Paint stripper first (just do a search on marine bottom paint

It will soften the gelcoat along with the old paint. Use only strippers specified for use on fiberglass! This is a very dirty, nasty job. If you are able to afford it, it is really worth paying someone else to do this particular job. Most professionals use a heavy scraper if the paint is really hard and brittle. It's a tiring job, but can be quicker than applying softener, as the paint flakes away in large chunks. |

Depending of the thickness of the bottom paint, marine chemical remover is
popular. It costs about $100.00 per gallon and depending on the size of the boat; you will require several gallon to do the job. Marine remover is more expensive. Regular chemical remover is much stronger, cheaper and if left too long will soften the gel coat. You may want to experiment with it, Wal-mart have the best price for regular non-marine paint remover. Sanding (dry and wet) and scraping are used less and less. If you have a skirt around your boat, you will require a breathing and vacuum systems. I like the pneumatic double action orbital sander with 30 – 50 grit open coat sand paper to start. As for scraping, I use a carbide blade. Steel scrapers are good as long as you maintain a sharp hedge. As I get closer to the gel coat, I use 100-120 grit open coat sand paper.

recall Tom talking about is a piece of paper about 3" x 5" properly printed by a bank with about $2,500 written on it:) As most of you know, I'm a real do-it-yourselfer but some things just aren't worth it. -- Roger Long "Thomas Wentworth" wrote in message news:7tcWf.1303$ZJ.181@trndny04...

You may think I was trying to be a smart ass instead of helpful but,
trust me, whatever other method you used doing it yourself, you would quickly conclude that I was being immensely helpful. This might be more helpful. It the stuff isn't flaking off, just slap another coat on and figure it out next year. Think of it as ballast. Smaller boats have gone around the world with sheets of copper tacked over the bottom with felt underneath. I little extra hull thickness isn't going to hurt anything for cruising and nobody's going to see it. If it is flaking off, just knock of the loose stuff with a scraper and have at it with the paint rollers. -- Roger Long "Thomas Wentworth" wrote in message news:fsfWf.1925$Q9.861@trndny07...

I still think sodablasting is going to be a better way to do it. The problem with just scraping the loose stuff and then painting over it all, is that eventually, the stuff underneath lets go... and if it does so in a large enough chunk, you'll end up with a big section of unpainted bottom...and that may be asking for trouble. |

Roger's right. I didn't have $2,500, so I went part way with my 26
footer. I paid to have the old paint soda blasted off for about $25/Ft. It removed the old ablative and the barrier coats, and exposed all the blisters that had been hidden. I then spent 50 hours digging out and filling blisters, finish sanding the entire hull, applying 3 barrier coats and 3 ablatives. It was very rewarding but I'll never to it again. Next time I'll have it blasted and inspect it thoroughly after blasting, blister repair, barrier and ablative coats and pay for all that. Good luck!

I don' know where you are, but in the upper Chesapeake I hired a
fellow who had a scraping tool he developed. Took 20 yrs of bottom paint off a 33 ft sailboat I bought for a cost of several hundred dollars. Took him about 6 hours to do it. I had tried the gel peel approach and found it a real mess and not very effective. This approach was a bargain and no where near as abrasive as blasting. |

Bottom Paint ,,, 20 layers of Bottom Paint ,,, how to remove it.
Many years ago, we hired a yard to sandblast about 15 years of bottom paint.
The resultant texture was a fine-grained sandstone. The first coat of paint filled it. Thereafter, we sanded clean each year and ultimately switched to ablative paint. I'd suppose that there are less hostile blasting methods (walnut hulls, soda?) and that a LOT depends on the care of the operator. Were I to do it again, i'd instruct the operator to try for a 90% complete job and i'd sand the rest. \ "Ryk" wrote in message ...

I saw a 41' Island Trader that had the bottom blasted and the gelcoat was
pretty much destroyed, cracked and chunks missing. Hadn't seen that before or since. Think it might have been the quality of the gelcoat? MMC "Jim Conlin" wrote in message ...

BAKING SODA Blasting is the latest thing.... $50/ft on average and your
bottom will look like new. I did sand blasting on my boat a few years ago and 5 years later it needed a complete PEAL.... After removing all the bottom paint, start with 4 coats of 2000 and then a coat or 2 of bottom paint.

This might be more helpful. It the stuff isn't flaking off, just slap another coat on and figure it out next year. Think of it as ballast. Smaller boats have gone around the world with sheets of copper tacked over the bottom with felt underneath. I little extra hull thickness isn't going to hurt anything for cruising and nobody's going to see it. If it is flaking off, just knock of the loose stuff with a scraper and have at it with the paint rollers. -- Roger Long I'm in full agreement with Roger. At most, I might sand the rougher spots smoother. It's been there for a while, and probably has some protective properties left. (Despite the manufacturer's instructions, I got 3 years out of hard bottom paint that was dry 4-6 months a year.) That said, when we got Xan a decade ago, we got into a deal with a sandblasting guy who was going to be in the yard anyway. Any time that winter/spring, didn't have to be perfect. Time and materials cost was about $500. Gel got a little pocked, but nothing to worry about. If I had to do it myself, friends swear by the carbide scraper. -- Jere Lull Xan-a-Deux ('73 Tanzer 28 #4 out of Tolchester, MD) Xan's Pages: http://members.dca.net/jerelull/X-Main.html Our BVI FAQs (290+ pics) http://homepage.mac.com/jerelull/BVI/ |
