DBJ/T 01 57-2001 "Technical Regulations for the Application of Building exterior resilience Coatings" aims to standardize the production and construction of building exterior resilience Coatings to ensure that their technology is advanced, economical and reasonable, safe and applicable, and to ensure the mass of the project. This regulation is applicable to the construction and acceptance of exterior body Coatings on concrete, block, brick walls and cementitious mortar and polymer cementitious mortar surfaces. Coating product mass must meet the requirements of this standard and comply with relevant national and local standards and codes. This procedure refers to a series of standards, including film drying time, water resistance, scrub resistance and other test methods to ensure the performance and durability of Coatings products.
