Default Re: Gorilla Glue: your experiences & opinions

So far as I know Titebond hide glue is a hide glue, Titebond, Titebond 11 and Tightbond 111 are pva with different properties:

Titebond, Titebond 11 and Tightbond 111

Titebond 11 isn't a type 11 version of Titebond hide glue.

Thanks for that. It looks as though that seller has mixed up the information for the various Titebonds. I have sent them an email.

Arrow Re: Gorilla Glue: your experiences & opinions

I've now completed my experiments with the type of Gorilla Glue (GG) which I have previously mentioned. For a general adhesive for wood - usually PSE pine or redwood - I have always used PVA. So my experiments were a comparison of those two adhesives. I made two samples of a halving joint, X-shaped, using pine. In summary, my conclusions are as follows:

1. In terms of 'retaining strength' - i.e. how easy / difficult it was to pull the joint apart by hand, PVA won easily; the GG was weak in comparison. Both test samples were left for 48 hours for the respective adhesive to cure, prior to that test.
2. In terms of removing excess glue that has squeezed out of the joint - when the glue has not set, the PVA was easily superior to GG. OTOH, once the glue had set, to remove excess glue, there was no clear advantage of one adhesive over the other.
3. In terms of ease of removing excess glue (prior to it setting) from hand and clothing, PVA was very much the clear winner.
4. In terms of anticipated shelf life (including taking necessary precautions to maximize shelf life). PVA was preferable. This is based on the stated requirement with GG that the remaining air in the bottle must be squeezed out, prior to refitting the cap on the bottle's nozzle. Remarks in above posts (plus those read elsewhere) imply that if that is not done, the GG will self-cure in the bottle, thus rendering remaining adhesive useless. OTOH, yes, PVA will eventually become thick and difficult to use, but over a much longer time period - typically several months: much longer of kept in a container with a tight, well-fitting lid, thus preventing air intrusion. And even if the PVA has become thick, it can have its viscosity easily reduced by the simple expedient of adding tap water and thoroughly mixing it with the thick PVA. I know of no method / product for a similar procedure with GG, but acetone might be successful for that application. (Obviously, acetone is substantially more expensive than tap water!)
5. In terms of cost, per cc., PVA is more economical.

So for me, I will continue to use PVA for constructional joinery in softwood.

Al.

Don't wipe off surplus PVA when gluing if you intend to stain the wood afterwards, best to leave it till it's "just right" then either peel or pare off and finish with a quick light sanding if needed.

Thanks for telling us your findings Al. All too often we have long threads that come to no conclusions at all.

Yes, agreed: the latter part of your sentence is what I usually do - if staining will be subsequently required. Recently, all my woodworking projects have either been for the garden, so items have been subsequently painted, or internal repairs to the structure of this house, where the wood will not be seen or if it will be, then it has been painted to match its surroundings.
Finally, thank you for your comment.

What Bazz says - thanks for sharing your findings so meticulously, Al.

Without wishing to contradict you (this doesn't,) the yellow adhesive version of Gorilla Glue is fantastic at joining all sorts of things together that would otherwise be problematic. The frothing property adds volume and gives form in a way that can hold 'difficult' objects.

For example, I glued 4 x 1uF metal-canned oil-filled capacitors to a lexan base and together, and I glued the lexan base to wood with a very pleasing bond. The result was really sturdy and the ugliness of the froth wasn't on display as the result was hidden away.

It would have taken a small fortune in epoxy resin to achieve the same result.

....and for so very many things, where would we be without our 1.99 hot-glue guns

Gorilla Glue (the various types); PVA; hot melt glue; Araldite (and its comparables); 'Evostick' (again including similar products); 'Superglue' (cyanoacrylate) and other adhesives mentioned in this thread: we are spoilt for choice! Seems to me that it is a question of choosing the appropriate adhesive for the task in question - and that choice is simply made by recourse to personal experience gathered over time - like so many 'Can I fix this / how does it work?' questions that we face in our hobby.

When they manage to produce a glue for polythene, success, that would stick everything.

Hot melt is the only thing I know of that works well with polythene.
It is basically low melt polythene.

Very true! I can just about remember when the choice (for DIY, at least) was pretty much limited to hide glue, Seccotine or Copydex. Bostick and Evostick were revolutionary when they became available.

I know that PVA doesn't stick to polythene but when I come to unscrew the cap on my 5L polythene plastic container, I have to either use a large pair of Stillsons on it or clamp the cap in the bench vice and turn the container to remove it.

I have no idea how strong it is (never having used it), but the Loctite plastic
glue here :

http://www.loctiteproducts.com/p/sg_...ing-System.htm

claims to stick to polythene and teflon (== PTFE as far as I know)
