Prep: All surfaces should be dry, smooth, clean and free from dirt,
dust, carbon dust, loose paint or coatings, oil, grease, rust or
other foreign matter. Treat the surface as directed below for the
appropriate substrate:

  • Single-Ply Membranes – Clean with toluene, xylene or acetone
  • Metal Panel – Clean with high pressure water or a water TSP solution as needed. Remove all rust with a wire brush.
  • Asphalt surface – Clean with high pressure water
  • Silicone – Do not apply over silicone coatings


Apply FT 500 Butyl Fleece Tape only in temperatures between 40°F and 105°F. After the surface has been properly prepared, cut tape to desired length. Remove the release liner and position tape over desired area. Precisely apply the tape directly to the area on the first attempt as trying to remove tape may damage the tape and/or the roofing surface. Firmly press on all areas of tape with a finger or roller making sure tape stays conformed to the roof surface. Always roll from the center towards the outside to remove any air pockets. Edges must be free of any fishmouths. Do not stretch tape during application. Apply PM silicone coating over tape the same day.
