That's the question? I am doing a floor and part wall - 4sqm each. Shall I get a 20kg bag of Bal PTB flexible adhesive for the floor, and a 20kg bag of the BAL Single Part Flexible adhesive for walls, or will 2 x the first be ok? I am tiling with slate.
and for those of you experienced with Bal products - will i need to use a bal primer before adhesive? (Tiling onto ply and hardibacker). I am ordering online so want to get it all in one go.
BALs coverage figures are a bit optimistic, though does depend on what size notch and how uneven the slate is, I'd get two bags for teh floor and one for the walls and use singel part flexi or rapidset flexi on the walls.
No need to prime either surface.
Not used the aquamix, usually use Lithofin sealers.
