[left]Hello- I am looking for advice on how to slope tile for a threshold. This is for a flooring transition from tile in a dining room to bamboo flooring in a living room that has a 1/4" height difference. I need the floor to be barrier-free and as smooth a transition as possible for wheelchair usage. I removed a bulky wood threshold and want to replace it with small tile for a slightly sloped smooth transition. I plan to remove one row of existing tile to make the slope more gradual and will have about 7" to work with. My question is whether or not I can create the slope with thinset as it is only 1/4"? I have photos but am not sure how to post them on this site.[/left]

I installed the Ditra uncoupling membrane over plywood and wondering if I should redo it. I mixed Mapei porcelain tile modified mortar so it very slowly dripped off the trowel. After applying mortar to the plywood, the coverage on the back of the Ditra membrane was 80-90%. I think I should have added more water to the mortar and reapplied it so it was more watery and better penetration into the Ditra backing. I didn't do that and pressed the Ditra back into the mortar and let dry for a few days. I tried pulling the Ditra up from a corner and it peels off but takes some effort. I called Schluter and their field rep said that even done perfectly, the Ditra can be peeled off. I described what I did and he thought it should be fine as long as I can't pull any of the Ditra squares straight up, which I can't. I don't won't to redo if unnecessary but thought I would check to make sure before proceeding with laying the tile. Thank you.
