Took out old ceramic tile that was embedded in concrete. Older home original tile. Now there is a big hao between the floor and walk 2 DIFFERENT sizes.Most of the Flor is 1 inch 3mm. There is another srip that runs behind vanity that a 2quot;. The new tile is small square and only maybe 1/4 in thick I d that.Is there 1quot; cement board? What do I do if there is a gap between tile and floor wall? I do t want water getting in from mopping or wet making mold. Also what do I do about the part that is a larger hao by 1/2 in than rest of floor? See pictures.
Well to start, I would prep the floor by thin-setting and nailing/screwing cement board to the floor. Use a larger trowel (maybe 1/4x3/8) to help bridge the gaps for a solid bond between the wood and the cement board. Afterwards, use a self leveling compound to eliminate any uneven gaps and to raise the floor level to high high you need it. If the leveler will run under the house from the gaps, use tape or other materials to keep it from flowing through. Use as much leveler as you need to make the height where you desire...and and easy job tiling with the new level floor.
