10 Best Polyurethane Concrete Sealers 2025 in the United States

The Armor AR350 Low Gloss Wet Look Concrete Sealer is a professional-grade option designed to protect and enhance exterior concrete and pavers. It uses a solvent-based acrylic formula that offers a durable, low gloss finish with a wet look that darkens surfaces, which many users find visually appealing. It stands out for its strong durability, resisting damage from foot and vehicle traffic, abrasion, road salts, and various weather conditions including UV rays, which helps prevent yellowing over time. This makes it suitable for driveways, patios, pool decks, and more.

The sealer is easy to apply with a roller or sprayer and is self-priming, so maintenance and resealing are straightforward tasks. Coverage is decent at around 175-225 square feet per gallon. However, since it's solvent-based and has a VOC level of 700, it may have stronger fumes compared to water-based options and might require good ventilation during application. While it offers chemical resistance typical for acrylic sealers, it may not hold up as well against harsh chemicals as specialized polyurethane products.

The product also comes in formulations suitable for different state VOC regulations, which is helpful if local rules apply. If you're looking for a sealer that delivers lasting protection with enhanced color and a subtle wet look without a high shine, the Armor AR350 fits well, especially for outdoor residential or commercial concrete surfaces. Just be prepared for solvent-based application precautions.

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.

Siloxa-Tek 8500 Ultra Concentrate is a high-quality, water-based concrete sealer designed to protect surfaces like concrete, pavers, brick, and stone from water and salt damage. Its main strength lies in durability, thanks to a powerful silane/siloxane formula that penetrates deeply without changing the look or feel of the surface. Unlike some sealers, it won’t peel or flake because it doesn’t form a film on top, which means it’s breathable and lets moisture escape, reducing issues like cracking and spalling caused by freeze-thaw cycles.

This product is especially good at resisting harsh chemicals like deicing salts, making it a solid choice for outdoor areas exposed to winter weather. Its UV stability is excellent, so it won’t break down or yellow under sunlight, keeping protected surfaces intact for years. The sealer leaves no glossy finish, maintaining a natural, non-slick surface which is safer for patios and walkways. Application is straightforward and flexible—you can use a sprayer, roller, or brush, covering about 250 square feet per gallon per coat. Because it’s highly concentrated, one gallon can make up to five gallons of ready-to-use sealer, which offers good value.

To get the best long-term results, especially on vertical surfaces, you might need a certified applicator, which could add to installation costs. Also, since it’s a penetrating sealer, it doesn’t provide a shiny or decorative finish if that’s what you’re looking for. In essence, Siloxa-Tek 8500 is ideal for those wanting durable, invisible protection against water, salt, and UV damage with minimal maintenance, but not for users seeking a glossy or colored result.
