Very small ceramic tile project
Actually it's a tiny project compared to everything else I'm doing but still want to do it as correct as possible.
I am creating a 18" x 54" hearth from 3 pieces of tile, and they need to be raised 1/2" above the existing 3/4" plywood subfloor. They will never see foot traffic so I'm not sure if I need backer board or could I just use 1/2" plywood?
How much does mastic raise the tile?
Thanks in advance.

Using thinset rather than mastic, it will raise it nominally 1/8" or so once they are pressed in place. I would use the 1/2" CBU for the additional space rather than plywood. What are you going to do about the edges?

OK, thinset it is.
I didn't see 1/2" CBU at HD, maybe I missed it. Can I use 2 pieces of 1/4"? What if I need to adjust the height just slightly?
As for the edges, the thought is to just leave them exposed since they are finished and will only sit the tile thickness above the adjacent laminate floor trim.

I would use a 1/2" sheet. They are available.........right.......next to the 1/4" You'd have to be the judge on the edge. I just wanted to bring it up.

Was checking the HD website and didn't see 1/2" listed. Searched again and there it was. Under 'Drywall'.
Thanks for the help, sounds straight forward.
