11. Maintenance
11.1 GRP-maintenance and repair:
Maintenance:
Should the gelcoat finish appear dull or the colour faded, the original finish
can be restored using an abrasive paste. If necessary sand the surface
beforehand, finishing with a fine wet and dry sandpaper of grade 400 or
finer. After sanding the surface must be waxed and polished. Polishing can
be done by hand or with a rotary polisher. Waxing should always be
undertaken by hand.
Fading can be reduced through regular waxing and polishing biannually after
first cleaning the surface. Due to constant exposure to sunlight and exhaust
gasses fading can however not be totally excluded.
Tip:
If the surface is coated with a single pack clear varnish (wood varnish) after
grinding (without wax or polish) it will be protected for a far longer time.
Orange-based colours are particularly susceptible to sunlight; therefore
painting of the surface may be necessary if polishing does not work.
Preferably a 2 component coloured paint is to be used. Grind and prepare
the surface according to the paint suppliers instructions.
Note:
All types of grinding reduce the thickness of the gelcoat. If the
gelcoat is partly removed, a new coating is necessary for
protection.
Gelcoat repairs:
Small gelcoat damages or hairline cracks can’t be avoided during general
handling of the rescue boat. They do not have an effect on the strength of
the boat, and are therefore, excluded from the guarantee. However, to avoid
the ingress of water, such areas should be sandpapered and covered with
fresh gelcoat, clear varnish or paint. Deeper scratches may require the use
of a filler before hand.
The standard gelcoat colours are:
orange: similar to RAL 2004
