Cloth Removal
Often called headliner or hull liner or less affectionately "monkey fur." What I'm referring to is the carpet attached to the cabin sides and roof. When we removed ours, due to mold. We grabbed loose ends and pulled it out. We made no attempt to salvage it. The adhesive holding it was incredibly strong. I was left with a mess of adhesive blotches with impregnated fibers. No solvent I was willing to use did a very good job on it. I resorted to scraping and sanding with all sorts of devices. In the end, I used a lighter to singe/burn off the fiber remnants, then sanded with adhesive backed paper attached to a disk in a drill (like 40 or 60 grit). After many hours, I was left with a semi-rough but clean surface and I avoided sanding or gouging through the hull. I painted over it with 2 coats of oil based Kilz white with mold inhibitor. My thought was that if I didn't like the look (too crude), I would proceed to install a new liner or concoct some sort of wood trim to give a finished look. Fortunately, it passed the Admiral's inspection and we proceeded to launch. You can find my story in last June or July's archives. The boat is an H23. I reposted this part of the saga as there have been several related questions recently. It isn't clear to me if your situation is the same as mine was, but I hope this helped. I'll be the first to admit that my method or result would not appeal to everyone, but it does give you the flexibility to simply recarpet when you get the old stuff out and the adhesive knocked down, which is the biggest part of the job. You will definitely become intimate with the construction details of your boat

I just did this...
I just did this... I'm just finishing this project on our boat. Ours is a '79 Hunter 27 and had the original hull liner which was very ugly, moldy and stuck up the whole boat. I found that cleaning does nothing for the mold the resides behind the liner. This project can be messy but is well worth the effort. I short, I removed the old hull liner fabric in the v-berth, after berth and in the salon. Some of the foam backing came with it and some stayed glued to the hull. I scraped off the remaining pieces of foam, used an orbital sander to get the remaining stuff off as well as the glue. Be careful when sanding and scraping as you don't want to hit raw fiberglass. The brown stuff you encounter is epoxy, not glue. Leave the thick brown stuff there and just sand enough to get the foam chunks off. With an orbital sander and 120 grit it won't take much pressure just some attention to detail. To judge if you've gotten the foam off, lightly wipe your hand over the surface after sanding. If you feel and area that's like velvet or is soft, sand a bit more there. I would not try in any way to burn this off, especially with a lighter, since remnants of glue/foam or the epoxy could be flammable or toxic when melted. After sanding, I used TSP to clean the surface (which I highly recommend) then gave it two quick coats of white mold inhibiting paint. I then put up fairly inexpensive berber carpet from Home Depot using tile/carpet adhesive - only enough to get the carpet to stay put but not so much that I can't remove it fairly easily. I did think about using large pieces of industrial velcro in strategic places but opted for the smaller amounts of glue. I like the carpet as it adds a sound barrier against outside noise, relieves echo and adds warmth. Our '79 boat looks fantastic and smells like a new home! The removal process was messy and the most timing consuming part but everything after that was incredibly easy. There is no doubt that this was worth the trouble. The before and after are like night and day. Knowing what I know now, I'd do it all over again in a heartbeat. I can give you more details if you like, including what I learned to be other good methods as I went along. I agree that you do get to know some of the unseen places of your boat. Not bad to get the additional information as you work. Happy sailing!
