We're looking at putting up a tongue and groove ceiling in our kitchen to match the T&G we just finished in the porch (the kitchen opens into the porch) and we had a quick question. When we put the T&G up should we put it directly against the joists, should be use something like tar roofing paper first to seal the ceiling, or should we put it over sheetrock?
There is currently a dropped ceiling we are removing so if it's best to put it over sheetrock then we'd have to patch the ceiling where the drop is first. Just didn't know if there was something we should put up first before the T&G to be sure it's all sealed.
When we first did the porch we treated the top of the T&G with Thompson's Water Sealer to be sure that the roof side is protected. Didn't know if that was best to do here or if something else should be attached to the joists first.
Thanks!!!
