How To Solid Stain Composite Decks Board

While there is a common misconception that composite decking requires no maintenance, the reality is that, like any outdoor surface, it is susceptible to fading and staining over time due to exposure to the elements.

However, the good news is that a faded composite deck can be quickly revitalized and given a fresh lease of life by applying a new stain. This simple yet effective solution allows you to recolor the deck, restoring its vibrancy and enhancing its overall appearance.

By investing a little time and effort into staining your composite deck, you can not only combat the effects of fading but also provide a layer of protection against future wear and tear. The choice of stain color affords you the opportunity to breathe new life into your outdoor space, creating a look and feel that suits your taste and complements the surrounding environment.

So, don’t let the notion of maintenance-free composite decking mislead you. Embrace the power of staining and unlock the potential to preserve and transform your composite deck, ensuring it remains a beautiful and inviting outdoor sanctuary for you and your guests to enjoy.

First Step: Deal With Any Cracks In The Composite Decking

Prior to undertaking any additional steps, it is crucial to address any existing cracks in the composite decking. While composite boards are engineered to be resistant to cracking, it is vital to note that they are not entirely impervious to it.

Various factors, such as the pressure exerted by a settling foundation or a flawed design, can contribute to the formation of cracks. Additionally, day-to-day usage or the presence of defective pieces can also result in the development of cracks.

To ensure the longevity and structural integrity of your composite decking, it is paramount to thoroughly examine the surface for any cracks or signs of damage. This proactive approach allows you to identify and rectify any issues promptly, preventing further deterioration and potential safety hazards.

By implementing this essential first step, you can effectively safeguard your composite decking against the detrimental effects of cracks, thus maintaining its aesthetic appeal and functional longevity.

Remember, a well-maintained and crack-free deck not only provides an inviting and safe outdoor space but also enhances the overall value and enjoyment of your home.

First Step: Clean The Composite Decking

The first step in maintaining your composite decking is to ensure it stays clean and free from any unwanted debris. While this step may be unnecessary if your decking is newly installed and lacks any coating, it becomes essential for decks that have been in use for a while. To effectively maintain its pristine condition, it is highly recommended to follow the cleaning guidelines provided by most manufacturers.

Regularly washing your deck with a soft-bristled brush and soapy water is a simple yet effective approach to keep it free from dirt, bird droppings, or leaves that may accumulate over time. Alternatively, you can opt for a commercial deck cleaner, but it is crucial to choose a gentle product that does not contain caustic chelating detergents, as these may potentially harm the deck’s surface over time. The right cleaner will effectively eliminate spills and dirt without the need for excessive scrubbing.

In instances where your deck requires more intensive cleaning due to a significant amount of dirt or mold, you can cautiously consider utilizing a pressure cleaner to aid the process. However, it is crucial to exercise caution to prevent any damage. Keep the pressure at a minimum and maintain a distance of at least 12 inches between the pressure washer head and the deck’s surface. Be mindful that excessive pressure or improper technique may result in marks on the decking, so always clean along the length of the board, not across it.

By adhering to these cleaning practices, you can ensure your composite decking remains visually appealing, free from contaminants, and in optimal condition for long-term enjoyment. Regular cleaning not only enhances the deck’s aesthetics but also helps in maintaining its overall durability and performance.

Second Step: Apply Composite Deck Sealer

The second step in the maintenance of your composite deck involves the application of a composite deck sealer, which can be done once the deck has completely dried over a few days. For best results, opt for a water-based sealer that will effectively protect and enhance the appearance of your deck. To prevent the growth of mildew, choose a sealer that contains synthetic resin-based components or consider using a percarbonate wood cleaner.

When applying the sealer, it is recommended to brush it onto the deck while it is still wet. This technique not only aids in achieving a clean and uniform look but also helps the sealer to penetrate and adhere to the surface effectively.

Before proceeding with the application, take necessary precautions to protect any nearby grass, plants, concrete trim, or other areas that you don’t want to be stained in the process. Cover them carefully to prevent any accidental staining. Additionally, ensure that you thoroughly stir the sealer before application. This important step ensures that all the pigments and components within the sealer are thoroughly mixed, resulting in an even and consistent finish.

By following these two simple steps, you can effectively seal and protect your composite deck, prolonging its lifespan and retaining its beauty for years to come. With a well-maintained and sealed deck, you can enjoy outdoor moments with peace of mind, knowing that your deck is protected against the elements and looking its best.


In conclusion, taking the necessary steps to maintain your composite decking is essential for its longevity and aesthetic appeal. By following proper cleaning routines, addressing any cracks, and applying a protective sealer, you can ensure that your deck remains in pristine condition for years to come.

Regular cleaning with soapy water or a commercial deck cleaner will keep your deck free from dirt and grime, while addressing any cracks promptly will prevent further damage and maintain the structural integrity of the decking. Applying a composite deck sealer, preferably water-based and with synthetic resin-based components, adds an extra layer of protection against fading, staining, and mildew growth.

With these maintenance measures in place, your composite deck can withstand the elements and continue to provide a beautiful and functional outdoor space. Remember to follow manufacturer guidelines, protect nearby areas during the sealing process, and thoroughly stir the sealer before application for optimal results.

Investing time and effort into maintaining your composite decking will pay off in the long run, as it will remain a welcoming and safe environment for relaxation, entertainment, and enjoyment with family and friends. So, embrace these maintenance practices and let your composite deck shine, ensuring years of outdoor bliss.
