FAQ
Frequently Asked Questions
No. Both are natural drying oils, but they come from different plants (tung tree vs. flax) and have different chemical properties, with tung oil generally being more water-resistant.
Yes, pure tung oil provides good water resistance and is suitable for outdoor wood, though it may require more frequent reapplication than some modern sealants.
Pure tung oil dries slowly, often taking 24-48 hours per coat to cure fully. Commercial 'tung oil finishes' may contain driers and dry faster.
The name comes from the Chinese word 't'ung' (桐) for the tree (Vernicia fordii), from whose nuts the oil is pressed.
