Hempel Epoxy Filler - 130ml

Hempel’s Epoxy Filler 35253 is a two-component, solvent-free marine filler for repairing cracks, fissures and small imperfections in glass fibre, hardwood, steel and other rigid materials. It can be applied in layers up to 5mm thick and is suitable for interior and exterior use above and below the waterline.

Hempel’s Epoxy Filler 35253 is a two-component epoxy filling compound developed for local marine repairs and surface preparation. It is suitable for smoothing imperfections, repairing minor pinholes in welds, filling cavities in propellers and keels, and repairing osmosis damage in glass fibre hulls.

Suitable for properly prepared glass fibre, hardwood, steel and other rigid materials, the filler can be used on interior and exterior surfaces above and below the waterline. Uncoated surfaces should be sanded, cleared of dust and primed with one or two coats of the specified Hempel primer. Previously coated surfaces should be abraded, cleaned and dried before application.

Mix Base 35259 and Curing Agent 95250 in equal parts by volume immediately before use. Mix until a uniform colour is achieved while avoiding trapped air, then apply using a putty knife or spatula. The product must not be thinned and can be applied in layers up to 5mm thick.

Once dry, sand the repaired area smooth and apply two coats of the recommended Hempel primer. Topcoat finishes must not be applied directly over the filler. Use a single-component primer where the subsequent topcoat is a single-pack coating.
