Bottom paint removal problem
toggle quoted messageShow quoted text
Sorry I could not find the paint stripper I used.
West marine has some products but they seem expensive. You might need 10 gallons.
My local paint supply says there a number of products that will work . However, when you get close to the
gel coat you should not let it sit on the hull too long.

I do not remember the name. I will try to get the name for you tomorrow.
It took 2 yard workers 4 days to strip and sand.
It is best applied in a warm environment as it is a chemical reaction.
I did mine in July. They used cheap brushes and scrapers for the majority of the work and then putty knives when they got close to the gel coat. It takes multiple applications and waiting time for this stripper to work.
They then used a sander to complete the job. It wasn’t difficult just time consuming.

Eric, I need to remove 20 some years of paint. Do you remember the name of the product you bought from Home Depot ? Was it meant to be used on fiberglass? Have any idea as to the man hours to strip your boat. Thinking I may hire a helper or two and tackle it myself.

I have owned my Super Maramu since she was launched in 2003. Amel applied a hard bottom paint before launch in 2003 but since then I have only used ablative paint. The layer is now thick and a bit uneven. Having carefully examined the words of caution on the Amel owners group, particularly those of Joel Potter, I have looked in vain for a soda blaster to remove all the old bottom paint. I just cannot find one in Rhode Island. The contractor recommended by my Rhode Island marina uses glass and is apparently very experienced with blasting boat bottoms.
Last week I contacted the large Hinckley repair yard in Portsmouth, RI and it turns out that they do not have access to soda blasting either and use the same glass blasting contractor used by the full service marina where Sabbatical III is stored. Hinckley recommends the glass blasting followed by 5 coats of epoxy (the 5 coats is their rule for European boats). My yard has suggested 3 coats of epoxy as a water barrier.
I had been hoping for soda blasting plus a single coat of epoxy as a primer, on the assumption that the barrier coat under the gel coat would remain intact. I did not expect that it would not be possible to find a soda blasting contractor in Rhode Island (or nearby Massachusetts) who works on boat hulls.
Any suggestions for me? I feel stuck and am inclined to use glass blasting following by 3 or more coats of epoxy as a barrier coat.
