Surface Preparation
- GRP — Ensure surface is dry and free from traces of wax, lubricants and other contaminants. Treat if required with Navimare Gelclean and wash with fresh water.
- Wood — Ensure surface is dry. Sand and remove the remaining dust with dry rags or rags slightly dampened with water (not solvent).

- Coated substrates — Existing systems should be dry and free from loose paint, salt, grease and other contaminants. High pressure wash with fresh water and allow thorough drying.
Usage Instructions
Substrate should be dry and free from contaminations. Relative humidity should be less than 90% RH. Mix pack A and pack B well, preferably by means of a mechanical stirrer. Do not mix more paint than can be used in 1 hour. Thin if necessary with the specified thinner. Apply crosswise to ensure even distribution. Avoid excessive application. Apply 2 coats for underwater areas and one coat for above waterline areas. Wear protective clothing, goggles and gloves. Refrain from smoking at all times.

(1) The surface should be dry and free from salts and other contaminants prior to overcoating. The best intercoat adhesion is achieved when the subsequent coat is applied before the preceding coat is fully cured. After prolonged exposure times it may be necessary to roughen the surface in order to ensure intercoat adhesion. When in doubt, consult your nearest Navimare office.
