A heavy duty waterproofing system based polyurethane modified methacrylates.

The Dura-Coat cold applied liquid waterproofing system provides a fast curing elastic solution for a wide range of applications.

Based on unique polyurethane modified methyl-methacrylate (MMA) resins allows for quick installation in as little as 30 minutes, even in temperatures as low as 0°C.

This highly versatile system is suitable for use on a wide variety of decks including concrete, asphalt, metal, wood and existing liquid applied systems.

System components:

Dura-Coat Membrane.
Dura-Coat Membrane Thix.
Dura-Coat Coloured Topcoat.
Dura-Systems Catalyst.
Dura-Systems Cleaner.
Dura-systems Grip Polyester Soft.
