Grout’s drying time depends on several factors, including temperature, humidity, and grout type. In general, traditional sanded grout takes 24-48 hours to set and 7 days to fully cure. Unsanded grout, suitable for smaller joints, dries faster, typically requiring only 12-24 hours to set and 3 days to cure. Rapid-setting grouts accelerate the process, allowing foot traffic in as little as 4-8 hours. However, full curing still takes several days. It’s crucial to follow manufacturer’s instructions and avoid excessive moisture during the curing period to ensure optimal grout performance and prevent cracking or discoloration.
