Enter your deck details to see material quantities, the recommended refinishing process, and a side-by-side comparison of DIY vs. professional costs.
DIY deck refinishing typically costs $0.50-$2.00 per square foot for materials (cleaner, brightener, stain/sealer). Professional refinishing runs $3-$8 per square foot including labor. A 300 sqft deck costs roughly $150-$600 DIY or $900-$2,400 professionally.
One gallon of deck stain covers approximately 150-200 square feet for the first coat and about 300 square feet for a second coat. A 300 sqft deck typically needs 2-3 gallons total for two coats.
It depends on the current condition. A dirty deck only needs power washing. Peeling stain requires chemical stripping or sanding. Gray/weathered wood benefits from power washing plus a wood brightener. Structural rot needs board replacement before any refinishing.
Cedar and exotic hardwoods like Ipe do best with high-quality penetrating oils that enhance the natural grain. Pressure-treated lumber works well with standard semi-transparent stains. Avoid film-forming products on cedar as they tend to peel.
Most decks need refinishing every 2-3 years with semi-transparent stain, or every 4-5 years with solid stain. Cedar and Ipe benefit from annual oiling in harsh climates. Use our stain calculator to plan gallons, prep, and finish cost.
