550 Patch-N-Go (Self-Sealing Tapes)

550 Patch-N-Go (Self-Sealing Tape)

KARNAK 550 Patch-N-Go self-sealing tapes are composed of highly adhesive butyl rubber compounds with either a protective aluminum film or absorbent  fleece. These tapes were developed to quickly seal surfaces and stop the intrusion of moisture. The aluminum reinforced film tapes are  self-protecting making them a true “One-Step” sealant product that’s available in White, Black or Silver. The aluminum film readily accepts solvent or acrylic based coatings and paints. The Fleece tape is ideal for use with metal roofing or single-ply roof applications as a seam and detail waterproofing fabric that bonds firmly to the surface. Also use in creating seals for abutting and fastening mechanical equipment. Offers a high degree of vibration dampening. May also be molded to shape for custom sealing. The highly adhesive bond of 550 Patch-N-Go stays flexible in a wide range of temperatures for service use in all climates.

All surfaces to be sealed should be dry, smooth, clean and free from dirt, dust, oxidized carbon dust, loose paint or coatings, oil, grease, rust, or other foreign matter. Clean single ply membrane surfaces with toluene, xylene, acetone or single ply manufacturer’s primer or splice wash. Clean metal with  similar solvent or TSP substitute and water. Follow instructions and SDS safety precautions of primer, wash or solvent manufacturer carefully when  using.

After surface has been properly prepared, cut desired length of 550 Patch-N-Go. Remove silicone release liner and position over desired area. Apply the  tape directly to the area exactly the first time. Trying to remove may damage the tape and roofing surface. Press down firmly with a cloth pad, finger  pressure or roller making sure tape stays conforming to the roof surface as you smooth out on to the surface. Edges should be free of fishmouths and  tunnels. 550 Patch-N-Go White, Black or Silver may be coated over the same day, if desired. 550 Patch-N-Go Fleece should be coated over immediately.
