Oak and Teak glue, the all wood glue, is a two part epoxy resin made largely from the resins of wood itself. That is why it can dissolve the natural oils of oily hardwoods, and why it bonds all oily hardwoods such as Teak, Cocobolo and Ebony. Oak and Teak Epoxy Wood Glue will of course bond all non oily hardwoods. Oak and Teak Epoxy Wood Glue is unaffected by the natural acids common to many woods, which is why it bonds Oak so readily. It will fill gaps and delivers astonishing bond strength and durability and is completely waterproof and weatherproof once set.
