DIY vs. Call a Pro
Power wash the deck and let it dry 24-48 hours. Apply deck cleaner to remove gray fibers if needed. Use a pump sprayer or stain pad to apply stain, working in the direction of the wood grain. Apply two thin coats rather than one thick coat.
Call a professional when:
Hire a professional for large decks, decks that need significant repair before staining, or if previous stain needs chemical stripping. Pros have commercial-grade equipment for faster, more even application.
