Fibreglass Boats

TOPSIDES AND UPPERWORKS TREATMENT

NEW SUBSTRATE: All fibreglass or plastic made boats should be thoroughly degreased with a suitable detergent and cleaned with a cloth soaked with a synthetic type thinner (e.g.Thinner 107). Then proceed with a light sanding with medium-fine abrasive paper to provide a better keying pattern for the coating system.

PREVIOUSLY COATED SURFACES. In good conditions. If the old paint is in good condition and it only needs a topcoat because it is dull, dirty or slightly powdering but with the underneath coatings still well fixed to the substrate (with no cracks or bubble), proceed with thorough cleaning and degreasing followed by suitable sanding with medium-fine abrasive paper (#180-240). Thoroughly remove dust and all sanding residuals before starting the paint application. Apply 1 to 3 coats of topcoat compatible with pre-existing paints. In poor conditions. If the old paint is in poor condition of maintenance with cracking or flaking paint, it is then necessary to completely remove the old paint with a suitable paint remover (Stripcarena), by scraping or by wet and dry sanding. Then proceed with surface preparation as described above for “NEW SUBSTRATES” and follow with the suggested coating system for fibreglass.

BOTTOM TREATMENT

NEW SUBSTRATE. Please refer to what has been already described above in “NEW SUBSTRATE” for Topsides and Upperworks.

PREVIOUSLY COATED SURFACES. In good conditions. If the bottom is in good condition it is generally enough to remove any powdering parts of the old antifouling with fine abrasive paper and apply 2 coats of new antifouling compatible with the pre-existing one. If the type of the old antifouling is not known it is recommended to apply 2-3 coats of Solver primer intermediate undercoat before applying the new antifouling. In poor conditions. If the old paint is in a poor condition with cracked or flaking paint it is necessary to remove this completely back to bare steel by scraping or by Stripcarena paint remover. (Do not use Svernigraf as it could impair the jelcoat surface). Then proceed with surface preparation as already described in NEW SUBSTRATES and follow up with the suggested coating system.
