The kind folks at Woodmanor.net usually leave the inside of their clubhouses the bare plywood. They have seen people put down outdoor carpet, linoleum, and wood flooring. I am inclined to think of the plywood as a subfloor and to install some kind of flooring. If the fllooring ever became damaged, I could easily pull it out and replace it. If the plywood ever became damaged, repair or replacement would be difficult. The people at lumberliquidators.com said their flooring is not rated for outdoor use and did not recommend it for the clubhouse.
What kind of flooring should I use inside the clubhouse? What about on the porch?
