Section 6 Boat Maintenance
Preparation is the key to successful hull painting. If
the hull is bare, the gelcoat will have to be de-waxed
before sanding can begin. After de-waxing is com-
plete, light sanding with 80-grit sandpaper is recom-
mended.
Proper ventilation and dust collection is essential. The
dust created from sanding is toxic and should not be
breathed. A properly fitted respirator must be used.
DO NOT use a paper filter mask.
The bottom paint can be applied after sanding and
cleaning is complete. Follow the manufacturer’s rec-
ommendations for applying the paint. Always use the
etching primer called for by the paint manufacturer.
Humidity and weather will play a role in how and when
the paint is applied. Several thin layers are better than
one thick layer. Make sure there is enough paint left to
cover areas that were not accessible during painting
because of slings or jack stands.
Follow the manufacturer’s recommendations for peri-
odic maintenance after the painting is complete. If the
hull bottom is already painted, you must be sure to test
the new paint’s adhesion to the old paint. If the paints
are incompatible, the new paint will “lift” the old paint.
Never apply paint without first preparing the old
painted surface.
