In terms of protection, this sealer offers good water resistance, UV resistance, and mildew and mold resistance, which are essential for exterior wood products. The natural cedar finish enhances the wood’s appearance while providing necessary protection against the elements. The drying time is reasonable, allowing users to get back to enjoying their outdoor spaces relatively quickly.

There are some considerations to keep in mind. The sealer is oil-based, which may not be suitable for everyone, especially those preferring eco-friendlier options. Moreover, it requires careful surface preparation; it should not be applied over painted or previously stained surfaces, as this could lead to adhesion issues. Also, the color may appear darker initially, taking up to 14 days to reach its final shade, which might not meet everyone's expectations right away.

The Ready Seal 545 Exterior Stain and Sealer is an oil-based product designed for wood surfaces, available in a 5-gallon container with a Burnt Hickory finish. Its ease of application is a key strength, requiring no primer or back brushing. It can be applied using a sprayer, roller, or brush without causing runs, laps, or streaks, making it user-friendly for those with little experience in applying sealers.

The product does not require diluting or thinning prior to application, saving time and effort. It is designed to blend itself without needing a wet-line application and can be applied under any temperature conditions, adding to its flexibility and convenience. This sealer is also noted for its coverage and the natural finish it provides over wood surfaces.

It takes approximately 14 days to reach its true color, so some patience is required. It's important not to apply it over painted or newly stained surfaces, as sealed surfaces will inhibit penetration. The product has good customer reviews, with a 4.5 out of 5-star rating, indicating general satisfaction among users. Those looking for a straightforward, easy-to-apply deck sealer that provides a natural look to wood surfaces may find this product suitable.

The Ready Seal 112 Natural Cedar Exterior Stain and Sealer is designed specifically for wood surfaces like decks and fences. It’s an oil-based sealer that provides good water resistance and protects your wood from UV damage, mold, and mildew. Once applied, it starts dark and gradually shows its true, natural cedar color over about two weeks. One big plus is that it requires no primer or back brushing, meaning the application is pretty straightforward and less messy than some other products.

You can apply it with a sprayer, roller, or brush, and it blends nicely without leaving streaks or runs. It’s also flexible with temperature, so you don’t have to worry about applying it only in certain weather conditions. In terms of durability, customers generally praise its lasting protection, although it’s important not to use it over painted or freshly stained wood since it seals surfaces tightly and won’t penetrate well then. Drying time is reasonable but keep in mind the color takes time to settle.

If you want a flat finish with reliable water and mildew resistance, and a natural look, this product suits well. For those needing a quicker color set or a sealer that works over old paint or stain, other options might be better. Its strong points are ease of use, good protection against weather and growth, and attractive natural coloring that develops over time.
