We need to paint for a whole number of reasons. As well as decoration and appearance, painting helps protect your boat, makes it easier to clean and safer to sail. By creating a film between a substrate (surface) and the environment. paint protects:
Steel & aluminium against Corrosion
GRP against Osmosis
Wood against Rot and weathering
Underwater areas against Fouling
Decks against Abrasion
Once the surface is protected, paint can be used to enhance the appearance of your boat.
