ARDEX WPM 426 for High-Performance Deck Waterproofing

ARDEX WPM 426 Deck Coating is a heavy-duty, two-component polyurethane waterproofing membrane designed for exposed decks, walkways, podiums, and helipads requiring long-lasting protection. It forms a seamless, flexible barrier that resists cracking, abrasion, and chemical exposure while accommodating structural movement. With high solids content and strong tensile performance, it delivers durable traffic-grade waterproofing suitable for commercial and industrial environments. The coating cures into an elastic, weather-resistant layer that withstands heat, UV, and repeated load cycles. Its trowel-applied system ensures uniform coverage, and anti-slip textures can be added for safety. Compatible with ARDEX topcoats, WPM 426 provides a complete, reliable deck-protection system.
