Interface MIRKA®

The Mirka interface pad is a soft pad placed between the sander's backing pad and the abrasive disc. It adds flexibility to the pad: the disc follows curves and irregular surfaces better, pressure is spread and the finish becomes more even.

Available sizes

• 77 mm: 5 mm thick, 6 holes.
• 125 mm: 5 or 10 mm, 33 or 44 holes.
• 150 mm: 5 or 10 mm, 67 holes.
• 175 mm: 5 mm, 37 holes.
• 200 mm: 7 mm, 89 holes.
• 225 mm: 17 or 22 mm, 8+1 holes, for wall and ceiling sanders.

What an interface pad is for

A sander pad is relatively rigid. On a curved surface, it bears on only part of the disc, which heats up, wears locally and leaves marks. The interface absorbs these differences: the disc stays in contact over its whole surface.

It also protects the pad. A pad's hooks wear with each disc change; the inexpensive interface takes this wear instead.

Choosing the thickness

5 mm: moderate flexibility, to keep flatness while softening the sanding. 10 mm: marked flexibility, for curved shapes and finishing. The thicker the interface, the more it conforms to shapes, and the less suitable it is for levelling a flat surface.

Match the holes

For extraction to work, the interface holes must match those of the pad and the disc. A wrongly perforated interface blocks extraction: dust stays under the disc, clogs it and scratches the part.
