Hi I had this house coated with this wonderful stuff some years ago, but
have recently removed a fitting from the wall and need to really block up
where its bracket was. When it was done originally, it had some kind of
binder put on the render first. I still have a little bit of the toop coat
left, but wondered if this would even stick or peel off. The advice I've
had so far is just try it or use some other outside paint of a similar
colour.

Most of the masonry paint manufacturers make some sort of binder for powdery or porous surfaces.

Google "stablising solution". Lots out there.

Another thing you can use is a bit of waterproof PVA, diluted down a bit.
Cheaper than buying a five litre can of stablising solution
