Touching Up Bottom Paint - Questions

[obsessive]

My 99' 240DA had a new coat of bottom paint put on it last spring. Well, after pulling her out at the end of the season, I noticed that a few areas were flaking off (not big areas), and that they need to be touched up.

Whats the best process for this. All the other areas on the hull look great, only these 4 spots need touch-up (fist sized).

I was thinking agout sanding with a foam 80 or 100 grit sanding block around and over the areas in question, wiping them clean with a damp cloth (to get rid of the dust, etc.), letting them fully dry, and then overpainting with Interlux.

Is this a good approach?

80 grit works for me. Scuff up any areas you want to touch up then use the same paint that was used last spring.

Incidently, the reason the paint is flaking off is because the bottom was not properly prepared before painting before.

Thanks!

I figured that they didn't quite prep the areas that are coming off well enough.

I don't know what brand they used when they painted it, as it was done before we purchased it. Will this be an issue?

Although you would prefer this not happen, it’s common.

Needing to touch up a few small areas is very common.

Touch it up as suggested and move on. Its not worth ‘obsessing’ over.

I heard that the Cuprous Oxide agent in marine bottom paint is designed to shed lightly in order to keep algae and slime from sticking to the bottom. It's one of the properties of the paint. All I knew was that I had a 37 footer with a 14 foot beam and at $70 plus a gallon, it was a real bummer.

That's exactly why my screen name is 'Obsessive'. Because I am. Perfectly okay to point it out

if possible, ask the folks who painted it what they used. if they used a water-based paint, you cannot go over it with non-water based. if they used non-water based paint, you can go over it with water-based. that's the only non-compatibility issue i'm aware of. others here may know better.

did the paint flake off to the gelcoat? was the paint that was applied last spring the FIRST coat of paint this boat ever had? if it was the first coat, then it's a prep problem. if not , maybe they used incompatible paints.
