It is Polyeuthane (PU) glue.


Be aware you want gloves on (it stains hands VERY well) and water activates it so working time in a damp workshop is not too high...

The foaming property is a feature of thixotropic glues, which can come in both PU and PVA formulations.

I've only experience of PU thixotropic glues, both 30 and 5 minute set types (Everbuild Lumberjack). Titebond make a thixotropic PVA which might be worth a look.

You should wipe/dampen surfaces before applying to increase penetration and speed hardening.

Not that it needs any speeding up mind - I've been using 5 minute set stuff, and it really does: Everything has to be exact, dowelled and test assembled first, then I have 5 minutes to glue to all edges, assemble and whack tight with a mallet. Clamping can extend into the 30 minute curing/hardening window, but not by much.

Cup of tea later, box solid, next job.

You might want to start with the 30-minute set stuff, the 5 minute stuff is like using cyanoacrylic superglue, there's little margin for error, it has a grab time of seconds.

Soudal is the best PU by far. Stuff like timbond and everbuild seem to more effected by cold weather and the stuff wont flow or go off. Soudal cleans off beautifully with the back of a chisel. Best Tip, Always buy in tubes never bottle, Just get yourself in a right old mess. Bottle are for first fix chippies house bashing.

And use sash clamps with thick cls timbers across both sides of box as it will push your joints apart.

Ditto joint shear - the expanding glue can cause the joint to offset, often perpendicular to clamping

SouthwestCNC: Where do you get Soudal PU in tubes? Only ever seen it in bottles. If I'm only using it occasionally, tubes do keep fresher once opened. A half full bottle has a lot of air to cure with.

I agree with you on the everbond. I've been using some 3 year old tubes (12 month shelf life) and it doesn't flow as well as it did when fresh, but sticks just the same. They've been stored indoors mind - anything in a lockup over a long cold weekend is a different matter.

https://www.amazon.co.uk/Soudal-Purocol-Assembly-Adhesive-310-ml-Clear/dp/B007WFURZE/ref=sr_1_1?ie=UTF8&qid=1492015798&sr=8-1&keywords=soudal+purocol

You shouldn't pay as much as that tho ^

Or westward tool base is where I go.

putting the bottle or tube on a radiator helps it flow. the more yellow the pu the harder it is to clean off, the longer it takes to set and the set is softer I find. apart from being in a bottle another reason gorilla glue etc is not very good. soudal dries white and rock hard when bulging. In a tight joint its kinda clear.

DEFINATELY go for the tubes rather than bottles. You look at the bottles and they seem a much better deal but by the time you're half way down it has thickened enough to make it a pain to squeeze out of the bottle. The tubes go in a standard mastic gun.

I have to confess I've never had any problems with the everbuild brand  and must have used close on 100 tubes of the stuff. As above the excess cleans off easily with a sharp chisel.
If it's got wheels or tits it's gonna cost a fortune
