Pedestrian (PUMA) Traffic Coating
Brand: Tremco Incorporated
Vulkem® EWS with PUMA Technology is designed to have tenacious adhesion and extreme abrasion resistance. It can be walked on in one hour, which will minimize operation disruption. Vulkem Extreme Wearing System (EWS) is a waterproof traffic deck coating system that utilizes polyurethane- methacrylate (PUMA) technology. Vulkem EWS is composed of a primer (Tremco PUMA Primer), a base coat (Tremco PUMA BC), and a top coat (Tremco PUMA TC). All system components are cured using Tremco PUMA Initiator.
Features- Vulkem EWS is a cold-applied traffic deck coating system designed for waterproofing concrete slabs and protecting occupied areas underneath from water damage.
- Additionally, the system will protect the concrete from the damaging effects of chloride, deicing salts, chemicals, gasoline, oils and anti- freeze.
- The Pedestrian System is ideal for stadiums, balconies and pool decks.
- PUMA technology delivers extreme durability while maintaining its crack-bridging characteristics, eliminating the need for reinforcing fabric
- Rapid set-up times allow for quick overall installation, as well as the ability to open up to traffic one hour later
- Can be applied at temperatures as low as 14 °F (-10 °C), which allows for continuation of projects in the colder months
- Initiator adjustments allow for 30 to 45 min cure time between applications, even at temperatures below freezing
- Extremely forgiving application allows users to apply additional coats long after the previous coat has cured
- Unique chemistry allows for easy repair
- Compatible with Tremco sealants, coatings and expansion joints, which is essential for tie-ins, detailing and penetrations
