Polymer Modified Asphalt Leak Repair Bituminous Waterproofing Coating High Elasticity

High-elasticity Polymer Modified Asphalt Leak Repair Waterproof Coating

Product Introduction

Liquid membrane waterproof coating is one‑component water‑based polymer modified‑asphalt waterproof material, formulated with high‑quality emulsified asphalt, polymer and functional additives, ready‑to‑use out of bucket. After brushing, rolling or spraying, it cures at ambient temperature into seamless, rubber‑like elastic waterproof film. It combines easy application of liquid coating and high crack‑resistance of sheet membrane. It can be used as independent waterproof layer or compounded with asphalt membranes for composite waterproofing system, widely used for non‑exposed projects and old roof leak repair.

Product Features

1. Seamless monolithic waterproofing: Liquid‑formed without lap joints, fits complex details such as corners, pipe bases and gutters, avoids leakage risks at overlaps.
2. High elasticity & self‑healing: High film elongation to accommodate micro‑cracks caused by substrate settlement and thermal movement, with creep self‑repair performance.
3. Strong adhesion: Excellent bonding to concrete, cement mortar and old asphalt membranes, suitable for new and old substrates.
4. Easy cold‑applied construction: One‑component ready‑to‑use material, multiple application methods: brush, roller, spray. Fire‑safe and high‑efficiency.
5. Water & chemical resistance: Cured film resists long‑term water immersion and acid‑alkali, stable at varied temperature, durable for underground and damp conditions.
6. Good compatibility: Compatible with SBS, self‑adhesive and other asphalt membranes for “coating‑membrane” composite waterproofing.
7. Water‑based & eco‑friendly: Low‑odor water‑based formula, free of coal‑tar hazardous substances.

Application Scope

1. Non‑exposed waterproofing and leak repair for new & old concrete roofs, gutters and balconies.
2. Waterproof & damp‑proof for basement slab, side wall, underground garage, water tank and canal.
3. Reinforced sealing for pipe roots, corners and construction joints.
4. Renovation & repair for old membrane roofs, directly coat over existing asphalt membranes.
5. Waterproofing for hot‑work‑forbidden projects and irregular‑shaped structures.
