Spray-type polyurea waterproof coating
This product is strictly forbidden to swallow. Gloves, goggles, filter masks, protective clothing, and masks should be worn during construction to avoid contact with the eyes and skin. This product should be kept out of reach of children. If it touches the skin, wipe it off with a clean cloth, scrub it with methyl ethyl ketone, and then rinse it with water; if it comes into contact with the eyes, wipe it off immediately, rinse it with plenty of water, and send it to the hospital for treatment. It is strictly forbidden to dispose of paint in sewers, rivers, and other places
Construction technology of SBS and APP waterproof membrane
1. Technological process: clean the base layer → apply primer oil → additional layer → lay the coiled material → detail treatment → heat-melt edge sealing → protective layer.
