Best Finish for Outdoor Cedar Furniture: An Expert Guide

Outdoor cedar furniture is the quintessence of elegance and durability. However, choosing the right finish is paramount to maintaining its charming allure and integrity against weather elements.

A suitable finish enhances the furniture’s appearance and offers protection against UV rays, mildew, and moisture, common threats to outdoor furniture.

This guide offers an in-depth look into the importance of finishes and why cedar makes the perfect material for outdoor furniture.

Why Use Cedar For Outdoor Furniture?

Cedar, renowned for its natural beauty and durability, is a powerhouse in outdoor furniture. But what exactly makes cedar the go-to choice for many?

Firstly, cedar possesses impressive weather-resistant properties.

Outdoor furniture is exposed to varying weather conditions—scorching heat, chilling cold, heavy rainfall—and the material must withstand these elements.

Cedar’s inherent oil content is a natural deterrent to moisture, reducing the risk of decay and rot. This means your cedar furniture can braver the elements while maintaining structural integrity.

Secondly, cedar is naturally resistant to insects.

Any outdoor furniture is a potential playground for critters. Cedar, however, is a formidable foe to these unwanted guests. Its natural oils act as a repellent, deterring insects and reducing the risk of infestation.

Another key benefit of cedar is its lightweight yet robust nature.

Compared to other types of wood, cedar is surprisingly light, making it easy to move or reposition your furniture. Despite its lightness, cedar is incredibly sturdy, promising longevity to its owners.

Cedar also stands out for its distinct aesthetic appeal.

It boasts warm, earthy tones, ranging from light amber to rich honey and deep cinnamon. This natural palette makes cedar furniture a visually pleasing addition to any outdoor space, complementing different design styles.

The rich aroma of cedar is another feature to celebrate.

This pleasant scent is a sensory delight and contributes to the wood’s insect-resistant properties.

Cedar’s low maintenance requirement is the icing on the cake.

While it’s true that all outdoor furniture demands some level of upkeep, cedar’s requirements are minimal. A simple cleaning routine and finish can keep your cedar furniture looking top-notch for years.

Specific properties of cedarwood

Now that we’ve explored why cedar is an excellent choice for outdoor furniture let’s delve into the finishes world.

Which types of wood can be used untreated?

Types of Finishes for Outdoor Cedar Furniture

Choosing the right finish is essential to preserve the beauty and extend the lifespan of your outdoor cedar furniture.

With many available options, deciding which is the best can be overwhelming. This guide will walk you through the top picks, discussing their advantages, disadvantages, and specific examples in each category.

Oil Finishes

Oil finishes are the traditional go-to for woodworkers, offering natural protection and enhancing the wood’s inherent beauty. They seep into the wood’s fibers, bolstering durability while enriching the cedar’s natural colors.

However, while oils offer moisture resistance, they may not offer as much protection against UV rays or heavy weather conditions as other finishes. Additionally, they require periodic reapplication to maintain their protective qualities and aesthetic appeal.

Danish oil is a blend of oil and varnish, providing penetrating and surface-level protection. Danish oil on cedar accentuates the wood’s rich tones while offering decent water and UV resistance.

Linseed oil, particularly the boiled variety, is another favorite for cedar. It penetrates the wood, providing water resistance and a slight golden tint. However, if not properly maintained, linseed oil on cedar can slowly dry and attract mildew.

Tung oil, derived from the nuts of the Tung tree, penetrates deeply into the wood and hardens upon exposure to air. Tung oil on cedar is an excellent choice for outdoor cedar furniture due to its water resistance and non-toxic nature.

Many woodworkers highly recommend using teak oil when finding the best oil for western red cedar. This oil is known for its ability to deeply penetrate the wood and provide UV resistance, making it an excellent choice for outdoor furniture made with this type of cedar.

In general, the best oil for outdoor cedar furniture offers a balance of protection, enhancement of the wood’s natural beauty, and ease of maintenance. Depending on the specific needs of your furniture, Danish oil, linseed oil, tung oil, or teak oil could all be contenders for the best oil treatment for cedar.

Sealers

Sealers, as the name suggests, seal the wood’s surface to create a protective barrier against moisture, UV rays, and other damaging elements. They work by filling in the wood’s pores to prevent water absorption, making them an excellent choice for outdoor cedar furniture.

However, sealers might not enhance the wood’s color or grain as much as oils or stains. They also require more frequent reapplication, especially in areas with heavy weather exposure.

When sealing a cedar tabletop, the process typically involves thoroughly cleaning the surface, lightly sanding it, and then applying the sealer using a brush or spray. The same steps apply when sealing an outdoor cedar table or furniture.

Seal-Once Marine Wood Sealer is a favorite among cedar furniture owners. It’s a water-based sealer that protects against water damage and decay. Plus, it’s eco-friendly and safe for use around pets and plants.

Ready Seal Exterior Stain and Sealer for Wood is another notable product that combines a stain’s color enhancement with a sealer’s protective qualities. It’s oil-based, offering excellent water resistance and UV protection.

Clear Finishes

Clear finishes are all about showcasing the natural beauty of the cedar. They provide a protective layer without adding color, allowing the wood’s natural tones and grain to take center stage.

However, clear finishes might not offer as much UV protection as some colored finishes. And, like other finishes, they require regular maintenance to maintain their protective qualities.

A clear finish designed for exterior use is crucial for outdoor cedar furniture. General Finishes Outdoor Oil is an excellent choice, offering water resistance and a subtle amber

glow that amplifies the cedar’s natural beauty without masking it.

Another option is Thompson’s WaterSeal Clear Wood Protector, which provides powerful protection against water damage and mildew while maintaining the wood’s natural appearance.

Varnishes and Urethanes

Varnishes and urethanes create a hard, protective film on the wood’s surface that offers superior protection against moisture, UV rays, and physical wear. They’re an excellent choice for outdoor cedar furniture that needs high durability.

However, these finishes might obscure the wood’s natural texture due to their film-forming nature. They can also be more challenging to apply and maintain than oils or sealers.

Minwax Helmsman Spar Urethane is a popular choice for outdoor cedar furniture. It’s designed for exterior wood exposed to sunlight, water, and temperature changes. This urethane forms a protective barrier against rain and moisture, while its UV blockers reduce the sun’s graying and fading effects.

Zar Exterior Water-Based Polyurethane is another excellent option, providing robust protection against the elements in a clear finish that doesn’t yellow over time. It’s a great way to preserve the natural beauty of cedar while ensuring its longevity.

Choosing the right finish for outdoor cedar furniture balances aesthetics with protection.

Oils, sealers, clear finishes, varnishes, and urethanes have strengths and potential drawbacks. Consider the specific needs of your furniture, the climate in your area, and your personal preferences when making your choice.

Cedar oil for an outdoor finish

Cedar is a rewarding type of wood that you can use for many applications. It is durable but quickly weathers under the influence of sun and rain and then takes on a silver-grey look that is often blotchy.

Painting cedar or treating it with a film-forming oil is not always a good idea. Due to the rapid weathering, the chance of early peeling is high.

That is why Cedar Oil was developed, a non-film-forming stain that gives cedar wood an even look. Cedar oil is available in many colors, but choosing a white or gray shade is best for the best and most durable result.

Cedar oil can be painted over after 16 to 24 hours, depending on temperature and humidity.

Apply Cedar oil with a flat (long-haired) brush or spray in 1 or 2 undiluted layers according to the desired appearance.
