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. 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.
I love that AR350 helps reduce damage and deterioration caused by surface abrasion.
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.

Its environmentally friendly ingredients earned its official U.S. Department of Transportation approval. The formula is safe and effective. Not to mention, it is non-flammable.
I love that this formula is clear and non-glossy. Keep in mind that it does have a wetting effect on most concrete surfaces. The sealer goes on easily with the help of a spray or brush.
It penetrates deep, closing pores off from naturally occurring moisture and minerals.
Coverage rates vary when it comes to different surfaces. On most concrete, you get 150 to 250 square feet of coverage per gallon. Whereas you only get 125 to 175 square feet of coverage on brick. Finally, you get around 50 to 100 square feet per gallon on split-face blocks.
Impressive Customer Service
There’s nothing worse than dealing with subpar customer service. Fortunately, ToughCrete backs all its products with lifetime guarantees and a proprietary 10-year tough promise. After speaking with a number of their customers, I am confident in the company’s hassle-free approach to customer service. In many cases, the representatives have taken the time to answer customer questions and get a refund.

This product’s ease of application is undeniable. You can apply it quickly and easily with a sprayer, roller, or brush. Typical drying times range between 4 and 6 hours.

According to the manufacturer, this product should be good for 100 years.
This is one of my top cement sealers for decorative surfaces, such as patios and pool decks. However, it works well on hard-wearing substrates, including garages, driveways, workshops, and basements. The water-based silanes and siloxanes create a nearly invisible yet wholly effective barrier.

While some customers found this product wore off too soon, I felt it offered extensive and reliable coverage. As in most cases, poor results may be caused by high humidity, poor prep work, and inferior application.

How to Choose a Concrete Sealer
It can be challenging to disseminate when the seemingly countless different concrete sealers on the market. From penetrating formulas to acrylic base coats, there are plenty of products that serve to protect industrial aggregates.
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.
Lastly, polyurethane concrete sealers are common topical options for indoor aggregate surfaces. These formulas may be water- or solvent-based. They are a good option for homeowners looking to:
- Spend less
- Fix up garages and workspaces
- 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.
Aesthetics
Many people do not realize that concrete sealers are available in a variety of finishes. After all, most penetrating sealers generate clear, no-gloss coatings. On the other hand, topical sealers come in a variety of sheens. Some are even available in various colors. Some sealers can also be amended with non-slip aggregates. It is up to you whether you want to change the look and texture of your cement.
