Do you have some concrete cracks in your sidewalks or walls that need fixing? Or do you just need to improve the appearance and durability of your concrete floor?
Concrete sealant is the answer. Some cracks just don’t look good while others, like gaps in sidewalks, can be downright hazardous.
If you’re all set to learn how to seal concrete, we’ve got some handy tips for you. This guide will navigate you through the process, including the frequency of sealing, the selection of the right sealant, and its application.
Key Takeaways
- Sealing concrete protects it from damage, keeps it looking good, and makes it last longer.
- It’s usually best to seal concrete every 3 to 5 years, but this can change based on weather and how the concrete is used.
- There are many types of sealers, including epoxy and silicon-based ones; choosing the right one depends on what your concrete needs.
- Before sealing, it’s important to clean the concrete and fix any cracks for the best result.
- If you face issues like bubbles or the sealant not sticking, you may need to apply the sealer again after preparing the surface or consider getting help from a professional.
Benefits of Sealing Concrete With A Concrete Sealer
The benefits of sealing your concrete are significant and varied, offering not only protection from the elements but also extending its lifespan. When you seal your concrete, you’re giving it a shield against moisture, which can cause it to weaken over time.
Additionally, sealed concrete surfaces are easier to clean and resist oil stains and chemical discoloration, keeping your space looking clean and fresh.
You’re also protecting it against freeze-thaw damage, a common problem in colder climates. Plus, let’s not forget about aesthetics. A sealed concrete surface looks better, enhancing its appearance and, in turn, raising your property value.
Frequency of Sealing Concrete
While you understand the importance of sealing a concrete surface, it’s also crucial to know how often you should do it. Typically, concrete should be sealed every 3 to 5 years.
However, this frequency can vary depending on your climate.
For instance, if you live in an area with extreme weather conditions, you might need to seal your concrete more often. It’s also important to note that different concrete surfaces may require different sealing frequencies.
For example, a driveway may need to be sealed more frequently than basement or garage floors.
To ensure you’re sealing your concrete at the right frequency, consider consulting with an experienced contractor. They can provide you with a tailored plan that ensures your concrete stays protected and looks great.
Types of Concrete Sealants
Once you’ve determined the right sealing frequency, it’s time to choose the type of concrete sealant that’s best suited to your needs.
There are several types of concrete sealers available, each with its own benefits.
- Epoxy coatings are tough and durable, making them great for high-traffic areas.
- Silicon-based sealants offer excellent water resistance.
- Water-based and solvent-based acrylic sealers are easy to apply and dry quickly.
- Penetrating sealers sink into the concrete to offer protection from within
- Densifiers and polyurethane coatings add a layer of protection on the surface.
The best sealant for you depends on your specific requirements, like the concrete’s location and usage.
Preparing Concrete for Sealing
Surface preparation will enhance the effectiveness of the sealant and ensure a smoother application.
First, clean the surface thoroughly. Use a power washer to remove dirt, grime, and old sealant. Then, give it a good scrub with a detergent. This will get rid of any oil or grease stains that could prevent the sealant from adhering properly.
Next, patch any concrete cracks or holes using a concrete patch product. Make sure the surface is completely dry before you start sealing. If it’s been raining or if the concrete is new, you may need to wait a few days.
Timing, Dry Time, and Temperature Guidelines for Sealing Concrete
It is important to consider the timing of sealing concrete. Follow these guidelines:
- Make sure new concrete has completely cured, which usually takes at least 28 days or as recommended.
- Sealers should be applied on dry concrete to avoid haziness or loss of adhesion.
- Ensure that the air temperature is above 50°F during the application of the sealer and continues to be so for a minimum of 24 hours after.
Seal Your Concrete With These Easy Steps
After you’ve thoroughly prepared and dried your concrete surface, it’s time to move on to the next step: applying the sealant.
Start by selecting the right sealant for your needs. Options include epoxy coatings, silicon-based sealers, or water-based acrylics. The choice depends on your desired outcome and the specific requirements of your surface.
To apply the sealant, use a roller or brush and spread it evenly across the surface, ensuring coverage in all areas, including hard-to-reach nooks and crannies.
Then, give it time to dry. This may vary depending on the sealant type, so follow the manufacturer’s instructions for optimal results.
Troubleshooting Sealer Application
Despite your best efforts, you might encounter a few problems during the sealer application process.
You may notice bubbling, a sign of trapped moisture or air. In such cases, you’ll need to reapply the sealer after properly drying the surface.
Hazing or a white, powdery residue means there’s an excess sealer. To fix this, you can simply strip and reseal the surface.
If the sealer’s not sticking, it’s likely because the concrete wasn’t clean when you applied it. You’ll have to strip the sealer, clean the surface, and then reapply.
Always remember to follow the manufacturer’s instructions to avoid these issues.

FAQ
Does the concrete need to be sealed?
Yes, concrete needs to be sealed, especially for outdoor areas like your patio or walkways. The sealing process prevents the porous surface of the concrete from absorbing water, which can cause damage.
Can you seal concrete yourself?
Yes, you can seal concrete yourself. It’s a relatively straightforward DIY task that doesn’t necessarily require professional help. You can make use of the best concrete sealer suitable for your concrete countertop, driveway, or patio.
How soon after pouring concrete should you seal it?
You should seal new concrete as soon as the surface is dry enough to walk on without leaving an impression. Usually, this is around 28 days after pouring.
What to do before sealing concrete?
Before sealing concrete, you must ensure the surface is clean and free of any existing sealer or impurities. Using a pressure washer can help clean the surface thoroughly. Also, ensure the concrete is fully dried and cured before applying the new sealer.
What is the downside of sealing concrete?
The downside of sealing concrete is that it may change the appearance of the concrete, sometimes darkening its color. Also, the sealer is subject to abrasion and may need to be reapplied regularly to maintain its effectiveness.
What happens if you don’t seal concrete?
If you don’t seal concrete, it can become susceptible to damage from moisture absorption. This is because concrete is naturally porous. Existing concrete without sealer can degrade more quickly, leading to cracks and other forms of damage.
