Just joined the forum and read that bonding and finishing plaster should be done within an hour or two. I need to know this is a very small area which I had knock back to brickwork. So for the bonding do i need to add a waterproof and SBR ( SBR on the
brick work) Also because it is such a small area can I just make my on bond mix ie plasters sand and cement; what mix please

Hi to all readers. Thanks for the sensible comments. Just would appreciate exactly the right mixes please. Ps it’s a very small area. Can I do a premix before a finishing plaster
 
Why not board it? I wouldn't use hardball or browning on an exterior wall personally, s+c if you can't board it........although I don't really know what your talking about either

Hi Richard, I chipped away plaster just within a patio door ; over the years/mould set in and the plaster started to crumble. Again I chipped to the brick work ; and now I just want to know the best way forward

The wall is not external. The area in question is internal brick wall in a conservatory. It is a small area about 2 foot from the floor
 
Make sure theres a dpc between your door frame and wall, you can't have the inside meeting the outside, if not, expanding foam, then bit of waterproof in s+c, then skim

Morning Richard,
Thanks for your advice. I have attached a photo to show you how small the area is. This is why I was hoping having to buy 25 k of an undercoat plaster. All I want to know is do I have to SBR the brickwork (inside the patio door prior to starting some kind of base coat. Will await your answer and time

So what you mean is put a piece of 9mm board (plaster board) ?.? The beading has to be bonded and also I would need to build up (with what ?) before doing a finishing skin.

You're either on the windup or way out of your depth if you think 20mm is "just over a half inch".
Either way it's made me smile.

Dot and dab easily, 9mm board, 1 bag bonding compound, 1 multi finish and a dry wall angle bead

Hopefully I can move forward. The walls are dry - I received a replay from Danny
