repair wall to a paintable finish

[artwork]

Hi Everyone

I've removed some old plaster and render from a wall that had penetrating damp from a neighbours broken pipe 10 years ago - its all dry now.

Here's a video of it



I'm intending to render the brick work in two coats. What should I do with the old basecoat plaster thats on there ? Its hard to take off? If I scored it will the render stick on there as well? I have about 22mm of space to fill before I apply finishing?

Any other tips appreciated..

Thanks

Andy

Also can I put bonding onto the old plaster as a basecoat for finishing?

Will I still then need to key the old plaster?

thanks

I'd be using renderlite made by Sovereign as a base coat, stop any old salts coming through.

Hi

Last Thursday I put a 20 mm render 4:1 - Plastering Sand:cement - over it.
How long do I need to allow for drying before skimming?

Here are some photos of the wall today...
