Out of date pre-mixed lime render

[chriseastlondon]

Hi all.

I bought about 8 bags of pre-mixed lime render a few years ago. The brand is Conserv. It comes in a large bag containing the sand and a separate bag of hydraulic lime.

In the end, I didn't use them. I was planning to put them on eBay or Freecycle. But I realise now that the manufacturer's website gives a shelf life of one year - so they're at least 3 years past that. If the lime is still powdery and hasn't gone solid, would they still be usable, does anyone know? Or will I have to just take them to the tip?

A couple of years ago I bought a 25kg bag of Conserv lime finishing plaster. I was dubious that sufficient lime (a 2.5kg bag if I remember rightly) had been provided, so I used the very fine sand with my own NHL. The sand won't have 'gone off', and if the much more costly lime is still powdery I'd use that too. I keep my NHL in sealed plastic buckets (as used for garden fertiliser), and in those it has lasted years even in an outhouse.

After my experience I would be interested in how much lime was included in your bags.
