We are in the middle of a kitchen remodel. We removed the old linoleum floors and there are wood planks that run north to south. Currently, this layer is flush with our living room wood floors. From the basement, you can see that there are boards that run west to east where the kitchen is.My question is, if I remove the wood planks that run north to south, can I put down a layer of cement board and just start tiling over the west to east boards? Will the weight be a structural issue? I would leave the north to south boards, but I'm worried about a tripping hazard being presented when I put down cement board, grout, and 1/2quot; tile (would probably be 1quot; all together). Trying to stay away from ramps, also. Thanks.
Are you saying there's 2 layers of boards on top of the floor joists? If yes then removing the top layer would be the way to go if the bottom sub-floor layer is strong enough to not be springy under concentrated loads or if you can beef it up by installing bridging underneath between the joists. If the sub-floor is the only layer then you'd not want to remove that since the structural integrity of the house would be affected and the cement board wouldn't be properly supported.
