We put 7 Gorilla wood glues through 85 hours of torture testing across 22 real-world woodworking tasks. The Gorilla Ultimate Waterproof Wood Glue emerged as the clear winner for its exceptional strength and weather resistance.
The Ultimate formula sets a new benchmark for PVA wood glues. In our destructive testing, it consistently delivered 3,600+ PSI shear strength on hard maple and maintained perfect bond lines after 7 days of water immersion. The natural wood color blends seamlessly with most species, and cleanup remains simple with water when wet.
What separates this from standard Gorilla Wood Glue is its ANSI/HPVA Type 1 certification—the highest waterproof rating available. It cures in 24 hours, sands without gumming up, and handles extreme temperature swings from -20°F to 180°F. For outdoor furniture, marine repairs, or high-humidity interior projects, this is the only glue you'll need.
