Craters and Fish Eyes

Small, crater­like openings in the finish caused by contamination on the surface being painted.

Causes:

  • Improper surface cleaning

  • Effects of previous repair

  • Contaminated equipment

  • Wrong reducer

  • Wax on the surface

  • Water or oil in the air lines

  • Workers using a silicone containing hand lotion or cream

  • Old finish containing excessive fish eye preventer

  • Wrong spray technique/improper dry times


Solutions:

  • If the coating is still wet, wash off with the recommended reducer, and properly clean and prepare the surface before proceeding with any further painting

  • If the coating has cured, wipe down with Awlgrip Wipe­-Down Solvent (NA/AP: Awlprep Plus T0115; EU: Surface Cleaner T0340) using the Two Cloth Method


  • Awlgrip Wipe-­Down Solvent (NA/AP: Awlprep Plus T0115; EU: Surface Cleaner T0340) will clean most surfaces thoroughly. In some cases, especially on fiberglass, extreme surface contamination such as mold release wax, silicone polish wax, diesel fuel or oil is present. In these situations, you must scrub the surface with a powdered household cleanser and a Scotch­-Brite® pad until rinse water applied to the surface “sheets out” over the entire area with no breaks or holes in the water film.

    Blow dry the surface and thoroughly wipe the surface to remove any cleanser residue and help remove moisture on the gelcoat.

  • Smooth sand, then re­-clean with Awlgrip Wipe­-Down Solvent (NA/AP: Awlprep Plus T0115; EU: Surface Cleaner T0340)

  • Tack off surface and re-­coat


Prevention:

  • Clean surface thoroughly with Awlgrip Wipe­-Down Solvent (NA/AP: Awlprep Plus T0115; EU: Surface Cleaner T0340) or Awlgrip Wipe-­Down Solvent (NA/AP: Awlprep T0008 or Awlprep 400 T0170; EU: Surface Cleaner T0340) before and after sanding.


Only use Awlgrip Wipe-­Down Solvent (NA/AP: Awlprep Plus T0115; EU: Surface Cleaner T0340) to remove wax. Other de-­waxer solvents will melt wax into the pores of the gelcoat substrate.

  • Solvent wipe the entire surface with Awlgrip Wipe­-Down Solvent (NA/AP: Awlprep Plus T0115; EU: Surface Cleaner T0340) or Awlgrip Wipe-­Down Solvent (NA/AP: Awlprep T0008 or Awlprep 400 T0170; EU: Surface Cleaner T0340) using the Two Cloth Method.

  • Drain and clean equipment

  • Use proper spray technique, select proper reducer

  • Allow sufficient dry time between coats
