10 Best Deck Stains 2025 in the United States

Ready Seal 120 Redwood is an oil-based exterior stain and sealer designed primarily for wood surfaces, making it a solid choice for deck owners looking for easy protection. Its oil base means it penetrates well into wood, helping with durability and water resistance. It offers good UV protection and is resistant to mold and mildew, which are important for keeping wood decks looking nice over time. The stain has medium opacity, providing decent color coverage without completely hiding the wood’s natural grain. The color starts darker and then settles into a true redwood shade in about two weeks.

One of its biggest strengths is the application process — it doesn’t require a primer, back brushing, or thinning, and it can be applied with a brush, roller, or sprayer without runs or streaks. This makes it beginner-friendly and saves time. It can also be applied in any temperature, which offers flexibility if you’re working around weather. However, Ready Seal cannot be applied over painted or newly stained surfaces, limiting its use on some decks without prep work.

The finish is flat, so it won’t give a shiny look, which some users may prefer or not depending on personal taste. Coverage is about 125 square feet per gallon, which is typical but not exceptional. For those seeking a stain that combines easy application with solid protection against sun and moisture, Ready Seal 120 Redwood is a suitable option. It performs best on clean, bare wood and delivers a natural, subtle appearance rather than a glossy coat.

Thompson’s WaterSeal Multi-Surface Waterproofer Stain is a versatile product designed to protect various exterior surfaces, including wood, concrete, and brick. This clear stain allows the natural texture of the wood to show through but will not highlight the grain, making it suitable for those who prefer a more subtle finish. One of its standout features is its waterproofing capability, which is essential for maintaining outdoor surfaces in good condition. Additionally, it offers UV protection, helping to prevent fading and discoloration over time. This makes it an excellent choice for areas exposed to constant sunlight.

The product is also easy to apply, requiring only one coat, which can save time and effort during application. However, users should ensure the surface is thoroughly cleaned beforehand for optimal results. On the downside, while the clear stain provides a natural look, it might not offer the vibrant color some users might desire from their deck stains. While the product claims to be mildew and mold resistant, users in very humid or damp environments might still need to monitor and maintain their surfaces regularly. Thompson’s WaterSeal Multi-Surface Waterproofer Stain is a reliable option for those seeking a durable and protective clear stain for their outdoor surfaces, but it may not be the best choice for those looking for a more colorful finish.

The DEFY Extreme Wood Stain and Sealer in Cedar Tone is a semi-transparent, water-based stain designed to enhance and protect exterior wood. One of its notable strengths is its advanced protection against UV rays, thanks to zinc nano-particles, which helps prevent graying and sun damage, making it a solid choice for long-term wood preservation. Additionally, it's rainproof and moisture-resistant, ensuring the wood stays protected against the elements. The stain also offers mildew and mold resistance, which is great for maintaining the wood's appearance and integrity over time.

Application is user-friendly, as you can use a sprayer, brush, or roller, and clean-up is straightforward with mild soap and water. Each gallon covers approximately 100-150 square feet with two coats, which might require more product for larger projects. The cedar tone color provides a warm and natural finish, appealing to those looking for a subtle enhancement rather than a completely opaque cover.

The semi-transparent nature means it won't completely hide imperfections in the wood, so it's best used on well-prepared surfaces. Made in the USA with a focus on quality, it's a reliable option for anyone looking to protect their decks, fences, or wood furniture from weathering.
