Weatherproofing a painted or stained deck involves several crucial steps to ensure the wood is protected from unpredictable elements. Scholars Edge Painting takes weatherproofing seriously to ensure that your paint or stain lasts for years to come. Here’s a comprehensive guide to weatherproofing your deck effectively.


The first step in weatherproofing your deck is thorough preparation. Begin by clearing the deck of all furniture, plants, and any other items. Inspect the deck for any damaged boards, loose nails, or screws, and make necessary repairs. Next, clean the deck surface thoroughly using a deck cleaner or a mixture of water and mild detergent. Scrub the surface with a stiff-bristle brush to remove dirt, mold, mildew, and any old stain or paint. Rinse the deck thoroughly with a garden hose or pressure washer and allow it to dry completely.

Remove Old Finish (if necessary)

If the deck has an old finish that needs to be removed, start by scraping off any loose or peeling paint or stain with a paint scraper. Sand the surface to smooth out rough spots and remove any remaining old finish. Begin with coarse sandpaper and move to a finer grit for a smooth finish. After sanding, sweep or vacuum the deck to remove all sanding dust.

Apply Stain or Paint

Choose a high-quality exterior wood stain or paint designed specifically for decks. Some products combine stain and sealant in one. Scholars Edge Painting recommends Sherwin-Williams paint products. Stir the stain or paint thoroughly before application. Use a paintbrush to cut in around edges and tight spots, and a roller for larger surfaces to ensure even application. Follow the wood grain for best results. Allow the first coat to dry according to the manufacturer’s instructions.

Apply Weatherproofing Sealant (if needed)

If your stain or paint does not include a sealant, select a weatherproofing sealant designed for exterior wood. Use a paintbrush or roller to apply the sealant evenly across the deck. Follow the manufacturer’s instructions for drying time and the number of coats needed. Ensure the deck is fully dry before using it again.

Tips for Success

To ensure the best results, perform the weatherproofing project on a dry day with moderate temperatures. Avoid working in direct sunlight or when rain is expected. Regular maintenance is key; regularly clean your deck and reapply the weatherproofing sealant as needed to keep it looking fresh and protected.
