There are certain things you must know about when choosing and making use of paints and sealants to your boat. Paints for beauty and protective purposes vary enormously based on the fabric being treated.
Among the most complex remedies have been devised to counter rusting in metal hulls. In GRP production boats with hulls coated with gelcoat, the only maintenance required outside is occasional polishing above the waterline, and cleaning and anti-fouling below. Anti-foulings are thick paints containing chemical substances toxic to marine life similar to weed and barnacles. Some leach away leaving a spongy residue which can simply be sanded off, while other newer types are ablating, which means the action of the water wears them away leaving recent toxins. The toxins are primarily organic copper, mercury or tin compounds. Some countries prohibit using certain anti-foulings, particularly in enclosed waters, so it is necessary to check your native legislation.
Fibreglass, if it is to be painted, ought to first be coated with a fibreglass primer. Wood must be sanded smooth and either varnished or primed for a colour coating. Where it is enclosed, wood should be handled with a preservative to forestall rot. For uncovered wood, a varnish containing ultra-violet filters must be used. The very best opaque paints for marine use, are the two-pack polyurethanes which are more costly than enamels, but produce a really hard film. Enamels are easier to apply, are thinned with mineral turpentine or similar, and are easier to the touch up. Polyurethanes are thinned with aromatic solvents like xylene and toluen which give off disagreeable fumes, and being -pack, must be combined in quantities which will cover the required area and used within hours.
Aluminium needs to be washed with dilute phosphoric acid, after which painted with an etch-primer before being painted with a normal chromate metal primer after which ideally a polyurethane type paint. Galvanized steel should be degreased, and then treated with dilute hydrochloric acid to etch a key for the chromate metal primer. Underwater areas, either GRP, timber or steel, ought to first be painted with a coat of epoxy. Within the case of GRP hulls, this reduces the likelihood of osmosis in which molecules of water pass by means of the gelcoat and form bubbles. Metal boats need a high quality sandblast before the anti-corrosive system is applied.
