We have used for years Titebond 3 wood glue when assembling bee frames and boxes. Titebond 3 is waterproof and is an excellent choice for beekeepers because of its non-toxic formula, incredibly strong adhesion, and easy cleanup formula. When assembling woodenware, it should be used on every joint where wood touches wood, both in boxes and in frames.
We prefer Titebond 3 over Titebond 2 for beekeeping equipment because the Titebond 3 formula has a longer window to work with before setting and is stronger than Titebond 2 when set.
From the Manufacturer:
Titebond III Ultimate Wood Glue is the first one-part, water-cleanup wood glue ever offered that is proven waterproof. The waterproof formula passes the ANSI/HPVA Type I water-resistance specification and offers superior bond strength, longer open assembly time and lower application temperature. Titebond III is non-toxic, solvent-free and cleans up with water - safer to use than traditional waterproof wood glues. It provides strong initial tack, sands easily without softening and is for indirect food contact (cutting boards). The ultimate in wood glues - ideal for both interior and exterior applications.
