glues on oily woods such as teak, we found that all four products performed equally well on our teak edge grain. Your results, however, may vary depending on the oiliness of the wood. Experiment by gluing up a few scraps before you commit a large project to a particular glue.

We did find a difference in gluing aluminum and brass to wood. Here, the polyurethanes held fast, while Elmer's and Titebond II failed to bond to the metal.

•Price

The chart at right shows the cost per ounce of each of the glues. The cost will vary depending on the size of container you buy. The more you buy, the less you pay per ounce. And keep in mind that the high cost of the polyurethanes can be partially offset by the fact that you get more coverage per ounce.

Our recommendations

Elmer's Weather-Tite Wood Glue and Titebond II do a good job at a price that's hard to beat. They still deserve a spot on every woodworker's shelf. Choose Elmer's Weather-Tite Wood Glue when you want to prevent a messy squeeze-out, and use Titebond II for projects exposed to the rain.

But for many specific needs— waterproof joints, metal-to-wood joints, and creep resistance—the polyurethanes outperform the AR glues and prove much easier to use than the old two-part epoxies. The polyurethanes also make a good choice when you know you'll need extra open time to assemble a glue-up with a lot of parts, or you anticipate lots of sanding or scraping.

As they cure, polyurethane glues expand, forcing the glue into the wood fibers and helping to fill small gaps.

Although Gorilla Glue costs roughly 30% more than Excel, we didn't detect any significant performance differences once they had dried. That makes Excel a better buy per ounce in the bottle, but these glues are not entirely identical. Gorilla Glue is solvent-free and odorless, whereas Excel contains about 5% solvent by volume and imparts a slight odor. And, Gorilla expands more than Excel, and offers a shorter clamp time.
