1. Clean the deck with scrubs.Use a deck cleaner and a stiff brush to scrub away any dirt, debris, or mildew. Rinse the deck thoroughly with water and allow it to dry completely.
2. Sand the deck.This step is optional, but it will help to smooth out the surface of the deck and ensure that the stain adheres properly. Use a sander with a medium-grit sandpaper.
3. Apply a pre-conditioner.A pre-conditioner will help to prepare the deck for staining by evening out the absorption rate of the wood. Apply the pre-conditioner according to the manufacturer's instructions.
4. Apply the stain and sealant.Stir the stain thoroughly before applying it. Use a brush or roller to apply the stain in thin, even coats. Be sure to follow the instructions for coverage and drying time. Once the stain has dried completely, apply a sealant to protect it from fading and wear.
