PUMA BC Cold-Applied Waterproofing System - 6 Gallon Pail

About this product

Tremco PUMA BC is a modified polyurethane-methacrylate (PUMA) base coat Tremco PUMA BC is commonly used as the waterproofing membrane in buried structures and as the base coat in traffic coating situations. Tremco PUMA BC can be used to protect concrete from the damaging effects of chloride, deicing salts, chemicals, gasoline, oils and anti-freeze. It is a two-part, chemical-curing PUMA modified coating used as an elastomeric, waterproofing membrane for Vulkem EWS and TREMproof PUMA. Tremco PUMA BC bonds firmly to Tremco PUMA Primer. It retains its integrity even if substrate movement causes hair-line cracks of up to 1/16" (1.5 mm). If cut or damaged, Tremco PUMA BC will prevent water migration between itself and the substrate. Tremco PUMA BC requires the use of Tremco PUMA Initiator for the cure. Polyurethane-methacrylate (PUMA) technology delivers extreme durability while maintaining its crack-bridging characteristics Rapid set-up times allow for quick overall installation, as well as the ability to open up to foot traffic one hour later Can be applied at temperatures below 20 锟紽, which allows for the continuation of projects in the colder months Initiator adjustments allow for 30 to 45 min cure time between treatments, even at temperatures below freezing Compatible with Tremco sealants and coatings, which is essential for tie-ins, detailing and penetrations Extremely forgiving formula allows users to apply additional coats long after the previous coat has cured Unique chemistry allows for easy repair.
