The DB 44/T 1087-2012 standard specifies the technical requirements for interior-wall Inorganic Coatings, which are suitable for painting on interior walls of buildings. The standard details the raw materials, formulations, construction processes and coating performance requirements of Inorganic Coatings, covering indicators such as water resistance, stain resistance, antimicrobial resistance and environmental friendliness of Coatings. Inorganic Coatings are widely used in interior walls due to their excellent vapor transmission rate and low pollution characteristics, especially for spaces requiring high air mass and environmental protection standards. By implementing this standard, we can ensure the use effect and mass stability of Coatings, improve the comfort and health of the indoor environment, and promote the application and development of Inorganic Coatings in architectural decoration.
