How to polish marble

1, Coarse grinding:

Using 50#, 150#, 300#, 500# resin diamond hard grinding block for coarse grinding.(Do not use flexible wet polishing pads for coarse grinding, it will wave, to affect the flatness.)

When coarse grinding, add much water but not too much. Completely absorb water after each step polishing pads finishing grinding, check the deep scratch left whether 50# polishing pads can remove.

2, Medium grinding:

Use 800#, 1000#, 2000# diamond flexible wet polishing pads. Medium grinding accounts for 35% the overall grinding time. After 800# medium grinding, it begin to bright, when 2000# grinding, glossiness is up to 50 degree.

3, Fine grinding:

Use 3000# diamondflexible wet polishing pads, spraying A2 by ion exchange. Fine grinding accounts for 20% total grinding time. The gloss rises after fine grinding, and improving the density of marble. It is a solid foundation for polishing agent(NO2 Q5 mirror repair agent), enhancing polishing material adhesion.
