Didnt these old houses have tile "successfully" back then also? Okay - so a grout line cracks 5 years from now - Is repairing that when it happens cheaper than me basically dismantling my entire house now????
You would be lucky if only the grout lines cracked. The only other way to lay tile is on a slab or pour the floor. Cement board is the "2000's" solution for not having to go through the nightmare of mudding the walls and floors.
I do this for a living and would NEVER, EVER tile a bathroom or anything else on wood. The extra 12 bucks a board and half day of labor wont kill anyone.
Lawyers and accountants dont care if your house falls apart because you did it wrong, its all on you. Just dont expect to have someone that knows what theyre doing to agree with doing it wrong. Thats like asking a welder to use crazy glue because you saw a guy hang from an I Beam on TV.
Glenn... If you have seen someone use mastic or thinset directly on wood, in any decade....you have seen someone do it 100% wrong. I shiver at the idea.
