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 trace the outline of
the patch with a pencil. 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
methyl ethel ketone patching solvent and cleaner. Do not allow the solvent to
contact your 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. Do not allow the adhesive to contact your 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.
