I plan on installing ceramic tile in the kitchen. We removed some old flooring and installed a new plywood subfloor, then plan to put backerboard on top of that for the tile.
The house is older (1940) and is built on a ledge and one of the floor joists rests on a portion of the rocky ledge the house is built around. All the remaining floor joists settled slightly over time but this one stayed rigid.
So I'm left with a very slight hump running horizontal across the kitchen. We're talking about less than a 1/4" gradation across the hump (not visibly noticeable but you can tell with a level). Will I be ok putting tile down or do I need to level?
And if I level, does that mean using self-leveling compound on the entire floor to raise the rest up to the apex of the rise? Am I better off instead sanding the plywood down to try and level off the rise?
