The 7 Best Concrete Sealers of 2023

Best Overall

BEHR PREMIUM Wet Look Concrete Sealer

4.8

View On Home Depot

This concrete sealer from BEHR PREMIUM is our top choice since it works very well to protect and give a polished look to concrete. It enhances the durability and longevity of your concrete finish. You can use it alone to seal the concrete or brick surface, and it comes in a gallon container, making it convenient for both small and large projects. Since it is transparent, you can use it as a sealant on top of other finishes, like paint.

It is acrylic-based, so it won't fade or alter the color of most surfaces. If you have tile inlays or other surfaces around your concrete that are extremely sensitive, you may want to test a small area first before applying it to the entire area. It is safe to use indoors as well, although you should make sure that you have adequate ventilation. You can use soap and water to clean up any messes or spills.

It does take a minimum of one hour to dry to the touch. Be sure to wait a full 24 hours before walking on the surface and at least 72 hours before placing heavy items, such as furniture or other objects, back on it. It is also recommended to wait 14 days before driving on it and 30 days before washing it down with soap and water.

Best Budget

Rust-Oleum Moisture Stop Fortifying Sealer

View On Amazon View On Home Depot

The Rust-Oleum strengthening sealer is a good option if you need to add a sealant layer but don't want to break the bank. When applied to uncoated concrete, it prevents moisture from penetrating and protects against salt and radon.

Since it is a penetrating sealant, it forms a chemical barrier against liquids and vapors by reacting with the concrete. After application, you should wash the area to remove any residue. For optimal results, let the sealant sit on the uncoated concrete for 45 minutes to allow for penetration and then for another 2 hours. Keep in mind that you must wait until this sealant has dried before applying paint or any other finish. You can treat up to 200 square feet with just one gallon of this stuff.

Black Diamond Stoneworks Wet Look Natural Stone Sealer

View On Amazon View On Walmart

To achieve the appearance of wetness on concrete pavers, driveways, patios, sidewalks, and other outdoor surfaces, seal them with this concrete sealer from Black Diamond Stoneworks. It enhances the surface's luster without altering the concrete's color or texture in any way. As a result, it acts as a shield against the corrosive effects of dirt, sunlight, chemicals, and everyday use. It works equally well with both bare concrete and concrete that has been painted. 

About 600 square feet can be covered with a single gallon. You'll need some tool to spread the sealant out evenly, whether it's a spray bottle, a roller, or a brush. While the high gloss finish gives the surface a nice shine, it also means any imperfections will stand out, so be sure to apply this carefully.

Best for Driveway

MasonryDefender Concrete Sealer with De-Icing Salt Protection

View On Amazon View On Walmart

Your driveway will be safe from water damage with the help of this transparent concrete sealant. It is safe to use on poured concrete as well as pavers, including those with a design. It will protect the surface against de-icing salts, an important aspect for driveways and walkways in order to make them last longer without damage. After being applied, the concrete surface becomes impermeable to water. This keeps it from creating cracks and pits over time. One coat lasts for around five years and comes with a three-year warranty for horizontal surface application.

As much as 150 square feet can be covered with just 1 gallon. To apply, you'll need a high-pressure sprayer. Before applying the sealant, it is also a good idea to use a pressure washer filled with water to clean the driveway thoroughly. You should wait at least 24 hours after applying to make sure the surface is dry. Depending on the conditions, the curing process may take even longer.

Best for Garage

Foundation Armor AR350 Wet Look Sealer

View On Amazon View On Wayfair View On Home Depot

This sealer's low gloss creates a sleek look that is perfect for a garage or workshop. This cement sealer will give your floor a smooth, finished appearance without the expense of replacing the flooring. It resists common types of damage, including cracking, peeling, flaking, and pitting. It will also protect against salt damage, so you don’t need to worry about your tires getting salt or other debris on the surface. Additionally, it prevents the growth of mold and mildew, two problems frequently encountered in damp garages. 

Coatings should be reapplied every one to three years for optimal performance. Because you'll have to clean out your garage entirely, this can be time-consuming and labor-intensive. It comes in a large quantity, more than enough to cover your carport, driveway, and any walkways around your house. It is shelf-stable, so you can also save it for future touchups or recoats.

Best Waterproof

Gorilla Waterproof Patch & Seal Liquid, Clear

View On Amazon View On Home Depot View On Walmart

This coating does double duty as a concrete patch and a weatherproof sealant. It comes in a clear, black, or white finish. You can also paint over it without affecting the waterproof barrier. A brush, roller, trowel, or even just pouring it on the surface will work for the application. You should ensure that it coats evenly, especially if you use it in places that are not level and where water tends to pool.

The container is a bit smaller than the other options. It is ideal for smaller projects or touch-ups where you really need that extra layer of protection. You can use it without worrying about damaging concrete, wood, brick, metal, or even some plastics. This makes it a great option to have on hand for spot use.
