Editor’s Note: Check out our article on the best garage floor coatings to see our top recommendations for that particular application.

How Long Do Concrete Sealers Last?

There are a few different types of concrete sealers for indoor and outdoor use, and how long your sealer lasts depends on several factors. We’ll break it down and make it easy for you to understand what matters when choosing a product.

Some Types of Concrete Sealers Last Longer Than Others

The product type is the biggest factor determining how long your concrete sealer will last. Choosing the best concrete sealer for your project is important, as some sealers have specific uses and don’t work for all types of concrete, stone, and brick.

The two basic types of concrete sealers are film formers and penetrators, and they perform in different ways. Depending on which you choose, your concrete sealer could last anywhere from 1 to 10 years before requiring a recoat.

Film Formers

Acrylics, epoxies, and urethane coatings form films that cover the surface of your concrete. They provide a layer of protection and make your concrete easier to maintain.

  • Acrylic concrete sealers – Last 1 to 3 years
  • Epoxy coatings – Last 5 to 10 years
  • Urethane coatings – Last 5 to 10 years

Penetrating Sealers

Penetrating concrete sealers are available in solvent and water-based systems and continue to react with the concrete over time. They don’t change the appearance of concrete, but they work to repel moisture and stains. 

  • Silicate concrete sealers – These never break down, they densify and harden concrete and continue to react with it chemically throughout the life of the concrete
  • Penetrating silane siloxane concrete sealers – Last six months to 10 years, depending on the product
  • Silicone water-repellent sealers – Create a chemical bond that lasts for six months to 7 years, depending on the acid content and the quality of the product

Other factors that influence the longevity of your concrete sealer include the quality of the product, how you apply it, and how many coats you used.

Best Patio Concrete Sealers

Invest in the best patio concrete sealers to preserve the life and beauty of your outdoor living spaces. Using the right product to seal a concrete patio enhances its appearance and increases its durability, so you don’t have to worry about expensive repairs.

Foundation Armor SX5000 WB – Silane-Siloxane Sealer

Foundation Armor SX5000 WB - Silane-Siloxane Sealer

Foundation Armor offers the SX5000 WB silane-siloxane sealer for a penetrating water-based solution that provides lasting protection against water and salt. It will preserve the appearance of your concrete patio without changing the texture, color, or natural beauty of your concrete finish.

Ghostshield Lithi-Tek 9500 works on brick, pavers, and cinder blocks. Use it as a substitute for foundation concrete membranes and concrete vapor barriers.

Best Driveway Concrete Sealers

Concrete driveways are subject to more damage than other concrete surfaces. They have to be able to sustain the weight of heavy vehicles, and they are out in the open, where UV rays, water, and temperature changes can cause deterioration. Add oil spills and grass stains, and it’s easy to see why you need the best concrete sealers for driveways.

DryWay Plus – Water-Repellent Concrete Sealer

DryWay Plus - Water-Repellent Concrete Sealer

DryWay Plus is a deep-penetrating sealer that’s been tested and approved by the DOT (Department of Transportation).

You can use DryWay Plus as more than a concrete driveway sealer, however. It also works great for retaining walls, garage floors, pavers, sandstone, and terra-cotta. There’s no need to use slip-resistant additives either because DryWay Plus won’t change the look or texture of your driveway.

Use a sprayer for even application that won’t pick up dirt when you’re applying on outdoor surfaces with joints like pavers, clay bricks, flagstone, or slate.

Benefits of Using Concrete Sealers

Concrete sealers offer numerous benefits to improve the appearance and durability of your project. Learn more about the benefits of using concrete sealers.

Protection against Stains

One of the most popular reasons to seal concrete is to improve its appearance and keep it from staining. Because concrete is a porous material, it gets stained by many substances, including grass, leaves, oil, and dirt. Even spilling a glass of wine on your concrete can stain it unless it’s properly sealed.

Water Resistance

Water is one of the biggest enemies of concrete because it enters the pores and then freezes and thaws. With the right concrete sealer, you can make your concrete surfaces more impervious to water, which will reduce the amount of damage caused by water.

UV Protection

Concrete is strong, but it’s really only held together by chemical bonds, which can weaken over time. UV rays break the chemical bonds in concrete and weaken the polymers that hold it together. A good concrete sealer will provide a layer of protection between the damaging rays of the sun and your concrete.

Enhancing Appearance

Concrete sealers can make dull concrete look beautiful by protecting your concrete surfaces from damage and staining. You can also choose colored concrete sealers to enhance the look of your surfaces.

Durability and Longevity

Concrete is a durable material, but it won’t last forever. Protecting it with a sealer ensures that your concrete surface will last longer and be protected against damage caused by temperature changes, tools, de-icing products, corrosion, and heavy vehicles.

Frequently Asked Questions About Concrete Sealers

Why should I use a concrete sealer?

Concrete lasts a long time and will last longer and look better with a concrete sealer. Sealing concrete protects it from damage, water, UV rays, and stains while enhancing its appearance.

When is the best time to apply a concrete sealer?

The best time to apply concrete sealer depends on where you live. The best time to seal concrete in the southern United States is from late fall to early spring, while summer and fall are the best time to apply concrete sealer in the north. You should always use the 50°F (10°C) rule when applying concrete, and never apply it in temperatures below that. The best time of day to seal concrete is late afternoon or early evening.

And, of course, sealing concrete prior to moving into a new home always makes more sense to us verses having to move everything out to do the job!

How long does a concrete sealer last?

Different types of concrete sealers have various longevities. Acrylic concrete sealers usually last about 1 to 3 years, while epoxy and urethane coatings last 5 to 10 years. Many types of penetrating concrete sealers last as long as the concrete does.

How do I prepare the concrete surface before applying a sealer?

Concrete is a porous material. You must clean as many trapped particles and stains as possible before sealing it. Remove the oil, grease, dirt, and stains, and strip the existing sealer if you have one. Then, open up the pores of the concrete with an etching solution so it will absorb the new sealer. Apply at least two thin coatings, letting the sealer dry completely between layers.

Can concrete sealers be applied to colored or stamped concrete?

Colored or stamped concrete is designed to be sealed because it enhances the appearance, enriches the color, and protects the durability and longevity of the concrete. There are many different types of colored concrete sealers, so be sure you know the advantages and disadvantages of each one and apply them according to the manufacturer’s directions.
