Wood is a beautiful and timeless material for outdoor furniture, decks, and structures. However, exposure to the elements can cause damage over time. Instead of using chemical-based treatments, why not learn how to treat wood for outdoor use naturally?
This guide will walk you through easy, eco-friendly methods to protect your wood while maintaining its natural beauty and extending its lifespan.
Why Treat Wood for Outdoor Use?
Outdoor wood is vulnerable to moisture, UV rays, mold, and insect damage. Without proper treatment, the wood can rot, warp, or crack, reducing its durability and appearance.
Natural treatments provide a healthier alternative to chemical-based wood preservatives, making them safer for you, your family, and the environment.
Preparing Wood for Natural Treatment
Before applying any natural treatment, proper preparation of the wood is essential. This helps ensure the treatment is absorbed effectively.
Clean the Wood
Dirt, grime, and mildew can prevent the treatment from penetrating the wood. Clean the surface using a natural solution of water and mild soap or vinegar. For tough stains, use a brush with soft bristles to scrub the wood gently. Avoid harsh chemical cleaners, as they can damage the wood and the environment.
Sand the Surface
Sanding the wood helps remove any rough spots or old coatings that might prevent proper absorption of natural oils or sealants. Use medium-grit sandpaper (80-120 grit) to smooth the surface, wiping away dust after sanding.
Best Natural Wood Treatments for Outdoor Use
There are several eco-friendly treatments available that can protect wood from weather damage while preserving its natural look. Here are some of the most effective natural options:
Linseed Oil
Linseed oil, derived from flax seeds, is one of the most popular natural wood treatments. It penetrates deep into the wood, nourishing and protecting it from moisture. It’s best used on bare or sanded wood.
- How to Apply: Use a clean cloth to apply a generous layer of linseed oil to the wood surface. Let it sit for 20-30 minutes, then wipe off any excess. Allow the wood to dry for 24 hours before applying a second coat if needed.
Tung Oil
Tung oil is another excellent option for treating outdoor wood naturally. It provides a durable, water-resistant finish while enhancing the wood’s natural grain.
- How to Apply: Similar to linseed oil, tung oil can be applied using a cloth. Make sure to apply thin, even coats and allow adequate drying time between each layer (around 24 hours).
Beeswax
Beeswax creates a water-resistant barrier that can protect wood from moisture and UV damage. It also gives the wood a smooth, polished finish.
- How to Apply: Melt the beeswax and combine it with a small amount of oil (such as olive or coconut oil). Rub the mixture into the wood using a soft cloth, and buff it to a shine.
Coconut Oil
Coconut oil is a readily available and natural way to protect wood from moisture. While it may not be as durable as tung or linseed oil, it’s a simple and effective solution for smaller projects.
- How to Apply: Warm a small amount of coconut oil and apply it to the wood using a soft cloth. Let the oil soak in for several hours before wiping off any excess.
Vinegar and Olive Oil
A homemade mix of vinegar and olive oil can be a simple natural treatment for outdoor wood. Vinegar helps clean and kill mold, while olive oil conditions and protects the wood.
- How to Apply: Mix equal parts vinegar and olive oil, and apply the solution using a cloth. Rub it into the wood and let it dry completely before use.
Benefits of Treating Wood Naturally
Choosing to treat wood naturally offers several advantages over chemical treatments:
Eco-Friendly
Natural treatments are free from harmful chemicals that can leach into the environment, making them an eco-friendly choice. They are biodegradable and won’t harm surrounding plants, animals, or soil.
Non-Toxic
Natural oils like linseed and tung oil are safe to handle and pose no health risks to you or your family. This is especially important if you have pets or children who might come into contact with treated wood.
Enhances Wood’s Natural Beauty
Natural treatments tend to preserve the wood’s natural appearance, enhancing its grain and texture instead of masking it. This gives your outdoor furniture or decking a beautiful, organic look.
Cost-Effective
Many natural treatments, like vinegar and coconut oil, are inexpensive and easily found in most households. You don’t need to invest in costly chemical treatments to protect your wood.
Long-Term Care for Naturally Treated Wood
While natural treatments are effective, they may require more frequent maintenance compared to synthetic sealants. Here’s how to care for your naturally treated wood over time:
Reapply Oil Regularly
Oils like linseed and tung oil need to be reapplied every few months, depending on exposure to weather conditions. Monitor your wood for signs of drying or cracking, and apply another coat when necessary.
Clean Periodically
Dirt and mildew can accumulate on outdoor wood, so it’s important to clean it regularly. Use a natural cleaner like water and vinegar to wipe down the wood every few weeks.

Cover During Harsh Weather
If possible, cover your outdoor wood furniture or decking during heavy rain or snow. While natural treatments are water-resistant, prolonged exposure to moisture can still cause damage over time.
Natural Stain Options for Outdoor Wood
If you want to add a little color to your outdoor wood while still using natural products, consider these stain alternatives:
Coffee or Tea
Brewed coffee or tea can be used as a natural wood stain, providing rich, earthy tones.
- How to Apply: Brew a strong batch of coffee or tea, let it cool, and apply it to the wood using a cloth or brush. Repeat until you reach the desired color.
Vinegar and Steel Wool
Soaking steel wool in vinegar creates a chemical reaction that produces a grayish stain perfect for giving wood a weathered look.
- How to Apply: Place steel wool in a jar of vinegar and let it sit for several hours or overnight. Strain the mixture and apply it to the wood with a cloth.

Protecting Wood from Pests Naturally
In addition to moisture and sun damage, outdoor wood can be vulnerable to pests like termites. Natural pest deterrents include:
Essential Oils
Essential oils like cedarwood, eucalyptus, or tea tree oil can help repel insects. Mix a few drops with water and spray the solution onto your wood to protect it from pests.
Diatomaceous Earth
This natural powder can be sprinkled around the base of wooden structures to deter insects. It’s safe for humans and pets but deadly to pests with exoskeletons.
When to Avoid Natural Treatments
While natural treatments are great for most outdoor wood, there are situations where chemical sealants might be necessary:
- High-Humidity Areas: If you live in an area with extreme humidity or frequent rain, natural oils might not provide enough protection. In these cases, consider using a natural treatment in combination with a more durable, eco-friendly sealant.
- Heavy Wear and Tear: For wood that will be subjected to heavy use or foot traffic, chemical-based treatments might be more suitable to ensure longevity.
That’s it!
Treating wood for outdoor use naturally is not only better for the environment, but it also enhances the natural beauty of the wood. Whether you choose linseed oil, beeswax, or a homemade vinegar solution, these eco-friendly methods offer a safe and effective way to protect your outdoor furniture and structures.
Remember to clean, reapply treatments regularly, and take steps to protect your wood from harsh weather and pests. By following this guide, you can enjoy beautiful, well-maintained wood for years to come!
