10 Best Deck Stains 2026 in the United States

Ready Seal 512 is an oil-based exterior wood stain and sealer designed for decks and other wood surfaces. One of its strongest points is its ease of application—it doesn’t require primer, thinning, or back brushing, and it blends itself smoothly without leaving streaks or runs. This makes it beginner-friendly and saves a lot of effort during application. The stain has moderate opacity, allowing about half an inch of penetration, which helps protect the wood while giving it a natural cedar color that darkens at first but settles to a natural tone within two weeks. It also offers UV resistance, which helps protect your deck from sun damage and fading over time. The product is mildew and mold resistant, which is important for outdoor use where moisture is a concern.

In terms of coverage, a 5-gallon pail covers roughly 625 square feet, suitable for larger projects. However, it is not recommended for use over painted or recently stained wood, so it works best on bare wood surfaces. While it claims to be durable, oil-based stains typically require reapplication every few years to maintain protection, so some maintenance should be expected. The flat finish will give a natural, less glossy look if you prefer that style. If you want a straightforward, reliable stain that’s easy to apply and offers good UV and mildew protection with a natural finish, this product is a solid choice. Just be aware it’s best for raw wood and not surfaces that already have paint or stain.

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.

The Cabot Australian Timber Oil Wood Stain and Protector in Jarrah Brown is a reliable option for those looking to enhance and protect their outdoor wood surfaces. This product boasts a unique 3-way oil protection system that ensures deep penetration and superior protection against extreme weather, which is crucial for maintaining outdoor decks, furniture, and railings. Its translucent finish highlights the natural beauty of wood, adding depth and a rich, natural color that stands out compared to other stains or deck paints. Available in four wood-toned colors, it provides versatility for different aesthetic preferences.

The oil-based formula ensures long-lasting durability and effective weather resistance, making it suitable for various exterior applications. Additionally, its resistance to mildew and mold helps in maintaining the wood's appearance over time. However, one downside is that oil-based stains like this often require more maintenance compared to water-based alternatives, such as regular reapplication and careful cleaning. Another consideration is the drying time, which might be longer than with other types of stains.

Despite these minor drawbacks, Cabot’s product is highly regarded for its performance and ease of application, making it a dependable choice for wood care enthusiasts looking to achieve both protection and aesthetic enhancement.
