Hi all,
Just a basic tiling question. I am re-doing the kitchen floor, and am planning to use 1/2 thk Hardi-Backer board for the sub-floor preping (I used it before for a shower stall and works nice - with 4 mil poly...) and I was interesting in knowing a couple of things:
1. - is it necessary to remove the existing vinyl floor before screwing down the backer-board?....there is 3/4 in plywood underneath
2. the subfloor has settled now, and there are some shallow troughs that will be spanned with the backer board. Has anyone heard of any 'flexing' issues with hardi-backer board that I missed?
3. The building codes are standard residential for Pennsylvania...I don't believe there is a weight issue, but it doesn't hurt to ask....
Any response is greatly appreciated....and any tips are always welcome......
