Hello,

I am currently gutting my bathroom so that a tiler can install new tiles. I have now removed the old tiles – is this what it should look like?

What type of tile adhesive was used here?
Does this need to be removed as well?

This layer is about 3 cm (1.2 inches) thick, and behind it you can see brickwork.

Which demolition hammer is best suited for this? For both wall and floor? 3.5, 11, or 18 kg (7.7, 24.3, or 39.7 lbs)?
