PVA or similar with longest time before it sets?

[fobos8]

Hi all

Been doing a few face frame to cabinet assemblies recently and realise that the Gripfill PVA I'm using goes hard far too quick before I can get all the clamps on.

Which similar type of glue should I be using to give myself the most time to get everything positioned and clamped?

Titebond II or
Titebond III or

something else??

Cheers, Andrew

I used Titebond Extend when laminating a worktop, with success. The specs for it show that you get 5 - 10 mins more than a "standard" PVA for spreading the glue and getting the clamps tightened. Beware that on large areas it has significant grab, so once mated, parts need a hefty thump if you need to slide them into place. It isn't a waterproof PVA either.

Good luck

Cascamite / Extramite / Polymite, whatever they call it now :shock:

All though you have to mix yourself, it's greater open time is good for larger items, like table tops, I wish I'd done this with my recent coffee table top, I used Titebond 2, and it was going off whilst trying to adjust the clamps :evil:

Have a look at this

But there is also Titebond II extend that is the 'waterproof' version of T II. Norm used Titebond II for most of his ouside projects and they were still holding up well years later.

Ooooh yes. That's useful to know. Thankyou. I think that's appeared since I bought the "Orginal" Extend. Looks like Axminster don't have it yet, but Rutlands do.

I think Titebond III also has a longer open time but the standard Titebond glues (I and II) only allow you ten minutes or so, like many PVAs.

Personally, I wouldn't use "cascamite" for mortise and tenon joints as it tends to be quite 'brittle' once dry. Although, with it's long open time, it is ideal for larger assemblies; edge-jointing, laminating and veneering.

Agree with Olly here, TBIII has a slightly longer 'open' time but it ain't much and in the warmer weather [-o< you're still going to have much the same sort of issue.
Cascamite, and variations thereof, are the alternatives but present additional problems such as mixing too much and the glue going 'off' in the tin - Rob
