Re-rendering internal walls in terraced house

[Sevoris]

I am renovating my Victorian terraced house. I knew I would have to replaster, and maybe even fix some of the render due to removal of walls, but I then noticed that much of the render is blown.

The house is a brick & stone construction with walls originally rendered with sand & cement, using mining coal in some places. Survey showed no obvious damp issues with this approach.

As I am now looking to remove much of the render I am wondering what the best approach is to re-render before I plaster.

I've had advice from some plasterers, who recommended sand & cement, as originally done, so I want to sense check that.

Should I be using special additives or not, both with render & plaster?

Attaching some photos of the walls.

Gaps in render are due to walls being removed and space made for a later rsj installation, apart from the one showing the light switch where the render was blown so it came away in chunks.

PS: photos are flipped for some reason...

I would be using sand and cement Unless I was hacking it all off then I would hardwall it

You will be luckyto find plasterers that can float and set these days.

Not sure on the age of the building but in the Victorian era it'd probably be sand and lime mortar to be honest. Cement was sometimes used.

I'd try to avoid pure sand and cement mixes if poss. The mortar make up and the design of the building originally was breathability and flexibility for lasting the age.


Cement counters both.
Cement is faster and slightly cheaper, but no where near as good.

Sand & lime mortar for the render, and then regular plaster over that? Or something different?

It depends on you and what you want....
What you want to achieve.....

If you don't care about breathability or flexibility, top with anything, multi finish, board finish etc.

The original would have been lime based.
Lime skim. Many companies now offer decent products that are easy to use.
