DESCRIPTION: M1 is a multi-purpose structural sealant designed for difficult bonding and sealing applications. Its ideal as a cut edge / seam sealant on EPDM, TPO and other roofing membranes. It bonds aggressively to EPDM, PVC, BUR, coal tar, SBS modified bitumen, granulated APP, asphalt shingles, many types of coated metal, metal flashing details and window glass. For TPO roofing, use TPO Primer together with M1 sealant.

M-1 is excellent for underwater or below grade repairs. M-1 can be used for emergency repairs of pools, ponds and flat roof repairs. M-1 is a non-slumping, self-fixturing mastic that cures with a tough durable rubber bond using atmospheric moisture.

M1 develops a high 45 Shore-A hardness, 380 lbs. per square inch of shear strength on metal, masonry and wood. It has 290% elongation and can accommodate dimensional changes in construction materials down to minus 20 degrees F, and is solvent free.
