cheers dave

so this type of notched trowel, that leaves a sub base of adhesive with a groved layer above it does not exist?

regarding the floor thickness, there is half inch ply, then I screwed a 6mm ply ontop, but there is height issues with a hall way. what would you of recommended as I did a post about using ditra matting for this, but you and wivers replied that if i beefed the floor joists with noggins which I have done it should be okay with a flexi adhesive. do you think i should use a two part bal fastflex adhesive instead of the nicobond rapidflex?
