Description
The Sia interface pad sits between the sander backing pad and the sanding disc to change how the disc meets the surface. At 6 inches across and 1/8 inch thick in a firm density, it adds a layer of controlled give that helps the abrasive follow gentle contours while still cutting flat. The universal hole pattern lines up with common dust-extraction disc layouts so suction stays clear.
Where the Sia interface pad is used
Stone fabricators, solid-surface shops, automotive refinishers, and woodworkers reach for an interface pad when a hard backing alone leaves swirl marks or digs edges. The cushion lets a hook-and-loop disc wrap slightly over rounded profiles and absorbs abrupt machine movement, which protects both the finish and the operator’s wrists on long sanding sessions. It works on random-orbital and rotary sanders that take 6 inch hook-and-loop discs. On contoured stone edges and shaped solid-surface work, that extra conformability is the difference between a uniform scratch pattern and visible flat spots.
How the Sia interface pad performs
The firm grade favors flatter work and aggressive stock removal, where a softer pad would let the disc roll over and round an edge you wanted to keep crisp. Foam interface pads are wear items: they compress and tear over time, so keeping spares means a worn pad never forces a compromise on finish quality. Match the hole pattern to your disc and backing plate for clean dust pickup.
