The 3M Interface Pad is our 1/2-inch thick, medium density foam pad that provides additional surface conformability when used with a 3M Hookit backup pad on a 3M Random Orbital Sander. The additional conformability helps when sanding critical surfaces with fine grade abrasives, after leveling and refining sanding steps are complete, but before final surface finishing steps.

The 3M™ Clean Sanding Interface Pad 28324 is constructed of 1/2" medium density foam with a 3M Clean Sanding hole pattern to add conformability to a 3 x 4 inch Clean Sanding Hookit™ sheet (sold separately) for edgework or contoured surfaces. It mounts a 3 x 4 inch Clean Sanding backup pad on a same size orbital sander. The pad is durable enough for sanding internal corners and edges, but conformable enough to avoid gouging the workpiece, resulting in less re-work. When paired with a Clean Sanding abrasive sheet, the series of uniquely designed holes and channels allows dust to be pulled through the holes and away from the sanding surface. This improves the work environment and prolongs the life of the abrasive.

3M's Clean Sanding dust-management system evacuates dust from the work surface better than 5- or 6-hole products, dramatically increasing disc life and maximizing cut-rate. Optimized with a self-generated vacuum sanding tool fitted with a Clean Sanding filter bag (sold separately), Clean Sanding products allow the vacuum to suction dust from the air and off of the workpiece. This reduces loading of the disc and adds life to the abrasive. Additionally, reducing dust in the air improves working conditions. You can also pair Clean Sanding abrasives with Clean Sanding disc pads for use on a central-vacuum-ready sander.
