Flood Easy Seal 1 gal. Natural Cedar
Product overview: This premium oil-based wood finish provides a one-coat application designed for cedar surfaces. Fortified with PENETROL, it penetrates deep into wood fibers for a flawless finish that resists runs, laps, and back-brushing. The natural cedar tone helps preserve cedar’s warm hue while delivering robust protection against moisture and UV exposure. Best suited for decks, siding, and outdoor furniture where a single, durable coat is preferred.
Flood Easy Seal 1 gal. Natural Cedar — Highlights
- One-coat application simplifies projects with limited time
- Penetrating formula reduces surface layer buildup
- Premium oil-based finish resists moisture and sun damage
Flood FLD520 Cedar CWF-UV Exterior Clear
Product overview: This oil-based finish enhances cedar with a clear tone that minimally alters color while highlighting natural grain. The CWF-UV formula offers moisture resistance and sun protection, helping cedar surfaces stay visually appealing longer. It’s ideal for newer, less weathered wood where the goal is to preserve native beauty with subtle protection.
Application considerations
Oil-based finishes like Flood FLD520 and Flood Easy Seal penetrate wood deeply, offering strong protection for cedar subjected to sun and rain. They tend to darken cedar slightly and require longer cure times in humid environments. For large horizontal surfaces such as decks, consider the film-forming properties to prevent wear from foot traffic.
General Finishes Exterior 450
Product overview: Exterior 450 is a premium water-based stain designed for outdoor vertical surfaces like fences and siding. It includes UV absorbers to protect film integrity while allowing wood grain to show through. This finish is easy to apply with brushes, rollers, or sprayers and cleanup is simple with soap and water. Note that it is not recommended for large horizontal decks, where deeper protection may be needed.
DEFY Ultra Semi-Transparent Cedar
Product overview: DEFY Ultra combines stain and sealer in one, delivering a semi-transparent finish that preserves cedar’s grain while adding color and protection. It can be applied as a single coat or two coats for deeper color and a satin sheen. This versatile option is suitable for decks, fences, porches, and pergolas, offering long-lasting performance against the elements.
PPG ProLuxe Premium Deck Wood Finish, 1 Gallon, 077 Cedar
Product overview: The ProLuxe line emphasizes wood protection with translucent Cedar tones and UV absorbers. It’s designed for outdoor deck surfaces, providing color while maintaining grain visibility. The high-solids formulation helps resist environmental wear and provides a durable surface that guards against moisture and sunlight exposure.
PPG ProLuxe Premium Deck Wood Finish Cedar (Alternate)
Product overview: An alternative ProLuxe cedar option, this high-solids oil-based finish emphasizes grain and provides long-lasting protection for outdoor wood projects. Suitable for decks and outdoor structures where cedar’s natural beauty is a priority and UV resistance is a concern.
HOPE’S Tung Oil
Product overview: 100% pure tung oil offers a natural, hand-rubbed finish that penetrates wood rather than forming a thick film on the surface. While it provides a natural look and antimicrobial properties, it requires periodic reapplication for outdoor cedar exposure to moisture and sun. It is also valued for food-safe applications on certain outdoor furniture components when used appropriately.
Buying Guide: Key Considerations For Outdoor Cedar Finishes
- Penetration vs. film-forming: Penetrating oils (like tung oil and some Flood products) emphasize depth in the wood, while film-forming finishes (many polyurethane- and varnish-based products) provide a protective layer. For cedar, penetration helps maintain breathability and reduces peeling on softwoods, but film options can offer more durable surface protection on high-traffic decks.
- Oil-based vs. water-based: Oil-based finishes generally deepen color and enhance grain with strong moisture resistance, but may have longer cure times and odor. Water-based finishes often dry faster, clean up with soap and water, and emit less odor, though some colors may appear lighter or less saturated.
- UV protection: Finishes with UV absorbers help protect cedar from graying and color fading. UV stability is crucial for sun-heavy regions and horizontal surfaces that receive direct sunlight.
- Surface type and project scope: Vertical surfaces (fences, siding) tolerate water-based stains well, while decks and porches benefit from deeper protection offered by oil-based formulas. For older, weathered cedar, choose products designed to penetrate and rebuild surface resistance.
- Reapplication and maintenance: Consider maintenance cycles. Some finishes require re-coating every 1–3 years, while others—especially penetrating oils—require more frequent renewed applications depending on exposure and cedar condition.
- Color and grain visibility: Semi-transparent and clear finishes preserve natural cedar grain, while lightly tinted stains enhance color and provide additional depth. For outdoor furniture and decorative cedar features, color choice should balance aesthetics with protection needs.
- Ease of use and cleanup: Water-based products often offer simpler cleanup and cleanup with soap and water, while oil-based options may require mineral spirits. Brushing versus spraying compatibility can influence project choice and equipment needs.
In sum, the right finish for outdoor cedar depends on the surface type, climate, and maintenance willingness. Oil-based options typically deliver stronger protection and richer color for decks and siding, while water-based products suit vertical surfaces and quick projects. For a natural look with durable protection, consider semi-transparent or penetrating finishes that balance grain visibility with moisture resistance.
