After letting it sit for 24 hours, peel it up and look for any condensation on the underside of the plastic or look for a dark spot on the surface of the concrete. Water on the underside of the plastic or a dark spot on the concrete is created from moisture. If none exists, then you should be fine.

What happens if I seal my concrete too soon?

If you were to seal the concrete any sooner, it would create a barrier and prevent the excess moisture from evaporating correctly. As a result, the newly poured concrete driveway would not be as strong as it should be. In addition, the concrete would be more prone to breaking and cracking.

What is the lowest temperature you can seal concrete?

Generally, 50 degrees F (10 C) is the accepted minimum temperature when applying most film-forming concrete sealers and coatings. That number pertains to the temperature of the sealer, as well as the temperature of the air and the surface being treated.

How many coats of concrete sealer should I use?

Concrete sealers are best applied in two thin coats. The first coat of sealer acts like a primer. Most of it will disappear into the concrete surface, and the concrete will probably look fairly unattractive after the first coat.

When's the best time to seal your driveway?

It's best to seal your driveway in the fall or the spring because the temperatures tend to be more moderate. In order to put seal coating on, the outside temperatures need to be above 50 degrees Fahrenheit. In addition, the weather needs to be free of heavy rain for 24 hours.

Can you seal coat in cold weather?

Temperatures below 50 degrees Fahrenheit are too cold to apply sealcoat. Furthermore, if the low temperatures fall to freezing or below while the coating dries, water in the sealcoat material could freeze, leading to the finished product separating and peeling.

Why does concrete sealer peel?

Peeling/Flaking: Concrete sealers peel and flake when first applied if the application was too heavily applied or there are too many layers of sealer on top of each other.

The sealer was not completely dry when an additional coat was applied. It's important to allow the sealer to dry completely clear, before applying an additional coat.
