I live in Ontario and would like to know what type of flooring should go over my subfloor.
I have installed Platon dimpled membrane on the concrete floor and am wondering if I need to use the OSB grooved flooring overtop it or can I butt plywood sheets against one another. Do the 4x8 sheets need to be screwed down or not. The Platon is screwed down.
I plan on installing carpet on top of the flooring.
I suspect OSB is the right choice but I do have several sheets of 3/4 inch plywood which would do part of the job. If OSB what size would be best?
