The DB44/T 1087-2012 interior-wall Inorganic Coatings standard specifies requirements, test methods and application techniques for interior-wall Inorganic Coatings used in buildings. The standard applies to coatings with inorganic materials as binders, mainly for interior wall decoration and protection. Coatings must have excellent water resistance, weathering resistance, stain resistance and good adhesion, and coatings must have good vapor transmission rate and mildew resistance to ensure the use effect in various environments. The standard describes the composition, performance index, inspection method and construction process of coatings in detail, providing a basis for the production, testing and application of Inorganic Coatings to ensure the mass and safety of coating products. The standard has important guiding significance for the development, quality control and market application of interior-wall Inorganic Coatings
