Abrasive for long-reach sander

225 mm discs for the long-reach wall and ceiling sanders, in Granat on a soft backing and in Granat Net. Grits run P40 through P400 — the coarse end for levelling jointing compound, the fine end for the last pass before paint. The net version is worth the difference on plasterboard. Because the abrasive is an open mesh rather than a disc with holes punched in it, extraction pulls dust through the whole face instead of through a few points, so the surface clogs far more slowly and the disc keeps cutting. On filler, which produces a lot of fine dust fast, that is the difference between changing discs constantly and finishing a ceiling on one.
