Three (3) 6" metal DiamaPads installed on a 14" velcro pad driver.
Metal Pads.  These pads are very aggressive pads and provide fast stock removal of concrete, terrazzo coatings, sealers and mastics. Metal diamond pads are used when the concrete surface is damaged, has a rough or broom finish, irregular heights, or is coated.  Their grinding performance is smooth and fast.  While they are used to deep grind concrete, remove all types of coatings (hard acrylic or soft mastics), they can also be used to prepare the surface for coating overlays as they leave the pores of the surface open for A+ adhesion and bonding of new coatings or sealers.  They perform like a diamond cup wheel but are 1/3 the weight (less than 8 oz).  With their velcro backing, they install onto velcro pad drivers of the appropriate grinder including handheld and standup machines.

Resin & Semi-Metal Pads.Semi-Metal Pads. These pad are significantly more aggressive and provide longer life than resin pads.  Depending on the initial condition of the floor, Semi-Metal or Transitional (Hybrid) Pads, as they closely look like a resin pads they are generally used before Resin pads or after rough grinding with Metal Pads.  Semi-Metal pads actually start the polishing process as they begin to close the pores of the floor.  They offer all the benefits of a smooth Resin pad but provide longer life and the aggressiveness associated with Metal pads.  After rough grinding with Metal diamond pads the scratch pattern cannot typically be removed by a Resin pad, Semi-Metal pads solve this.


3" Resin Pads being pressed-on to a 14" velcro pad driver.Resin Pads.  Are used after the surface has been totally cleaned and smooth.  Depending on the initial condition of the floor, the Metal or Semi-Metal Pads may first have to be used.  Resin pads are designed to abrade the scratches left from Semi-Metal Pads.  With the diamonds exposed on the surface of a resin pad, deep scratches are quickly sanded away by the diamonds that are suspended in the plastic matrix.  The plastic matrix is what gives the resin pads their less aggressive nature or polishing capability.

While it is true you can hone with a coarse resin pad, they are not really designed for this task (or step) as they will quickly wear under this circumstance.  As you progress through the series of Resin pads - increasing to the finer grits - the pores of the concrete are progressively closed to ultimately result in a mirror-like finish.  The multi-step process provides you with the flexibility to choose how many steps you want to achieve the desired finish.

Typically, you start with a 50 coarse grit and proceed as you would with your regular floor cleaning routine.  After a few passes, you progress to the next grit.  By the time you reach the end of the process, the floor will transform into a beautiful, smooth and polished surface.  The multi-step process provides the flexibility for you to decide how many steps you want.  Depending on the type of floor and its initial condition, as well as the machine's down pressure and speed, the number of passes you make with each grit depends on the level of gloss you wish to obtain.
