10 Best Concrete Sealer 2026 in the United States

The Armor SX5000 WB Natural-Look Penetrating Water-Based Silane Siloxane Concrete Sealer is a solid choice for anyone looking to protect various surfaces like concrete, brick, or natural stone. One of its standout features is its ability to reduce water absorption by up to 95%, which means it provides excellent protection against water damage, cracking, and staining. This sealer is designed to last between 7 to 10 years, so it offers long-term value. Additionally, it's a water-based product with zero VOCs, making it user-friendly and eco-friendly—clean-up is as simple as using soap and water.

Versatility is another strong point; whether your surface is stamped concrete, masonry, or brick, this sealer can handle it. Users appreciate that it won’t alter the appearance of their surfaces, maintaining the natural look and feel.

However, there are a few considerations to keep in mind. Although the application is straightforward with a pump sprayer, some users may find it challenging if they are not experienced with sealers. The recommended coverage of 175-225 square feet per gallon may require planning for larger projects, especially since it comes in a 5-gallon pail. While the sealer's long-lasting properties are a plus, the initial investment may seem high for occasional users.

The Armor SX5000 WB is well-suited for homeowners or contractors seeking reliable, long-lasting protection for various masonry surfaces. Its easy application and minimal odor make it particularly appealing for residential use, but those new to sealers might need to do a little extra preparation to achieve the best results.

The Armor AR500 High Gloss Wet Look Concrete Sealer is a professional-grade, solvent-based acrylic sealer designed to enhance and protect exterior concrete and pavers. It provides a high gloss, wet look finish that dramatically enhances the color and appearance of your surfaces, making them look attractive. One notable strength is its long-lasting protection against various forms of damage such as surface abrasion, UV rays, and water absorption, which is useful for both residential and commercial applications.

The sealer is easy to apply using a roller or sprayer and is self-priming, which simplifies the maintenance process. It covers a substantial area, with one gallon covering up to 225 square feet, and is versatile enough to be used on different concrete surfaces like driveways, walkways, and patios.

However, one potential drawback is its high VOC content (700 VOC), which may not be suitable for all states due to regulatory restrictions on emissions. This version is best suited for areas without stringent VOC regulations. The product is also quite heavy at 42 pounds, which might make it challenging to handle for some users. Despite these drawbacks, the Armor AR500 stands out for its durability, ease of use, and impressive finish, making it a strong choice for enhancing and protecting exterior concrete surfaces.

Siloxa-Tek 8500 Ultra Concentrate is a high-quality penetrating concrete sealer designed to protect surfaces like concrete, brick, masonry, and pavers without altering their natural look. It uses a silane/siloxane formula, which means it soaks deep into the material rather than sitting on top, providing long-lasting water and salt resistance. This product is water-based and has low VOC content, making it a safer choice for indoor or outdoor use with less harmful fumes. It’s also breathable and won’t peel or flake, preserving the surface texture and preventing slippery finishes.

One of its standout features is durability: it’s approved by the Department of Transportation and can protect against damage from freeze-thaw cycles, deicing salts, and wind-driven rain. The sealer boasts a higher concentration of active ingredients than many competitors, promising protection that can last up to 10 years if applied properly, especially on vertical surfaces. Application is flexible—you can use a sprayer, roller, or brush, and it covers about 250 square feet per gallon per coat, which is efficient considering the concentrated formula.

Because it is a penetrating sealer, it won’t add a glossy or shiny finish if that is something you desire. This product is best for those looking to maintain a natural look while securing their concrete or masonry against moisture and environmental damage, rather than for those wanting a decorative surface change. Siloxa-Tek 8500 Ultra Concentrate is an excellent choice for anyone needing a durable, clear, and breathable concrete sealer that offers strong protection with minimal impact on appearance.
