Slate tiles again here. When putting underfloor heating (electric) on to Marmox I was going to put down self-leveling compound to hold mat in place and to stop me nicking a cable (it's Teflon coated but I'm not a tiler!) I've been advised that I should use flexible adhesive instead as slc is too rigid (the marmox is fixed down to ply). Does this sound like a good idea? And which adhesive do people like these days?
