Weha 7 Step ES Diamond Polishing Pads are made with non marking, no dye, white resin with high concentration diamonds. This allows the Weha ES Diamond Polishing pads to bite into the dense quartz and polish very quickly but not burn the resin in the engineered stone. With 7 steps, this makes puts the traditional 7 step system in a league of its own. For ES material but outstanding polishing on granite, marble, and concrete counter tops. Depending on the type of ES and the color, 7 steps may not need to be used.
