What Causes Deck Deterioration?

There are several factors that contribute to the deterioration of your deck, including:

  • Weather: Extreme temperatures, precipitation, and exposure to sunlight can cause wood to expand, contract, and warp over time.
  • Moisture: Water can penetrate the wood, leading to rot, mold, and mildew growth.
  • UV Rays: Sun exposure can cause wood to fade, dry out, and become more susceptible to cracking.

By using a deck sealer, you can help protect your deck from these damaging effects and prolong its life.

What is a Deck Sealer and How Does It Work?

A deck sealer is a protective coating that is applied to the surface of your deck to help shield it from moisture, UV rays, and other environmental factors. The sealer forms a barrier on the wood’s surface, preventing water and other elements from penetrating and causing damage.

There are three main types of deck sealers:

  • Clear sealers: These provide a transparent finish that allows the natural wood grain to show through. Clear sealers need to be reapplied more frequently than other types, typically every 1-2 years.
  • Semi-transparent sealers: These offer a subtle tint and provide more UV protection than clear sealers. Semi-transparent sealers typically need to be reapplied every 2-3 years.
  • Solid stain sealers: These provide the highest level of UV protection and are available in a wide range of colors. Solid stain sealers need to be reapplied every 3-5 years. 

Benefits of Deck Sealing

Deck sealing offers several benefits, including:

  • Protection: A sealer forms a protective barrier that helps prevent water, UV rays, and other elements from causing damage to your deck.
  • Enhanced appearance: Deck sealers can improve the look of your deck by highlighting the natural wood grain or adding a touch of color.
  • Increased lifespan: By protecting your deck from the elements, a sealer can help prolong its life and reduce the need for costly repairs.
  • Easier maintenance: Sealed decks are easier to clean and maintain, as the sealer helps prevent dirt, grime, and debris from penetrating the wood.

Choosing the Right Sealer for Your Deck

When selecting a deck sealer, consider the following factors:

  • Deck material: Different types of wood require different sealers. Be sure to choose a sealer that is specifically designed for your deck’s material.
  • Climate: Consider the weather conditions in your area. If your deck is exposed to harsh sunlight or heavy rain, you may need a sealer with enhanced UV protection or water resistance.
  • Desired appearance: Determine whether you prefer a clear, semi-transparent, or solid stain sealer, depending on the look you want to achieve.
  • Maintenance requirements: Consider how often you’re willing to reapply the sealer, as some types require more frequent applications than others.


Sealing your deck is a vital step in maintaining its appearance and structural integrity. By understanding the basics of deck sealing and choosing the right sealer for your needs, you can help protect your investment and enjoy your outdoor living space for years to come.
