Paint requirements guide only


In general before applying new antifoul paint.

-wear all required safety gear, make sure work area is safe and boat correctly set up for work. Read product labels before use.

-high pressure clean after removal from water to clean off all build up

-remove any loose paint off the boat and make sure area is sound, then as in this case above we fully re primed with underwater primer 2 coats. Due to wear.

-apply 2-3 coats of antifoul. Hempel Olympic will stick to most other antifouls. If old antifoul is still in good condition spot prime as required in bare patches. Underwater primer makes for a good tie coat. A suitable primer should be in place before antifoul is applied. For Alloy and stern drives 4 coats of light primer before application of Mille Dynamic Antifoul. Always stir all paint before and during use.

 To Calculate your boat’s underwater area….

The following is a simple formula which will enable all boat owners to estimate the approximate surface area to be painted. Measurements are approximate only.

Bottom LWL (length of water line) * (Beam +Draught)

Spars length * mean circumferance

Decks LOA (length overall) * beam *0.75, less area of cockpit etc.

Topsides LOA (length over all) + Beam * 2 * average freeboard (distance between waterline and deck level).
