Question? When are you checking to see how well it bonds? If it's while your setting it, then your pulling up wet thin set and you can only see if you have 100% coverage,not bond? If it's after the Ditra has dried,then your
ruining the piece anyway BY pulling it up?

Isn't the idea to BOND the FLEECE backing? Then a 11/16" V-notched trowel like Schluter says ,with the correct consistency thin set mix , will be fine. It's
just as important to be sure you embed the material into the wet thin set. You
can see the color change when you do.

Ditra trowel, right tool for the job, though I do not like the ergonomics of the Karl Dahm trowel handles, over 100 feet and I'm getting a blister. Marshalltown should make one.

Levi, by the time you have your helper beat the snot out of the thing and clean up the ooze, you'd be saving money getting the right trowel I think.

used a worn, 1/4 x 1/4 for a long time, worked ok, but the trowel is worth it, imo.

And like Phil said, you can see the color change, except for the time I added orange food coloring to the thinset.

Yes 11/64, guess I'm due for new glasses. The 4.5mm's is correct, which is smaller than the 1/4 X 3/16. I've never used anything other than the 1/4X3/16 with no issues, same goes for Kerdi.

Levi, I would think those smaller trowels would pay for themselves in thinset savings after a short time. Just thinking. I love the 1/4x3/16.

Another thing while I'm thinking about it. I still dont understand why folks wanna pull Ditra up to check coverage. Get the thinset down evenly and lay the Ditra down quick, before it skims over, work it down good with a 2x4 and its done. Why the heck would anybody want to peel it back after all that?

Ed, I peel back a corner after every new bucket I mix just to make sure my thinset is the right consistency. I don't want to be one of those guys calling tech support wondering why the fleece wasn't sticking to my dry mud.

I have gotten lazy and find a floor roller to be easier to embed the fleece. I don't push hard, just hard enough to do the job. I seem to be able to move along a lot faster and feel less tired. Which is one of the big reasons I choose Ditra over backer board.

I use a wood float to embed it.

I lost my wood float and I'm too cheap to buy another one, so I use a two-foot length of two by four. I lean on it with both hands and move it around. Good exercise.

But let's try to stick to trowel size. I use to use a worn quarter-incher, and I would still recommend that to diyers, since they probably can't get a Ditra trowel.

Now it's the Ditra trowel for sure.

I'm with you Brian on the roller. It embeds the ditra easier and thus the trowel size doesn't need to be increased.

Who buys Ditra/Kerdi trowels? I still have a few un-used ones.

I own the Ditra trowel but mostly use my 3/16"x3/16" square notched trowel which is just 1/64" larger then the Ditra Trowel and has an angled front edge which makes it nice under cabinets.

Paul, I use a Schluter Ditra trowel. 11/64 x 11/64. First time I used Ditra I bought it a tile shop where the real tile guys go. It was 20 bucks. It looks better made than a ten dollar trowel made in China.
I used Ditra because the joists were over spanned and didn't trust Durock for that job. I asked the pro's what I should do.
Salesman sold me the modified and un modified,with an explanation why , sold me a trowel with a explanation why, and told me to make my thin set thinner than peanut butter and roll it with a rolling pin with pressure. I didn't have a rolling pin so I used a small linoleum roller.
He didn't tell me to check if I had adhesion . I noticed a solid grey background wherever I rolled and figured thin set was locking in.
Customer has commented how solid that floor feels and sent me work from their friends.
It's nice their other bath has one layer of ply, durock,and white washed grout where tile meets tub, to compare my job to.
