It’s difficult and expensive to remove bottom paint and restore a smooth gelcoat finish. If you find a boat that you otherwise love, but it’s been bottom painted, there’s no law that says you have to remove the bottom paint to keep it in dry storage.
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.
Bottom paint prevents growth of organisms that attach to the hull and can affect a vessels speed, performance, and durability when boat is kept in the water for extended periods of time. After you apply hard bottom paint it is very durable and does not wear off.
There’s some debate about this but the consensus is, yes, bottom paint can slow your boat down. If your hull has a nice slick paint job then you may not notice much effect. You’ll end up with drag and your boat will slow down and use more fuel.
Tape off the paint and blast it, or let a biodegradable chemical stripper do most of the work. If you’re lucky, the boat has been dry-launched for its whole life and the bottom is paintless and perfect. At first glance, bottom stripping looks easy when the paint is so loose that a putty knife can just push it off.
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.
How much does it cost? According to Armstrong, the price varies depending on the length of the vessel. For example, a 30-foot boat might be around $45 per foot, while a 100-foot boat would be around $130 per foot because of the increased beam. “Our average job works out around $35 to $45 per foot,” he says.
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.
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.
Should I Bottom paint my boat?
If you pull your boat out of the water every time you use it, you probably don’t need bottom paint. But if you keep your boat in the water all season, or if you take your boat out of the water periodically, such as on a trailer or lift, then yes, you should apply bottom paint to prevent hull fouling.
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.
Should you Antifoul propellers?
Composite propellers can be directly coated with antifouling. The safest thing to do is to bag his propeller that doesn’t let in the light. Indeed, the animals that colonize our hulls need light to live. But this extreme solution requires you to dive every time you want to use your sailboat.
Can I paint over antifouling paint?
Most modern paints should be compatible with each other. If you’ve taken the existing antifouling back to the yacht’s gel coat or epoxy coating, it’s recommended that you paint the hull with primer to ensure good adhesion.
