M-1 is a moisture cure, multi-purpose structural adhesive/sealant designed for bonding and sealing a wide range of construction materials. M-1 forms a tough elastic waterproof seal to most roofing materials, masonry, wood, glass, aluminum and foam. M-1 bonds well to most building surfaces including: metal flashing, copings, skylights, and HVAC surfaces.
Bonding surfaces should be clean, dry and free from all contamination that may inhibit the sealant’s performance. Isopropyl alcohol is an effective cleaner for surface preparation. Install all joint applications per ASTM and SWRI recommendations and guidelines. Please contact customer service for application guidelines for temperatures below 32 degrees F (0 degrees C). Maintain sealant at room temperature before application to ensure adequate tooling and adhesion. This product sets rapidly upon exposure to moisture.
