Station 3 Lofts
The photos above and below show several acid-stained concrete floors in a luxury loft condominium building in Royal Oak, Michigan. We didn't do the original acid-staining in these units, but we were asked to refurbish the floors periodically when a tenant moved out. These particular five floors were cleaned, touched up with stain and then re-sealed.
The four photos below are examples of the type of damage done to the acid-stained concrete floors by tenants. In the first two photos below, carpet or matting with a rubber backing was placed on the floor for an extended period of time. When the coverings were removed, they pulled the sealer and stain right off the concrete.
The next two photos also show damage caused by carpet or matting with a rubber backing. In these two instances, however, rather than removing the sealer and stain from the concrete, the black rubber came loose and stuck to the concrete.
Repairing acid-stained concrete can be done but is not easy. It takes a thorough knowledge of sealers and chemical stripping agents, and training in faux finishing. Our best advice is that if you have a new acid-stained concrete floors, do not place anything on it made of plastic or rubber, or with a tacky backing.
