PU30 Hybrid Polyurethane Waterproof Roof Coating

PU30 by Armourtite is a professional-grade, spray-applied hybrid polyurethane waterproof roof coating, designed in the UK to deliver long-lasting protection across a wide range of roofing applications. Developed for both new build and refurbishment projects, PU30 combines rapid installation with exceptional durability, forming a seamless waterproof membrane that performs in demanding environments.

Product Overview

PU30 is a single-component, rapid-setting coating that cures to form a highly elastic and UV-stable waterproof layer. Its seamless application eliminates joints and overlaps, reducing the risk of water ingress while providing consistent coverage over complex roof geometries. Once cured, PU30 remains vapour permeable, allowing moisture within the substrate to escape while preventing external water penetration.

Designed for professional use, PU30 is suitable for roofs subject to pedestrian traffic when correctly specified, making it ideal for communal and access areas where durability and safety are essential.
