I've got to strip kitchen and bathroom walls down to the brickwork, they're both going to be tiled but the bricks going to be a bit rough and I reckon I need to level it first, what's the best product? I had assumed just a layer of soft sand render would do (don't work with masonry much) but then I started reading about dedicated wall leveling compounds and bonding plaster and I'm getting confused, could anyone point me in the right direction? I think the biggest troughs in the brickwork will only be about 15mm max.
Cheers.
