Application Tools

• Garden sprayer (optional)

Step-by-Step Application

Protect Surrounding Areas

• Cover nearby plants, furniture, and surfaces with drop cloths or plastic sheeting to protect them from overspray or drips.

Apply the Sealer or Stain

• If using a brush: Start by applying the product along the edges and in the gaps between boards. Then, use a brush to apply the sealer or stain to the deck surface, working in small sections. Brush in the direction of the wood grain for even coverage.
• If using a roller: Pour the sealer or stain into a paint tray. Use a roller to apply the product evenly across the deck surface, again working in the direction of the wood grain.
• If using a garden sprayer: Fill the sprayer with the sealer or stain and apply a thin, even coat to the deck surface. Follow up with a brush to ensure even coverage and to work the product into the wood grain.

Allow to Dry

• Allow the first coat to dry completely according to the manufacturer’s instructions, typically 24-48 hours.
• If applying a second coat, ensure the first coat is fully dry before application.

Final Touches

• Once the sealer or stain is completely dry, remove any protective coverings from surrounding areas.
• Replace furniture and decor on the deck and enjoy your freshly cleaned and protected outdoor space.
