United Coatings Roof Mate Butter Grade Flashing

Provides increased tensile strength and elongation on problem roof areas

United Coatings Roof Mate Butter Grade Flashing is a water-based high solids acrylic sealant utilizing the latest advances in acrylic technology. Its thick, buttery consistency allows it to be easily worked into vertical seams on metal roofs, into gaps in flashings, around protrusions, and into heavily alligatored areas in weathered asphaltic roofing.

  • High-volume solids... For low shrinkage without the use of plasticizers

  • Saves time... Dries twice as fast as a coating

  • Versatile... Suited for sealing mechanical fasteners and horizontal seams on metal roofs, as well as around flashings, drains, and protrusions

  • Excellent adhesion... Adheres to asphaltic roofing, metal, concrete, wood, Hypalon®, TPO, PVC, and polyurethane foam

  • Handy... Can also be used for encapsulating United Coatings Roof Mate Fabric
