Key performance parameters and testing methods of interior wall water-resistant putty
Interior wall water-resistant putty is a kind of building material used for interior wall decoration and repair. It is mainly composed of polymers, أصباغ, fillers and additives. The interior wall water-resistant putty has excellent waterproof performance and durability, which can effectively repair and smooth the cracks and unevenness of the interior wall surface, making the wall more smooth, beautiful and durable. The characteristics of inner wall water-resistant putty include easy construction, quick drying, strong adhesion, not easy to crack and crack, and good water resistance. It is widely used in the interior wall decoration and maintenance of residential, commercial and industrial buildings, and is a very practical interior decoration material.
