Wood is one of the most timeless materials for outdoor furniture. Its natural warmth and texture bring character to patios, gardens, and decks. However, untreated wood can easily absorb moisture, warp, or decay when exposed to the elements. If you plan to use freshly cut lumber for Outdoor Tables, proper treatment is essential to ensure strength, stability, and long-term beauty.

At Sunstone Outdoor, we combine advanced material preparation with modern protective coatings to produce furniture that maintains its structure and appearance through years of outdoor use. The following guide explains how to treat fresh lumber effectively before using it in outdoor table construction.

1. Understanding the Nature of Fresh Cut Lumber

Freshly cut lumber contains a high percentage of natural moisture — often more than 40%. This moisture makes the wood soft, prone to warping, and susceptible to fungus or insect damage. Before any treatment or assembly, the lumber must be properly dried and conditioned.

There are two main drying methods:

• Air Drying: Stack lumber boards with spacers in a covered, well-ventilated area for several months. The goal is to reduce moisture content to around 12–15%, ideal for outdoor furniture.

• Kiln Drying: A faster industrial process where lumber is dried in a controlled heated chamber to achieve uniform moisture reduction and prevent internal cracking.

Sunstone Outdoor uses kiln-dried hardwoods in its wooden furniture designs to guarantee dimensional stability and resistance to swelling or shrinking under changing weather conditions.

2. Sanding and Surface Preparation

Once the wood reaches proper moisture levels, smooth the surface to open the grain for treatment absorption.

• Start with medium-grit sandpaper (100–120 grit) to remove saw marks.

• Finish with fine-grit (180–220) for a smooth texture.

• Always sand along the grain direction to avoid scratches.

Clean the surface thoroughly with a dry cloth to remove sawdust before applying any sealer or oil.

3. Applying a Wood Preservative

The first layer of protection is a wood preservative that prevents rot, mold, and insect attack.

Choose a clear or tinted oil-based preservative that penetrates deep into the grain. Apply with a brush or sprayer, ensuring complete coverage on all surfaces, including edges and undersides. Allow the wood to dry for at least 24–48 hours before moving to the next step.

For commercial production, like at Sunstone Outdoor, this step often involves pressure treatment, where preservatives are infused into the lumber under high pressure for maximum penetration and long-term protection.

4. Sealing and Waterproofing

After the preservative has set, apply a sealant or water-repellent finish. This creates a barrier against moisture and UV exposure.

Options include:

• Exterior Polyurethane: Offers a clear, glossy finish with excellent abrasion resistance.

• Spar Varnish (Marine-Grade): Flexible and highly durable, suitable for sun and salt exposure.

• Penetrating Deck Sealer: A low-maintenance option for maintaining a natural matte finish.

Apply two to three thin coats, allowing each to dry completely. Lightly sand between coats for smoother adhesion.

5. Finishing with Outdoor Oils or Stains

For enhanced color and UV protection, finish the surface with a tinted outdoor wood oil or semi-transparent stain.

Popular choices include:

• Teak Oil: Restores natural oils lost during drying and provides warm golden tones.

• Linseed or Tung Oil: Deeply nourishes wood fibers while enhancing natural grain.

• Acrylic Outdoor Stains: Provide rich color while offering UV resistance and water protection.

At Sunstone Outdoor, finishes are selected based on both climate and design intent — ensuring the wood complements metal or glass components while retaining its natural charm.

6. Regular Maintenance

Even treated wood requires routine care to maintain appearance and integrity.

• Clean surfaces with mild soap and water every few months.

• Reapply oil or sealer annually to maintain protection.

• Avoid standing water on tabletops and use protective covers during heavy rain or snow.

• Inspect joints and fasteners periodically for signs of loosening or corrosion.

With consistent upkeep, treated lumber tables can last 10–15 years or longer, even in humid or coastal environments.

7. Sustainable Alternatives

For customers seeking an eco-friendly solution, Sunstone Outdoor also offers engineered wood composites and aluminum-frame hybrid designs that replicate the look of natural wood but require less maintenance. These materials combine weather resistance with sustainability, offering the same visual warmth without annual re-oiling.

Conclusion

Treating fresh cut lumber for outdoor tables is a precise process that requires patience and attention to detail. By drying, sealing, and protecting the wood correctly, you can transform raw lumber into a beautiful, long-lasting centerpiece for any outdoor space.
