Full surface dust extraction thanks to open net backing

Grit on a cloth / paper backing

Grit on a cloth or paper backing is embedded in binder resin on the whole surface, and dust extraction is enabled by punched holes.

Grit on a net backing

A net backing, consisting of a polyester fibre, is coated using a modern specific manufacturing procedure. Thanks to a sophisticated process, only the top fibre of the net is coated with grit. The inner, functional structure and the back of the abrasive with the siafast fastening loops remain free of grit.

This precise grit coating ensures full surface dust extraction for a dust free work environment and maximum removal rate.
