Removing Foam Backing
I'm in the process of removing the carpeting inside the cabin of my
sailboat. The manufacturer used carpeting with a foam backing to line the inside hull as sound and thermal insulation. The problem I found was that the carpeting pulled out easily but left the foam attached to the old adhesive on the inside of the hull. I started scraping the foam off but soon discovered how difficult this is, scraping off the foam inch by inch. I was wondering if anyone has run into this problem before and found a better solution than using a hand scraper. I thought heat gun but wondered whether I'd poison myself. As a follow up question, I'm replacing the old carpeting with Seaquest vinyl fabric. Anyone have any suggestions for the best adhesive to use. The West Marine catalog lists an adhesive they sell, but states it's for carpeting. Was wondering if I could use carpet adhesive or if there's something better. BTW, the old foam is moldy, it has to come out. I can't just put the new vinyl over it. |

Removing Foam Backing
My last boat had a foam backed vinyl on the interior. The foam dried up and
fell apart, resulting in the vinyl falling off, but leaving a coating of glue and the remnants of the foam on the fiberglass surface. I removed this residue with a variety of methods. A heat gun worked, as did a thick paint remover (making sure to scrape off and wash from the fiberglass as quickly as possible). I replaced the old with a closed cell foam material. First used solvent based liquid contact cement, but I think you will find as I did that this can slightly dissolve vinyl material. I then discovered a water based contact cement from 3M. IIRC, it was about 3 times as expensive, but was so much thinner that it had maybe twice the coverage. Fumes were so innocuous...almost could say it smelled good. I ordered this product from a NAPA store. Gallons only. Get several cheap brushes as they get gummed up. wrote in message ...

You mention that if used paint remover should be washed off quickly. Not to argue but I believe that you should emphasis that most common paint removers will destroy fiberglass and should be used very, very carefully. Cheers, Bruce (bruceinbangkokatgmaildotcom) |

Removing Foam Backing
You are correct.
But I expect there is a major time gap between when the paint rmover will loosen the old glue and when it will attack the polyester. It certainly didn't have time to attack the surface I was working on. And was washed off with water after scraping. It's been a dozenyears, so I'm a little fuzzy, but I think i may have removed as much as I could with a heat gun (got to be careful with that as well), and then cleaned up the remainder with the paint remover.

I guess that the reason I am rather gun shy about paint remover is my initial experience with fiberglass. Bought a elderly fiberglass sloop and, as I would with a wooden boat, proceeded to remove the paint using paint remover. The first part, a hatch cover, had been soaking only a short when I "tried it" with a paint scraper and scrapped off the paint, gel coat, n' everything. Frantic water blasting with the hose saved the cover but I did need to use a lot of high build primer before I painted it. As general information, that you may already know, they now make some sort of "paint remover" that is safe to use with GRP. You slosh it on and then cover it with old newspapers. After a while you peel off the newspapers and the old paint comes with it. Environmentally friendly, I guess.

Removing Foam Backing
That's certainly a reason to be cautious. Perhaps the difference is that the old glue is softened so much quicker by the paint remover than paint would be, that it can be scraped and washed long before the polyester resin would be affected. I wasn't aware of the other paint remover you describe. I'll try to remember to look for it if I'm ever faced with the need.
