single putty is better between 0.5mm-1mm.
