It is a mixture of fine abrasive powder to concrete floors, used to remove marks or stains very penetrated before polishing with LUX POLISH POWDER or use deep cleansing soap. It can be used on any surface made of marble, terrazzo or granzon.
It is highly advisable NOT to use it on natural granite. It is appropriate to remove light marks that are not removable with normal polishing.
Use a floor polishing machine with a brush at low speed, plus you can use disk-type abrasive fibers for its application.
