Waterproofing
Polyurethane SystemsTransparent Waterproofing System
Clear waterproofing technology — protecting tiled surfaces without changing their appearance.
Overview
A transparent polyurethane waterproofing system for open-air exposed areas — balconies, terraces, patios, and walkways — where preserving the appearance of existing ceramic tiles is the priority. Addresses cracks in mortar joints caused by constant temperature changes and prevents water ingress through existing tile surfaces without the cost and disruption of tile removal and replacement. The clear membrane provides long-term crack-bridging protection, invisible to the eye.
