I've read through Jimbrian's postings about his asbestos work, and got a lot of good info from it. I have already removed my tiles and now am looking at how to handle the cutback. This is for my small bathroom 4' below grade on concrete floor, I live outside of Chicago.
I want to install radiant heating, and am wondering what order to layer everything. This is what I have come up with so far
1.) Wet-scrap cutback as much as possible.
2.) Skim-coat Ardex feather light to seal in and make bondable surface
3.) lay down and secure radiant heating matt to concrete floor.
4.) 1/2" modified thinset to enbed heating matt (Would like to use SLC but can not find reliable info on if SLC will correctly bond to skim coat of Ardex.)
