Why You Need Deck Cleaner before Staining
Before you can apply the stain, you need to make sure the deck is cleaned using deck cleaner. The surface should be clean with no wood fibers, grease, dust, or dirt. It also needs to be dry and free of mildew. When the surface is not properly cleaned, the stains will have trouble sticking and could end up peeling.
Before you apply deck cleaner, be sure to sweep the deck to remove any debris ad leaves. Then liberally apply the cleaner using a pump sprayer or roller. If you have a large deck, it’s best to work in small sections to make sure the area is constantly wet. Allow the cleaner to set for 15 minutes and keep it wet with the mist of a garden hose to have the cleaner soak into the wood. If you encounter grease stains, use a mild detergent. After 15 minutes, work the cleaner into the surface and scrub to remove all residue. Use a garden hose to rinse off cleaner from the deck. When the deck is dry, sand any areas and remove any additional residue before staining.
