About the product Our invisible waterproofing agent contains polymer copolymer. It is waterproof and moisture-proof and easy to apply. Its usage is very simple: 1. Clean the base surface before application and make sure the base surface is dry and free of dirt. If there are cracks (more than 2 mm), it is recommended to repair them with sealant first and then apply waterproofing agent. 2.

A waterproof layer can be formed after curing for 24-48 hours, and the strength of the waterproof layer will be stronger with time. And a layer of insoluble waterproof polymer compound with a thickness of several molecules can be formed on the surface and inside of the structural material. This resin film has the advantages of waterproof, anti-seepage, moisture-proof, rust-proof, and pollution-resistant.
