Invisible Waterproof Agent 300G Transparent Repairing Leak Waterproof Adhesive for Roofs, Walls, Bathroom, Shower, Window Sills, Indoor & Outdoor Water Proof Coating

A water-based transparent waterproof sealant. Its water-rubber formula penetrates and seals cracks, joints, and leak points. Once cured, it forms a dense, crystal-clear waterproof layer — virtually invisible to the eye. How to Use: ① Clean the surface — ensure it is dry, dust-free, and free of oil or debris. For cracks wider than 2mm, fill with caulk first. ② Apply the first coat evenly using a brush or roller. Allow the product to penetrate into the base material. Prohibited Use Cases - Not recommended for long-term load-bearing structures. - Not recommended for use on soft silicone, PE, or PP materials. - Not recommended for surfaces in contact with food. - Not recommended for use inside high-pressure oil lines or fuel tanks (external repairs are permissible). ③ Once the surface appears dry, apply 2-3 additional coats in a cross direction. Allow each coat to dry before the next. ④ Allow 24-48 hours to fully cure. Cold or humid conditions may extend curing time. Avoid water contact until fully cured.
