Lime and snow

[chapel]

Hi folks,

To cut a long snowy story short...two 20kg plastic tubs of ready mix 3:1 were left outside in the snow (we had a foot here in kent!). I've had a look inside this morning and there are ice crystals inside.

Will this still be ok to use?

thanks all

My understanding is that it isn't a problem at all. It needs to be thawed out before use but nobody would use it frozen anyway.

Mike Wye stores his lime putty in an unheated barn for 6 months (?) before selling it so it can't be a problem.

It should be fine. It will look / feel a bit grainy when it thaws, but it will not have gone off. This will disappear when you knock it back up

I've got a couple of tonnes of premixed 3:1 that have endured a couple of winters now, with the lowest temperature so far being -16. It knocks up to a lovely plaster once defrosted.

Ace, thanks all

I have just bought 4 tubs of SWPS 3/1 Unhaired from Mike Wye (which was made up and shipped on the same day last week) and it clearly says on the tubs "Store free from frost".

That's more because the tubs can split if the contents freeze, and the plastic becomes very brittle. The lids snap like dinner plates when it's very cold.
