1/4 subfloor over 3/4


I was told to put 1/4 mahogany over my 3/4 subfloor to tile on. Just wondering what to use to fasten the 1/4 ply, nails, screws or staples and how many ( every 6 inches) or more or less. Thanks

You should use 1/2 for ceramic and 1/4" underlayment grade for vinyl(not mahogany or luan, they have voids in the layers which can collapse) . For vinyl the 1/4 inch ply needs to be stapled. Screws wil cause it to pucker, nails will leave dents. It should be stapled every 4" in the field and every 2" along the seams.


Guess we were posting at the same time.

Do NOT pay attention to that person.

AH.....not sure what you mean, but probably not.


You do not need any more plywood for ceramic/porcelain tiles if the 3/4" subfloor is plywood as apposed to planks. Do NOT tile directly over the second sheet of plywood in your subfloor system. (if you have 2 layers). You need either a tile backer board or a membrane such as Ditra to tile on to.

So, for ceramic/porcelain a 3/4" plywood or OSB subfloor is adequate if in good shape. Then install the backer or membrane and then the tiles.

To make sure your framing meets specs, let us know the type and size of the joists. Their species and grade if at all possible. The spacing of the joists. And the unsupported span of the joists. Also confirm the type and number of layers of the subfloor sheets.
