So I’m in the middle of a big glue up at the moment – about 50 jointed pallet member surfaces to be glued for a bench top. I was in the hardware shop and on the shelf, there’s the standard builders PVA and Gorilla glue sat next to each other…

now the timber for this 6’ x 4’ x 4’’ top only cost me £4 (about $7) and the glue is costing me £15…

So I’m thinking what I think most woodworkers have thought at least once – why not just use standard PVA for glue ups where fatigue and strength aren’t a huge issue?

What does `yellow` glue have that PVA doesn’t?

(I’m sure this has been asked before but I couldn’t find it searchin the site)

thanks

AFAIK, yellow and white glue are both PVA, although have different tack and set time depending on additives Gorilla glue on the other hand is a completely different animal (pun intended).

Cheers,
Brad

PS: I just use whatever is cheapest as long as water resistance isn’t needed (then I turn to titebond II/III or epoxy).

For a bench top I would use Gorilla Glue. I sure it would take a good pounding. I have been using it for Gorilla products years and years
and love the stuff. Of course I won a Gorilla Glue contest here back in the day. Won a whole box of Gorilla glues, tape and samples back in 2008.

Good old Elmer’s school glue works perfectly fine for anything that doesn’t need the extra water resistance of the newer PVA wood glues. I’ve used it in the past while building a nearly $20,000 dining table and had perfect confidence in its ability to hold up.

Now I’m using Titebond III. We’re doing a wide range of projects and some of them do need the water resistance plus I like the initial tack of the Titebond and it has the same open time. Elmer’s glue is runny and parts are more likely to slide when clamping them. Stocking two types of glue is a hassle so Titebond III is the choice. It’s purchased by the gallon.

Gorilla Glue is a brand name. They make several different products. Which flavor of Gorilla Glue are you recommending???

It’s really a crapshoot with glue if you don’t need water resistance. I use tb2 & 3.

I’ve used all kinds of glue from white Elmers, yellow Elmers, all 3 Titebonds, generic yellow glue; outside water resistance and tack time they are all more than strong enough for wood. The yellow Elmers has the fastest tack time, nice when you aren’t trying to glue 50 things at once.

I’m struggling with the question: someone else mentioned it, I think yellow glue is PVA. Do I misunderstand? That said, it seems like ₤15 is an awful lot of glue, or at least an awful lot of money for glue.
