View Full Version : Can I use 1/2" CBU on floor?

So I have a small bath to tile and I have some 1/2" cbu left. Can I use it on the floor? Everything I have read on this board says to use 1/4" but I don't see why I couldn't use 1/2". I guess the only issue would be the transition from the tiled area to the non-tiled areas. The house is a new construction and the room outside the bath will be carpeted.

Sure you can use that. The only reason I would use 1/2 CBU for the floors if I needed the height. Other than that, return the 1/2 cbu and get the 1/4. The 1/2 doesn't add any structural integrity on the floors. Oh yea, make sure you put some thinset under the cbu when you're doing the floors.
