Carpet
I think that I would leave the old contact cement on if I was going to cover it with carpet. It will make a better surface for the carpet to adhere to. It will save you a lot of work too. I don't know too much about the mildew fighting properties of this carpet, but it's safe to say that most synthetics will prevent mildew more than cotton. Indoor/outdoor carpet would have to be really wet in order to get serious mildew, and I don't see that happening in your cabin. It could happen in the bilge, but not on the cabin wall above the water line of the boat. I remember talking to Rudy years ago about what kind of paint that they used in the bilge and I'm pretty sure that he said something about a rubber based type paint. It probably has a lot of the insulating qualities that prevent condensation. Before you make your choice of what to put on the walls, why don't you give Rudy a call and ask him? I'm sure that he could answer any questions that you may have. Tell him that you talked to me. I like the fabric in my cabin, but I don't particularly like it near my galley area. It has a tendency to get dirty from the stove. Also, there's always a chance that it could catch on fire. I use a stove-top oven quite a bit and this thing can generate a lot of heat. All it takes is the wind blowing a loose flammable item in the cabin on or near the stove or oven when it's going and I'd have a fire. I've raised my stove about 6" when I re-worked my galley cabinet and installed my new stainless steel sink. So things are a little closer than they were before. I'm planning on doing something to the fabric over the stove but I haven't decided what to do yet. That will be another project this fall. Right now, I want to be out on my boat trolling for Stripers.Joe
