10 Best Wood Fence Sealers 2025 in the United States

The Ready Seal 512 5-Gallon Pail Natural Cedar Exterior Stain and Sealer is an oil-based product designed specifically for wood surfaces. It's highly praised for being easy to apply as it requires no primer, back brushing, or thinning. It can be applied using a sprayer, roller, or brush in any temperature, and it blends itself without leaving runs, laps, or streaks, making the application 'goof proof.' This product is particularly beneficial due to its UV resistance, which helps protect the wood from sun damage.

However, it's important to note that it should not be applied over painted or newly stained surfaces, as sealed surfaces inhibit penetration. The product's durability is suggested by its long-lasting finish and protection, though individual results might vary. The biggest drawback might be the initial dark appearance right after application, but it reaches its true color in about 14 days.

This sealer is well-suited for users looking for an easy-to-apply, durable, and UV-protecting solution for wood fences or other exterior wood surfaces.
