10 Best Brick Water Sealer 2025 in the United States

The Armor SX5000 WB is a high-quality, water-based sealer designed for protecting a range of surfaces such as concrete, brick, and natural stone. One of its standout features is its ability to significantly reduce water absorption by up to 95%, which helps prevent damage from cracks and stains over time. The professional-grade Silane-Siloxane formula is particularly beneficial for both interior and exterior applications, providing a durable barrier that lasts between 7 to 10 years. Furthermore, it maintains the original look and feel of the surfaces it protects, which is a major plus for homeowners looking to preserve their aesthetics.

Ease of application is another strength; it's ready to use, allowing for straightforward application with a pump sprayer, and clean-up is hassle-free thanks to its water-based formula with zero VOCs and no odor. This makes it suitable for DIY enthusiasts who may not have a lot of experience with sealers.

There are a few considerations to keep in mind. While it provides solid protection, the initial preparation of the surfaces is crucial for the best results, requiring proper cleaning to ensure effectiveness. Additionally, while the 5-gallon size is great for larger projects, it may be more than what some users need, which could lead to waste if they only have a small area to treat.

The McKinnon Concrete Sealer is a water-based acrylic sealer that offers a high gloss wet look for a variety of surfaces such as concrete, brick, natural stone, limestone, rock, cement, flagstone, stucco, and pool decks. One of its strong points is its durability, as it is designed not to peel or crack and provides protection for up to 5 years, which is impressive in this category.

The ease of application is another advantage, with the sealer drying clear within 8 hours, making it user-friendly for both professionals and DIY enthusiasts. Its versatile use across different substrates makes it a flexible choice for many outdoor and indoor projects.

The finish provides a high gloss look, which is great for enhancing the appearance of surfaces but might not be suitable for those preferring a more natural matte finish. The McKinnon Concrete Sealer remains a solid choice for those looking for a durable, versatile, and easy-to-apply sealer to revive and protect their surfaces.

The Siloxa-Tek 8500 Ultra Concentrate is a penetrating concrete sealer that is a strong contender in the brick-water-sealer category. As a water-based silane/siloxane solution, it provides effective water and salt repellency without altering the appearance of your surfaces, making it an attractive choice for those who want to maintain the natural look of their concrete, brick, masonry, or pavers. Its non-film-forming characteristics ensure that it won't peel, flake, or delaminate over time, adding to its durability.

The product's durability is further enhanced by its resistance to surface damage from chlorides and deicing salts, an essential feature for environments exposed to freeze-thaw cycles. Its UV stability means it won't degrade under sunlight, making it reliable for outdoor applications. The high concentration of active ingredients promises long-lasting protection, requiring reapplication only every few years, depending on usage and exposure.

Ease of application is another strength; it can be applied using a sprayer, roller, or brush, making it accessible for both DIY projects and professional use. It covers up to 250 square feet per gallon, providing a good balance between coverage and cost-effectiveness. The breathable nature of this sealer prevents moisture build-up underneath the surface, helping to preserve the structural integrity of the treated material. Potential users should consider that while it offers excellent protection against water and salts, its performance in other specific scenarios, like oil resistance, isn't highlighted. Additionally, while it claims a non-slick surface, care must be taken during application to maintain safety, particularly in high-traffic areas. The Siloxa-Tek 8500 is well-suited for residential and commercial projects needing a robust, long-lasting sealer that keeps surfaces looking natural while providing effective protection from the elements.
