The DBJ50/T 202-2014 standard is a technical specification for the application of inorganic dry powder architectural coatings, providing the requirements for the use of this type of Coatings, construction methods and quality control measures. The standard specifies the composition, construction process, surface preparation, coating performance and test methods of Coatings for the practical application of inorganic dry powder Coatings in the construction field. The accompanying provisions help to understand and execute the standard requirements to ensure that Coatings have excellent weathering resistance, corrosion resistance and anti-pollution ability in various built environments. Through the implementation of this regulation, the application mass and construction effect of inorganic dry powder Coatings can be improved, and the standardization development of the architectural coatings industry can be promoted.
