Where 280 Grit Fits
Use 280 between 220 or 240 and 320 or 400. It refines primer without cutting through edges and leaves a uniform scratch for the next step.
Who Uses It
Automotive refinishers, collision shops, furniture and cabinet shops and industrial finishing lines use the Sia 8443.7842.0280 on body filler, primer filler, lacquers and paints. The 81-hole pattern pairs with multi-hole 6 inch pads and dust extraction to keep the surface clear while you sand.
Tips for Longer Disc Life
Use light, even pressure and let the abrasive cut. Keep the pad flat to avoid rounding edges, and clean the surface between grits so loose particles from a coarser step do not leave stray scratches. Change the disc as soon as it stops cutting; a worn disc only polishes and builds heat. Store boxes flat in a dry place so the paper stays flat.
