MAINTENANCE
Using 100 grit sandpaper or a pumice stone, roughen the patch area on the boat as well as the backside of the patch. When sanding, you just need to rub off the protective outer surface of the fabric until a dull finish appears.
Clean the sanded surfaces with either toluene or tolual cleaning solvents. Keep solvent off skin.
ONE PART GLUE (EMERGENCY REPAIRS ONLY)
Follow the directions on the cement tube.
TWO PART ADHESIVE
Mix a batch of adhesive according to the mixing directions provided with the adhesive. Keep adhesive off skin. When the adhesive is fully mixed, it must sit for a short time to activate the catalyst. Failure to do so will create poor fabric adhesion.
Apply two thin layers of adhesive using a short bristle brush, in a circular pattern on both the backside of the patch and the patch area on the boat. Allow the first layer to dry completely (approximately 15 minutes) before applying the second layer. The second layer should dry until tacky, then apply the patch to the prepared area and press down firmly. Using a smooth object (the back of a tablespoon works well), force out any air bubbles that may have been trapped under the patch, working from the center of the patch to the outside.
After removing the masking tape, use solvent to clean up any excess glue, then place a 4 ‑ 5 pound weight onto the patch and allow 24 hours drying time before pressurizing the repaired air chamber.
