Product Overview

The Everbuild Aquaseal Liquid Roof Membrane Coating in Slate Grey (21kg Trade Tub) is a professional-grade, fast-curing waterproofing solution ideal for both flat and pitched roofs. Designed for durability and ease of use, this single-component polyurethane-based liquid coating forms a flexible, seamless membrane that delivers long-lasting protection against water ingress and weather damage.

Suitable for use on new installations, extensions, or to refurbish failing roofs, this coating offers a cost-effective, high-performance alternative to traditional roofing systems. The 21kg trade tub provides excellent value for contractors, making it ideal for large-scale roofing projects or ongoing maintenance work.
