Uncoupling membrane vs no more ply, when & where?

[Flintstone]

What do you class as a difficult substrate?

I didn't use the word difficult . Tricky , bouncing timber floors . Floating floors , walls with hanging plaster . Pretty much much anything that I have to put work into to bring it up to a standard that I will be happy to tile on without it failing I regard the biggest enemy of a tiler is a moving substrate .

I always use 6mm Hardie to over-board a timber floor, glued & screwed. I would only use an uncoupling membrane if I was fixing stone or on to a newish screed. Keraquick on every floor.

What primer you use (if any) on timber/chipoard floor before putting hardie down ?

Anyone use this stuff before Kerakoll.com - http://products.kerakoll.com/catalogo_dett.asp?idp=6966

I umm "inherited" a couple of 80m rolls that were over ordered on a subby job I was on, I find it alright, used a lot of it now never had any issues

Can i just point out that tilemaster mat and BAL rapid mat are not single layer construction. Both offer far more than single materials such as mapeitex etc.
