Description

A single component liquid made up from pure polyurethane, which once catalyzed, forms a continuous elastic membrane without any joints, overlapping or any integrated mesh needs. Its properties make it an excellent choice for achieving air-tightness and perfect waterproofing on a multitude of surfaces and substrates. It is applied manually, using a roller or brush and, exceptionally, using specific spray equipment.


Widespread systems:

23 thin layers by roll or brush to achieve the recommended thickness/ Single layer to achieve the recommended thickness.
