Author Topic:   Anti-fouling paint removal

Just bought a 15 sport. Florida boat: has blue anti-fouling paint on botton. Since I use it in fresh water only, I want to remove this stuff without hurting the gel (which is perfect). What can I use?

While there are several ways to remove bottom paint, I have found the best by far is Peel Away, available at any marine discount center. The stuff has the consistency of mayonaise. You trowel it on heavy and cover it with paper that is supplied with the Peel Away. Wait several hours. Again, WAIT several hours and then take a wide-blade putty knife, pierce the paper and check to see if the paint is ready to come off. When applied properly, the paint will peel away like sliding a knife through butter. If the paint does not come off, let it work longer. But the key is to lather it on thick. Remaining residue can be removed with water and a Scotch Nylon scrubbing pad.
I have used this stuff on my 36-foot Delta (eight years worth of Fiberglass Bottomcote) and my 17 Whaler. The bottom will come out brand spanking new. You can even tell if the bottom was properly prepped (sanded) when new.
Place plastic or other type of ground cover under the boat so the paint droppings collect and are easy to dispose.
Peel Away is water based, which makes it especially user friendly for weekend warriors. It is messy, but the chemicals are fairly safe and it is one of the few products I recommend.

okay what do you about the areas of the hull that are on the bunks? How do you get at them inorder to remove the paint?
Curious 'cause I'm planning to remove my paint also.

I also have a Sport15 that has blue anti-fouling paint. I trailer the boat so I thought it would look better with the paint removed. The bottom paint "remover" should be relabled and sold as paint "Restorer" because after many coats and much scraping, the blue color was much more vivid. I finally gave up and repainted the bottom black. It looks 100% better.

Sea Hag: You have to move the boat off the bunks to get at those spots. When I did the 36-ft Delta, it took two of us two hours to spread the Peel Away and three hours the next day working like dogs to remove the paint.
This was an inboard boat with prop shafts, struts, etc. We spent several more hours cleaning off those tight areas.
There's no free lunch when it comes to bottom paint removal. But I guarantee you that after you do it, you will never paint on bottom paint as thickly as you use to!
I use ablative paint on my Montauk and a few times during the summer, take the boat to the island, and scrub the bottom with a stiff brush. I get the same RPM at the end of the summer as I do in the spring.
It's all about maintenance.
