I always do solid sills for curbs. you can get leveler to pour over the heated mat make sure you foam all the corners, door ways and any place you dont want it to go. it basically a thin slurry when you pour it and it runs EVERYWHERE! I always use Durock. I hate Hardi backer.
Here is your answer. He thinks it is fun. Hire him to come help for a day or so. While you are at it, give him Kentucky Bourbon and a day or two riding motorcycles....and he may do it for free.
I used something similar. Put cement backer board over the entire (wood) subfloor first, then laid out the mat. When the layout was dialed in, I hot glued the mat down to hold it in place and troweled the thin set over the mat. It is a pain in the a$$ troweling over the mat for sure. And I found out the hard way the thermal probe is THICKER than everything else. Was tough to get that tile leveled. For dang sure use the audible continuity tester while you are laying the tile, cause if you cut a wire and find out after all the tile is set, you'll want to kill yourself.
One more caution...the pour in place leveler is intended to do what the name implies...level. Your floor can be flat enough for tile without being level.
No doubt! I'm not optimistic enough to think it's gonna be "fun". RD- if working on Triumph electrical issues is also on your "fun" list please come on over! My Tiger 1050 has been sitting for a couple months cause I'm sick of working on it.
Truth be told, if he lived close to me I would give a hand. And yes, bourbon would be required Come to think of it, I owe Tristan because he found my latest motorcycle for me
The Bandit in Georgetown. Sum bitch gets down the road like a scalded ape. Been a while since I had ridden a big inline 4. I like it
I broke all the tiles up, and then saw how much work/time it was going to be to tile, and then hired someone to lay the tile down.
