Think “outdoor adhesive” and the word “waterproof” may come to mind. But joints made with these adhesives need to survive more than mere rain. Climate extremes in parts of the U.S. go from subzero to 100+ degrees—challenging for any adhesive. To discover which adhesives stand up to Mother Nature, we tested four types of products—a type-3 waterproof glue, a type-2 water-resistant glue, epoxy, and polyurethane—on dozens of half-lap joints in cedar. So which of these adhesives worked the best? We think you’ll find our results quite interesting.
