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.
Once the surface is dirt free it will be ready to accept new stain. Use a quality composite deck stain that penetrates well. Look for a stain that helps fight against UV fading and discoloring. Composite deck stains with mildewcides or inhibitors are a plus. Any stain containing zinc particles will also naturally fight against mildew. Apply the composite deck stain using a brush, roller, or stain pad. Do not over apply.
Try to stay away from film forming or solid deck stains. These can begin to flake and peel away from the surface after a few months. They are also more prone to mildew problems because they create a film atop the surface that may trap moisture. To keep a composite deck looking good, rewash the deck every couple of seasons and apply a maintenance coat of stain. This will help ensure a clean attractive composite deck for many years to come.
