Bottom
Painting and Barrier Coating
Largest Boats in Arizona
Boats
that remain in Arizona's lakes should probably be bottom painted
every 3-5 years because fiberglass is prone to osmotic blistering
and fouling. Electrolysis is the process by which water gets
into the laminate, reacts with the resin and forms blisters,
leading to the breakdown of the laminate and cracking. Once
the gel coat is breached in this manner, the underlying laminate
is capable of absorbing water like a sponge. Fouling is a product
of changing water qualities and temperatures which produce different
types and breeds of fouling. Shells, weeds and slime are all
fouling that want to attach themselves to your boat. Once established,
they can rapidly spread or colonize the surface. Foulings add
weight to your boat and cause drag, which increases your fuel
consumption and reduces plane. Prevention is better than the
cure of having to remove the fouling by scraping. Barrier coating
seals up the laminate and fills any areas voided of resin. Anti-Fouling
provides a water barrier to prevent reoccurrence of damage.
