Understanding Composite Decking
Before discussing whether or not you can apply deck sealer on composite decking, it’s essential to understand how this type of decking is manufactured. Unlike traditional wood decking, composite decking is designed to be moisture-resistant and does not require the same level of sealing and staining to protect it from the elements. This is because the plastic component of composite decking acts as a barrier against moisture and inhibits the growth of mold and mildew.
The Importance of Maintenance
Although composite decking is low maintenance, it is not maintenance-free. Regular cleaning is necessary to remove dirt, debris, and stains that may accumulate over time. Neglecting maintenance can lead to surface discoloration, mold growth, and the breakdown of the protective plastic layer. Therefore, it is crucial to establish a maintenance routine to keep your composite decking looking its best.
Cleaning Composite Decking
The first step in maintaining composite decking is regular cleaning. You can use a soft-bristle brush, mild soap or detergent, and water to clean the surface. Avoid using harsh chemicals or power washers, as they can damage the composite material. Ensure that the cleaning solution is thoroughly rinsed off, as any residue left behind can result in streaks or spots.
Applying Deck Sealer on Composite Decking
While composite decking does not require sealing in the same way as wood, some homeowners may opt to apply a protective sealant for added durability and longevity. However, it is essential to note that not all composite decking manufacturers recommend or warranty the use of deck sealers. Applying a deck sealer may also alter the appearance of the composite decking, potentially making it look shinier or darker.
Selecting the Right Deck Sealer
If you decide to apply a deck sealer to your composite decking, it is crucial to choose the right product. Look for a sealer specifically formulated for use on composite decking or one that is compatible with both wood and composite materials. Read the manufacturer’s instructions carefully to ensure that the sealer is suitable for your type of composite decking.
Applying the Deck Sealer
Before applying the deck sealer, thoroughly clean the composite decking as mentioned earlier. Allow the surface to dry completely before proceeding. Follow the manufacturer’s instructions for application, considering factors such as temperature, drying time, and recommended number of coats. Avoid applying an excessive amount of sealer, as it may not penetrate the composite material and may result in a sticky or tacky surface.
Potential Risks and Considerations
Applying a deck sealer on composite decking may have some potential risks and considerations. First, as mentioned earlier, it may alter the appearance of the decking, leading to a shinier or darker finish. This can be undesirable if you prefer the natural look of the composite material. Additionally, if the sealer does not adhere properly or is incompatible with the composite decking, it may result in an uneven or blotchy appearance.
Warranty Concerns
It is essential to consider the manufacturer’s warranty when contemplating the application of a deck sealer on composite decking. Some manufacturers may void the warranty if sealers or other coatings are applied to the decking surface. Therefore, always check the manufacturer’s guidelines and recommendations before proceeding with any maintenance or enhancement treatments.
While composite decking does not require the same level of sealing and staining as traditional wood decking, some homeowners may choose to apply a deck sealer for added protection and longevity. However, it is crucial to consult the manufacturer’s guidelines and warranty information before proceeding. Proper maintenance, including regular cleaning and removing stains promptly, is key to maintaining the beauty and durability of composite decking.
