I've never used Gorilla Glue. I have a couple of questions.
1. Is Gorilla Glue gap filling?
2. Can you use Gorilla Glue for biscuit joints?
3. I'd also be interested in anyone's comments and/or warnings.

| I've never used Gorilla Glue. I have a couple of questions.

Yes, when used as directed it foams and expands.

I've never used it for that - but would suppose so.

Cleans up nicely with paper towel and acetone.

Leaving a bunch of air holes. It is not gap filling in the sense I
suspect OP means.
I would say the answer to the question is "no".
Certainly? However, it's only real advantage is the waterproof result.
Makes a hell of a mess and takes several hours clamping time to cure.
Will not work as a "slide 'n glide" joint w/o clamping for things like
corner blocks, etc., like white or yellow glues can.
Harder than a rock once dry so cleanup is a bitch. Having to use a
solvent is a pita (as compared to water).
Has no real advantage and many disadvantages other than for the
waterproof nature or for some oily woods such as teak, etc., which don't
work well w/ other types.
Three times the cost roughly of yellow aliphatic, roughly twice the cost
of Type III waterproof. Type II is in between Type I and III for cost.
Yes absolutely it is. BUT is does not add any strength to the joint at that
point. This type glue foams and expands and will fill voids.
Probably not a good idea as biscuits need to expand as does the wood that
you put the into. Gorilla glue does not have water in it but does cure
faster if water is added. The more water you use the more foaming you will
see and perhaps you will see a bigger mess.
Keep acetone handy to immediately remove the glue from you hands. Once
cured it has to wear off.
Ummmm.... no, they don't "need to expand". Biscuits are principally for
alignment, not structural strength, and as long as you get a snug fit in the
slot, Gorilla Glue is just fine. In fact, you can make a case for Gorilla Glue
being *superior* to PVA glues for biscuits, precisely because it does *not*
make them expand -- just read the occasional thread here about biscuit-shaped
*depressions* along a glue line (caused by sanding too soon after glue-up with
a water-based glue) to understand why.
Unless you live in an _extremely_ arid climate, there's enough moisture
present in the wood already for Gorilla Glue to cure, without need of adding
Paint thinner (mineral spirits) works, too, and it's a lot cheaper than

That is the popular view but from the books that factually address biscuits
alone they are indeed structural especially when used on 45 degree miters
and on end grain applications such as when attaching shelves with biscuits
to cabinet walls. They do indeed need to expand to make a solid and tight
It will fill the gap but won't provide strength through the gap - if
that makes any sense to you.
It could and would hold quite well, I imagine. However, proper
application requires that you WET one side of the glue joint. What's
that going to do to your biscuit. I guess the answer to this one is MAYBE
Cost vs benefit vs ease of use - Don't think I'd be using it to glue up
panels. Any of the Tite-Bonds (or similar) would serve you as well and
Haven't tested this out yet but supposedly Gorilla Glue has a 180 day
shelf life after opening. I have had one open longer than that and it
still appears usable.
Can anyone comment on that?
I've had the poly glues from both Franklin (Titebond folks) and Probond
(Elmer's?) go hard in the bottle, and get tossed, before I used more than a
The only reason I buy this type at all is to glue the odd exotic...
with maybe 8 or 9 variations of adhesives on the shop shelf, but Original
Titebond is the one I seem to reach for most.
I originally purchased Gorilla glue for use with melamine cabinets.
Quickly became disenchanted with its exhorbitant cost and laughingly
short shelf life.
Have since shifted to Roo Glue from Woodcraft. Excellent bonding
properties, long shelf life, and is used exactly as you would any
yellow glue. And did I mention that it's cheap?
This has been my experience too.
It helps some to store the opened bottle upside down
but it still goes bad before I get around to using it all.
I wish they would package it in a collapsible package,
like a toothpaste tube, to keep the air/humidity out.
Andy, what do you use when you want a glue with a slower setup time? Every
time David Marks is doing a complicated glueup he says use something with a
longer working time and it sure looks like a bottle of Gorilla glue he's
