Q:
I need to glue up panels in an unheated shop. Are there glues that work on hardwood—in this case, cherry—in the 40° to 45ºF range?

A:
I contacted Franklin International and Gorilla Glue to see how cold you can go and still glue wood successfully. Joe Goodwin at Franklin had the minimum temperature for Titebond III memorized: “47°!” He also said Titebond II needs to be used above 55º F, and Titebond Original, Carpenters glue, liquid hide glue, and polyurethane must be above 50º. Below this, the glue dries white and powdery instead of transparent, and has virtually no bond strength.
Cyanoacrylate (“Super Glue”) also is not suitable for applications in the 40° to 45º range. Some epoxies work, but take much longer than normal to cure. Gorilla Glue polyurethane can handle 40°, but the cure time also is slower.
The bottom line: Use Gorilla Glue down to 40°F and Titebond III down to 47°F, but the best solution is to heat your shop a bit. Everything will be easier then.
