What happens if it rains after applying the sealer?

It is best to apply sealer on a day with moderate temperatures and no rain in the forecast.

The sealer typically becomes dry to the touch within 15 minutes and requires up to 24 hours to fully cure. Light rain after the surface has dried is usually not a problem. Moderate rain a few hours after application is often tolerable.

However, heavy rain within the first 24 hours may affect the finish and cause a cloudy or hazy appearance.

If this occurs, the issue can usually be corrected with a light application of xylene, as described above.
