Belzona 3111 (Flexible Membrane) roof protection

Product Description

A cold-applied liquid coating for long-term roof protection, providing outstanding waterproofing and weatherproofing properties. This single-component, water-based roof coating bonds strongly to all types of roofing materials, following even complex roof contours, and allows the surface to breathe due to its microporous structure. Incorporates a reinforcement sheet to allow easy control of coating thickness and adapts to roof movement due to its outstanding elasticity.

This water-based material can be applied on almost any location including schools, hospitals and public buildings thanks to its low odour. Certified by Energy Star and ETA-Danmark (European Technical Assessment) — proven to provide excellent protection for over 25 years.
