How often should I restain my deck?

Transparent stains need reapplication every 1-2 years, semi-transparent every 2-3 years, and solid stains every 4-6 years. The actual timeline depends on sun exposure, foot traffic, and climate. Perform a water bead test annually — if water soaks in instead of beading, it is time to restain.

Should I use oil-based or water-based exterior stain?

Oil-based stains penetrate deeper and are better for hardwoods and high-traffic decks. Water-based stains dry faster, have lower VOC, and clean up with soap and water. For pressure-treated softwood, either works well. For exotic hardwoods like Ipe, oil-based is strongly preferred.

Do I need to strip old stain before restaining?

For transparent and semi-transparent stains that have worn away naturally, cleaning and brightening is usually sufficient. Solid stains that are peeling or flaking must be stripped or sanded before recoating. Applying new stain over failing old stain will result in premature failure of the new coat.

Size Selection Guide

Coverage rates vary by stain type and wood porosity: transparent stains cover 150-300 sq ft per gallon, semi-transparent 200-400 sq ft, and solid stains 200-400 sq ft. For a typical 300 sq ft deck, plan on 1-2 gallons for a single coat of semi-transparent stain. Always buy an extra quart for touch-ups and maintenance.

Installation Tips

Apply stain to clean, dry wood with moisture content below 15%. Work in temperatures between 50-85°F and avoid direct sunlight during application. Apply with a stain pad or natural bristle brush for oil-based, synthetic brush or roller for water-based. Maintain a wet edge to avoid lap marks. Back-brush any pooling or drips within 10 minutes.

Common Mistakes to Avoid

Staining wood that is too wet or dirty, causing poor adhesion and blotchy results. Applying in direct sunlight causing the stain to dry too fast and not penetrate. Over-applying solid stains creating a thick film that peels. Skipping the wood brightener step after power washing. Not testing stain color on a scrap piece or hidden area first.

Budget Guide

Budget water-based stains cost $25-35 per gallon. Mid-range options run $35-50 per gallon. Premium oil-based stains range $45-65 per gallon. For a 300 sq ft deck, expect to spend $50-130 on stain alone. Add $30-50 for prep materials (cleaner, brightener, brushes, tape). Professional staining services run $2-5 per square foot.
