Mount bathroom fixtures in your home, add signage to the exterior of a commercial building or deck-out your car with the flashiest LED lights. It adheres firmly in minutes and becomes 100% bonded within 72 hours. Because it is particularly capable of providing a smooth, quiet and durable ride on the open road, it is the preferred automotive double sided tape for specialty vehicles. Easy Installation: 10% strength of bond in 0.5 hours 40% strength of bond in 12 hours. 80% strength of bond in 24 hours. 100% strength of bond after 72 hours. Application Guide: 1· Surface Cleaning: Quick pre-clean of tough spots if necessary. Wet cloth to remove most contaminants. Final wipe with dry cloth. 2· Priming the Surface: Primer on a disposable towel, followed by a dry towel. Dauber bottle followed by a dry towel. Foam brush. 3· Abrading Your Substrate: Light abrasion by hand. Clean the substrate after abrading to make sure all sanding debris is removed from the bond area. 4· Tape Application by Hand: Start the tape at the edge of the surface and lay it down, applying constant pressure as you go. Apply a roll down force of at least 15 lbs with a dense J-roller over the entire area to ensure good contact between the tape and the first substrate surface. Remove the protective liner to apply the other substrate. 5· Applying Final Pressure: Applying pressure to the applied tape facilitates optimal wet-out onto the substrate.
