Can I use a fast set to level off then use normal set top of that.
It will be tilemaser stuff that says upto 12mm so on the level side it will be whatever a 10mm trowel creates but on the lower side it will be 10mm Plus the trowel depth. So if the fast set has gone off a little does that count as being a thick bed - too thick and lead to the below pul back.
My plan is to work on a couple of rows at atime so my the time I have done the first row the second row fast set has gone off enough to stand a little pressure of the trowel.
I don't fancy trying to use thick bed addy. Came across this when searching
you can use thickbed adhesive, but to be honest its not easy to trowel different thickness and keep the floor free from lippage, addy at differant depths can pull back when drying causing an uneven tiles
