Sealing Your Fence: A Comprehensive Guide

Sealing a fence is a crucial maintenance task that can extend its lifespan and maintain its aesthetic appeal. If you run a fence company or are a DIY enthusiast, understanding the best practices for sealing your fence can be invaluable. In this article, we will explore the methodologies, materials, and best practices for sealing different types of fences, with a particular focus on cedar fences.

The Role of Sealing in Fence Maintenance

In my experience, managing a fence company since 2000, I have had the opportunity to observe the effectiveness of various sealing products on wooden fences. Cedar fences, in particular, are a common choice for their longevity and natural beauty. However, not all sealants are created equal.

Effective Sealants for Cedar Fences

One of the most important decisions when sealing a cedar fence is the choice of sealer. While there are many options available, some are more effective than others. Traditional water sealers, such as those sold by Thompson's, often fall short in their ability to protect the wood. Instead, I have found that using an oil-based stain, such as those offered by Sherwin-Williams, can significantly enhance the appearance and longevity of a cedar fence.

Personal Experience with Oil-Based Stain

When I applied Sherwin-Williams oil-based stain to my cedar fence, I noticed a marked improvement in its appearance and how well it held its color. This oil-based stain helped the fence maintain its fresh look for an additional five years. Despite this improvement, it is essential to note that the ultimate longevity of the fence remained unchanged. The wood still rots at the ground level, but the stain provides a worthwhile cosmetic benefit.

Preparation and Application

The success of sealing a fence largely depends on proper preparation and application. Here are the steps to follow:

1. Choose the Right Sealer

For cedar fences, opt for a high-quality oil-based stain or an outdoor deck and fence sealer with a long lifespan. Water-based products may offer better color retention but might be less effective in protecting against mold and mildew.

2. Clean the Fence

Thoroughly clean the fence to remove dirt, debris, and old sealant. This ensures that the new sealer adheres properly.

3. Apply the Sealer

For a professional look, use an airless spray rig. However, if you don't have access to this, a high-quality brush works just as well. Be sure to apply the sealer evenly and in thin coats to avoid sagging or drips.

Alternative Sealing Methods

The choice of sealer can vary depending on the type of wood and your specific needs. Here are some considerations:

Cedar Fences

Regularly seal cedar fences with a deck and fence sealer to maintain their appearance.

Remember that cedar will naturally gray over time, which can be a desirable aesthetic effect. If you prefer to avoid this, choose a sealer that offers more color retention.

Pressure Treated Lumber

Pressure-treated lumber typically requires less sealing than natural wood. However, if you want a different color, a sealer or stain can enhance its appearance.

Conclusion

Sealing your fence is a vital step in maintaining its visual appeal and extending its lifespan. By choosing the right sealer and applying it correctly, you can protect your investment and enjoy the beauty of your fence for many years to come. Whether you are a professional fence installer or a DIY enthusiast, this guide should provide you with the necessary knowledge to achieve optimal results.
