We had a new driveway put in about a month ago. The concrete itself had color mixed in, a light beige. After it was poured, it had a light coating of a darker colored "release" powder put over it, and I believe it was there as the stamping was happening. After the concrete was cured, the "release" powder was pressure-washed off. The "release" power was from Davis, and I believe it was just a different color of powder that is used to color concrete. After several days, a seal coat of Davis W-1000 clear concrete coating was applied (2 coats).
After 2 weeks, we parked a car overnight on the driveway, and the tires left their treadmarks when the vehicle was moved the next day. The seal cote AND the release color peeled away, revealing the lighter concrete color. A few nights later, we parked a different car in a different part of the driveway and the same thing happened.
Any ideas why this is happening and what can be done to prevent further damage ?
