The driveway must be dry when it is sprayed, but if, for example, it begins to rain as soon as the spray is applied, the seal will still remain intact.
Question: I know that sealing concrete driveways is recommended. But is this a job I have to do every year? And how long do I have to wait after installation to apply the first coat of sealant? Unlike asphalt, you can start sealing concrete driveways immediately after installation (with asphalt you should wait till 3-6 months after installation). Applying a sealant to this type of driveway every 3-5 years thereafter is good policy, as severe weather breaks down your coat of sealant over time.
