How Long Does Sealant Last on Concrete?

Concrete is an incredibly versatile and popular building material, prized for its durability, strength, and versatility. However, like any material, it's subject to the elements, and over time, it can start to show signs of wear and tear. One of the best ways to protect your concrete from damage is by using a sealant, which can help to prevent water, oil, and other substances from penetrating the surface. But how long does sealant last on concrete, and how can you tell when it's time to reapply? Here's everything you need to know.

What Is Concrete Sealant?

Concrete sealant is a protective coating that's applied to concrete surfaces to help prevent damage from water, stains, and other substances. It's typically made from a combination of acrylic, epoxy, or urethane resins, and it can be clear or colored depending on your preference. Sealant is a great way to protect your concrete from the elements, but it's not a permanent solution - over time, it will wear down and need to be reapplied.

What Factors Affect Sealant Longevity?

The lifespan of a concrete sealant depends on several factors, including:

Quality: Higher-quality sealants tend to last longer than lower-quality ones because they're made with more durable materials and have a better application process.

Climate: If you live in an area with extreme weather conditions, your sealant may not last as long as it would in a more moderate climate. Frequent freeze-thaw cycles, high humidity, and severe temperature fluctuations can all contribute to sealant breakdown.

Traffic: If your concrete surface sees a lot of foot traffic or vehicle traffic, the sealant may wear down more quickly.

Appearance: If you're using a colored sealant, it may start to fade or discolor over time, even if it's still providing protection.

How Long Does Sealant Typically Last on Concrete?

On average, a concrete sealant will last between 3-5 years before it needs to be reapplied. That being said, the actual lifespan of your sealant will depend on the factors mentioned above. If you're using a high-quality sealant and live in a moderate climate, you may be able to go longer than 5 years before needing to reapply. On the other hand, if you're using a lower-quality sealant and live in an area with extreme weather conditions, you may need to reapply after just a year or two.

Signs That It's Time to Reapply Sealant

So how can you tell when it's time to reapply your concrete sealant? Here are some signs to look out for:

1. Water doesn't bead up on the surface anymore: One of the primary benefits of sealant is that it helps to repel water. If you notice that water is starting to soak into your concrete instead of beading up on the surface, it's a sign that your sealant is wearing down.

2. Stains are starting to set in: If you're noticing more stains on your concrete surface than usual, it's a sign that your sealant isn't providing as much protection as it should be.

3. The surface is starting to look dull: Over time, sealant can start to wear down and lose its shine. If your concrete surface is looking dull or lackluster, it may be time to reapply.

4. The sealant is peeling or flaking: If you can see pieces of sealant coming off your concrete surface, it's definitely time to reapply.

5. You've had it for more than 5 years: Even if you're not noticing any of the other signs mentioned above, it's a good idea to start thinking about reapplying your sealant once you hit the 5-year mark.


In summary, concrete sealant is an excellent way to protect your concrete surfaces from damage, but it's not a permanent solution. Depending on the factors mentioned above, you can expect your sealant to last anywhere from 1-5 years before needing to be reapplied. Keep an eye out for the signs mentioned above, and be sure to reapply when necessary to keep your concrete looking great for years to come.
