T/CECS 10108-2020 "Polymer cement Waterproof Decorative Coatings" stipulates the technical requirements, performance standards and application specifications of polymer cement waterproof Decorative Coatings. The coating combines the advantages of polymer and cement, has good waterproofing, impermeability and decorative effect, and is widely used in building exterior, basement, swimming pool and other waterproof projects. The standard details the composition of the coating, water resistance, adhesion, crack resistance, UV resistance and other key performance indicators, and puts forward clear requirements on the construction method, film thickness, construction environment of the coating. Through the implementation of this standard, it aims to improve the mass and protective effect of polymer cement waterproof coatings, promote the application of green building materials, and promote the technological progress and sustainable development of the construction industry.
