Hi,
Would anybody know if I can still use Natural hydraulic Lime NHL 3.5 in white powder from unopened bags I bought 18 months ago?
A bit of a delayed project, which is to plaster in and around my fireplace. Lime, because it is apparently more fire resistant than cement.
The bags do not have manufacturing dates or use by dates. I was originally told it would last but have now heard a different story. The manufacturer cannot give me a straight answer. So I have done some research and I'm now quite confused. One website says it will keep for 4 months and goes even further quoting that once a bag is opened to use it within 3 days and discard what's left afterwards. Should this really be the case?
I would really appreciate if somebody could enlighten me.
Thank you.
