The Armor SX5000 WB is a professional-grade water-based silane siloxane sealer designed for use on a variety of surfaces including concrete, brick, pavers, and natural stone. One of its standout features is its ability to reduce water absorption by up to 95%, thereby offering long-lasting protection against water damage, cracking, spalling, and staining. This makes it particularly beneficial for those looking to maintain and protect outdoor surfaces exposed to the elements.

Additionally, it does not alter the appearance, color, or feel of the substrate, preserving the natural look of your surfaces. The sealer is ready to use and can be applied easily with a pump sprayer, covering an area of up to 175-225 square feet per gallon. Maintenance is straightforward, as it works below the surface without forming a film, making reapplication simple. It is also water-based, meaning it has 0 VOC content and no odor, which is a plus for eco-conscious users and easy cleanup with soap and water.

However, the product's weight (44 pounds) might be cumbersome for some users, and its high initial cost may be a consideration for those on a budget. Additionally, it is essential to apply it to a properly cleaned and prepped surface to achieve the best results. This product is ideal for those who need a durable, long-lasting sealer that is easy to apply and maintain, without changing the appearance of their surfaces.

As a low VOC product, it is environmentally friendly and does not produce harmful fumes, making it suitable for both indoor and outdoor use.

The user-friendly application process, which can be done using a sprayer, roller, or brush, makes it accessible for DIY enthusiasts and professionals alike. The coverage is effective, allowing up to 250 square feet per gallon, although it requires mixing to create a total of 5 gallons from the concentrate provided. A standout feature is its durability, with the potential to last up to 10 years on vertical surfaces when applied by certified professionals, making it an attractive option for long-term projects.

While it is a penetrating sealer that does not alter the surface's profile, the initial cost might be higher compared to some alternatives. Given its high actives formula designed for UV stability and deep penetration, it is particularly beneficial in harsh weather conditions prone to freeze-thaw cycles. This sealer is best suited for those looking for a high-performance solution for both residential and commercial applications, especially in areas exposed to deicing salts and moisture intrusion.

It creates a low gloss finish that doesn't yellow over time, maintaining the aesthetic appeal of your surfaces for years. The sealer is versatile and can be used on a variety of exterior surfaces, including driveways, patios, and pool decks. One of its significant advantages is ease of use; it is ready to apply with a roller or sprayer and is self-priming, which simplifies the maintenance process.

However, it is important to note that this product has a high VOC content (700 VOC), which might not be suitable in areas with strict environmental regulations. Additionally, because it is solvent-based, it requires proper ventilation during application to ensure safety. Users should also be aware of its relatively heavy weight (42 pounds) and the need for proper surface preparation to achieve the best results. This sealer is ideally suited for those looking to maximize the longevity and visual appeal of their exterior concrete surfaces while being prepared for the additional considerations of handling and application.
