Type of Sealer
Not a surface sealant but a penetrating one, similar to the chemicals used by federal DOT on highways.
Finish
The liquid is easy to apply with a roller, dries clear, and slightly enhances the look, giving a 'finished' appearance.
Durability
Rain pools in small droplets once the sealant dries, indicating effective water resistance.
Application Method
Application is straightforward and easy, and the directions are clear, resulting in a waterproof surface.

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.

Siloxa-Tek 8500 Ultra Concentrate is a high-quality penetrating concrete sealer designed to protect surfaces like concrete, brick, masonry, and pavers without altering their natural look. It uses a silane/siloxane formula, which means it soaks deep into the material rather than sitting on top, providing long-lasting water and salt resistance. This product is water-based and has low VOC content, making it a safer choice for indoor or outdoor use with less harmful fumes. It’s also breathable and won’t peel or flake, preserving the surface texture and preventing slippery finishes.

One of its standout features is durability: it’s approved by the Department of Transportation and can protect against damage from freeze-thaw cycles, deicing salts, and wind-driven rain. The sealer boasts a higher concentration of active ingredients than many competitors, promising protection that can last up to 10 years if applied properly, especially on vertical surfaces. Application is flexible—you can use a sprayer, roller, or brush, and it covers about 250 square feet per gallon per coat, which is efficient considering the concentrated formula.

Because it is a penetrating sealer, it won’t add a glossy or shiny finish if that is something you desire. This product is best for those looking to maintain a natural look while securing their concrete or masonry against moisture and environmental damage, rather than for those wanting a decorative surface change. Siloxa-Tek 8500 Ultra Concentrate is an excellent choice for anyone needing a durable, clear, and breathable concrete sealer that offers strong protection with minimal impact on appearance.

Rating

Type of Sealer
Finish
Durability

Most important from
2217 reviews

Type of Sealer
Although the solvent-based formula has a strong odor during application, it dissipates quickly and the results justify the caution.
Finish
It transforms concrete surfaces by making the aggregate 'sparkle and pop,' delivering a rich, enhanced color without haze or bubbling.
Durability
This sealer effectively locks in paver sand and protects against weather, reducing maintenance concerns even when drainage is imperfect.
Application Method
The sealer spreads smoothly with a standard paint roller, allowing precise coverage even near edges without spills or unevenness.

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.

Buying Guide for the Best Concrete Sealer

Choosing the right concrete sealer is essential to protect and enhance the appearance of your concrete surfaces. Whether you're sealing a driveway, patio, or indoor floor, the right sealer can prevent damage from water, chemicals, and wear, while also improving the look of the concrete. To make an informed decision, it's important to understand the key specifications and how they relate to your specific needs.
Type of SealerConcrete sealers come in different types, including penetrating sealers, acrylic sealers, epoxy sealers, and polyurethane sealers. Penetrating sealers are great for protecting against water and stains without changing the appearance of the concrete. Acrylic sealers are easy to apply and provide a glossy finish, making them ideal for decorative concrete. Epoxy sealers offer a durable, high-gloss finish and are often used for indoor floors. Polyurethane sealers provide a strong, abrasion-resistant finish suitable for high-traffic areas. Choose the type based on the level of protection and finish you desire.
FinishThe finish of a concrete sealer can range from matte to high-gloss. A matte finish provides a natural look and is less slippery, making it suitable for outdoor surfaces like driveways and walkways. A high-gloss finish enhances the color and texture of decorative concrete, making it a popular choice for indoor floors and patios. Consider the aesthetic you want to achieve and the surface's intended use when selecting the finish.
DurabilityDurability refers to how well the sealer can withstand wear and tear, chemicals, and weather conditions. For outdoor surfaces exposed to the elements, a highly durable sealer is essential to prevent damage from UV rays, water, and temperature changes. For indoor surfaces, consider the level of foot traffic and potential exposure to spills and stains. Choose a sealer with the appropriate durability to ensure long-lasting protection.
Application MethodConcrete sealers can be applied using different methods, such as rolling, brushing, or spraying. Rolling and brushing are suitable for smaller areas and provide more control, while spraying is efficient for larger surfaces. Consider the size of the area you need to seal and your comfort level with each application method. Some sealers may require multiple coats, so factor in the time and effort needed for application.
Drying TimeDrying time is the period it takes for the sealer to cure and become effective. This can range from a few hours to several days, depending on the type of sealer and environmental conditions. Faster drying times are convenient for projects that need to be completed quickly, while longer drying times may provide a more durable finish. Consider your project timeline and the conditions in which you'll be applying the sealer when evaluating drying times.
VOC ContentVOC (Volatile Organic Compounds) content refers to the amount of harmful chemicals released into the air during application. Low-VOC or VOC-free sealers are more environmentally friendly and safer for indoor use, as they reduce exposure to harmful fumes. If you're sealing an indoor surface or are concerned about air quality, opt for a sealer with low or no VOC content.
