What lime to use in fireplace render.

[RA83]

Evening all.

I have a fireplace that needs rendering before a woodburner goes in. Have been advised to do it in a Lime render. Which lime do I want, hydraulic or hydrated and what’s the best ratio to mix it in?

I was going to use cement boards but the inside of the fireplace is too rough and would need rendering up first to take the boards, hence the advise to use the lime render instead and save some work.

Many thanks

I had a bag of monochrome render over from a job. High lime content - cream colour, used it on a surround, went in nice.

Not sure if he was going to paint it or not. Looked tidy as was.

3:1 - scratch fibre, float fibre. Make sure the lime is complete cured before using the burner.
