Bolder Bond Featured in Woodcraft Video

When duct tape sleeps, it dreams of being Bolder Wrap. That’s because Bolder Wrap isn’t just sticky; it’s structural. So it can actually make the kind of repairs that duct tape has tried and failed for years: broken handles, cracked pipes, and even fence posts.
In fact, its not really even fair to call Bolder Wrap “tape”. It’s actually a structural composite fabric, developed by Comptek, which has long been in the business of reinforcing communications towers and oil and gas pipelines. So fixing shovels is a walk in the park for these folks.
At the heart of Bolder Wrap is a fiberglass fabric. This fabric is saturated with a proprietary polyurethane adhesive. Together they create a super-rigid, super-strong repair for just about any surface you can imagine.
Q: I’d heard that polyurethane glue foams up as it cures, but I was surprised by just how much. Do you have any suggestions for controlling the foam? Also, what’s the best way to clean it up?

A: If you’re used to using yellow glue, polyurethane takes some getting used to. The squeeze-out from yellow glue or polyurethane glue makes a mess. But with standard polyurethane, the mess grows because the glue expands as it foams. To keep this mess under control, start by using less polyurethane glue than you would with yellow glue. Another possible option is a new “low-foam” polyurethane glue called Bolder Bond (BolderBond.com). To test it, I glued up blocks without clamps using equal amounts of low foam and a “standard” polyurethane glue. The difference in foaming was significant. With clamps, of course, neither type of polyurethane will spread the joint apart. But using “low-foam” glue should result in less squeezeout. To clean up either type of polyurethane glue, wait until the glue dries, then scrape it off.
Woodcraft Magazine: Low Foam, Higher Strength Poly Glue, Bolder Bond Polyurethane Glue
When polyurethane glues first appeared on the woodworking scene a decade ago, they were touted as the “ultimate” adhesive solution. Now that the foam’s had time to fully harden, these one-part, waterproof adhesives have proven their usefulness for some projects, especially for outdoor use and for joining metals, plastics, or oily woods. I appreciate the fact that dried poly glue is easy to sand and doesn’t chip, chisel or plane blades. But polys aren’t perfect. I find the foam more of a nuisance than gap filler and some don’t seem as strong as good old yellow glue or epoxy.
The benefits of Bolder Bond are subtle, but significant enough to warrant a fresh look. For one, this glue isn’t new. This industrial-grade adhesive has been used to repair and reinforce cellular phone towers and high pressure gas pipes for 15 years. The low-foam blend designed to make less mess in the field also makes for a cleaner shop experience. Most importantly, third-party testing has found that Bolder Bond has a 20-25% higher mechanical property (basically, “more grip”) than its competition.
By giving more of what I really want from a poly glue and less of what I don’t, this bottle has earned a spot on my shelf.
