Jaysuing Lot de 3 Colle invisible pénétrante, imperméable et résistante à l'humidité pour carrelage de salle de bain, murs extérieurs et fuites de toiture

Our 3-pack waterproof glue contains ethylene-vinyl-acetate copolymer and polyvinyl alcohol.It can penetrate into the interior of the material.After curing, it can produce hydrophobicity, adjust surface tension, and crystallize when exposed to water.It can effectively seal leaks, causing water droplets to float on the surface, thereby achieving a waterproof layer effect.Its usage method is very simple: 1Before construction, the base surface should be cleaned to ensure it is dry and free of dirt.If the crack is larger than 2mm, it is recommended to first use sealant to repair it, then use waterproofing agent.2.Spray or apply this product directly onto ceramic tiles, floor tiles, wall tiles, cement, etc., and wait for it to penetrate into the base layer.After a few minutes, when there is no liquid left on the surface, spray two to three times to enhance the effect.After curing for 24-48 hours, a waterproof layer can be formed, and the waterproof layer will strengthen over time.And it can repair leaks in exterior walls and roofs.
