flooring
 

I am about to lay a t@g solid 5 inch oak 5 floor on top of a 6 inch
red deal t@g floor (in the same direction).
I have successfully completed a similar project in a small area 10*10
ft several years ago.After a few years I got a small amount of
creaking on this floor its not a major problem. I put the oak directly
on top of the red deal secret nailing into the joists with no
plywood. The question I wish to ask is what is the recommended way of
completing this job?.
