Ready Seal 520 Redwood Stain & Sealer
Ready Seal 520 is a 5-gallon exterior stain and sealer designed for redwood. It requires no primer and darkens upon initial application, with the true color maturing over about two weeks. Do not apply over painted or newly stained surfaces, as sealed layers can impede penetration. It accepts application by spray, roller, or brush, and does not require back brushing, reducing runs and streaks on large fence projects. The formula emphasizes barrier performance while preserving a natural look, making it a practical choice for expansive Redwood fencing installations.
- No primer required; smooth, even coverage from the first coat
- Color deepens initially and settles over roughly 14 days
- Sprayer, roller, or brush compatible; no back brushing needed

For best results, apply in moderate temperatures and avoid very thick coats. Plan reapplication according to local weather exposure to maintain color and protection over time.

Buying Guide
Choosing the right Redwood fence sealer involves balancing color depth, protection level, and maintenance needs. Consider these key purchase factors to align a product with your project and climate:
- Wood condition and substrate: Start with well-prepared, clean wood. Existing finishes may affect penetration and color evenness.
- Translucency versus color: Semi-transparent sealers preserve the wood grain, while solid or deeper stains yield richer color but less grain visibility. Your aesthetic preference and visibility of the grain will guide this choice.
- One-step versus multi-step: Some products combine stain and sealant in one coat, while others are either stain-only or sealant-only or require priming. For quick projects, a one-step option can save time, but two-step systems may offer stronger protection in harsh climates.
- UV protection and moisture resistance: Greater UV shielding helps prevent graying, color fade, and moisture-related damage. UV-blocking additives vary by brand and formulation.
- Application method and climate: If you work in cooler or variable weather, look for products labeled as weather-ready at lower temperatures. Sprayer, roller, and brush compatibility also affects prep time and labor costs.
- Drying and recoat times: Drying time and recoat windows influence project duration and weather risk. Some products allow rapid recoat after a short waiting period, while others require longer cures.
- Coverage and gallon size: Evaluate the expected area to seal. Larger jobs may benefit from 5-gallon containers, while smaller decks or fences can be completed with 1-gallon options.
- VOC and environmental considerations: Low-VOC formulas reduce air emissions and are preferable for homes with indoor exposure near treated wood during curing.
- Maintenance intervals: Durability varies with climate and wood exposure. Be prepared for reapplications every 2–5 years depending on sun, rain, and foot traffic.
- Brand and warranty: Reputable brands with proven performance in exterior wood protect against moisture and color loss, and some offer warranties for added peace of mind.
In summary, if you want a straightforward, one-step solution with strong UV protection, consider Ready Seal or Olympic Maximum. For maximum grain visibility with sturdy weatherproofing, look to Storm System Protector or DEFY Extreme. If you prefer a single product that combines color and sealant with reliable long-term protection, DEFY Essential or Ultra offerings may also suit lighter redwood applications. Always perform a small test on scrap wood to confirm color and penetration before full-scale application.
