How does tung oil work on wood?
Tung oil absorbs around twelve percent of oxygen when applied to wood to create a waterproof surface layer. As it reacts to the oxygen in the atmosphere, it continues to polymerize, creating a thin and water-resistant layer or film over the wood surface. Tung oil is derived from the berry seeds of a tree named Vernicia fordii.
What is polymerized tung oil?
Many woodworkers who use tung oil often complain about the length of time it takes to cure this product after application. Thus, to reduce the curing time, vendors have come up with a formulation called polymerized tung oil. This product has undergone a cooking process to hasten the drying process.
