Transparent Stains

Transparent stains highlight natural beauty of exterior wood while adding protection that resists UV, moisture, mildew, and foot traffic. Designed for decks, fences, siding, pergolas, railings, and outdoor furniture, they let grain and color show through for a warm, natural-looking finish.

Choose from water-based for fast drying, low odor, and simple soap-and-water cleanup; oil-based for deep penetration, rich appearance, and longer open time; or hybrid alkyd-modified waterborne formulas that balance durability and low VOC. Tints range from clear to lightly toned; more pigment means stronger UV defense, while crystal-clear options offer the least sun resistance.

Preparation drives results: clean, degrease, and brighten aged wood to remove gray oxidation and mill glaze. Sand decks to 60–80 grit and furniture to 100–120; dry to <15% moisture. Stir well; do not thin unless the label allows. Apply in shade between 50–90°F, avoiding hot surfaces. Use a stain pad, brush, roller with back-brushing, or a pump/airless sprayer and back-brush. Work two–three boards at a time, keeping a wet edge to prevent lap marks. One saturated coat is typical; avoid film build. Wipe excess after 15–30 minutes on dense species.

Expect coverage of 150–350 sq ft per gallon depending on porosity. Dry to touch in 1–4 hours; light use in 24 hours; full cure by 72 hours, longer in cool or humid conditions. Maintain by washing annually and reapplying every 12–36 months on horizontal surfaces, 24–48 months on vertical.

Selection tips: look for UV blockers for full sun, mildewcides for humid sites, low-VOC formulas for local compliance, anti-slip additives for stairs, and marine-grade options for docks. Suitable woods include cedar, redwood, pressure-treated pine, ipe, and other hardwoods (test absorption). Not for film-finished or previously painted surfaces without stripping.
