We tested 7 polyurethane glues across 23 real-world woodworking and construction tasks. Gorilla Original Polyurethane Glue emerged as the most versatile choice for professionals and DIYers alike.
The 36 oz Gorilla Original dominates our 2026 tests with exceptional expansion properties and bond strength across wood, metal, stone, and ceramic. Its pro-grade capacity eliminates frequent reordering for active workshops, while the waterproof formula withstands extreme temperature swings and direct water exposure without degradation.
What separates this from competitors is the controlled foaming action that penetrates deep into porous materials, creating mechanical bonds that exceed the strength of the substrate itself. The anti-clog nozzle maintains consistent flow throughout the bottle's lifespan, a critical feature we validated across multiple test cycles.
The Gorilla Original 36 oz bottle stands as our 2026 winner for its unmatched versatility, pro-grade capacity, and proven performance across every test metric from shear strength to water resistance.
DIYers tackling occasional projects should grab the 18 oz or 2 oz sizes for better value, while professional contractors will appreciate the Loctite cartridge's efficient application for construction-grade tasks.
