PVA glue

[Hilly]

It seems that PVA adhesives of all stripes have a shelf life of 12 months.

Has anyone had pva adhesive sitting around for longer than a year without experiencing any loss in adhesion and bond strength? What's the longest you've had it sitting around?

Well, if you consider good old Elmers glue to be PVA, I've had a bottle for years and years, and it still sticks stuff together. Sometimes I wonder if the manufacturer says it has a shelf life just to make you buy more?

I bought the Wickes PVA that I'm currently using in April 2005, and it's still working fine! I bought it to seal and prime some fresh plaster when I was re-tiling our kitchen, but I bought far too much. I then realised its potential as a replacement for the more expensive UniBond, and I've been using it ever since.

I usually decant it from the 10-litre tub into a smaller jar, which I keep on the workbench. Occasionally a thin layer of water settles out on the top of the glue in the tub, but this reabsorbs with a quick stir.

This is great to know. Thanks.
