10 Best Polyurethane Concrete Sealers 2025 in the United States

The Siloxa-Tek 8500 Ready to Use Concrete Sealer from Ghostshield is a versatile sealer ideal for both commercial and residential use. Its primary strengths lie in its durability and chemical resistance. With 6x higher active ingredients than other water-based sealers, it provides long-lasting protection against water and salt damage. The product is D.O.T approved, which speaks to its robust performance, particularly in resisting surface damage from chlorides and deicing salts.

Its UV stability ensures that it won't break down or fade under direct sunlight, making it suitable for outdoor applications without worrying about yellowing or peeling over time. Additionally, it offers excellent protection against freeze-thaw cycles, reducing the risk of cracking, spalling, and pitting on treated surfaces. Application is straightforward and flexible, as it can be applied with a sprayer, roller, or brush, covering up to 250 square feet per gallon per coat.

Users also appreciate that it dries clear, maintaining the natural appearance of the surfaces it is applied to without adding any sheen or gloss, which is a critical consideration for those seeking a natural look. However, one potential drawback is the need for a certified applicator to achieve the maximum longevity of up to 10 years, which may not be practical for everyone. Another minor inconvenience could be the weight of the product, at 10 pounds per gallon, potentially making application slightly labor-intensive. The Siloxa-Tek 8500 is particularly beneficial for those looking to protect driveways, garages, basements, patios, and pool decks from water and salt damage while maintaining a natural, non-slick surface.

Moreover, it aids in proper curing of new concrete and meets ASTM C-1315 and C-309 standards, ensuring quality performance. Application is convenient with a roller or sprayer, and its low VOC and low odor formulation make it suitable for use in all 50 states, including indoor and outdoor settings.

The Armor AR350 Low Gloss Wet Look Concrete Sealer offers a professional-grade solution for enhancing and protecting exterior concrete and paver surfaces. Its key strength lies in its ability to provide a dramatic color enhancement while delivering a durable, long-lasting, and non-yellowing finish. This makes it a suitable choice for both residential and commercial applications, ensuring surfaces are safeguarded against abrasion, traffic, road salts, UV rays, water, snow, and other elements.

This sealer's chemical resistance and UV stability contribute to its longevity, making it a reliable option for high-traffic areas like driveways, walkways, and patios. The product's low gloss level ensures a subtle, attractive wet look without excessive shininess, catering to those preferring a more understated finish. Ease of application is another highlight, as the Armor AR350 is ready to use and can be applied with a roller or sprayer, covering up to 225 square feet per gallon.

Its self-priming nature simplifies maintenance, allowing for easy reapplication when needed. However, potential users should be aware that being solvent-based, it may have a strong odor during application and requires proper ventilation. Additionally, its effectiveness on previously unsealed or solvent-sealed surfaces limits its versatility compared to some water-based alternatives. Despite these minor drawbacks, the Armor AR350 stands out as a robust and effective concrete sealer, particularly for those seeking long-term protection and color enhancement for their outdoor surfaces.
