Easy to Use - Tung oil is a natural oil recognized by craftsmen to offer the ultimate hand-rubbed finish for all fine woods; just wipe on and allow the oil to cure at room temperature

Permeates - Unlike other finishes that form a film on the wood’s surface, tung oil penetrates deep into the wood fibers, cures to a flexible non-oily solid, and becomes part of the wood itself

Protects - Resistant to moisture, alcohol, oil, and everyday wear for lasting beauty and protection; lasts many times longer than mineral oil and wax based products

Multi Use - Amazing results on almost any surface that will allow the oil to penetrate - new unfinished wood, weathered wood, stripped wood, concrete floors and countertops, even brick, stone, and cast iron

Great for Food Contact Surfaces - Since tung oil is considered non-toxic when dry, it is great for cutting boards, butcher blocks, countertops, wooden bowls, wooden utensils, and more

100% Pure Tung Oil- Hope's Tung Oil is the “best of the best” pure Tung oil grades. We only use premium oil, pressed from the best Tung nut crops from growers around the world.
