Products / GacoRoof GRT50 RoofTape

GacoRoof GRT50 RoofTape is a fleece-backed self-adhesive seam tape of lightly cross-linked butyl and EPDM rubber polymers. It seals seams, fasteners, edge transitions, small cracks, vents, and drains before application of GacoRoof 100% silicone roof coating, and must be coated with a GacoFlex silicone coating rather than left exposed. It is 30 mils thick and supplied in 2-inch by 50-foot rolls.
