Ready Seal Natural Cedar Exterior Wood Stain and Sealer — Best Natural Finish

If you’re dealing with cedar, then you need specialist products designed to work with this material. If you maintain your cedar deck, it can give you joy for decades. However, cedar is a softer wood, and it requires weather treatment if outdoors in coastal areas and in regions of the United States where temperatures fluctuate widely between seasons.

Cedar is reasonably weather-resistant if you seal it with the right formula. Ready Seal natural exterior wood stain and sealer is an example of a specialist treatment product that’s suits any cedar deck or furniture. This formula enhances the natural color and beauty of the wood, highlighting the grain and texture of the cedar.

The oil-based stain has a semi-transparent finish, acting as a stain and sealer in one. It’s suitable to use Ready Seal on all types of woods, but it’s specially formulated to enhance the beauty of cedar. The stain and sealer penetrate deep into the cedar, protecting the wood from mold and fungus, as well as the sun’s harsh UV rays, rain, and snow.

You don’t need any primer when using Ready Seal. When applying, make sure you wait around 14-days between coats to let the color settle. Ready Seal is darkest when you first apply it to the deck. However, the color will lighten over the coming weeks.

Pros

• No back-brushing needed.
• Doesn’t lap, run, or streak.
• No need for wet-line application.
• Apply in any temperature range.
• User-friendly application.

Cons

Thompsons WaterSeal Advanced Natural Wood Protector — Best UV Resistance

Natural woods make the best decks. There’s nothing like the warm and natural feel that a wooden deck brings to your back yard. Regardless of the wood you use for your deck, it adds authenticity to your home, which increases the visual appeal of your yard and your home.

If you want to build or install a wooden deck in your home, you’re going to need to ensure that the vendor treats the deck before they deliver it or after installation. Make sure that you check on the craft of the contractor, as some like to cut corners in areas you can’t see, like the corners on the underside of your deck.

Exposing your natural wood deck to the weather can result in the growth of mold and other fungi that spread wood rot. As a result, your deck won’t last more than 5 to 10-years at most. Rot spreads quickly, and it can cost you a fortune in replacement and maintenance fees to save the deck.

Using Thompsons WaterSeal Advanced Natural Wood Protector is a fantastic option for resealing your deck every few years and keeping rot at bay. This unique formulation also features high UV-resistance, preventing your natural deck from warping under extreme heat conditions.

Rust-Oleum Coppercoat Wood Preservative — Best Anti-Fungal Sealer

If you live in a region of the United States that gets warm weather and rain most of the year, you probably battle with mold in and around your home. Mold loves the warm and wet weather. If you have a natural wood deck outside, then it’s at risk of getting infected with fungus, especially during the rainy season.

Mold spreads reasonably quickly, and any untreated wood will have exposure to developing rot. The last thing you need with your deck is to have to start ripping it up to replace rotting beams or floorboards. If you live in a hot and humid region of the United States, and you own a deck, you need to ensure you have the wood sealed every few years.
