The minimum shelf life of Titebond III is stated as one year, when stored appropriately at room temperature. Titebond III is expected to last beyond its stated shelf life. If thickened, shake vigorously by firmly tapping bottle on a hard surface until product is restored to original form.
The bottle is almost full and it is as smooth and liquid as the day I bought it. Is age alone a reason to toss it?
Thanks,
Charles
