Barrier Coats and Antifouling Bottom Paint

Why are Barrier Coats and Bottom Paint necessary?

Gelcoat is a porous material and will absorb moisture when your boat is left in the water for an extended period of time. The water entering the hull chemically reacts with the glass fibers and uncured resins. This reaction produces pressure which causes blistering and cracking in the surface. Once blisters and cracks start, the boat’s laminate will absorb water like a sponge. Antifouling paint alone will not prevent this from occurring; an epoxy barrier coat must be applied to seal the hull prior to bottom paint. The barrier coat will protect and seal the hull. The antifouling paint provides protection against barnacles, mussels, weeds and slime. Protection is always better than the cure.

Bottom Paints do not have to be ugly

Our most popular bottom paint is Vivid antifouling paint by Pettit. It is a hybrid high-performance, multi-seasonal, dual-biocide antifouling paint. It is available in a bright white finish which is our most popular color choice. Other colors can be custom mixed from the six base colors to match or compliment your boat color.

Our process to a high quality professional job

Preparation, high-quality products and proper application are key to having a long-lasting paint job.

  • All boats are lifted off trailers and safely supported on stands in our climate-controlled paint room.
  • Moisture levels of the hull are determined; if levels are too high, they are corrected before proceeding. This is the most critical step in the process.
  • Entire boat, excluding bottom, is covered and masked off including around drive.
  • Surface is washed and de-waxed to ensure all contaminates are removed from hull.
  • Entire bottom is sanded with 80 grit paper to achieve a uniform dull, frosty finish. Inadequate surface preparation will result in failure of paint adhesion.
  • Bottom is then cleaned again.
  • The hull can now be inspected for deep scratches, cracks, chips, or blistering of the gelcoat. At this point, any required repairs will be made.
  • Barrier coat (four coats of epoxy barrier coat primer) is then applied (total dry thickness 12 mills).
  • Three medium coats of antifouling paint are applied which offers multi-season protection and optimal performance.

All of our coatings are sprayed (not rolled) in a heated paint booth which ensures even application of the product, smoother finish, complete consistent cure and creates less drag on your boat.

Bottom Paint recoats available

  • All boats are lifted off trailers and safely supported on stands in our climate-controlled paint room.
  • Entire boat, excluding bottom, is covered and masked off including around drive.
  • Entire surface is sanded with 80 grit sand paper to ensure removal of all contaminates and ensure maximum adhesion.
  • Two coats applied by spraying.

Different types of antifouling paint are available for types of environment and uses.

How long before recoat is needed?

  • Recoats are needed because antifouling paints, depending on the type, can release all their biocides or slowly wear away like a bar of soap.
  • Intervals between recoats can vary depending upon product used, type of water conditions, and usage.
  • Man-made pollution and natural occurrences can affect antifouling paint performance—water temperatures, silt dirt, pollution and water flow.
