Ready Seal Redwood Exterior Stain
Ready Seal 520 Exterior Stain and Sealer for Wood is designed to simplify outdoor finishing. It requires no primer and blends deep color as it dries, darkening on the first application and reaching its true shade after about 14 days.

Apply only to bare wood or properly prepared surfaces; applying over painted or newly stained surfaces can hinder penetration and performance.

Buying Guide
Color Depth Versus Grain Visibility
Solid-color stains deliver bold, uniform color that can hide grain and emphasize a clean look. Semi-transparent finishes prioritize grain visibility while adding color and protection. For redwood decks, consider whether you want the wood grain to be clearly visible or want a deeper, more uniform color. The Cabot Redwood Solid Color provides strong color, while DEFY Ultra offers a balance between color and grain retention.
Stain Type: Oil-Based Versus Water-Based
Oil-based stains tend to penetrate deeply and provide durability in high-traffic areas, often lasting longer between reapplications. Water-based stains typically dry faster and have lower odor, with easier cleanup. Olympic Maximum and DEFY Ultra illustrate this spectrum, with DEFY offering a versatile semi-transparent oil-based profile and Olympic delivering a durable, low-odor waterborne option in one product. Choose based on wood condition, maintenance plans, and indoor-outdoor air quality considerations.
Application Conditions and Drying
Weather and temperature influence application success. Some products specify temperature ranges and drying times (for instance, Olympic notes readiness to withstand rain after a short curing period). Planning around dry, mild days helps reduce brush marks and ensures even color. Consider whether you need a flexible schedule or faster project completion when selecting a stain.
Durability and Maintenance
Durability depends on pigment load, sealant properties, and UV protection. Solid-color stains often require less frequent upkeep but may necessitate more aggressive surface preparation when reapplying. Transparent or semi-transparent finishes emphasize grain and may require more frequent maintenance to keep color even. In professional use, products with UV defense and superior waterproofing typically offer longer intervals between reapplications.
Environmental Impact and VOCs
Low-VOC formulas are increasingly preferred for residential projects. Olympic’s product listing mentions low VOC, which may influence selection for indoor-adjacent or frequently used spaces. Check local regulations and personal sensitivities when evaluating products with solvent-based components or higher pigment loads. Always follow manufacturer recommendations for ventilation and safety during application.
Size, Coverage, and Surfaced Compatibility
Choosing the right size ensures fewer mid-project runs to purchase more product. Larger containers, like the Ready Seal five-gallon option, are suitable for big decks, while smaller gallons fit tighter budgets or single-project upgrades. Verify compatibility with your deck’s wood condition—new wood, aged surfaces, or previously stained boards may require different prep work and primer steps for optimal results.
