Sealing Concrete

The best way to protect your decorative concrete surface is to have it coated with a high-quality sealer.

Why do I need to seal my surface?

Sealing a decorative concrete surface is critical no matter where you live, but it’s especially important for outdoor surfaces that see lots of rain, hail, and snow—especially if snow sits on it for long periods of time. In addition to protecting your surface from the elements, SUNDEK sealers can protect from everyday wear and tear, oil spills, chemical spills, and more.

Can I apply sealer myself?

While it might be tempting to try to apply a sealer yourself, we recommend having a professional do it for you, as the conditions need to be practically perfect to do it. One of the most common issues during the application process is applying too much which causes bubbling. It’s also critical to apply the sealer in the right conditions. Outdoor temperatures that are either too hot or too cold can also cause bubbling. Additionally, it’s important to apply the sealer an appropriate amount of time after the decorative concrete coating was applied. If you do it too soon, your surface may end up looking discolored. Since we’re familiar with these nuances, we can make sure your sealer gets applied properly.

How often do I need to reseal my surface?

The frequency for reapplication depends on where your surface is located and how it’s used. For example, an infrequently used walkway that’s protected from the elements will need to be resealed less often than a driveway that has snow sitting on its surface for two months a year. At SUNDEK of Washington, we’ve been working with decorative concrete for decades in the Washington D.C., Maryland, Delaware, and Virginia areas. Our experience means we’re well versed in the needs of decorative concrete in this region, so we can guide you through the process of determining a resealing schedule.
