Today I was putting some 1/2″ steel pegs into a number of oak boards. I drilled the boards so that the pegs were snug and before pushing them in put a small amount of Gorilla Glue in the holes. 20 minutes later the glue began to foam around the pegs and after repeatedly wiping it away I finally abandoned the experiment and pulled the pegs out. Three hours later the holes were still filling up with foamy glue – even after I wiped them out carefully with Q tips.
The stuff is worse than expanding foam. I guess tomorrow I’m drilling, sanding and staining the boards again. Wretched stuff. I’m sworn off for life.

You can put that experience into your bag of application techniques.

No, the last few bottle holders for a wine cellar I have been working on sporadically for two years.
I wouldn't mind so much if the container had some caution like "This glue expands to ruin your project", as opposed to a bunch of soothing stuff about how it is the only glue to stuck together anything you can think of.
I'm sure that there must be some good reasons to use foaming polyurethane glues.
Perhaps someone will post one here.

It is not harmed by freezing temps and can be used down to 40*F... this makes it handy stuff in Minnesota. Can also be used for structural joints. Typical PVA glues will creep over time, if loaded.
I used it to glue some rare earth magnets to some nice beach rocks. Made awesome refrigerator magnets. Also used it to reattach a couple of shovel heads to their wooden handles. Worked great in both situations.
I know a guy who made a built up beam of 2x12 PT which he steamed first and bent around a form.
the glue works wet. Supposed to wet it I think.
IIRC Gorrilla Glue was what we used to fasten a small chip back on to a precast concrete window sill we bush hammered. I thought no way it would survive but it is still there after 5 years and lots of freeze thaw cycles.
Yeah, it's a reasonably good masonry glue.

A few years ago I made a ladder for an upper set of cabinets in a bedroom. Part of the hardware involved a rail. Because the rail was made from EMT and I did not want to make one from pipe or rigid electrical conduit I placed a piece of closet pole inside and filed the space with Polyurethane glue. The space was filled very well and the rail was remarkably stiffer and light too.

The foaming is a natural part of the curing process. I like it, because once the glue is cured, its easy to carve off the excess foam. And I've found it doesn't sink into the wood, and affect a finish.
You shouldn't have tried wiping it as it dried. I let it dry before I worry about any squeeze out. What did you try wiping it with? If it was water, that would just increase any foaming action. IIRC, mineral spirits is what's recommended for clean up, but I find that doesn't work all that well, especially when you get the glue on your clothes, or skin, which I have a tendency to do <G> It really has to be cleaned up almost immediately to have a chance.
I like polyurethane glues for some applications. It'll bond just about anything, like an epoxy, but it's cheaper, and it doesn't have to be mixed.
that much foaming means too much glue...

Once things went bad, I removed the pegs and carefully cleaned out the holes with Q Tips. Twenty minutes later the 1/2" dia. by 1" deep holes were overflowing! How much is enough?
did you clean up with denatured alcohol???
just a drop or two....
when ya think you haven't used enuff...
it already was too much...

It takes some getting used to. But it really is good stuff for certain applications. I keep a bottle in the freezer.

It's good glue, but the foaming nature can take you buy surprise.
What shep said.
Don't wipe it. Let it do its thing, then come back the next day with a paint scraper. No problemo.

The pegs were already spray painted and the oak stained, so once it came out of the hole I was done. The annoying thing about it is I really didn't need the glue - the pegs fit tightly and are supported by the oak. I just thought I'd put a dab of something on in case things shrunk. Grabbed a bottle off a shelf in the guys shop and...
That's a good application for a small amount of Marine Grade Goop.

Ditto on the denatured alcohol, and a tooth brush. There is a definite learning curve , the attachment was done with gorilla glue poly it's a muntin on a window . Once you learn the stuff, and how to apply. As IMERC said denatured alcohol and a nice fine toothbrush , wait until it reaches it peak foaming ,but hasn't harden up , gently scrub it with the alcohol. it has a tendency to retard the foaming also. Not to much cause it will compromise the the integrity of the bond. I'll point it out but it pretty obvious , if your staining the gorilla polyurethane is not for this application.
If I'm ever concerned about the foaming as it dries while working with a delicate (stained) surface:
Stain and finish wood as needed. Cover area as needed with a lighter duty painters tape. Drill holes as needed with tape already in place. This way, you have your holes, with no exposed wood. Use gorilla glue sparingly.
After it has completely cured, cut away any excess glue. Remove your tape.
In your case, you could tape your spindles to protect their finish, too.

Most glues have their place. I think Fine Woodworking did a comparative test on glues a while ago. If I recall PVA glue was somewhere close to the top in terms of strength (when bonding wood to wood). And polyurethane glues were at the lower end of the spectrum in the same application. In your instance gluing steel to wood I would think that epoxy would be the best choice in terms of working time, application and cleanup not to mention superior strength compared to Gorilla glue. I'm with you on the stuff, Can't think of a reason to use it where another cleaner and stronger glue would get the job done.
It's great for gluing up panels that can sanded: wooden countertops and the like. it's a beech in anything with a corner. works nicely with bent laminations, or most any laminations.http://www.tvwsolar.com

The application which you used it for is not ideal. In most cases you do get the excessive foaming but alot of the time the curing action will actually push out a plug or in your case steel peg. An epoxy would have been better suited. Try West Systems epoxy, great stuff and alot of extra information and tips are available on there web site. Good luck.
