How To Seal Cedar Fence

How to Seal a Cedar Fence: A Comprehensive Guide

Cedar is a beautiful and naturally durable wood, making it a popular choice for fencing. However, even cedar needs protection from the elements to maintain its stunning appearance and longevity. Sealing your cedar fence is crucial for preventing weathering, cracking, warping, and insect damage. This guide will walk you through the process, ensuring your fence stays strong and beautiful for years to come.

Preparing Your Cedar Fence for Sealing

Before you even think about grabbing your sealant, proper preparation is key. This will ensure the sealer adheres properly and lasts longer.

1. Cleaning the Fence:

Thoroughly cleaning your fence removes dirt, mildew, cobwebs, and any existing loose paint or sealant. Use a stiff-bristled brush, a pressure washer (on a low setting to avoid damage), or a combination of both. For stubborn mildew, consider a solution of water and mild bleach (always follow the manufacturer's instructions). Allow the fence to dry completely before proceeding. This is crucial for proper sealant adhesion.

2. Repairing Damage:

Inspect your fence carefully for any damaged boards, loose nails, or gaps. Repair any damaged areas before sealing. Replace rotten or severely damaged boards, and secure loose ones. Filling gaps with wood filler will prevent moisture intrusion. Allow the wood filler to fully cure before sealing.

Choosing the Right Sealer for Your Cedar Fence

The type of sealer you choose depends on your desired outcome and the climate in your area.

1. Types of Sealants:

• Water-based sealants: These are typically easier to clean up, have less odor, and are environmentally friendly. They offer good protection against moisture but may not be as durable as oil-based options in harsh climates.

• Oil-based sealants: These sealants penetrate deeper into the wood, offering superior protection against moisture and UV rays. They tend to be more durable but have a stronger odor and require mineral spirits for cleanup.

• Solid-color stains: These combine the protective qualities of a sealant with the aesthetic enhancement of a stain, adding color and depth to your cedar fence.

• Transparent sealants: These protect the wood without altering its natural color, allowing the beautiful grain of the cedar to shine through.

2. Considering Your Climate:

If you live in a particularly humid or rainy area, an oil-based sealer might be a better choice for its superior water resistance. In drier climates, a water-based sealant could suffice.

Applying the Sealer:

With your fence prepared and your sealer chosen, it's time to apply the sealant.

1. Applying the Sealant:

Use a high-quality brush, roller, or sprayer to apply the sealant evenly and smoothly. Follow the manufacturer's instructions carefully regarding application methods and drying times. Work in small sections to prevent the sealant from drying before you can spread it evenly.

2. Multiple Coats:

Most sealants require two coats for optimal protection. Allow the first coat to dry completely before applying the second. This ensures thorough protection and a uniform finish.

3. Clean-Up:

Clean up any spills or drips immediately using the appropriate solvent (water for water-based sealants, mineral spirits for oil-based sealants).

Maintaining Your Sealed Cedar Fence

While sealing your fence provides excellent protection, regular maintenance will extend its lifespan.

1. Regular Inspection:

Inspect your fence periodically for any signs of damage, wear, or peeling sealant. Address any issues promptly to prevent further problems.

2. Resealing:

Depending on the type of sealant and the climate, you may need to reseal your fence every 2-3 years. This will maintain its protection and extend its lifespan.

By following these steps, you can ensure your cedar fence remains a beautiful and functional part of your property for many years to come. Remember, proper preparation and the right sealant are key to achieving long-lasting results.
