Best Concrete Sealer (2022): Reviews & Comparison 

Concrete is very porous and requires maintenance over time, it tends to suck up water, liquids, or any other material it comes into contact with. The exposure to water, ultra violet rays, chemicals, and wear and tear can damage the concrete and the presence of water can also cause the growth of mold and mildew that can damage the structural integrity of your home in the long run. This is why it is extremely important to seal concrete.

You can preserve the new concrete in your home by using the high quality sealant. In this guide, we deep dive into the types of concrete sealers and their functions to help you choose the right concrete sealer for your project.

Our Reviews of Concrete Sealers

Concrete is porous and vulnerable to water, UV rays from the sun, chemicals, salt, mold and mildew growth, and general wear and tear and all of these can damage its surface. Over time, the onslaught of all these elements can cause the concrete to crack. The best way to protect concrete driveways, floors, pavers, walkways, countertops, and other concrete surfaces in your home is by using a high quality sealer.

Applying a high-quality concrete sealer can help create a protective shield that offers invisible protection for the various concrete surfaces in your home and also prolong the life of the concrete by covering the cracks; preventing damage caused by de-icing salts in the winter; preventing water seepage through the basement, walls, and foundation; preventing the concrete from pitting and spalling; and improving the appearance of the concrete surface by adding shine.

Other Concrete Sealer Types to Consider

There are so many types and brands of concrete sealers on the market that choosing the right one can be quite confusing. The best choice for a concrete sealer depends on various factors such as the type of concrete surface you are sealing, the type of concrete sealing job, and whether you are sealing interior or exterior concrete.

What Is Concrete Sealer?

Concrete sealer is a chemical that is applied to concrete before sealing. A sealer will protect your concrete by repelling water, preventing stains, and keeping dust, dirt and other particles from penetrating into the pores of the concrete. This will add ease of maintenance to your concrete project and extend the life of the project.

Factors to Consider When Choosing a Concrete Sealer

When it comes to sealing your concrete, there are a few factors to consider for your concrete sealing project. For home use, you'll want a basic sealer that helps protect against water damage, mold and other weathering. Concrete sealers can be used on driveways, patios, sidewalks and any other area that is made of concrete. There are many different types of sealers with different pricing and application methods.

Surface

Use a concrete sealer that is formulated for your particular project. For instance, if you intend on polishing the final product, you will want to go with a semi-gloss. If you plan on leaving the surface textured, or if your concrete hasn't been sealed in years, choose a water-based or epoxy sealer.

Exterior Concrete Surfaces: Because it renders a protective barrier that prevents water penetration and may ward off stains and discoloration, penetrating sealers are your best bet for ideal exterior concrete sealing. It also provides protection against salt and chemicals that might be introduced to the surface of your concrete through weathering or other means of wear.

Decorative Concrete Surfaces: When sealing your decorative concrete, you want to make sure you use a high-quality sealer that will not only protect the surface but also enhance its color and character.

Concrete Countertops: Sealer forms a protective shield on the concrete to prevent stains and other things that can ruin your countertops. Make sure you have the right sealer, some are better at protecting than others.

Concrete Floors: Concrete floor sealer is what best protects your concrete floors. As an investment, you should want to protect the overall integrity and quality of your concrete floors — from being able to withstand years of wear and tear.

Exposed Aggregate: Sealing your exposed aggregate concrete will make it last much longer. This is one of the most important steps in the process when it comes to sealing exposed aggregate concrete.

Concrete Driveway - Driveways are, whether it is an asphalt driveway or a concrete driveway; very important to the property as well as to the homeowner. For minor repairs and for complete coatings, you will need concrete sealer.

Finish

When shopping for a concrete sealer, it is important to decide which type of finish you want. Different finishes will give your concrete a more professional and tailored look, so be sure that you know what different types of finishes there are — and what each does.

Durable finish: Durable finish refers to the quality of the coating a sealer has on it. The protective coat should be thick enough to protect your concrete from any elements (such as water, UV rays, or chemicals) that may compromise its integrity.

Natural finish: This is a natural look sealer that is a translucent color. Most of the time you won't see much of a difference between the concrete with and without it, other than the surface being shinier.

Glossy finish: A glossy finish on a sealant gives elegant sheen levels on the surface of a floor. The term "wet look finish" is more commonly used for concrete sealer, and it is also known as shiny finish.

Broom finish: Broom finish is the process by which sealer is applied to concrete so that it looks like a broom has been dragged over the surface. This gives an appearance of high-quality, professional work, and the sealer protects your concrete from moisture, stains and other damage.

Base

Traditional concrete sealers are solvent-based and can leave a sticky residue on the surface of your concrete. Water-based concrete sealer, on the other hand, is eco-friendly. Not only is it safer for use around people and pets, it's still just as effective as its solvent-based counterpart.

Water Based Sealer: Water based formulations are high-performance sealers with a low sheen and are generally low in VOC. The polymer particles are typically dispersed in water in a water-based sealer and when the water-based sealer is applied to the concrete surface, the polymer particles get closer when the water evaporates. As the water continues to evaporate, the particles get deformed and bond together, forming a clear and continuous coating.

Solvent Based: Solvent-based acrylics are widely used for outdoor concrete surfaces, which help to augment the color of the concrete and also protect the surface. In a solvent-based concrete sealer, unlike the water-based ones, the polymers do not exist as separate particles. The solvent and the polymer are mixed for a clear and continuous solution.

Epoxy Concrete Sealers: Epoxies are essentially a thermosetting polymer coating which also acts like a concrete sealer. These types of concrete sealers form a high-build film on the surface of the concrete and produce a hard finish which is resistant to abrasion and wear. Epoxy sealers are also water repellent.

Acrylic Concrete Sealers: Acrylic sealers require a very thin coating to be applied and they dry very quickly when applied. Acrylic sealer is suitable for both indoor and outdoor use and is known as a film forming sealer. Film forming sealers form a protective film that offers protection against the intrusion of water and chloride, while allowing the moisture in the concrete surface to escape, which makes these sealers ideal for use around the pool areas.
