Different types of decorative concrete involve different processes so timing will vary. However you should normally allow between 8 to 20 days for us to undertake and complete your job.
We have had plenty of customers who did not want to wait that long and drive on the concrete 3 days after it was placed without having any problems. So it can be done with small cars and light trucks but we recommend 7 days.The full 28 days for heavy equipment or large heavy trucks(ex: a concrete truck).
