Generally, you can use your resurfaced concrete or asphalt within 24 to 48 hours. However, this timeline can vary depending on several factors, including the materials used in the resurfacing process and the prevailing weather conditions. For instance, cooler temperatures or high humidity can extend the curing time, while warmer, drier weather may allow quicker usage. It’s always best to consult your contractor for the most accurate guidance tailored to your situation.
