Best Clear Finish For Outdoor Cedar Furniture

Cedar wood is a popular choice for outdoor furniture due to its natural resistance to rot, decay, and insects. However, even cedar needs protection from the elements to maintain its beauty and longevity. A clear finish can help to enhance the natural grain of the wood, protect it from UV rays, moisture, and dirt, and make it easier to clean. But with so many options on the market, choosing the best clear finish for outdoor cedar furniture can be daunting. This article will explore the key factors to consider when selecting a finish and highlight some of the most popular and effective choices.

Types of Clear Finishes

Clear finishes for outdoor furniture come in various types, each with its unique properties and advantages. The most common types include:

Oil-based Finishes: These finishes penetrate deeply into the wood, providing excellent protection against moisture and UV damage. They offer a rich, natural look and are often preferred for their durability. Popular options include linseed oil, tung oil, and teak oil.
Water-based Finishes: Water-based finishes are eco-friendly and faster drying than oil-based options. They usually have lower VOCs and are easier to apply. However, they may not offer the same level of durability as oil-based finishes. Popular options include acrylic latex and polyurethane.
Varnishes: Varnishes are typically oil-based or water-based and create a hard, protective film over the wood. They provide a high gloss finish and excellent protection against scratches and abrasion. However, varnishes can yellow over time and may not be as breathable as other finishes.
Penetrating Sealer: Penetrating sealers are formulated to soak into the wood without forming a surface film. They offer some protection against moisture and UV damage but don't provide the same level of durability as other finishes. They can be a good option for preserving the natural look and feel of the wood.

Factors to Consider When Choosing a Finish

Several factors should be considered when choosing the best clear finish for outdoor cedar furniture, including:

Durability

Outdoor furniture faces harsh conditions, including sun, rain, snow, and temperature fluctuations. The chosen finish must offer sufficient durability to withstand these elements and protect the wood from damage. Oil-based finishes generally offer greater durability than water-based options.

UV Protection

Sunlight's UV rays can cause cedar wood to fade and crack. A finish with effective UV protection is crucial for maintaining the wood's color and preventing damage. Look for finishes that include a UV inhibitor in their formulation.

Breathability

Cedar wood naturally resists moisture, but prolonged exposure to moisture can lead to rot and decay. A breathable finish allows the wood to dry out naturally, preventing moisture buildup and maintaining its integrity. Oil-based finishes are generally more breathable than water-based options, although some water-based finishes are designed for breathability.

Appearance

The desired appearance of the finished furniture is also a factor to consider. Oil-based finishes often enhance the natural grain of the wood, providing a rich, warm look. Varnishes offer a high gloss finish, while penetrating sealers preserve the wood's natural texture.

Recommended Finishes for Outdoor Cedar Furniture

Based on the factors discussed above, here are some recommended clear finishes for outdoor cedar furniture:

Oil-Based Finishes

Linseed Oil: A traditional choice, linseed oil provides excellent moisture protection and durability. It enhances the natural grain of the wood and offers a warm, golden tone.
Tung Oil: Known for its exceptional durability and water resistance, tung oil is a good choice for furniture exposed to harsh conditions. It creates a natural and attractive finish.
Teak Oil: While technically designed for teak wood, teak oil offers excellent protection for cedar furniture. It penetrates deeply into the wood, providing moisture and UV protection. Its rich, warm tone enhances the appearance of cedar.

Water-Based Finishes

Acrylic Latex: A popular choice for outdoor furniture, acrylic latex provides good durability, moisture resistance, and UV protection. It dries quickly and has low VOCs, making it an eco-friendly option.
Water-Based Polyurethane: Offering excellent durability and a clear, protective barrier, water-based polyurethane is a good choice for furniture that experiences heavy use. It's available in various sheens, allowing for customization.

Penetrating Sealer

Penetrating Oil Sealer: A good choice for preserving the natural look and feel of cedar, penetrating oil sealers offer some moisture and UV protection without creating a surface film.

Ultimately, the best clear finish for outdoor cedar furniture depends on the specific needs and preferences of the homeowner. By carefully considering the factors discussed above, you can choose a finish that will protect your furniture from the elements, enhance its natural beauty, and ensure its longevity.
