Description
SRS PU Fast
Fast-Drying Aliphatic Polyurethane Waterproof Coating for Roofs
SRS PU FAST is a fast-drying, one-component, water-based aliphatic polyurethane waterproofing coating designed specifically for roofs. PU Fast dries rapidly, allowing for recoating in just 2 hours, and facilitates the full completion of the waterproofing system in a single day. It demonstrates resistance to rain within just 30 minutes of application. The coating forms an impermeable membrane that provides high resistance to UV radiation and mechanical stress.
Fields of Application
