Working on hotel projects can be challenging. This floor had been sealed improperly with a topical coating. It was re coated over without removing the dirt and grease stains, which locked them in. We had to do multiple applications of coating remover while preserving all the surrounding areas. We used a biodegradable citrus smelling remover so as not to disturb the guest too much more than we were. This pic is after it was stripped clean. We finished off with a color enhancing sealer to bring back some of the greens and blues.
Another successful stone job.
