Question about Mk Diamond 154861 MK-100 7'' x .060'' x 5/8'' Diamond Blade
I know cracks in a basement cement floor can and probably will work up into tile applied over them. Can I use sheets of cement board and not attach them to the old floor, like a floating floor? Bond the edges together then set tile on top. This would allow the cracks to widen in the old slab and not affect the finished tile floor, possibly?
You can get a crack membrane to put over the cracks. First use a primer on the floor, this is a primer just for this application, then put membrane on top of primer. these products can be found at home depot or lowes or any tile store.Also do not use cheep thinset. the better thinset is more flexible and will absorb any movement. The cement board would not work as they will move or flex and cause the grout to crack and tile to loosen
