Quick question for you wood guys...
Have an overhang (joists and rafters cantilever over the "garage proper" to form a covered patio-type barbequing area by the garage... just removed the buffalo board "ceiling" the original owner put up with 3/8" fir plywood (and installed some extra light fixtures) joists are on 24" centres and the plywood has already swollen and bowed (up between each joist)... it's pretty moist out there tonight, the wood is only primed (and probably still wet from that) with Behr exterior latex primer, and secured with 1 1/4" flooring screws...
Any idea how to fix this/prevent it from happening? Once it dries out and I get a topcoat on it, will that probably help?
