We are going to remove the vinyl flooring. It has a 1/4in sub floor over hardwood.
Are you saying hardwood and not the ply wood sub floor? You can t go over hard wood with tile, even with a backer board.There is to much movement and expansion and contraction . Must remove this too. Now if you mean sub floor then yes it s very important that you do cement board ( 1/2) you need this total thickness in substrate to meet tile codes 1 1/4 minimum.This must be layed properly in a bed a thin set and nail well. Any other questions you can e mail me thru my avatar and check my qualifications there GL
You need 1/4 hardi board at least the seams will crack if the floor moves at all. I did a bath and there was one small 4 sq inch depression and the tile broke right at that spot in less then a week.I would say yes .I am not a pro tile man but a pro DIY guy
There are tens of thousands of ceramic-tile installations all over the world that are hundreds of years old that are still in great shape. Almost all of these are installed directly over concrete or somecement-based material If you want a gorgeous ceramic-tile job, you need to be sure the backer board is in the same plane and the walls are perfectly plumb. In the old days, the tile setters installing the wet cement stucco took the time to get the stucco perfectly plumb and flat, even if the wall studs were crooked, bowed or bent. for other information you can check my source site
