10 Best Deck Stains 2025 in the United States

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.

The Ready Seal Stain & Sealer for Wood in Redwood offers a convenient all-in-one solution for your exterior wood needs. Its easy application process stands out, as it requires no priming, thinning, or back-brushing, making it user-friendly even for those with minimal staining experience. The mineral oil-based formula ensures excellent penetration and long-lasting protection, enhancing the natural beauty of wood while providing a durable, waterproof barrier against the elements.

Its UV resistance feature is particularly beneficial, as it helps prevent fading and sun damage, ensuring your wood surfaces maintain their vibrant look over time. Additionally, the self-blending formula guarantees an even, streak-free finish without lap marks, which can often be a challenge with other stains. However, it’s important to note that while it offers strong UV protection, the product information does not specifically highlight mildew and mold resistance, which might be a consideration depending on your climate and wood exposure conditions.

The coverage of 125-150 square feet per gallon is decent, but larger projects might require multiple gallons, potentially increasing cost. The rich Redwood color is aesthetically pleasing and versatile for various outdoor projects like decks, fences, and furniture. The Ready Seal Stain & Sealer is a reliable choice for exterior wood protection, though if mildew and mold resistance are crucial, additional preventive measures may be needed.
