polymer Modified Asphalt Coating For Roof Waterproofing
Product Description
Liquid waterproof membrane is a single-component, high-elasticity water-based modified asphalt polymer coating. Made of modified asphalt and acrylic polymer materials, it is ready-to-use without heating. After construction, it forms a seamless, flexible and fully bonded waterproof film. It replaces traditional sheet membranes, eliminating leakage risks caused by overlapping joints.

Product Features
- Seamless integral waterproofing – No overlapping joints, zero hidden leakage points.
- High elasticity & crack bridging – Strong flexibility to cover substrate micro-cracks and structural deformation.
- Water-based & eco-friendly – Non-toxic, odorless, flameless cold construction, safe for indoor and outdoor use.
- Strong adhesion – Firmly bonds to concrete, cement mortar, metal and old waterproof layers.
- Excellent weather resistance – Anti-aging, heat and low-temperature resistant, suitable for long-term exposed use.
- Easy & fast construction – Can be rolled, brushed or sprayed, perfect for irregular shapes and details.
- Damp surface applicable – Allows construction on damp substrates without standing water.
Usage Method
- Surface preparation – Clean dust, oil and loose parts. Repair cracks and chamfer corners and pipe roots.
- Priming treatment – Apply diluted primer coat on rough surfaces for better penetration.
- Multi-layer coating – Apply 2–3 coats in cross direction. Ensure each layer is dry before next application.
- Reinforcement – Use polyester fabric at cracks, corners and joints for enhanced waterproofing.
- Curing – Allow full curing before putting into service. Do not construct in rain or standing water.
