Engineered for strong adhesion, fast curing, and high flexibility, XtremeCoat forms a seamless, elastomeric membrane that helps protect against water intrusion, UV exposure, and environmental stress.
This advanced coating is formulated to bond to a wide range of substrates, including concrete, metal, modified bitumen, SPF foam, PVC, TPO, EPDM, plywood, and existing roofing systems. Its ability to adhere to damp and properly prepared surfaces makes it especially valuable for restoration and maintenance projects where downtime must be minimized.
Once cured, XtremeCoat creates a durable, weather-resistant barrier with excellent elongation and crack-bridging capability, allowing it to accommodate normal structural movement without compromising waterproof integrity. It is commonly used in commercial roofing systems, waterproofing applications, water containment structures, and below-grade protection projects.
