Clean the Composite Deck:

Before you start applying paint on the composite deck, you need to sweep excess debris like dirt and leaves off the deck.

Once the composite deck is properly cleaned, you need to apply a good quality composite deck stain. Make sure you stir the stain thoroughly before using. You also need to make sure that all stain in the product is mixed evenly into the stain. If you use paint, make sure you use the top quality exterior latex coating. In case you want to use oil-based product over the latex coating, you should be careful, otherwise the oil coating may develop cracks that can ruin the appearance of the deck.
