PREPARATION OF STEEL ABOVE THE WATERLINE

Cleaning

Make sure the steel surface is dry and remove all dirt, wax and other contamination.

Rust removal and sanding

The steel surface must be cleaned of rust and mill scale, preferably by sandblasting to SA 2.5. If sandblasting is not possible, sand the entire surface manually or by machine using 60-80 dry abrasive paper. All welding spots/ drops must be removed and sharp edges must be rounded with a grinder. Areas where rust removal is difficult should be prepared with a dependable rust remover.

After cleaning, removing rust and sanding, apply the first (thinned) primer coat as soon as possible to ensure the least amount of renewed oxidation. The temperature of the (bare) steel must at least be 3°C. above the dew point.

Filling

Above the waterline, fill irregularities with Epifanes Epoxy Filler. After the filler has dried, sand with 220 dry abrasive Paper and apply the first thinned primer coat.

MAINTENANCE OF PREVIOUSLY PAINTED STEEL

In order to keep a paint system in good condition, apply one or more maintenance coats periodically.

If the existing paint is still intact and only shows discolouration or loss of gloss, degrease with Epifanes Spray thinner for Paint & Varnish. Then sand and apply one or more maintenance coats. Lifting and/or damaged paint must be removed completely and replaced by a new paint system including primer coats.

One-component Epifanes Yacht Paints can be applied on almost all existing paint systems regardless of brand. Epifanes Poly-urethane Yacht Coating can be applied on existing polyurethane or epoxy based systems regardless of brand.
