Covered in 2 coats. Approx 650 sq ft. Half of that had not been resealed in 6+ years which really soaked it up. Half was a new pour approx 30 days old. 3 days between coats. Total product used approx 7.5 gallons.
Had a couple of questions initially and support was very responsive. Plan to use the remaining on resealing front entry flag stones.
