Choosing the Right Stain

Clear sealant: Shows natural wood grain, requires reapplication every 1–2 years.
Semi-transparent: Adds color while showing wood grain, lasts 2–4 years.
Solid stain: Hides wood grain, most durable (4–6 years), best for weathered wood.
Always clean and dry the surface thoroughly before applying stain.
Apply when temperatures are 50–90°F and no rain is forecast for 24–48 hours.

🏗️ Pro Tip: New pressure-treated lumber needs to dry 3–6 months before staining — the preservative chemicals prevent adhesion until they cure. On weathered wood, clean and lightly sand before staining; rough surfaces absorb 25–30% more stain than smooth. Always apply a test patch in an inconspicuous spot before committing to a full coat.
