Onyx® is usually able to be applied 8 months out of the year. We just completed a project this last October in Oklahoma. We were fortunate the weather was above 50 degrees with a slight wind so that the Onyx® would dry quickly and get commuters back on the road.
We've applied Onyx® with the city of Norman, OK for the past 4 years. They have a very aggressive pavement preservation plan and we are happy to help! See more about how Onyx® can help your town at https://www.hallbros.net/onyx
