How to properly apply the concrete sealer
Repairing or maintaining your concrete surface by sealing the cracks or fillers is simple. But you need to follow the right steps so that you do a great job and prevent further damage. Also, check the instructions provided by the sealer to ensure a long-lasting impression. There are two ways of sealing the concrete. You can either use a sprayer or a roller. The choice is yours. You will also need a degreaser, scrub brush, putty knife, mop, concrete filler (if required), and a sealer.
- Begin by removing everything from the surface. Note that the sealer only functions if it is applied on the whole surface.
- If there is anything along the edges, it should as well be removed. This includes grass or baseboards. If you are sealing indoors, the windows should be opened.
- Rigorously sweep the concrete surface in order to get rid of all dust and other particles on the surface.
- Utilize a degreaser to remove any traces of oil or grease on the driveway or garage floor. Try as much as possible to scrub all the stains off.
- Finish the cleaning process by mopping the floor and getting rid of any remaining traces of chemicals or dust. Then, allow the concrete surface to dry.
- If you have large cracks, apply concrete filler or any other damage as recommended on the product. Then, smooth it over using a putty knife and allow it to cure for a few hours.
- Pour a small amount of the sealer into a sprayer or paint tray.
- Apply the sealer in a thin, even coat on the whole concrete surface. A brush should help you to properly apply the sealer along the edges before moving on to the middle of the surface.
- After applying, give the surface time to dry. You should leave it for 24 hours, or you can use a fan to speed up the drying process.
- You can add an extra coat if your sealer says so.

How long does a quality driveway sealer last?
Depending on the quality of the driveway sealer and how it is applied, it can last for at least 10 years. But you will need to properly maintain your driveway, or else it will not last for a long time. A good number of concrete sealers last for at least 8 years; if it’s a film-forming sealer, you should apply it within 3 years.
Which is the best concrete sealer to use; acrylic or epoxy?
Both of these sealers are amazing in performance but have some slight variations. For instance, Acrylic sealers are suitable for both indoors and outdoors, while Epoxy sealers are only ideal for indoors. However, Epoxy sealers are more durable than acrylic sealers. Another difference is that acrylic sealers cure and dry faster than Epoxy sealers. They usually take only 24 hours to dry, while the latter takes more time than that.
What is the best concrete sealer?
The best concrete sealer varies depending on the needs of different surfaces. A sealer that is good for your exterior concrete surface may not be ideal for your interior concrete surface. Also, some people may prefer a sealer with a natural finish, while others prefer one with a gloss or enhanced finish.
Which sealer should I use in a cold or warm climate?
Before choosing a sealer, you should be certain it will work in your area. A sealer that works best in a cold environment may not replicate its performance in a warm climate. So, a siloxane or silane blend is the best sealer for cold surroundings. For the warmer climate, you can choose either acrylic-based sealers or silane/siloxane sealers.
What will happen when I seal the concrete when the temperatures are too hot or too cold?
Extreme temperatures can make the sealer dry very fast or very slowly. Sealing concrete when the temperature is between 50 degrees F and 80 degrees F is recommended. Different sealers have their own minimum and maximum temperatures required for them to dry. The minimum is usually around 40 degrees, and the maximum is 95 degrees. A lower temperature causes the sealer not to dry and won’t last long, while a higher temperature will make the sealer dry unevenly.
