Polyester-based stones for grinding building materials such as marble, mosaics, concrete, natural stones, in construction.

For mosaics and concrete, grinding starts with No 12, while for marble with No 24.

Instructions for Use:

• Kidney stones for polishing are used not only for grinding and cleaning but also for dry polishing.
• Dry polishing starts from No 12 for mosaics or number 24 for marble.
• They continue with No 36 for mosaics and No 60 for marble.
• After No 60, proceed to No 100, No 230, No 450, No 560, and then continue with oxalic acid.
• It is self-evident that very good sweeping is needed between the numbers.
• Oxalic acid is worked with a synthetic machine brush or steel wool No 2 in small tufts at intervals that are wetted with a little water to become like mud.
• After the entire floor is passed, it is washed very well and then we apply the MAR polish, which is worked either with a synthetic machine brush, a bristle brush, or steel wool No 2.
• Maintenance is done with AR 247 polish once a week in a bucket of water.
• It is forbidden to use any other cleaner on polished marble apart from plain clean water.
