Penofin Transparent Matte Sierra Oil-Based Penetrating Wood Stain is a purpose-built solution for outdoor wood that wants to breathe life back into its natural grain. This 1-gallon formula penetrates deeply into the wood fibers, delivering lasting protection without creating a bulky film. The result is a warm Sierra brown with a transparent matte finish that highlights texture while guarding against sun, moisture, and the elements.
Why this stain stands apart
-
Deep Oil-Based Penetration: Unlike surface coatings, this stain soaks into the wood to protect from within, helping reduce cracking, checking, and surface wear over time.
-
Transparent Matte Finish: Preserves the natural beauty and grain of the wood while delivering a low-sheen, sophisticated look that ages gracefully with exposure.
-
Outdoor-Grade UV Protection: Specifically formulated to resist sunlight, helping to slow color fade on decks, fences, siding, pergolas, and outdoor furniture.
-
Water Repellent and Weather-Resistant
-
1 Gal Coverage: Typically covers about 300–400 sq ft per gallon, depending on porosity and texture of the wood.
-
Application Versatility: Apply with a brush, stain pad, or a plastic pump sprayer for efficient, even coating on large or intricate surfaces.
-
Color and Tinting: Sierra brings a rich brown tone while remaining tint-free, so you get consistent color without altering the wood’s character.
-
Recoat Time: Ready for a second coat after 4 hours, helping you complete projects faster without long downtime.
-
VOC compliant: Formulated with a 250 VOC level to balance performance and environmental considerations.
-
Sealer Status: Not a separate sealer; it’s a penetrating stain designed to work with the wood’s own pores for natural protection.
Ideal uses and practical applications
Perfect for outdoor projects where you want to maintain wood’s texture and warm tones:
- Decks and porches that endure sun and rain
- Fence panels and railings that benefit from UV resistance
- Exterior siding and trim that need a breathable, low-sheen finish
- Pergolas, garden furniture, and outdoor structures that benefit from a natural look
How to get the best results
-
Surface prep: Ensure wood is clean, dry, and free of old finishes that could impede penetration. Slightly sand rough spots for uniform staining.
-
Test area: Apply a small sample on a hidden patch to confirm color and penetration before full coverage.
-
Apply: Use a brush, stain pad, or plastic pump sprayer to apply a thin, even coat along the grain. Avoid puddles; aim for a consistent film.
-
Recoat: After the recommended 4-hour touch-dry period, assess the surface and apply a second coat if deeper color or enhanced protection is desired.
-
Maintenance: Outdoor elements will weather over time. Plan for reapplication as needed to maintain color and protection.
-
Cleanup: Clean tools with mineral spirits or as recommended for oil-based finishes.
