Is 3/4 plywood OK for 3/4 tongue and groove?
Q: I am planning to install 3/4 tongue and groove flooring over 2×6 floor joists on 15 inch centers. The room is 14 x 10 and I plan to use screws to hold the plywood down. This room is a small bedroom, should I use 1 1/8 instead or is 3/4 good enough? I plan to go over the plywood with carpet.
A: 3/4 plywood over the joists with 3/4 flooring installed on top is fine. The hardwood should run across the joists. I’m not sure how the carpet enters into this equation.
