Can you glue down wood flooring on top of
subfloors?
The answer is yes, only if your subfloor is CDX
plywood or above. Always make sure that your sub-floor is clean and
free of debris. If your sub-floor is uneven you must level it off.
A good way to level off a sub-floor is to always make sure to use a
straight edge and find the low spots. If you have low spots, they
must be filled with float. A high spot can be sanded down of shaved
down to meet industry standards.
