Coverage varies by wood type and stain, but plan for 200-300 sq ft per gallon for the first coat on new wood. Weathered or porous wood absorbs more stain, reducing coverage to 150-200 sq ft per gallon. For a typical 300 sq ft deck with two coats, you'll need 2-3 gallons. Always buy 10% extra for touch-ups and waste.
Oil-based stains typically need 24-48 hours between coats in ideal conditions. Water-based stains dry faster, usually 2-4 hours between coats. Temperature and humidity significantly affect drying times - high humidity or temperatures below 50°F can double drying time. The stain should feel dry to the touch and not tacky before applying the next coat.
Oil-based stains penetrate deeper into the wood, provide richer colors, and typically last longer on outdoor surfaces (3-5 years vs 2-3 years for water-based). They're ideal for decks, fences, and exterior projects. Water-based stains dry faster (2-4 hours vs 24-48 hours), have lower VOCs, clean up with soap and water, and work well for indoor furniture and projects where quick turnaround is important.
Generally no - stain penetrates into the wood rather than building up on the surface like paint. However, if the first coat raises the wood grain (common with water-based stains on bare wood), lightly sand with 220-320 grit sandpaper and wipe clean before the second coat. For best results, always sand bare wood before the first coat to ensure even absorption.
Softwoods like pine, fir, and spruce have uneven grain density that causes blotchy absorption. Apply a pre-stain wood conditioner before staining - this partially seals the wood for more even absorption. Apply conditioner, wait 5-15 minutes, then apply stain while still tacky. Gel stains also work well on softwoods because their thick consistency prevents over-absorption in softer areas.
Most stains allow light foot traffic after 24-48 hours and furniture placement after 72 hours. For oil-based stains, wait 7 days before placing heavy items or subjecting to heavy use. Water-based stains cure faster - typically 3-5 days for full cure. Check the manufacturer's specific recommendations, as formulations vary. Avoid getting the deck wet during the curing period.
