Composite material decks have become very popular among homeowners in the past few years. They come in many different designs and colors. Most people believe that a composite deck is maintenance free but that is not true. Like any surface exposed to Mother Nature, composite decking is prone to fading, graying, warping, and so on. To stop these negative effects a composite deck stain should be applied. Staining composite decks helps block out color fading UV rays and damaging moisture.
To stain a composite deck the surface must first be completely cleaned. With the use of a pressure washer or scrub brush and a composite deck cleaner, all the dirt, mold, mildew, and graying should be washed away. Mildew is a common occurrence on composite materials. Because most composite decking consists of wood and plastic it is prone to mold and mildew. It is important to remove any mildew before staining the deck so mildew is not sealed in and trapped below the surface.
