Any plasterers about?

Does anyone know what the minimum thickness Dot & dab plasterboard can be applied.

I've been knocking tiles off the bathroom wall and the old plaster was loose so I've knocked half the wall down to the brickwork, the plaster on the other half is rock solid but only about 20MM thick. Will I be able to dot & dab the bare half to match up with the 20MM thick plaster? The door is tight up to this wall otherwise I would just knock it all off.

Would I be able to apply the bonding to the wall with say a tile adhesive trowel?

I'm assuming I need to PVA the bare bricks? 5 to 1 mix?

Thanks in advance for any advice.

I would say no problem there mate, done the same thing myself and never had any problems. Just use as much stuff on the wall that is required to get yer levelness. Don't know about the PVA mix ratio like.
 
no problem with doing the wall mate just use the 4x4 handy boards mate pva the wall then stick the dabs of board adhesive on the wall them push against the wall but not fully home then use a straight edge and tap the boards flat along the length of the wall across the already plastered part and the board so as the wall runs straight from the plastered part and along the board length if that makes sense
 
:D I was fully expecting you to suggest I use that stuff, what's it called again?

Been working hard today, removed about 8 rubble sacks of tiles and loose plaster, plus the bag full I've inhaled. :D

Yeh, they've got to be parrallel but a couple of mm back so you can apply the final skim of wall finish to the new boards so it finishes flush with the existing plastered wall.

was assuming hes just tiling over it again so that was the easiest way of getting a flat surface so he wouldnt get any lips on his tiles
