SURFACE PREPARATION AND APPLICATION PROCEDURE METAL (BOAT PROPELLERS)

Degrease the surface with a suitable solvent (nitro, epoxy or polyurethane based. Sandblast if possible or in alternative sand with  coarse grain sandpaper (80-100 grit). The substrate should have a suitable anchor pattern. Do not use old sandpaper or wire brush as they may  cause a polished  substrate and reduce the anchor properties for the primer application. Remove dust  with a dry vacuum cleaner. Avoid touching the surface with hands in order not   to leave traces of grease or dirt which could impair the application. Apply a first  coat of ELIPRIMER 1C allowing the recommended waiting time between coats. Wait from a minimum of 4 hours to a maximum of 12 hours (20°C) and overcoat  with a first coat of CONTENDER ELICHE antifouling. Apply a second coat of CONTENDER ELICHE antifouling   within 4 hours     from the application of the previous coat. Launch  into water after a minimum of 24 hours.
