These interface pads are for both mesh and traditional abrasives. By using an interface pad, you will get a softer sanding result for sanding curves. The interface pad is placed between the backing pad and the abrasive.
The 10mm thick multi interface pad is used in combination with hook & loop sanding discs for sanding rounded surfaces and contours, ideal for Mirka's mesh abrasives.
