10 Best Concrete Sealer 2025 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 Rainguard Water Sealers Concrete Sealer is a penetrating silane/siloxane-based product designed to protect concrete surfaces from water, salt, stains, and weather damage. It creates a natural, no-gloss finish that keeps the concrete looking its best without altering its appearance. This sealer is water-based and low in VOCs, making it safer for use around people, pets, and plants.

It offers good durability with up to 5 years of protection, which is solid for many outdoor applications. Application involves using a pump sprayer to apply two flood coats, which might require some effort, but the sealer dries within about an hour at room temperature. Coverage is around 200 square feet per gallon, depending on how porous the surface is, so the 5-gallon pail is suitable for medium to large projects like driveways, patios, and pool decks.

One of the strengths is its ability to create an invisible, filmless barrier that repels water and helps prevent cracks from freeze-thaw cycles. This product is a dependable choice for anyone wanting a natural-looking, long-lasting concrete waterproofer that is easy to apply and environmentally friendly.

The Armor AR350 Low Gloss Wet Look Concrete Sealer is a solvent-based acrylic sealer designed mainly for exterior concrete and pavers. It provides a low gloss, wet look finish that significantly enhances the color of your surfaces, making them appear darker and more vibrant, much like when they're wet. This sealer is durable and protects well against everyday wear, including foot and vehicle traffic, UV damage, and weather effects like snow or road salts, which makes it a solid choice for driveways, patios, walkways, and pool decks.

Application is convenient since it comes ready to use and can be applied with a roller or sprayer. One gallon covers roughly 175 to 225 square feet, which is pretty efficient. The product is self-priming, so you don’t need a separate primer coat, and reapplication is straightforward when surfaces start to look worn. The VOC content is low at 50, making it compliant with strict environmental standards in all 50 states, which is good if you’re concerned about fumes or environmental impact. However, being solvent-based means it might have stronger odors compared to water-based options and requires careful handling.

The sealer is relatively heavy (42 pounds for 5 gallons) and sized in a large container, so it’s best suited for bigger projects or professional use rather than small DIY jobs. It works well on various concrete finishes, including stamped and broom-finished surfaces, adding versatility. If you want a professional-grade sealer that enhances the look of your concrete while offering reliable protection and you are comfortable with solvent-based products, the Armor AR350 is a strong candidate. Just be ready to handle the product carefully due to its weight and solvent nature.
