PVA, SBR or nothing at all?

[Slippery]

Hi,
I'm a multi skilled carpenter with 27 years in the trades, I do a bit of plaster skimming but have never done any rendering.
I'm repairing hollows in the render of my 1894 Victorian house and have tried to find as much info as possible before knocking off.
So far, I've gathered that I should use a 4:1:1 sand cement and hydrated lime mix with waterproofer in the base coat but I get conflicting views on whether to use PVA or SBR or just wash the bricks down and render whilst still wet.
Personally, I get the feeling that PVA should be used but don't want to make things any more difficult that they are already.

Any advice please?

TIA

Your mix is wrong for a start = recipe for disaster!
Just hire a local and well recommended plasterer and you can rest easy back to butchering wood.

Pics would help

If it's 1894, probably a lime mix


Understand that the sand and cement mix (with lime) you describe is NOT a lime mix.

Just so you know and before it cracks where they join each other.

One moves, one don't.

Not that helpful!

Would be more helpful with a suggestion of what you would recommend!

No, it's sand and cement, at least on the two top levels, I've not inspected the dashing below yet

I've had enough experience paying people to f**k things up on my houses, I do my own work unless it's impossible. Nobody available locally anyway.

I'll try get some pics up

I already left, I was looking for help but found a site full of Prima Donna's and people thinking they are some kind of genius because they can spread muck on a wall!
Thanks but not thanks at all!

Did you take my advice and hire a professional plasterer?

They’re out there with lots of bills to pay.
