Certain do-it-yourselfers may prefer to maintain their outdoor decks themselves. So let’s move on to learning how to seal a composite deck.

Clean composite decking

Prior to sealing your composite deck, thoroughly clean your outdoor deck. to clean your outdoor deck of any dirt, stains, or mold that may be present. Bear in mind that once the composite decking is sealed, any dirt remaining on the surface will be “sealed” into the decking.

When used in composite decking, it can cause the floor to fade, chip, and crack prematurely. If you intend to use a pressure washer, you must be fully aware of the precautions to avoid causing damage to the composite deck.

Choosing a sealer for a composite deck

After thoroughly cleaning the composite decking, the sealing process can begin. It is critical to select the proper composite deck sealer. Water-based sealants are preferred over solvent-based sealants. Two significant advantages exist for water-based sealers. To begin, unlike solvent-based products, they do not stain the composite decking. Second, they employ synthetic resins that inhibit the growth of algae and mold.

Applying the sealer

To keep it clean, brush the sealer while it is still wet. You can apply the sealer with a roller or a sprayer, but always remember to back brush. Apply the sealer with a roller and immediately brush it back. If you choose to spray the sealer, simply complete the back-brushing with a roller. Back-brushing the sealer will increase the composite deck’s surface tension. As a result, the composite becomes more porous and absorbs additional sealer.

The more sealer that is absorbed by the deck’s surface, the longer the coating will last. It is critical to note that you should not use an excessive amount of sealer. Wipe away any excess sealant if you use more than the composite can absorb. Excess residual sealant on the deck surface can create shiny moving spots. As a result, a small amount of excess sealer must be wiped away to ensure a clean appearance. Then, allow at least one day for it to dry. Once the drying process is complete, you can enjoy your composite decking to the fullest!
