Titebond makes three different wood glues that all sit on the same shelf, Original, II, and III, and the naming alone leaves most buyers guessing whether the higher number means genuinely stronger or just more expensive. Add in Elmer's, Gorilla, and Flex Glue as competitors, and the choice at the hardware store gets more complicated than it should be for a product that is, on paper, just PVA glue in a bottle.
So a hands-on tester bought eight wood glue products, including all three Titebond formulas, and ran them through dry tensile strength, shear strength, and a water-soak durability test. The results genuinely complicate the simple "higher number is better" assumption about the Titebond lineup.
Here is what actually happened.
What the testing showed
Every result below comes from Project Farm's independent bench testing. You can watch the full breakdown on the complete wood glue comparison, which tests all three Titebond formulas directly against Elmer's, Gorilla, and other competitors.
The eight glues went through a dry tensile strength test, a shear strength test, and a water-soak test measuring how much strength each glue retained after prolonged water exposure. No single brand was declared the overall winner across every test; different products led different categories.
Titebond III did not automatically beat Titebond Original or II on every metric
Titebond III, at 6 dollars and 99 cents, the priciest of the three Titebond formulas in this lineup, performed better than Titebond Original or Titebond II specifically in the dry tensile test. But it did not win the shear strength test outright; that category went to Elmer's Max, with Titebond III finishing a close second per the tester's recap. The naming convention (III being the newest formula) does not mean automatic superiority across every measured property.
Elmer's Max actually won the shear strength category
Elmer's Max Wood Glue, at 6 dollars and 78 cents, essentially the same price as Titebond III, came out on top specifically in the shear strength test. It also held up in the water-soak test, with its lowest single sample still delivering over 1,000 pounds of tensile strength, a result the tester grouped alongside Titebond III as one of the strongest performers under water exposure.
Titebond II clearly outperformed Titebond Original
Within the Titebond lineup itself, Titebond II, at 5 dollars and 47 cents, showed a clear, direct improvement over Titebond Original, at 3 dollars and 97 cents. The tester's own words: it "did quite a bit better than Titebond Original for shear load and definitely seems stronger for shear than Titebond Original," with a shear-strength recap figure of 1,688 pounds. Titebond Original, by comparison, was noted as failing in some areas during testing.
Elmer's Original Carpenter's Glue punched above its price using an outlier-removal method
Elmer's Original Carpenter's Wood Glue, at 4 dollars and 87 cents, notably cheaper than any Titebond formula, actually came out first in the dry tensile test once the lowest-performing sample from each product was removed from the results, a data-outlier method the tester applied. Under that specific method, it beat Titebond III, Titebond II, and Elmer's Max.
The most expensive product was not the strongest
Flex Glue, at 12 dollars and 99 cents, the most expensive product in the entire test, delivered fairly consistent results across all three tests but posted the lowest absolute numbers overall, and it showed cohesive failure (sticking well to the wood but failing within the glue itself) in some samples.
How to read this for your own purchase
The Titebond lineup itself is genuinely nuanced based on this data: Titebond II is a clear, meaningful upgrade over Original for shear strength, but Titebond III does not automatically dominate every test the way its position as the newest, priciest formula might suggest. Elmer's Max, at a comparable price to Titebond III, actually beat it on shear strength specifically.
If your project needs strong shear resistance, the tested data supports Elmer's Max or Titebond III as close competitors, both ahead of Titebond Original and II on that specific measure, with Elmer's Max edging out Titebond III in this particular test.
If your project will face water exposure, both Titebond III and Elmer's Max held up strongly in the water-soak test, making either a reasonable choice for outdoor or moisture-prone furniture and repairs.
If you are choosing purely within the Titebond line and want the best value, Titebond II represents a real, tested step up from Titebond Original at a modest price increase, without necessarily needing to pay for Titebond III's premium.
A few universal rules the results support:
- A higher Roman numeral or newer formula name does not guarantee better performance on every metric. Titebond III's strength was specific to the dry tensile test, not a clean sweep.
- Craft or all-purpose glue is a real, if imperfect, substitute for dedicated wood glue in a pinch, based on the tester's comparison point, but it is not designed or optimized for wood-specific bonding the way the dedicated products are.
- Price does not guarantee strength. The most expensive product in this test, Flex Glue, posted the lowest absolute numbers across all three tests.
