Vulkem® EWS is a cold-applied, waterproofing system that utilizes polyurethane-methacrylate (PUMA) technology. PUMA waterproofing systems offer superior elongation over traditional MMA/PMMA technology systems. 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.
No. Traditional constructions solvents such as xylene, mineral spirits, acetone, isopropyl alcohol, etc cannot be used with PUMA Technology. All cleaning of tools and coating must be done with Tremco PUMA Cleaner.
No. Tremco PUMA components contain both polyurethane methacrylate and methyl methacrylate. While these ingredients carry a distinct odor, neither are harmful. In fact, the chemical makeup is almost identical to acrylics used in nail salons.
PUMA Technology can be applied down to 20 °F/ -7 °C.
Each layer of all PUMA technology systems cure in 30-45 minutes and the next coat can be applied at that time. In fact, they can be opened up to traffic one hour after installation is complete.
