What is the putty in the decoration?

Putty is a kind of surface filling material that pretreats the surface of the wall base before coating latex paint on the wall. Its main purpose is to fill the pores of the wall surface, correct the curve deviation of the wall surface, and lay a good foundation for obtaining uniform and flat latex paint effect.

As the saying goes, "three parts paint, seven parts putty". Only using high-grade and high-quality latex paint can not achieve good wall decoration effect, and it is most important to choose high-quality putty to lay a solid foundation. The ancients said: "If the skin does not exist, the hair will be attached." Latex paint and putty are just like hair and skin; Without skin, hair naturally loses its foundation of existence; Without putty, latex paint loses its prerequisite for attaching to the wall. Without good putty, even the best latex paint will not help. In a sense, putty is more important than latex paint, which directly determines the comprehensive performance, overall decoration effect and decoration quality of latex paint after molding, and also affects the degree of indoor pollution.

Putty can be divided into two types: finished putty and field blending putty.

The so-called finished putty refers to the putty made by the factory, mostly dry powder, which is usually packed in paper bags or plastic woven bags. The production of finished putty needs good equipment, and glue will not be used in raw materials, which requires very high formula technology. Its quality level is limited by two national standards, one is JG/T 3049- 1998, and the other is GB 18582-200 1, which is the limit standard of harmful substances in interior wall coatings of indoor decoration materials.

On-site preparation of putty refers to the putty artificially prepared with materials such as Shuangfei powder, cooked rubber powder and glue at the construction site. On-site mixing putty is the most widely used putty in the decoration market at present, which is also the reason why the quality of wall decoration in many families is not high. There is no doubt that the putty prepared on site can not meet the quality standards stipulated by the state anyway. For example, its waterproof and moisture-proof performance can not meet the standard, and the unqualified waterproof and moisture-proof performance will definitely lead to peeling, cracking, peeling and even mildew and yellowing of wall latex paint. In addition, the putty prepared on site cannot guarantee that its glue is non-toxic. Once the putty is toxic, because it is a primer material and covered with latex paint, the toxicity is not volatile, which will have a bad long-term impact on the living environment of the family.
