Do you have an aging concrete patio or driveway?
Has your basement floor or pool deck seen better days?
While most concrete surfaces outlast their owners, most still take a beating from hard wear and exposure to the elements. Concrete sealers are designed to seal, protect, and enhance concrete surfaces.
The Top Five Concrete Sealers in 2024
I set off to find five of the best concrete sealers on the market, and I couldn’t be happier with my final selections. Read along to learn about the benefits of these amazing products. Then, discover answers to the most frequently asked cement sealer questions.
#1 Best Overall
- PENETRATING WATER REPELLENT PROTECTION: This ready-to-use water-based concrete sealer penetrates porous concrete and masonry to help reduce water and moisture absorption. Ideal for driveways, patios, sidewalks and other exposed surfaces where rain, snow and seasonal moisture can contribute to freeze-thaw stress.
- CLEAR, 100% BREATHABLE NATURAL LOOK: The clear penetrating formula helps protect concrete while preserving its original appearance without a heavy glossy or wet-look finish. The breathable treatment allows moisture vapor within the substrate to escape while helping resist outside moisture.
- FOR POROUS CONCRETE & MASONRY SURFACES: Use on properly prepared concrete driveways, garage floors, patios, sidewalks, walls, stamped concrete, brick, pavers and compatible stone. Designed for absorbent mineral surfaces; not intended for vinyl, glazed tile or other non-absorbent surfaces.
- READY TO USE — NO MIXING OR DILUTION: The low-viscosity formula is designed to penetrate porous surfaces rather than sit on top as a thick coating. Apply to a clean, dry and properly prepared surface with a low-pressure sprayer, roller or brush. Allow newly poured concrete to fully cure before sealing.
- COVERAGE FOR HOME & COMMERCIAL PROJECTS: One gallon covers approximately 150–350 sq. ft. depending on surface porosity, condition and application rate. Suitable for indoor and outdoor concrete projects including garage floors, driveways, patios and masonry; not intended as a crack, joint or gap filler.
1. Armor AR350 – Editor’s Choice and The Best Penetrating Concrete Sealer
Armor AR350 is a “wet look” solvent-based acrylic concrete sealer. It is designed to seal, enhance, and protect most indoor and outdoor concrete surfaces.
AR350 is manufactured in the United States under the strictest quality control standards.
It is made from non-recycled resins. If you take your time applying AR250 correctly, you can expect anywhere from 1 to 3 years of protection on outdoor surfaces and 3 to 7 years on indoor surfaces.
One of the reasons I love this concrete sealer is that it can be applied to a wide range of surfaces. It does not matter if the concrete you are working with has been sealed or not.
Do these 3 things before closing this tab:

Expansive Coverage
Armor AR350 is sold in 5-gallon pails. A single pail covers 875-1,225 square feet on old and porous surfaces. Meanwhile, it offers 1,250 to 1,625 square feet of coverage on dense, trowel-finished concrete surfaces. Keep in mind that these numbers are only indicative of a single coat. The manufacturer recommends two coats for most sealing jobs.
I was pleased with AR350’s ability to soak in UV rays without yellowing or peeling.
It gives concrete a wet yet non-glossy appearance.
Show off the natural beauty of your concrete with the clear formula, or cover stains and discolorations with one of the 14 alternative color options. Color offerings consist of basic black and white and various grays, browns, and reds. The neutral pallets are designed to give aggregates a natural appearance.
Countless Uses
I couldn’t be more pleased with the versatility of this cement sealer. It can be used on an exceptionally wide range of surfaces, including poured stamped and exposed aggregate concretes. It is also an excellent option for pool decks and patios. I recommend that you amend it with some non-slip additives when using it on outdoor surfaces. When I tested it out, I had no issues with adhesion.
If you have concrete that takes a beating because of harsh environmental factors or job site realities, AR350 is a worthwhile investment. These inexpensive pails provide long-lasting protection and aesthetic improvements. I loved watching rain bead as soon as it came in contact with this cement sealer.

Chemical Formula
First off, let’s weigh the pros and cons of the different types of cement sealers, which include:
- Penetrating Sealers
- Acrylic Sealers
- Polyurethane Sealers
- Etc
Most penetrating sealers are made from siloxane, siliconate, silicates, or silane. These formulas penetrate the pours of cement without changing its appearance. They are usually resistant to water, chemicals, minerals, and UV rays. Penetrating sealers are a good choice if you:
- do not want to change the appearance of the cement
- want to avoid damage from environmental factors
- are looking for an environmentally friendly cement sealer
On the other hand, acrylic concrete sealers are made from a mix of acrylic compounds and solvents or water. They may be colored or clear. They are typically available in a variety of sheens. Acrylic sealers are ideal for sunlit patios and patios. They are a good choice for individuals:
- Looking to achieve aesthetic improvements
- Looking for a quick, inexpensive solution
- Looking to protect vulnerable outdoor surfaces and looking for the best epoxy resin for river tables.
Epoxy and urethane mixtures are also popular topical sealant options. These types of cement sealers tend to be more costly.

These formulas may be water- or solvent-based. They are a good option for homeowners looking to:
- Spend less

- Retain the natural beauty of a cement surface
Protection
Are you still unsure if the concrete sealer is worth the investment? Concrete sealers protect aggregate surfaces from unsightly staining and wear. When applied correctly, sealers create an impenetrable and typically indivisible layer of protection.
In most cases, they block the pores, allowing moisture to exit but never enter the material.
Common forms of concrete damage include stains, scale, and abrasion. A quality cement sealer will prevent all this and more. It may even prevent chemicals, chlorides, and salts from penetrating the pores.
Coverage
You must ensure that you have enough products to cover your target area. Most manufacturers offer expected coverage rates. However, coverage may vary depending on the porosity of the cement. Moreover, you may be required to apply both a base and topcoat. Coverage rates range between 50 and 400 square feet per gallon.

Application Options
One of the most common questions regarding concrete sealers is how to apply them. In most cases, I suggest you follow the manufacturer’s instructions to achieve the best possible results. Nevertheless, the following tips and tricks will help you make the most out of your cement sealer:
- Put in the Extra Elbow Grease. I strongly advise you to clean your cement before sealing it. Remove stains, dirt, and debris to the best of your ability. First, sweep the surface. Then, use cleaner to scrub away any stubborn spots. Then, apply the cleaner all over using a mop. After that, use a shop vacuum to lift any remaining residue.
- Fill Cracks. Take the time to fill any cracks and gouges in your cement. Use matching cement to fill in the spaces. Give it a proper amount of time to dry and cure. Cement sealer works best when applied to a smooth, uniform surface.
- Remove the Old Sealer. You may need to remove the old cement sealer before applying the new one. Steps for this vary depending on the type of sealer. You must remove the old sealer if it is different from the new one you wish to apply.
- Use the Right Applicator. Most manufacturers will tell you exactly how to apply their cement sealer. Popular application methods include rollers, brushes, and sprayers. Pay close attention to the direction and timing of your application. Moreover, make sure the temperature and humidity are within the recommended range. In most cases, sealers dry within 6 hours and cure within 24 hours. You’ll need to do your best to avoid precipitation, cold spells, and foot and paw traffic during this period.
Surface Compatibility
Cement sealers are designed to go over a variety of industrial aggregate surfaces. Some are even specifically designed for indoor and outdoor applications. Learn to disseminate between the different types of cement, as it will make it easier for you to choose a sealer for your particular finish.
Common cement textures include exposed aggregate, troweled, salt, stamped, and broom finishes. Sometimes concrete is stained or polished.

Frequently Asked Questions

The short answer is no. It’s not necessary to seal concrete before painting. However, a concrete sealer will help you avoid surface stains, filth, and abrasions. Cement sealer is a low-cost home improvement project. Not to mention, it’s a project that you can do in one afternoon.
Are there environmental or health issues associated with cement sealers?
