    I'd be curious to hear from anyone who has glued new luan panels.

    I thought that it was just the vinyl that was unglued but when I started tearing that down, about 2/3 of the luan also came down with it! I've since repaired the Filon roof leaks (Dicor lap sealant and Dicor Fiberglass RV Roof coating) and am getting ready to tackle the ceiling.

    I've got all the foam exposed sanded and prepped. It was suggested to me to use PL Premium but being a polyurethane, it may not provide good adhesion to the foam ceiling. I'm now considering the Green contact cement or Liquid Nails LN-903.

    The press-tite green contact cement is water based and compatible with foam. It's easily spreadable. The LN-903 is very weather, humidity and temperature stable, but comes in a tube and will be much more difficult to spread evenly.

    Any other ideas?

    Sounds like you know what you're doing and have done your research on adhesives and foam. I've never used press-tite contact cement, so I have no opinion there. Except to say that as you probably know, with contact cement you get only one shot at applying the luan in the right position.

    I think I'd be more inclined to use the LN-903 for just that reason. I don't know what the working time (or set-up time) is on LN-903, but I know that you'd be able to adjust the panels here and there if you didn't get them spot on on the first attempt at applying them. As far as spreading it evenly is concerned, you can get a cheap notched trowel (the type used for applying adhesive when installing sheet vinyl flooring) at a home center and use that to spread the adhesive. They really work a treat! Go for the metal variety of trowel - the plastic variety are kind of flimsy when working with a thick adhesive.

    Good luck, and please let us know how you made out. Oh - and we love pictures! [:D]

    I'm getting ready to replace my ceiling, have torn everything wet out and am replacing the styrofoam. I'm not sure what to use for the ceiling. Would love to see how your's turned out.

    Please share... :)
