Ready Seal 512 Natural Cedar Sealer
Ready Seal 512 offers an all-in-one stain and sealer solution that requires no primer. It can be applied with sprayer, roller, or brush, and is designed to self-level, minimizing runs, laps, or streaks. It’s darkest upon initial application and will reach its true color in about 14 days, developing a deeper cedar hue as it cures. The product should not be applied over painted or newly stained surfaces, and properly sealed surfaces prevent deeper penetration for best results.
DEFY Extreme Crystal Clear Wood Stain and Sealer
DEFY Extreme Crystal Clear is a high-performance exterior wood coating that defends against graying and weathering while extending wood life. It uses zinc nano-particles to block UV rays, helping preserve natural cedar tones in all weather conditions. The coating is easy to apply via sprayer, brush, or roller, and cleanup is simple with mild soap and water. One gallon typically covers around 100–150 square feet depending on wood texture and porosity.
Thompson’s WaterSeal Transparent Cedar Stain
Thompson’s WaterSeal Transparent Waterproofing Wood Stain provides a clear finish that enhances cedar’s grain while offering water resistance. It emphasizes a light tint that maintains texture and is designed to resist UV fading, helping ensure color stays vibrant through seasons. The transparent approach is ideal when you want cedar’s natural look with basic protection against moisture intrusion.
SEAL-ONCE NANO+POLY Penetrating Sealer
SEAL-ONCE NANO+POLY is a penetrating, water-based polyurethane sealer that creates a water-resistant shield around wood. It’s low-VOC and odorless, suitable for decks, fences, log homes, and siding. The formula focuses on protecting wood from the elements by penetrating beyond the surface rather than just forming a topcoat. This can help maintain cedar’s natural appearance with a durable finish over time.
Olympic WaterGuard Clear Exterior Sealer
Olympic WaterGuard Clear Exterior Sealer is a ready-to-use water-based formula designed for new wood, pressure-treated wood, and weathered surfaces. It provides durable waterproofing protection and can cover up to about 350 square feet per gallon. The clear finish preserves cedar’s natural grain while offering straightforward maintenance and recoat opportunities as needed.
Buying Guide
Key purchase considerations for cedar fence sealers include:
- Clarity and appearance: Do you want a completely clear finish that preserves cedar’s natural look, or a very light tint that slightly enhances color?
- Penetration vs. topcoat: Penetrating sealers reduce surface wear and often require less maintenance, but some prefer a topcoat for a uniform color and shine.
- UV and moisture protection: Look for UV-blocking ingredients and moisture barriers to slow graying and water-related damage.
- VOC and odor: Low-VOC formulas are better for homes with sensitive occupants or enclosed spaces.
- Application method: Sprayer, roller, or brush compatibility affects labor and coverage rates. Consider recoat intervals and cure times.
- Wood condition: For cedar older or weathered wood, you may need surface preparation like cleaning or sanding before sealing.
- Maintenance requirements: Some finishes require more frequent reapplication; others offer longer-lasting protection with proper maintenance.
When choosing among these options, consider climate (humidity, UV exposure, and temperature swings), fence exposure (ground contact, shade, and wind), and maintenance preferences. For cedar, preserving the natural grain while providing durable moisture resistance often means balancing penetration depth with surface appearance. Always follow product directions for surface prep, primer requirements, and recoat schedules to maximize performance.
