Description

AWF PRO Modified Rubber Roof Coating is a professional-grade, single-component SEBS thermoplastic mastic designed to seal, protect, and reinforce critical roofing details. Engineered for durability and flexibility, this high-performance coating forms a seamless, waterproof barrier over seams, penetrations, fasteners, and flashing areas where leaks are most likely to occur.

Formulated for compatibility across a wide range of roofing substrates—including metal, EPDM, TPO, APP, Hypalon, and wood—this modified rubber mastic delivers excellent adhesion, elongation, and UV resistance. Its thick, brushable consistency makes it ideal for both targeted repairs and preventative maintenance, helping extend the life of roofing systems in demanding environments.

 

Features & Benefits

  • High Solids, Flashing-Grade Formula: Thick, high-build consistency designed to fill gaps, cracks, and joints while reinforcing vulnerable roof areas.
  • Stops Leaks & Prevents Water Intrusion: Creates a seamless, waterproof seal over problem areas including seams, penetrations, and fasteners.
  • Excellent Adhesion to Multiple Substrates: Bonds to metal, TPO, PVC, EPDM, modified bitumen, BUR, and other common roofing materials.
  • UV & Weather Resistant Performance: Resists sun exposure, ponding water, and extreme temperatures without cracking, shrinking, or degrading.
  • Flexible & Durable: Maintains elasticity over time, allowing movement with the roof and preventing future failures.
  • Low VOC, Contractor-Friendly Formula: Designed for professional use with reduced odor and easier application compliance.
  • Ideal for Repairs & Maintenance: Perfect for extending roof life, handling emergency leaks, and reinforcing high-risk areas.
