The Pyramid Pie Floor Abrasives are the most advanced set of diamond abrasives available for restoration and maintenance of stone floors. Pyramid Pie Floor Abrasives will remove scratches, etch marks, wear patterns and repolish worn marble, terrazzo and agglomerate. Special resin compounds and a radius leading edge result in better performance and longer life. Pyramid Pie Floor Abrasives normally do not require the use of messy acids and powders to achieve a final polish as with other floor abrasive systems. Pyramids are available in 8 grits (60 grit - 3500 grit) providing the stone technician with a wide range of finishes.
