Our invisible water repellent contains polymer copolymers. It can be waterproof and moisture-proof, convenient construction. Its use method is simple: 1. Clean the base surface before construction to ensure that the base surface is dry and free of dirt. If there are cracks (more than 2 mm), it is recommended to repair with sealant and then use waterproofing agent. 2.

A waterproof layer can be formed after 24-48 hours of curing, and with the extension of time, the strength of the waterproof layer will be stronger. And can form a layer of several molecular thickness of insoluble waterproof polymer compounds on the surface and inside the structural material, this resin film has the advantages of waterproof, impermeable, moisture-proof, rust-proof, pollution resistance and so on.
