Protecting your outdoor wood furniture from the elements while enhancing its natural beauty requires the right finish. The best choice depends on the type of wood, the level of protection you need, and the aesthetic you desire. This guide covers everything you need to know to choose the perfect finish for your outdoor wood furniture, ensuring its longevity and stylish appeal.
Understanding the Importance of Outdoor Wood Protection
Solid wood furniture offers unmatched durability and aesthetic appeal compared to alternatives like plastic or metal. Woods like teak, cedar, and redwood are naturally resistant to decay and insects, making them ideal for outdoor use. However, even the most durable woods need protection from the elements. Without proper finishing, outdoor wood furniture can suffer from: Sun Damage: UV rays cause fading and discoloration. Water Damage: Rain and humidity lead to warping, cracking, and rot. Mold and Mildew: Moisture creates an ideal environment for growth. Insect Infestation: Pests can burrow into the wood, causing structural damage.
Choosing the right finish and maintaining it regularly will extend the life of your outdoor furniture, preserving its beauty for years to come.
Types of Wood Finishes for Outdoor Furniture
Several types of wood finishes offer varying levels of protection and aesthetic appeal. Here's a breakdown of popular options: Penetrating Oils: These oils, such as teak oil, linseed oil, and tung oil, soak into the wood fibers, providing protection from within. They enhance the wood's natural grain and offer a warm, matte finish. Penetrating oils are easy to apply and maintain but require regular reapplication (typically every few months) for optimal protection. Spar Urethane: This varnish is designed for marine applications and offers excellent water resistance and UV protection. Spar urethane creates a durable, flexible film on the surface of the wood, preventing moisture from penetrating. It's ideal for furniture exposed to harsh weather conditions. However, it can be prone to scratching and may require more skill to apply evenly. Exterior Wood Stains: Stains contain pigments that add color to the wood while also providing a degree of protection. They penetrate the wood pores, highlighting the grain and offering resistance to fading and weathering. Choose a stain specifically formulated for exterior use, containing UV inhibitors and water repellents. Stains are available in various opacities, from transparent to solid. Exterior Paint: Paint provides the most comprehensive protection against the elements. It forms a thick, opaque layer that shields the wood from sun, rain, and temperature fluctuations. Exterior paints are available in a wide range of colors and finishes (e.g., matte, satin, gloss). However, paint can obscure the wood's natural grain and may require more extensive preparation and application. Water-Based Acrylic Finishes: These finishes are becoming increasingly popular due to their low VOC content, ease of application, and durability. Water-based acrylics offer good UV protection and water resistance. They also tend to be more flexible than oil-based finishes, reducing the risk of cracking and peeling. Wood Sealers: Wood sealers are designed to create a protective barrier against moisture, preventing water from penetrating the wood. They are often used as a primer before staining or painting, but some sealers can also be used as a standalone finish. Look for sealers specifically formulated for exterior use.
Choosing the Right Finish for Your Wood Type
The best finish depends on the type of wood your furniture is made from: Teak: Teak is naturally oily and highly resistant to decay, so it doesn't require a finish for protection. However, applying teak oil can enhance its natural color and prevent it from weathering to a silver-gray patina. Cedar: Like teak, cedar is naturally durable and doesn't require a finish for protection. However, a clear wood preservative or stain can help maintain its color and prevent weathering. Pine: Pine is a softwood that requires a more robust finish to protect it from the elements. Exterior paint or a high-quality stain with a water-resistant sealant is recommended. Oak: Oak is a hardwood that is relatively durable but still needs protection from moisture. Spar urethane or a high-quality exterior stain with a sealant are good choices. Acacia: Acacia is a durable hardwood suitable for outdoor use. While it can be left unfinished to develop a silver-gray patina, applying a penetrating oil or exterior stain can enhance its natural color and provide added protection. Eucalyptus: Eucalyptus is a fast-growing hardwood often used in outdoor furniture. Applying a penetrating oil or exterior stain helps protect it from moisture and UV damage, prolonging its lifespan and maintaining its appearance.
Step-by-Step Guide to Refinishing Outdoor Wood Furniture
Refinishing is necessary when the existing finish is worn, damaged, or you simply want to change the look of your furniture. Here's a step-by-step guide:
1.Preparation:
Clean the Furniture: Remove dirt, mildew, and loose debris with a scrub brush and a mixture of soap and water. Rinse thoroughly and allow the furniture to dry completely.
Remove Old Finish: Depending on the type of finish, you may need to sand, scrape, or use a chemical stripper to remove the old coating. For paint or varnish, start with a coarse-grit sandpaper (80-100) and gradually move to finer grits (120-180) to smooth the surface.
Repair Damage: Fill any cracks, holes, or gouges with wood filler. Allow the filler to dry completely and sand it smooth.
2.Application:
Apply Stain (Optional): If you want to stain the wood, apply it evenly with a brush, rag, or sprayer. Allow the stain to penetrate for the recommended time (as per the manufacturer's instructions) and wipe off any excess.
Apply Finish: Apply the chosen finish according to the manufacturer's instructions. For penetrating oils, apply liberally and allow the wood to absorb the oil for 15-20 minutes. Wipe off any excess. For varnish, paint, or acrylic finishes, apply thin, even coats with a brush, roller, or sprayer. Allow each coat to dry completely before applying the next.
3.Finishing Touches:
Sand Lightly: After each coat of varnish, paint, or acrylic finish, lightly sand the surface with fine-grit sandpaper (220-320) to remove any imperfections.
Apply Additional Coats: Apply two to three coats of finish for optimal protection.
Clean Up: Dispose of rags and brushes properly. Allow the furniture to cure completely before using it.
