7 Best Concrete Sealers of 2024

This is an industrial-grade water-based sealer, so you know it will protect your concrete surfaces from the weather. It resists de-icing, freezing, rainfall, thaw damage, pitting, and cracking.

It protects the concrete and the substrates from salt and chlorides, and it has excellent water beading qualities. This siloxane sealer is different from the others because it penetrates deep into the material, protecting it from within.

The key thing is there is no aesthetic change to the look and feel of the concrete. It doesn’t dry with a high sheen, plus it has low VOCs (volatile organic compounds), so it is good for your health and the environment.

You can use it on driveways, patios, pool decks, and basement floors, so it is a multi-use sealer, and it covers up to 250 square feet per gallon per coat. It also is guaranteed to never yellow or fade through UV damage, so it will stay looking great for years.

The only downside is this sealer is thin, so if you are working on an incline, it may run downhill. Plus, it takes some practice applying it because the second coat has to be put on when the first coat is still slightly wet.

This concrete sealer uses nanotechnology to form a protective and waterproof barrier over your concrete and masonry surfaces. It can be used indoors and out, so it is versatile, and depending on the surface porosity, you should get between 75 to 125 square feet of coverage per 1-gallon can.

This water-based paint is water-resistant, mold and mildew-resistant, and cleans up easily with soap and water. It is low VOCs and better for the environment because it doesn’t need a mineral spirit to get it clean.

This paint dries to the touch in 1 hour and can be re-coated in 4 hours. And because it is waterproof paint, you can spray it, brush it on or use a roller.

The only negative is it only comes in white, so you are limited to choice, and if you don’t want to change the color of your concrete, you might be better off picking a clear sealer.

The epoxy concrete sealer dries hard to form a super-protective coating that is almost impenetrable. It means the rain and UV rays of the sun will not fade or yellow this resin. It’s also marine-grade, so it deals with salt and chlorides better.

It is self-leveling, easy to pour and mix, with a 1:1 ratio, and it bonds to concrete, masonry, metal, wood, and ceramics, so it has a multitude of uses.

It dries crystal clear, preserving the concrete surface below, and it contains zero VOCs and is BPA-free. This means it’s great for the environment, your health and for easy cleanup with soap and water.

The downside is you get a much-reduced coverage with this epoxy because it is a 2-part process, with a 0.5-gallon hardener and epoxy. You only get 6 square feet per mixed 1-gallon quantity, which is a lot less than the sealers featured on this list.

It’s also expensive compared to other similar products. And if you are working on a large area, it could cost many times more than other sealers.

This Armor concrete sealer dries with a wet look and a low-gloss finish. It is made from non-recycled resins, so it isn’t the greenest product to feature. It’s also solvent-based, so it will pollute the environment.

It is breathable, non-yellowing, and self-priming, so you apply it to unsealed concrete and paver surfaces, as well as surfaces previously sealed with a solvent-based product.

This sealer reduces instances of pitting, cracking, and spalling caused by surface abrasion. Once down, it can last up to 3 years outdoors and 5 to 7 years indoors.

The negatives are that this sealer will darken the surface of your concrete, and it is extremely harmful to the environment. However, it is UV resistant and has low VOCs.

Also, it is eye-wateringly expensive. It costs over $200 for a 5-gallon tub. If we look at the price per gallon, it is comparable with others, but to spend this much, you have to be sure you need 5 gallons.

This water-based siloxane sealer is guaranteed never to color, stain, or darken your concrete surfaces. If you want to keep your concrete looking as you intended but still protected from the elements, this sealer is the one to get. It dries invisible.

Thanks to the siloxane rain guard, it binds with the minerals in the concrete to form long-lasting protection from water. You should get 5 years of protection between new coats, and because it’s a penetrating sealer, it creates a barrier within the concrete.

It’s easy to apply with a pump-action garden sprayer, and you should get between 90 to 150 square feet of coverage depending on the porosity of the concrete surface. It safeguards against pitting, freeze-thaw, staining, salts and chloride, and so much more.

The only downside is a sprayer is less accurate than a brush or roller, so be prepared for overspray.

If you want the best possible coverage for your stamped concrete, this Dominator offers up to 400 square feet of coverage, depending on the texture of your pavers or pattern.

Just like the MasonryDefender product, you get a 5-year warranty against the sealer failing, and it is solvent-free, with no odors and low VOCs, so it’s better for you and the environment. It also cleans up with soap and water.

You get UV protection, stain resistance, fade resistance, and it even restores sun-washed colors. It dries to the touch in 4 to 6 hours and cures in 24 hours, but wait for 48 hours if you are subjecting it to heavy footfall.

This Dominator is pretty costly for a 1-gallon container, so it might limit the size of your projects.

This is another water-based concrete sealer, which is excellent news for the environment as it washes clean with soap and water. What caught our attention was the 10-year warranty you get with this product. That’s a lot of weatherproofing between re-coats.

This is a penetrating sealer, so your driveway will not change appearance when it is applied, and the formula soaks deep into the material to form a water-resistant layer. It also protects against stains such as oil, gas, and antifreeze, so when you are maintaining your vehicle, it won’t ruin the concrete driveway.

You get total protection against ice, freezing, chemicals, and wind-driven rain. It also protects against mold and mildew, and it will not alter the appearance of your driveway.

Again, this is a spray-applied formula, so it is thin and not great for driveways on a steep incline. You also get less accuracy with a sprayer.
