Title: Old plaster?
Post by Natedog on Nov 6^th, 2024, 9:57pm

Am I likely to run into any problems using plaster that is a couple of months past the use by date? I'm going to be doing a bit of plastering next week and I've acquired some thistle multi finish that's between 2 and 6 months past the date. I'm thinking it's probably OK, particularly the newer stuff?

Depends how it’s been stored but it’s only normally safe to use just a couple of months past its date. I was given a load a plaster for a job and it went off so quickly it ended up a disaster. Conversely if the plaster is a bit older it doesn’t go off for ages. If in any doubt buy new, it’s not worth the small cost saving for the amount of hassle should it not cure properly.
