Can I lay tile on luan?
I have been reading as much as I can about laying tile but I am still confused.
We put new luan down over the old sub-floor in our bathroom. The surface is now clean and flat. The area to be tiled is 5x7. My dad (who has layed tile several times) said I could tile directly over this floor but I have read in some book that I need to put cement board down first.
Which is correct? We will be using 12x12 and 4x4 ceramic tiles.
