Can you remove antifouling paint?
If your existing antifouling is in poor condition, we strongly recommend removing it completely before repainting. There are two methods outlined below, but you could also consider employing a professional antifouling paint remover who will use equipment that’s not suitable for a DIY boater.
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.
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.
How long does Antifoul last?
In the Caribbean, 8 to 10 years would be more normal. Many of the first boats treated in 1991 are still performing well after more than 20 years! Coppercoat Commercial offers our commercial customers up to 30 years of protection. In each treatment applied there is an average thickness of 250 microns of Coppercoat.
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.
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.
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.
Ablative paints are typically reapplied every 1–3 years.
How do you sand paint off aluminum?
You can either use a paint stripper as suggested above or start with rough sandpaper, then finish the part off with a finer sandpaper. It’s what we do and works fine. I would go against using a wire wheel in a drill… Personally, I do not see the up side in painting aluminium structure.
What is the best way to remove old paint from aluminum boat?
Chemical strippers [ best option] – Chemical strippers are known to offer the best results when removing paint from the aluminum boat. After applying the chemical stripper on the surface of the paint, the chemical stripper reacts with the paint and makes the paint removal much easier.
