BATHROOM DESIGN & BUILD
John are you serious! Unbelievable. And people wonder why I have so many issues with Schluter.
Good on them for replacing the Ditra but ask Schluter for a better water ratio mix. The boys and techs from Mapei are not going to tell you to over water their thin set so you will need Schluter's help on this.
As for the best way of removing the old thin set try placing a wet rag over a section for an hour and then using your scraper. Before you layed the Ditra was there any places at all the cable heat was proud of the finished floor height?
How much thin-set did you spread when you layed the Ditra?
Is the floor heat on or off? Off is the correct answer.
Your bonding issue and the over watering of thinset is one of the reasons we don't use heating mats or heating blankets. I have heard of similar failures with the bonding issue.
I feel for you John. Sorry to hear that. Thank God you found it before you layed all the tile....
It might be a good idea to lay the next round of Ditra down in smaller sections - say 3'x3' squares.
Did you roll the Ditra? Did you walk on top of it while installing? How strong are you? How much do you weigh?
When installing Ditra, Kerdi, Tile, Noble, Wedi and anything that requires thin-set remember that you need to check the coverage rates. Lift up the Ditra and check the coverage, then re-set it.
