If you want to sand down wood or wooden materials, use red:Wood sanding sheets. They are available in grits of 40 to 400. Rule of thumb: use a grit that is twice as fine for each subsequent work step, example: 40 80 180. white:Paint sanding sheets are available for paint, varnish, filler or roughcast and black:Stone sanding sheets for stone, marble, granite, glass or stove enamel.

You can also use polishing fleeces for your BOSCH Delta Sander. They consist of a loose woven fabric made of plastic fibres, into which the coated abrasive is incorporated. In medium to coarse grit, they are suitable for coarse dirt, for removing rust or structuring. In fine grit, they are suitable for fine sanding painted surfaces.
