So I should used un modified thin set to stick the porcelain tile onto the ditra. Even though you are suppose to normally use modified to stick porcelain?

Yes, unmodified over Ditra. Modified would be okay if you wanted to allow extra days to dry, but unmodified will work. Use the flat edge of your trowel to skim a thin layer over the back of each tile immediately before it's set.

Steve, if you'll add your first name to your permanent signature line, where you have the numbers and letters, it'll appear on every post.

I am trying to edit my signature line. but that sounds good. I was told from my tile supplier they sell mapei ultra flex 1 and ultra flex 2 which are both modified to stick ditra. does it make much difference on what bag I use. flex 2 is suppose to have more polymer added for extra stickyness. will ultra flex 1 work well enough also?

Yes, Ultraflex 1 will be fine.

Great choice. I looked that other product up and was not impressed by their website that was peppered with mistakes.

I was at a job site today and noticed the tile guy installed the ditra under layment. I took a couple photos. I notices he skimmed the ditra with a layer of mud and he left it to dry so he could come back a different day to set the tile. What is with the skim coat on top of the ditra? all the info I have seen everyone just starts setting the tile right onto the orange side. Is there any reasoning behind this? is it necessary? also I took a photo of the bag of mud he used. It appears to be a modified thinset? I guess it is what he used to stick the ditra to the plywood and I assume its the same stuff he used for the skim coat. any feedback?

It seems pretty common to go ahead and use the extra modified from laying the ditra to fill the waffles. Less waste and less pushing thinset around when you are trying to lay tile.

I guess the process has been okd by schluter as long as you give it time to dry.

how necessary is this to do? and would I use the unmodified to set the tiles even tho I used the modified to fill the waffles? Is the advantage just to fill the waffles so you are not spending as much time trying to fill them when setting tile?

It's not necessarily and probably not really preferred.

Yes you would still use unmodified to set the tile.

It's just to make less work later. It's also fairly convenient as it doesnt take much to set the ditra so you are likely to have leftover. It also makes snapping chaulklines a little easier.

ok for sure snapping a chalk line was a concern I had as I have never worked with Ditra. sorry for the excess questions I am just trying to make sure. so I would use the modified to fill the waffles if I decided to do it that way?

Mud it

See my earlier post today. 3/4 inch thickness of tarpaper and wire and mud bed over the high spot is more than sufficient for a lifetime floor. Make sure the installer is actually fully competent in laying a mud floor and have him do the job.

would you mix the thinset a little on the runnier side? to help fill the waffles? also what is it like trying to snap a chalk line on the Ditra? I heard something about hairspray. what works?

They show in some of their videos that you can spray the chaulk line with hairspray to make it stay.

I'm sure you could do it with unmodified too but most people have extra modified mixed up from laying the ditra.

It really didn't work at all for me to snap chaulk on ditra. I used a sharpie and a long straight edge in the one room i didn't prefill the waffles in.
