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

Follow the usage instructions:

• For mosaics and concrete, grinding starts with No 12.
• For marbles, grinding begins with No 24.

The kidney-shaped grinding stones are also used for dry polishing:

• Dry polish for mosaics starts from No 12.
• Dry polish for marbles begins with No 24.
• Continue with No 36 for mosaics and No 60 for marbles.
• After No 60, proceed to No 100, No 230, No 450, No 560, and then with oxalic.

Between numbers, very good cleaning is required. The oxalic is worked with a synthetic machine brush or with steel wool No 2, in small batches with a little water.

After completing the process, rinse the floor very well and then apply MAR polish.

Maintenance is done with AR 247 polish once a week in a bucket of water.

The use of any other cleaner, except simple clean water, on polished marble is prohibited.
