Twister Diamond Floor Pads are a revolutionary eco friendly cleaning system incorporating microscopic diamonds which restore, clean and polish the floor mechanically instead of using chemicals. The 16" Yellow Diamond Twister Pad is Step 2 of the Twister method which leaves a surface well prepared for the final maintenance step by using a progrssively finer grit than step 2. The twister system is suitable for most common surfaces including terrrazo, natural stone, concrete, vinyl and epoxy and should be used on a slow speed rotary flooor machine (180-200 rpm).
