Re: Getting rid of house paint on a hull

I suspect that a heat gun and scraping will take off most house paints without damaging whatever gelcoat or raw frp is underneath. Or using one of the weaker chemical strippers which is known to not harm gel coat when removed "soon". Some of these come with a cover material, so you slap it on, cover it, then peel the mess off (including the old paint) and throw it away.

I'd try out the choice on the transom first, because that usually is the smallest area that you can isolate and if necessary refinish without getting into a whole side of the hull.

House paint says the PO may have been a butcher, there may be land mines in the boat, so mistrust everything until proven otherwise.

As to repainting...there are plenty of videos and threads online about that. You pick a price point that you can live with, and that's the end of it. If you want a real "yacht" with a mirror finish? You job it out to a paint shop, because you'll need some skill, and the expensive toxic two-part coating, AND a dust-free bug-free closed environment to get that. If you've got patience, skills, and really great weather, you can come close on a DIY, but that "paint" is expensive.

Re: Getting rid of house paint on a hull

Try an electric heat gun first, see if you can get the paint to bubble then strip with razor. If not, next step is Red Devil paint remover. If that doesnt work, then go to soda blast. Be prepared to repaint with two-part epoxy (best) or single part epoxy

Or industrial urethane or enamel.
Don't want to overcapitalise by paying more for the paint job than the boat is worth.

Re: Getting rid of house paint on a hull

I had not thought of trying a heat gun. Worth a try but be careful as you can burn gelcoat and it will soften and be easy to gouge when it gets hot. If you do try it, I suggest you make your own scrapers out of some discarded acrylic sheet. Here's an example:



The benefit is that these are tougher than the junky plastic spackling knives but won't gouge the gelcoat like a mistake with a metal one will. You can get very aggressive and move fast without worrying about damaging gelcoat.

I cut mine out of a discarded sheet from a lobster tank with a band saw. I have about 10 of them shaped and sharpened with a belt sander. They will dull fairly quickly so for a bigger job I cycle through them and batch sharpen then when needed. These are also awesome for getting old caulk off gelcoat.

Re: Getting rid of house paint on a hull

when we had to remove an unwanted name on an old boat, the painter putting on the new used EZoff spray on oven cleaner. Bubbled up the old paint relative quickly, which then scrapped right off and cleaned up with a wipe of thinner. No damage to the gelcoat and the mess was controllable. Just do a couple square feet at a time. Of course do a small test patch first.

Re: Getting rid of house paint on a hull

Ted-
EZ Off is basically lye. A very old fashioned and effective caustic alkali stripper used in many of the "purple" home cleaners. And as a friend of mine found out the hard way, it will take the finish off wood cabinets very quickly along with the dirt.
Using EZ-Off for an entire hull would be very expensive. And lye does attack hulls, Unless it is promptly removed, flushed with water, and neutralized with a mild acid (like vinegar) the hull may be burned to a yellowish color or actually damaged by it.
In a small area with prompt attention? Yes. But for an entire hull? A big risk to the hull, a big risk to the skin and lungs and eyes of the folks applying it. Not something you'd really want to do, if you had any alternatives.

Re: Getting rid of house paint on a hull

You can also use the same products they use to remove graffiti: http://www.graffitiremovalinc.com/products
Some products are designed to be use on Fiberglas with and a pressure washer.
