Step 9 · Apply a Deck Sealant or Stain (Optional)

Once the deck is completely dry, you can apply a protective sealant or stain. Choose a product appropriate for your deck's material and desired finish. Apply the sealant or stain evenly using a brush, roller, or sprayer, following the manufacturer's instructions. Typically, one or two thin coats are recommended. Ensure you maintain a 'wet edge' to avoid lap marks. Allow adequate drying time between coats and before replacing furniture.
