REPAIRS
Small tears and punctures in the air chambers that are 1 cm
(0.393 in.) or less, can be repaired in an emergency. Larger
areas, or if the patch will overlap a seam, should be patched by a
professional repair technician at an inflatable repair station.
Contact your local Mercury dealer for the nearest inflatable repair
station.
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 the boat should not be in
direct sunlight.
Cut out a patch large enough to overlap the damaged area by a
minimum of 38 mm (1.5 in.) from 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.
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. Do not allow solvent to contact your 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. 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 allow sufficient time will
create poor fabric adhesion.
