Vulkem 346 – Durable, UV-Stable Top Coat for Pedestrian Waterproofing Systems
Complete your waterproofing system with a finish built to last. Vulkem 346 is a high-performance, UV-stable, single-component polyurethane top coat specifically designed to protect Vulkem base coats like Vulkem 350R from weathering, UV degradation, and pedestrian wear. As the final layer in a fully warrantied system, it provides a durable, seamless surface that is both mildew-resistant and aesthetically clean.
A key feature of Vulkem 346 is its ability to achieve custom slip ratings by broadcasting Tremco's aggregates into the wet film, making it adaptable to safety requirements for balconies, podiums, and other pedestrian areas. Tested to AS4654.1, it ensures full compliance with the National Construction Code for external waterproofing in Australia.
