One of its standout features is that it requires no primer and can be applied using a sprayer, roller, or brush without the need for back brushing. This makes it quite user-friendly as it will not leave runs, laps, or streaks, and it can be applied in any temperature range without needing diluting or thinning.

The sealer is 'goof proof,' meaning it self-blends and simplifies the application process, which is great for beginners or those looking for a hassle-free project. It is important to note its darkest appearance when first applied, gradually reaching its true color in about 14 days. The product offers good UV protection and water resistance, helping to prevent wood from fading and damage. It also has mildew and mold resistance, which is essential for exterior wood in various climates.

On the downside, it cannot be applied over painted or newly stained surfaces, which might limit its use in some scenarios. Additionally, some users may find the flat finish less appealing compared to a glossy finish. At 5 gallons, it provides a significant quantity, making it suitable for larger projects. Its ranking in the tools and home improvement category and specific feature set make it a solid choice for those looking to protect and enhance exterior wood surfaces with minimal fuss.

It offers good water resistance and some mildew and UV protection, typical for oil-based sealers, helping to preserve the wood’s look and durability. Coverage is about 125 square feet per gallon, which is fairly standard. However, it should not be used over painted or freshly stained surfaces, as it won’t penetrate properly. One downside is that it’s not available in some states like California due to recycling fees.

Additionally, its semi-transparent finish allows the natural beauty of the wood to shine through while providing a protective layer against UV rays, mold, and mildew, enhancing its durability and longevity. This comprehensive protection makes it suitable for various outdoor wood surfaces like siding, decks, and fences.

However, despite its many advantages, the product does have some drawbacks. The clear color might not be ideal for those looking to alter or enhance the color of their wood, as it provides a natural look with minimal color change. Furthermore, although it is rainproof and offers good water resistance, its oil-based nature may require more diligent maintenance over time compared to water-based alternatives. Additionally, at 37 pounds, the 5-gallon container is quite heavy, which might be cumbersome for some users to handle. Despite these minor inconveniences, the Ready Seal 500 is a strong option for those looking for a reliable and easy-to-apply wood stain and sealer that offers robust protection and a natural finish.
