What Finish To Use On Outdoor Cedar

Cedar is a popular choice for outdoor projects due to its durability, natural beauty, and pleasant aroma. However, to ensure the longevity and aesthetic appeal of cedar, it requires proper protection and finishing. Choosing the right finish for outdoor cedar is essential to shield it from the elements and maintain its natural charm. There are various options available, each with its own advantages and disadvantages. Understanding the different finishes and their suitability for specific outdoor applications is key to making an informed decision.

Oil-Based Finishes

Oil-based finishes, such as linseed oil, tung oil, and teak oil, are known for their penetrating properties. They soak into the wood, enhancing its natural grain and providing a protective barrier against moisture. Oil-based finishes are typically easy to apply and can be refreshed periodically to maintain their effectiveness. They are suitable for projects where the natural beauty of cedar is desired, such as decks, furniture, and siding. However, oil-based finishes require regular maintenance and can take longer to dry. They may also attract dirt and grime, requiring frequent cleaning.

Semi-Transparent Stains

Semi-transparent stains offer a balance between protection and color. They allow the natural grain of cedar to show through while adding a subtle tint or color. Semi-transparent stains provide a moderate level of protection against UV rays, moisture, and mildew. They are a good choice for projects where a slight color change is desired while maintaining the natural look of cedar. Common applications include decks, fences, and siding.

Solid-Color Stains

Solid-color stains offer the most significant protection for cedar. They provide a solid color coverage, effectively hiding the natural grain of the wood. Solid-color stains offer excellent protection from UV rays, moisture, and mildew. They are often used for projects where a specific color scheme is required or where a longer lifespan is desired. Common applications include decks, fences, and siding.

Water-Based Finishes

Water-based finishes are becoming increasingly popular due to their low VOC content, making them environmentally friendly. They typically dry faster than oil-based finishes and are less likely to create strong odors. Water-based finishes are available in various forms, including stains, sealers, and paints. However, they often require more coats for adequate protection and may not be as durable as oil-based finishes.

Choosing the Right Finish

The optimal finish for outdoor cedar depends on several factors: * **Desired level of protection:** Consider the amount of protection required against UV rays, moisture, and mildew. Solid-color stains offer the highest level of protection, while oil-based finishes offer moderate protection. * **Aesthetic preference:** If the natural beauty of cedar is desired, oil-based finishes or semi-transparent stains are suitable. For a specific color scheme, solid-color stains are the best option. * **Maintenance considerations:** Oil-based finishes require regular maintenance, while solid-color stains provide a longer lifespan with less frequent maintenance. * **Application environment:** Consider the environmental conditions where the cedar will be exposed. If the climate is hot and humid, a finish with good mildew resistance is essential.

It is crucial to follow the manufacturer's instructions for application and drying time. Properly preparing the cedar surface before applying any finish is also essential for optimal adhesion and durability. Consulting with a professional wood finishing expert can provide valuable insights and help select the appropriate finish for specific outdoor projects.
