Mastic d'étanchéité pénétrant et imperméable 100 ml – Réparation invisible des fuites pour carrelage/murs/toitures

Our waterproof adhesive (100ml) is carefully formulated with vinyl acetate copolymer and polyvinyl alcohol. This layer is specially designed for penetrating into the interior of materials, generating hydrophobicity after curing, regulating surface tension, crystallizing upon contact with water, effectively blocking leaks, and allowing water droplets to float on the surface, thereby achieving a waterproof effect. The usage method is extremely convenient: 1. Before construction, the surface of the base layer should be cleaned to ensure it is dry and free of dirt. If there are cracks (larger than 2mm), it is recommended to repair them with sealant first and then apply waterproofing agent. 2. Spray or brush this product directly onto the surfaces of tiles, floor tiles, wall tiles, cement, etc., and wait for it to penetrate the base layer. After a few minutes, when there is no liquid on the surface, spray two to three times to enhance the effect. After curing for 24 to 48 hours, a waterproof layer can be formed, and the waterproof layer will strengthen as time goes by. And it can repair leaks on the exterior walls and roofs.
