EasyMat Tile Underlayment & Stone Underlayment
The general recommendation is that the total thickness of the subfloor under tile be a minimal of 1 1/eight″ thick. So while 5/8″ plywood topped with half″ cement backer board can be okay, half of″ plywood can be a bit on the skinny side which could trigger problems with deflection. Also, remember that backer board doesn’t provide a lot precise help so far as deflection is anxious. My subfloor is made from 1 x 8 planks with approxiamately half″ to 1″ of hole between every plank.
I have to build up the floor to fulfill the peak of the three/4″ hardwood floor in the dining room. Would applying 1/four″ cement board with 1/4″ tile, together with 1/8″ thinset underneath the cement board and 1/eight″ thinset underneath the tile, do the trick? Should I rely on thinset when determining the height of the ground?
