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 marbles with No. 24.

Instructions for Use:

• Nephrite abrasive stones are used not only for grinding and cleaning but also for dry polishing.
• Dry polishing starts from No. 12 for mosaics or No. 24 for marbles.
• Continue to No. 36 for mosaics and No. 60 for marbles.
• After No. 60, proceed to No. 100, No. 230, No. 450, No. 560, and then continue with oxalic.
• It is obvious that a very good sweep is needed between the numbers.
• Oxalic is worked with a machine brush, synthetic or with steel wool No. 2, in small lumps at intervals that are moistened with a little water to turn into mud.
• After the entire floor has been covered, it is rinsed very well.
• Then apply the MAR polish, which is worked either with a synthetic or hair machine brush or with 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 cleaner on polished marble other than plain clean water.
