T/SCDA 018-2018 "PTS waterproof coatings system building structure" introduction T/SCDA 018-2018 is a group standard issued by the Shanghai Construction Association, which stipulates the application technical requirements of PTS waterproof coatings system in building structure. The standard is applicable to the waterproof engineering of roofs, basements, kitchens, toilets and other building parts, and specifies the performance indicators of waterproof coatings, such as fracture elongation ≥ 500%, bond strength ≥ 1.0MPa, and water impermeability 0.3MPa (120 minutes impermeable). The standard also provides detailed structural design, construction technology and mass acceptance requirements, aiming to standardize the application of PTS waterproof coatings system and improve the mass and Reliability of building waterproof engineering.
