Fred, Very timely post! We just paved our driveway this summer and Iâve been asked several times by folks in the neighborhood when we should seal it. The company I work for has an entire paving division so I asked the experts and they all agreed that you need to wait at least 90 days.
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.
