Wood & Finishing Oils

A finishing oil soaks into wood rather than sitting on top of it, so the grain stays visible and the surface stays repairable. RMP Finishes has been making wood oil for over 30 years, with pure tung oil and pre-thinned tung blends, plus hemp oil, a ready-to-use cutting board oil, and a weather-resistant outdoor blend.

All wood oils are natural, free of synthetic additives, and safe for food contact once cured. Pick by project below, or compare the full range further down the page.

Tung oil is one of the most trusted natural finishes for wood, and for good reason. It’s made from pressed tung tree seeds and has been used for centuries to seal, strengthen, and protect surfaces. At RMP Finishes, our tung oil blends are 100% natural, all made without synthetic additives, and are safe for food-contact use once cured.

These oils are made to enhance grain, defend against water damage, and give your wood a rich, lasting finish, which makes them perfect for cutting boards, farmhouse tables, and backyard benches.

Explore Our Wood & Finishing Oils

All wood oils in our collection are tailored for a different type of project. Here’s a quick look at what’s available:

• Pure Tung Oil – A 100% natural, original-source Chinese tung oil with no additives. This oil cures to a tough, food-safe finish ideal for end-grain cutting boards, butcher blocks, and indoor wood features.
• Half & Half – A balanced mix of pure tung oil and citrus solvent or pine solvent. It spreads more easily and soaks in faster, great for first-timers or dense woods.
• Dark Tung Oil – Provides the same durable protection as our pure formula, but with added depth of a light chocolate color. Expect a warmer tone that brings out grain patterns beautifully.
• Dark Half – Combines Dark Tung Oil with citrus solvent or pine solvent for a warmer tone and smoother application. Adds depth to the wood grain and creates an aged, lived-in look right away.
• Outdoor Defense Oil – Formulated to handle changing weather. Great for raised garden beds, wood patio furniture, siding, or any outdoor project exposed to sun, rain, and snow.
• Cutting Board Oil – A food-safe blend made for kitchen use, specially formulated to condition and protect cutting boards, utensils, and charcuterie boards.
• Hemp Oil – A plant-based, solvent-free oil finish that protects raw wood, restores antique finishes, and absorbs easily into porous surfaces with a natural, matte look and no thinning required.

How Wood Oil Works

Specialist wood oil like tung oil doesn’t sit on the surface like a varnish. Instead, it seeps into the wood’s fibers and cures from within, creating a flexible barrier that repels moisture while letting the wood breathe.

This type of wood oil is very resistant to cracking or peeling over time. It also leaves a clean, matte finish that feels just as good as it looks. Once cured, it’s non-toxic and safe for use on items that come into contact with food.
