Tiling a space that flows into the home addition ....

As I alluded to, Im tiling a space that flows into my addition or home addon.

Specifically, the kitchen opens through a small doorway (minus door) to the addon. Theres concrete and small gaps right in said doorway for obvious reasons surrounded of course by plywood subfloor.

When I install my concrete board, do I use a patching compound on that gap to connect the two rooms? Am I screwed ?


P.S. - Im Tiling Dumb when it comes to installation tips and tricks

No, not screwed, merely challenged!

I'm assuming that your floor joists and subfloor meet the stiffness requirements for tile. If you are uncertain, we can discuss them.

First, check to see if the concrete will need leveling or flattening. Then verify that the plywood/backerboard floors will be level with the concrete. Assuming the levels are the same, install an antifracture membrane over the joint between concrete and wood. The membrane must be as wide as 3 tiles and be centered over the joint. Set the tiles on the membrane with a modified thinset, then caulk all the joints over the membrane with a color matched caulk, or better, a urethane expansion joint sealant.

An alternative is to leave a single grout line directly over the joint, then fill the joint with urethane sealant. This limits your layout, though, and interrupts the "flow" between your addition and the rest of the house. It will fall in the doorway, so it may not be so bad.

Ah - well , the only issue is that my fiberock will be a bit higher than the concrete in the center. Patch, and then membrane?

Thanks so much for the help
