MICRO-MESH is a unique cushioned abrasive that produces a very fine and uniform scratch pattern. The grit range is from 1500, which is close in scale to Klingspor's 600 grit, up to 12,000. The 12,000 will leave a scratch pattern undetectable to the human eye. MICRO-MESH abrasives can polish to a high reflective state or leave a matte or satin finish depending on where you stop using the series. MICRO-MESH can be used on either bare wood or wood finishes, wet or dry and they last 5 times longer than ordinary sandpaper.
