Wood is popular with furniture and home decor enthusiasts due to its rich grain and timeless appeal.
Sealing wood is important in its maintenance and longevity, as it acts as a protective barrier, preventing UV rays and environmental pollutants.
Non-toxic and natural sealants offer many benefits, such as being free from harmful chemicals, making them safer for the environment, and enhancing the wood’s natural beauty.
What sealing does and why it’s necessary
Sealing is essentially applying a protective coating to the wood’s surface. This coating acts as a shield, blocking water, dirt, sunlight, and other damaging elements.
As for whether natural wood needs to be sealed, the answer is it depends. It might not require sealing if the wood is indoors and not exposed to moisture or sunlight.
However, sealing is necessary for outdoor furniture, decks, or any wood exposed to the elements to prolong its life and maintain its beauty.
A Look at Different Types of Sealers
Sealers come in various types, each with its unique characteristics and applications.
1. Non-Toxic Sealants for Wood
Non-toxic sealants are a fantastic option for those seeking a safe, eco-friendly solution. They lack volatile organic compounds (VOCs), harmful chemicals in traditional sealants. Beeswax and linseed oil are popular natural, non-toxic choices.
2. Wood Finish for Furniture
When it comes to furniture, you want a finish that protects and enhances the piece’s aesthetic appeal. Natural oil finishes, like tung oil or walnut oil, can deepen the color of the wood and highlight its grain while providing a robust protective layer.
The Importance of Non-Toxic Sealers
Traditional wood sealers have been a go-to for years. However, they come with a hidden cost – toxicity. Many contain VOCs, which release toxic fumes, potentially causing headaches, dizziness, or long-term health effects. They can also harm the environment, contributing to air pollution and ozone depletion.
Advantages of Non-Toxic Sealers
On the other hand, non-toxic sealers are the heroes of the wood sealing world. They are safe, sustainable, and effective. They don’t release harmful fumes, making them safer for indoor use and better for your health. Plus, they’re eco-friendly, causing minimal impact on the environment.
Exploring Non-Toxic Wood Sealers
So, what are some of the top non-toxic wood sealers on the market? Here’s a closer look at a few standout options:
1. Tung Oil
Extracted from the nut of the china wood tree, tung oil penetrates deeply into the wood and hardens upon exposure to air. This creates a clear, almost invisible, water-resistant finish, maintaining the wood’s natural character. Plus, it’s entirely non-toxic and food-safe, making it perfect for kitchen utensils or countertops.
2. Linseed Oil
Linseed oil, derived from flax seeds, is another fantastic non-toxic option. It provides a glossy finish that brings out the grain and warmth of the wood. It’s also easy to apply, requiring just a cloth and some elbow grease. However, remember to choose “raw” linseed oil, as some “boiled” versions can contain added chemicals.
Beeswax is non-toxic and offers a unique, creamy finish that few other sealants can match. It’s especially great for smaller items like cutting boards or toys. Melted beeswax can be easily applied with a cloth and dried to a soft, satin finish, enhancing the wood’s natural beauty.
4. Carnauba Wax
Carnauba wax is a plant-based product that’s often combined with other oils or waxes to make a more durable finish. It’s harder than most other waxes, offering excellent protection against scratches and spills. And of course, it’s non-toxic and safe for use.
Shellac, derived from the secretions of a bug (yes, you read that right!), is a time-tested, non-toxic wood sealer. It dries quickly to a high-gloss finish and is easily repairable. However, it isn’t as durable as other options, so it’s best for pieces that don’t see heavy wear and tear.
DIY Methods for Natural Wood Sealing
For the hands-on folks, DIY natural wood sealing is a rewarding project. Here are a few methods you can try:
1. Beeswax and Mineral Oil Mix
Melt equal parts of beeswax and mineral oil in a double boiler, stirring until well combined.
Allow the mixture to cool slightly before applying with a clean cloth. Let it soak in, then buff for a beautiful, soft sheen.
2. Linseed Oil and Turpentine
Mix two parts linseed oil with one part turpentine for a powerful, penetrating sealer. Apply liberally with a brush, let it penetrate, then wipe off the excess.
3. Homemade Tung Oil Blend
Blend one part tung oil with one part citrus solvent for a potent, non-toxic sealer. Apply with a cloth, rubbing in the direction of the grain, and let dry.
When choosing a natural, non-toxic sealer, remember that every wood piece is unique and may respond differently to different sealers. Test your chosen sealer on a small, hidden area first to ensure it gives the finish you’re after.
