Our transparent waterproof adhesive contains defoamers and polyurethane resin. It can provide lasting and long-lasting protection against water damage. Its usage method is very simple: Clean the construction surface to ensure it is free of moisture. Use a brush to evenly apply the invisible waterproof glue to the construction area and wait for 24 hours for it to dry. And it can quickly form a dense protective layer, effectively repairing and sealing the damaged surface to prevent water penetration.
