Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and marking for spray polyurea waterproofing coatings. It is applied in the construction industry for waterproofing of roofs, underground structures, tunnels, bridges, and other concrete or steel surfaces where rapid-curing, high-elasticity, and durable waterproofing is required. The standard ensures consistent performance in both new construction and repair projects, particularly in environments demanding strong adhesion and resistance to chemicals or abrasion.
