For the best results when gluing, the relative humidity should be
less than 60%, ambient air temperature should be between
18 °C to 25 °C (65 °F to 77 °F) and not in direct sunlight.
Cut out a patch large enough to overlap the damaged area by
38 mm (1.5 in.) on all sides. Center the patch over the damaged
area, and with a pencil trace the outline of the patch. Apply masking
tape around the perimeter of the outlined patch area to ensure a
tight and clean glue line.
Clean the patch area on the boat as well as the backside of the
patch with M.E.K. (methyl ethel ketone) patching solvent and
cleaner. Keep solvent off skin. After applying the solvent, you will
notice that the area will become tacky. This tackiness ensures
good glue adhesion.
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 two part 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 three thin layers of adhesive with a short bristle brush, in a
circular pattern on both the backside of the patch and the patch
area on the boat. Allow each layer to dry for 5‑10 minutes before
applying the next layer. After applying the third layer, wait 5‑10
minutes and then apply the patch to the prepared area and press
down firmly. Using a smooth object (a 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, place a 4‑5 pound weight onto
the patch and allow 24 hours drying time before pressurizing the
repaired air chamber.
