Fibreglass painting systems - Skipper's Line Marine coatings systems

Surface Preparation for - Bare GRP

All fibreglass substrates should be thoroughly degreased and cleaned, to remove traces of mould release agents that may be present with a suitable surface cleaner. The surface should then be lightly sanded with medium to -fine abrasive paper to provide a keying pattern for the subsequent coatings, the substrate should then be thoroughly wiped to remove any dust.

Previously coated surfaces - Topsides

If the existing coating is in good condition and adhesion is still good, proceed with thoroughly degreasing and cleaning the existing coating followed by sanding with medium -fine abrasive paper (180-240). Thoroughly remove all dust and sanding residuals before starting the paint application. Apply undercoat and topcoat as required.

If the existing coating is in poor condition, cracking or flaking paint, then it is necessary to remove the old paint with either a remover Stripcarena or by scraping or sanding. And then proceed with the preparation as described for bare substrates.

Previously coated surfaces - Below the waterline

If the existing coating is in good condition, it is generally enough to remove any powdering or loose parts of the old antifouling, by sanding with a fine abrasive paper and applying 2 coats of the new antifouling compatible with the existing one. if the type of antifouling is unknown it is recommended to apply 2-3 coats of solver primer intermediate undercoat before applying the new antifouling.

If the existing coating is in poor condition, cracking flaking and loss of adhesion from substrate it is necessary to remove the old antifouling with a suitable antifouling remover Stripcarena or by sanding with medium abrasive paper, thoroughly remove all dust from the substrate. Then proceed with preparation as described for bare substrates.
