Old Plaster?

[Swiss Tony]

I know that plaster goes off after a while, but how long should it be before I throw away a couple of bags of bonding that I have. Probably 3 or 4 months old now. Need to get a load in a few weeks time so can I use what I have or buy new?

Bags unopened if that makes a difference and kept in the hall.

you wont know until you start using it and for the sake of a couple of quid i would throw them.

Offer them to a gardener with a heavy clay soil, gypsum breaks it up.

Take them back to Mountfield.Nr. Hastings and chuck back down the mine ...we`ve all got to re-cycle
