A clear stain will allow your deck wood to weather naturally with the added bonus of water protection, fade resistance, and durability. It gives an “oiled” appearance which prevents the deck from graying. Clear stains will protect your wood from water damage and mildew, making it easier to clean and maintain. Most clear stains require one thin coat for best results (always check manufacturer recommendations!), and apply best to new wood that is less than 3 years old.
