What is teak oil made of?
Teak oil gets its name because it’s perfect for use on teak wood, such as teak outdoor furniture. Teak oil is typically made from linseed oil, mineral spirits (petroleum naphtha), pure tung oil, and varnish. Petroleum naphtha acts as an oil thinner to help the mixture penetrate wood easily. Many teak oil formulations also contain UV filters to protect the wood from harmful rays and slow down the natural greying process.
Teak oil is used to preserve outdoor wooden furniture and wooden elements on boats. While it works on both softwood and hardwood, hardwoods are preferred because teak oil is thin and softwoods absorb more, making it more expensive to use.

Teak Oil Advantages and Disadvantages
Advantages:
- Absorbs and dries quickly (2–8 hours).
- Contains UV filters to prevent fading.
- Prevents cracking, peeling, and chipping by protecting wood from the inside.
- Penetrates dense woods like mahogany and rosewood.
- Can be customized for gloss or matte finishes.
Disadvantages:
- Creates a strong barrier, which can prevent bonding with other finishes.
- May change wood color over time.
- Some teak oils offer limited longevity.
Is Ronseal furniture oil a superior alternative to teak oil?
Yes, Ronseal Hardwood Furniture Oil is a great alternative to teak oil. It creates a waterproofing barrier and enhances the natural beauty of outdoor furniture. It also feeds and nurtures wood by replenishing essential oils, making it a superior option to traditional teak oil.
Danish Oil as an Alternative
Danish oil is made from oil mixed with varnish and thinner. It usually combines boiled linseed oil and tung oil, working together to enhance the wood’s natural appearance while providing some protection.
How to apply Danish oil:
- Sand the wood smooth (220 grit).
- Wipe off sanding dust.
- Apply the first coat with a brush for even coverage.
- Watch for areas that dry quickly and apply more as needed.
- Let it soak in for 20 minutes, then wipe off excess.
- Buff in a circular motion for a silky, natural finish.
Linseed Oil as an Alternative
Linseed oil is a plant-based alternative to teak oil. It provides some weather resistance, but it darkens the wood and does not last as long as teak oil.
How to apply linseed oil:
- Sand the raw wood with 120 grit sandpaper and remove dust.
- Mix the first coat with a mild solvent like citrus solvent for better penetration.
- Apply with a brush, roller, or cloth.
- Wipe off excess 10–15 minutes after application.
- Repeat 2–3 coats at 12–24-hour intervals for best results.
Cheaper Alternatives to Teak Oil
Olive oil can be used as a budget-friendly alternative to teak oil. Although it doesn’t last as long, it keeps wood moisturized and looking smooth.
Application tips:
- Apply a thin layer of olive oil and wipe away excess with a soft cloth.
- Repeat regularly for ongoing moisture and sheen.
Sealers are another option. They don’t “feed” wood but create a protective barrier that repels pollutants and moisture.
- Reapply sealers every year for best results.
Other Options: Varnish and Sealers
Varnish:
- Durable and water-repellent.
- UV-blocking or UV-reflecting varnishes protect wood outdoors.
- Apply to well-sanded wood on dry, sunny days for best adhesion.
- Sand and polish as needed; varnish can last 3–5 years.
Sealers:
- Create a glossy, smooth finish that repels water and dirt.
- Prevent loss of natural wood oils.
- Must be reapplied every 2–3 months for continued protection.
- Apply only to oil-free wood surfaces cleaned with solvents like acetone.
Tung Oil as an Alternative
Tung oil is another plant-based substitute for teak oil. It boasts a finish that creates a glossy, waterproof surface and enhances the wood’s natural beauty.
