The Definitive Guide to Choosing the Best Clear Sealer for Your Cedar Fence

Cedar fences are a beautiful and durable addition to any property, offering both privacy and aesthetic appeal. However, the natural beauty of cedar can fade over time due to exposure to the elements. To protect your investment and maintain the pristine look of your cedar fence, choosing the best clear sealer for cedar fence is crucial. This guide will delve into the factors to consider when selecting a clear sealer, explore some top product recommendations, and provide practical tips for application to ensure long-lasting protection.

Why Seal Your Cedar Fence?

Cedar, while naturally resistant to decay and insects, is still susceptible to weathering. Without proper protection, your cedar fence can suffer from:

Graying and Fading: UV rays from the sun break down the lignin in cedar, causing it to lose its vibrant color and turn gray.
Moisture Damage: Rain and humidity can lead to warping, cracking, and splitting of the wood.
Mold and Mildew Growth: Damp conditions create an ideal environment for mold and mildew, which can stain and damage the wood.

A clear sealer for cedar fence acts as a protective barrier, preventing these issues and extending the lifespan of your fence. Unlike stains, which add color, clear sealers allow the natural beauty of the cedar to shine through while providing essential protection.

Factors to Consider When Choosing a Clear Sealer

Selecting the best clear sealer for cedar fence requires careful consideration of several factors:

Type of Sealer

There are two main types of clear sealers: oil-based and water-based. Each has its own advantages and disadvantages.

Oil-Based Sealers: These sealers penetrate deeply into the wood, providing excellent protection against moisture. They tend to enhance the natural color of the cedar, giving it a richer, warmer tone. However, they can be more prone to yellowing over time and may require more frequent reapplication.
Water-Based Sealers: Water-based sealers are more environmentally friendly and easier to clean up. They typically dry faster than oil-based sealers and offer good UV protection. They also tend to be less prone to yellowing.

UV Protection

UV rays are a major cause of fading and graying in cedar. Look for a clear sealer for cedar fence that contains UV inhibitors to protect the wood from sun damage. The higher the concentration of UV inhibitors, the better the protection.

Water Repellency

A good clear sealer should be water-repellent, preventing moisture from penetrating the wood. This helps to prevent warping, cracking, and the growth of mold and mildew. Look for sealers that contain water-repellent additives.

Ease of Application

Consider how easy the sealer is to apply. Some sealers can be applied with a brush, roller, or sprayer. Choose a sealer that you are comfortable applying and that is appropriate for the size and complexity of your fence.

Durability

The durability of a clear sealer refers to how long it will last before needing to be reapplied. Look for sealers that are formulated to withstand harsh weather conditions and that offer long-lasting protection. The best clear sealer for cedar fence will offer several years of protection before reapplication is necessary.

VOC Content

Volatile Organic Compounds (VOCs) are chemicals that can evaporate into the air and contribute to air pollution. Consider choosing a low-VOC or zero-VOC sealer to minimize your environmental impact and protect your health. Water-based sealers generally have lower VOC content than oil-based sealers.

Addressing Common Concerns

Many homeowners have questions regarding sealing their cedar fences. Here are answers to some common concerns:

Will a clear sealer change the color of my cedar fence?

Most clear sealers will slightly enhance the natural color of the cedar, making it appear richer and warmer. However, they should not significantly alter the color. Always test the sealer on a small, inconspicuous area of the fence before applying it to the entire surface.

How often should I reapply clear sealer?

The frequency of reapplication depends on the type of sealer used, the climate, and the level of exposure to the elements. Generally, you should reapply sealer every 2-4 years. Inspect the fence regularly for signs of wear and reapply sealer when needed.

Can I apply clear sealer over existing stain?

It is generally not recommended to apply clear sealer over existing stain, as the sealer may not adhere properly. If you want to apply sealer over stain, you will need to remove the stain first. [See also: Removing Old Stain from a Cedar Fence]
