In terms of function, exterior wall coatings have the functions of waterproofing, heat insulation, and heat preservation, and consumers can choose according to the style, form, and needs of self-built houses.

Consumers are advised to use exterior wall insulation paints. The coating has the functions of waterproof, impermeable, thermal insulation and heat preservation, and protects the exterior wall of the building around the clock. At present, many small high-rise buildings due to the principle of cement shrinkage or improper construction, resulting in cracks in the exterior wall, leakage in rainy weather, winter will accelerate the loss of temperature in the house, ceramic tiles can not solve this problem, and the exterior wall insulation coating produced by Rui Peim can be perfectly solved, is the current market high-rise building exterior wall decoration special coating.
