GB/T 9779-2015 "Multilayer Architectural Coatings" applies to multilayer architectural coatings used for interior and exterior walls of buildings with substrates such as cement-based materials. It specifies product classification, technical requirements, and test methods. The washability of coatings is tested using a washability tester, gloss is measured with a gloss meter, and the content of harmful substances such as VOC is detected using a gas chromatograph. Additionally, properties such as coating adhesion and weather resistance are evaluated. The standard defines inspection rules and acceptance requirements to ensure the decorative effect and durability of multilayer architectural coatings in use.
