4/13/2023 0 Comments Wall putty formula pdfCement is a binder that is good in adhesion, durable and cost-effective, but has poor tensile strength and crack resistance. The most commonly used binders for putty are cement and organic polymers, and organic polymers are also divided into emulsions and latex powders. It is the most important component of putty and mainly plays various roles such as bonding. Putty is generally composed of base materials, fillers, water and additives. However, during the construction, it is necessary to apply a layer of interfacial agent on the base layer to seal the base layer and improve the adhesion of the wall surface, so that the putty can be better bonded to the base surface. Usually the putty is gypsum or cement based, so that the surface roughness is easier to bond firmly. The internal wall putty comprehensive index is good, healthy and environmentally friendly, so the inner wall is not used externally, and the outer wall is not used internally. The outer wall putty should resist the wind and the sun, so the glue is large, the strength is high, and the environmental protection index is slightly lower. The putty is divided into two types: the inner wall and the outer wall.
