    Default Selleys Aquadhere exterior shelf life

    Anyone know the shelf life of this product?
    I'm out of glue and need to re stock. I've used Titebond iii exterior on almost all furniture I've made (chairs, dining table, side tables, etc) and are happy with it. The Titebond website also provides datasheets which list the shelf life of 24 months.

    Selleys on the other hand don't have the same approach to sharing technical information and I cannot locate any data re shelf life.
    I can buy the Selleys locally (a 5 min drive) but the Titebond is only located about 40 mins drive away so provided the Selleys Aquadhere exterior is of similar "quality" to the Titebond iii then the Selleys would be a good choice.

    Any feedback welcomed.

    Most glues have a shelf life of about 24 months, but this is heavily dependent on how it's been stored.

    If it still pours and isn't lumpy its good in my opinion. If you're concerned glue some scrap together and test.

    Contact Selleys through their website and ask the question, I have done on several issues and they have always been very forthcoming.
    I have used Selleys in both standard and outdoor for many years and never had a problem.

    I dont know what the official shelf life is but I must have gone over the two years with a couple of bottles as I just use them until empty. Never had any problems with it. Like you I can't get titebond lacally but I would not rate titebond any better than Selleys. We watch too much Americian woodworking. As said storage will be a factor and I have noticed on the UK forum people saying that PVA goes off in below zero storage.

    Yes, the glue won't be stored in cold temperatures so it appears from the feedback here that Selleys would suit.
    Thanks for the replies.

    I've found a few bottles of old Selley's Aquadhere exterior in my cupboard recently. Went a kind of clear brown, very viscious, and very acidic/vinegary smelling. They would have been in the cupboard for at least 3 to 4 years I reckon. I think if the glue still smells like normal PVA glue (not very acidic), looks like normal PVA glue (white), and is running enough to wet and spread on the surface you're gluing, it should be perfectly fine.

    To add, I recently enquired with Selley's on the working/open time of Aquadhere Exterior and why they recommend coating only one side. I couldn't find any information online, but plenty of people asking and wondering about it. Here's what they said:


    If applying glue to a highly porous surface we would suggest to apply glue to both sides allow to soak in before applying a second coat to one side only this will result in a stronger bond. Applying the correct amount of glue to one side only will be sufficient in most cases, you can apply to both sides but there is a chance of excessive waste"


    The working time is approximately 10 mins before you may have to clamp do not stress for a min 12 hrs. Clamp for 30 min for soft woods and 1 hr for hard woods. Max strength after 24 hrs.
    So basically, the recommendation to coat only one-side is based on the fact that normally a generous coating on one side is enough glue. There's no advantage or disadvantage one way or another, it's just about getting enough glue on there without wasting too much of it. I thought maybe it was to avoid air entrapment or something more technical, but that doesn't seem to be the case.

    We have a drinks fridge on the back veranda and these days, as I don't drink, it's increasingly used for things like adhesives, gap fillers and sealers and lost of chemicals eg my home made hand sanitizer, anti rust chemicals etc. Stuff lats a lot longer. I get 8 years from a tube of well sealed Silicone sealant. PVA glue lasts for >5 years.

    BTW Thingiverse has 3D printer plans forand screw capped stopper that is very effective for most calking tubes

    When I was at uni we did some testing of PVA on a range of surfaces:
    • PVA on flat side of MDF - it essentially just sits there,
    • PVA on edge grain of MDF - it quickly soaks in and disappears,
    • PVA on quarter sawn messmate - it essentially just sits there,
    • PVA on end grain messmate - it quickly soaks in and disappears,
    • PVA on highly figured back sawn messmate - it sits there on most of the surface, but is soaks in and disappears in parts of the figure.

    Conclusion: Some parts of a timber surface are much more absorbant than others - those sections may result in dry joints. If you wet both surfaces with glue then you will almost totally remove this risk. It is such an absolute pain to recover from a dry joint, then why take the risk, even when the risk exposure is only 2-3%? The solution is just a coat of glue on the other surface.
