Absolutely! Caring for your wooden outdoor benches doesn't require harsh chemicals. Several effective and environmentally friendly options can protect your benches while keeping your garden safe for people, pets, and pollinators.
For routine care and nourishment, natural plant-based oils are excellent. Tung oil, derived from nut seeds, and linseed oil, pressed from flax seeds, penetrate deeply to repel water and highlight the wood's grain. Look for pure, "raw" or "polymerized" versions without added solvents. For a popular ready-made blend, many choose plant-based decking oils formulated with renewable resources.
Creating a natural wood preservative at home is also possible. A classic recipe combines pine tar, linseed oil, and citrus solvent. This mixture mimics traditional treatments, offering robust weather resistance. Always test on a hidden area first.
For a protective seal, consider waxes made from carnauba palm or beeswax, often blended with oils. While requiring more frequent reapplication, they provide a beautiful, non-toxic finish. Milk paint followed by a natural oil topcoat offers a colorful, durable, and completely biodegradable option.
Sustainable practices are as crucial as the products. Lightly sanding the wood before application ensures better absorption. Regular cleaning with a vinegar solution prevents mildew. The most eco-friendly step is choosing FSC-certified or reclaimed wood when purchasing or building new benches, ensuring responsible sourcing.
By opting for these green solutions, you extend the life of your benches beautifully and responsibly, creating a healthier outdoor sanctuary for all.
