While these are excellent sanding sponges for freehand use, they also have a grip backing that allows them to be mounted on the hook facing of a 3" × 4" Mirka orbital sander platen or Mirka hand-sanding pad.
Suitable for use on softwoods and on curved surfaces, the sponges have a 1/2" (12mm) thick backing made of low-density polyurethane foam. The pliable, durable foam conforms to pronounced contours to maintain even contact with the work while cushioning your fingertips so the sponges are comfortable to use for long periods.
They come in nine grits from 36x to 320x. Made in Finland.
Press this Mirka 3" × 4" × 1/2" grip-backed sanding sponge directly onto the work by hand, or use the grip backing to mount it on a Mirka orbital sander platen or hand-sanding pad.
It's a flexible foam pad with an abrasive surface that conforms to the work, suited to softwoods and more pronounced curves than a rigid sanding block can follow.
This low-density sponge comes in nine grits, from 36x for aggressive stock removal to 320x for a fine finish.
This version uses a softer, low-density foam backing that follows pronounced contours, while the higher-density versions suit flatter, harder surfaces.
