Chemstone umber at 7:1 - sprayed it on and kept spraying as it dried. Kept it wet with hot acid for about an hour & a half before neutralizeing and rinsing. Unbelievable color for that dilution. Sealed next day, sprayed two coats CSS @ 3:1, then final coat @ 1:1 w/ sharkgrip - sprayed and backrolled. Surface was 60 days old, it was finished with power trowel & there were power trowel marks throughout surface - it needed to be kneeboarded one last time (note close up of one of the worst areas).
Glare from sunlight through the building made wide-angle shots impossible because of the glare off the sealer. Will get shots posted after they open, this is a winery's retail tasting outlet / bar.
