A cold-applied liquid coating for long-term roof protection, providing outstanding waterproofing and weatherproofing properties. This single-component, solvent-free roof coating will bond strongly to all types of roofing materials, following even complex roof contours, and will allow the surface to breathe due to its microporous structure. The applied system incorporates a reinforcement sheet to allow an easy control of the coating thickness during the application as well as adapting 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. It is certified by the BBA and has proven to provide excellent protection of roofs for in excess of 25 years.
