Our Stealth Waterproofing Agents Contain Polymer Copolymers. It Can Be Waterproof And Moisture-Proof, Convenient Construction. Its Use Method Is Very Simple: 1. Clean The Base Surface Before Construction To Ensure That The Base Surface Is Dry And Free Of Dirt. If There Is A Crack (More Than 2Mm), It Is Recommended To Repair It With Sealant Before Using Waterproof Agent. 2. Spray Or Brush Products Are Directly Applied To The Surface Of Ceramic Tiles, Floor Tiles, Wall Tiles, Cement And Other Surfaces &Quot;Waiting For The Product To Penetrate Into The Grass-Roots Level. After A Few Minutes Of Food, Energy, And Water: When There Is No Liquid On The Surface, Spray Twice Or Three Times To Enhance The Effect. After Curing For 24-48 Hours, The Waterproof Layer Can Be Formed, And With The Extension Of Time, The Strength Of The Waterproof Layer Will Be Stronger. And It Can Form A Layer Of Insoluble Waterproof Polymer Compound With A Thickness Of Several Molecules On The Surface And Inside Of The Structural Material. This Resin Film Has The Advantages Of Waterproof, Impermeable, Moisture-Proof, Rust-Proof, And Pollution Resistance.
