BOTTOM PAINTING BARE FIBERGLASS
1. Scrub the surface thoroughly with soap and water using a stiff brush. Flush with fresh
water to remove soap residue.
2. Wipe surface thoroughly with a rag that has been dampened with Interlux Fiberglass
Solvent Wash 202 or an equivalent de-­‐waxing agent to remove mold release agents, wax
and other contamination. Wipe off with a clean dry rag before liquid dries. Wipe only a few
square feet at a time and change rags frequently.
3. Lightly spray the surface with water to insure all contamination has been removed. If
water beads up or separates repeat Step 2.
4. Lightly sand all gelcoated areas with a 3M Medium Scotch-­‐Brite Hand Pad or 320 grit
sandpaper. Lightly sand gray Interprotected areas with a 320 grit sandpaper until blended
into surrounding areas to achieve a smooth finish if desired. Be careful not to sand into the
gelcoat. Sand the keel and rudder with a 220 grit sandpaper to achieve a smooth finish if
desired.
AFTER THE SURFACE HAS BEEN PROPERLY PREPARED
1. Remove the sanding residue by wiping with Fiberglass Solvent Wash 202.
2. Apply antifouling paint following manufacturers recommended application
procedures. A sandless primer such a Pettit 6999 may be recommended for certain
bottom paints.
