Reseal wood deck

Why It Matters

UV and moisture turn unsealed wood gray, cup, and crack within a few seasons. Sealing extends deck life and prevents rot.

Tools

• Broom or leaf blower
• Garden hose
• Roller with extension pole
• Pump sprayer
• Stiff-bristle brush

Materials

• Deck cleaner
• Deck sealer or stain

How to Do It

1. Sweep the deck thoroughly to remove leaves, dirt, and debris.
2. Apply deck cleaner according to its label, scrubbing as needed to remove mildew, graying, and old residue.
3. Rinse the deck completely with a garden hose and let it dry for 24-48 hours. The wood must be fully dry before sealing.
4. Stir the sealer or stain, then load your roller or pump sprayer.
5. Apply sealer or stain in the direction of the wood grain, working in manageable sections to maintain a wet edge and avoid lap marks.
6. Let the sealer cure fully before returning furniture or foot traffic to the deck, following the product's recommended drying time.
