Three removal methods dominate the bottom paint scene these days: soda blasting, chemical stripping, and mechanical sanding. Wooden- boat owners have the added option of using heat to remove old bottom paint, while aluminum or steel hulls can stand up to sandblasting.
Acetone will dissolve most other polymer finishes including enamel paint and fiberglass resin, so it’s not the best choice for cleaning painted or fiberglass surfaces unless you plan on refinishing.
That means it can kill or injure them in the wider environment too. Most bottom paints contain copper and all of it eventually leaches into the water. This happens at an estimated rate of two pounds of copper per year per 30-foot boat.
Painting Over Existing Paint If the existing bottom paint is in good condition, you may want to just recoat the bottom with a maintenance coat. Prep the hull by pressure washing the bottom. Do this or have it done, when the boat is first pulled out and any bottom slime is still soft.
How do you remove Antifoul from gelcoat?
Wet abrasive blasting is the fastest, most efficient, and most economical way to remove antifouling paint. Using chemical stripping, the removal of antifouling from an average boat takes up to six days. With vapour abrasive blasting, the job is done in less than a day.
Bottom paint (aka antifouling paint ) is a paint or coating designed to discourage weeds, barnacles, and other aquatic organisms from attaching themselves to (and in the case of wooden boats, eating) the underwater portion of your boat’s hull.
How do you remove Antifoul from Aluminium?
Antifouling paint will come off very easily from aluminum mechanically, grinder with a wire wheel or an electric sander.
Copolymer paints with anti-slime additives are best for heavy fouling areas. Environmentally preferable Ultima ECO and Pacifica Plus are ECONEA-based copolymer ablatives. Ablative paints (of the non-copolymer type) work in a similar way and minimize the annual ritual of sanding when applying a fresh coat.
Ablative paints are typically reapplied every 1–3 years.
Don’t scrub ablative paint underwater. Usually a fast run or a light sweep with a hand or soft sponge will help the paint shed any surface coating — but don’t wait too long between cleaning runs (see point No. 2). Ablative paints should not be abraded or scrubbed underwater, period.
Can I use acetone on a boat?
Yes, you can use acetone to clean the gelcoat prior to application of VS721, however there are numerous reasons to use Boat Scrub instead. Acetone is intended for use during repair or construction of the fiberglass, not for general maintenance. Regular use can also be damaging to the gelcoat.
