There’s the old standby: Gorilla Glue.  And there’s Elmer’s Ultimate Glue. And Bolder Bond. Now there’s another polyurethane glue on the market: Rhino Ultra Glue made by the folks at Liquid Nails.

Rhino Ultra Glue shares some of the same characteristics as other polyurethane glues: it’ll bond just about anything. But there is one important difference. This stuff sets up fast. After 40 minutes, you can “plane it, sand it, and stain it” as their bottle says. But get this — If you dampen the surface of the material to be bonded first, Rhino Ultra Glue sets up in half that time. That means that you only need to clamp it for 20 minutes.

There’s another difference. It’s higher-viscosity (thicker) formulation means it won’t run as easily as some other polyurethane glues. That’s real handy on complicated glue-ups where traditional glues run away from your joints before you can get things clamped together.

But what I like most about this product is the bottle. That’s right. The bottle has a flat side so you can store it on it’s side. That means that the glue will last longer because air can’t get to it. When the folks from Liquid Nails showed us this, we all said, “It’s about time.”

And there’s the long nozzle that helps get the glue where you need it. You can read all about the unique bottle features here.

Have you heard of the new, low-foam polyurethane glue called Bolder Bond (left photo)?

It works just like any other poly glue — it’s waterproof and bonds different materials together. But you can see the difference between Bolder Bond and a traditional polyurethane glue in the photo at right (click to enlarge). Bolder Bond has very little foam squeezeout (as shown in the upper glue joint). In the lower joint, you can see the high foaming action of typical polyurethane glue. Reducing the amount of foam makes cleanup less of a hassle.

Since Bolder Bond is new, there aren’t many places to find it right now. But the Woodsmith Store in Des Moines, Iowa carries it. Give them a call at 800-444-7527.

I received an email this morning asking a very basic, open-ended question: “What is the best adhesive to bond hardboard to plywood?” My quick answer was to use a yellow woodworkers glue. I also mentioned polyurethane glue as a good option for bonding just about anything. Read the rest of this article »
