Hi there! Newbie here, getting ready for new Marmoleum. The install guy came and took a look at my '55 Kenskill and suggested replacing the deck before he added a 1/4" subfloor. He said I should get marine grade plywood for the deck with a tongue and groove for the join so that the Marmoleum would not crack in the future. The current deck is not rotten, but surely warped a little and he would like to see a more solid join to prevent cracks like the old floor had. This is before I took all the cabinetry out... Couple questions... 1) If I replace the deck with 3/4" plywood and then he adds his 1/4" subfloor, won't that raise up my closets by 1/4" and create problems putting the skin back on? 2) Marine grade plywood is pricey! My lumber guy suggested full-faced plywood and sealing it on all sides with McCloskey varnish of some kind. Anyone try this approach? 3) Tongue and groove is not easy to locate and also expensive. Lumber guy suggested locating seams on the joists and making biscuit joints. Have others tried this? 4) The belly is kind of ragged underneath, but not a nightmare. There are some dark spots. Should I go whole hog and re-do everything and if so what would you replace the belly and insulation with? Thanks so much for any input!! More photos... Save

Wow, this is a hard question to answer. Marmoleum is very sensitive to movement and usually is in 6 foot widths. (that means seams) However, I'm not sure tongue and groove or marine grade are absolutely necessary.
The belly can be coated with a water based Henry dampproofer paint application. I use it on a lot of bellies. It dries to a rubbery black and clean up is easy.
That being said, how fancy are you going? If you want everything picture perfect, then the subfloor is very important with Marmoleum. However, there are some cool vinyls out there that give and take. Certainly will look great in your trailer. (I'm thinking the thicker non-glue flooring but I glue anyway)
If you are not taking the cabinetry out, the subfloor may not matter so much. Meaning, the 6 foot width would not be compromised if not quite level.
I would do a little more research before proceeding. Hope this helps.

Thanks VK!
Yeah, the Marmo seam would run entirely under cabinetry on the driver's side of the trailer. Just visible in a small area near the booth and I hope the pattern hides it somewhat.
Cabinetry is already out. What's there is yucky. I think I need the subfloor. Won't matter with kitchen cabinets but would raise the closet. Plane or sand it down on top later? Is that weird?
Glad you think the belly can stay!

Also, if I patch the Celotex with soundboard, do I seal the seams with the dampproofer or tape or something else? Thanks so much!

Yes, you can make adjustments to the closet, either sanding or careful cutting. Another option would be to install the closet, then install flooring. I don't usually go with Marmo, but think it would be better laid flat with the closet on top...
Celotex holes: Depends on how big they are and how you have to piece it. Sometimes, a person can glue/attach a backer half on the old piece, then insert the patch with glue/attachements. For seams, dampproofer should seal. The trick is to figure out how to make everything secure. Without seeing it in person, not sure what you're up against.
I'm working on a flakey belly at the moment. Coating the underside has helped. I will see if it will hold or need some sort of support the length of the trailer. Sealed Masonite comes to mind, if need be. Maybe put blocking on the frame to keep it in place.
Anybody else have ideas? It's not always possible to replace the complete belly, so what to do?

Thanks VK! That helps a lot. The Celotex hole appears to have been cut out to grant access to plumbing. I think it's going to be fine.
I think it would be better to have closet on top of the new flooring too, and plane it down later. Welting will cover the seam...
