- Very five or delicate papers, utilized by wood-finishers from 00000000, or 8/0, to 00, or 2/0
- Medium sizes, regularly utilized by carpenters: 0, or 1/0, 1/2, 1, 1 percent, 2
- Very coarse papers, all the more normally utilized on sanding machines for quick cutting: 2 ½, 3, 3 ½, 4
Sizes better than 8/0 sandpaper are made by certain makers, however are not usually found available. Lamentably, the extents of sandpaper are not totally institutionalized, and one maker’s sizes may not relate precisely with those of another.

The end grain of wood must be sanded across. A cautious investigation of wood structure with a magnifier shows that the strands are organized like equal cylinders the long way of the grain. These strands are damaged, torn, or slice through by the sharp edges of the sand coarseness if the strokes are some other way than the long way of the grain.
Resending with the grain in the best possible manner would not effortlessly expel scratches. Such wounds ought to be Schuurblok out, and after all scratches have vanished, the surface ought to be sanded, pushing the sandpaper longwise of the grain of the wood with the fitting instruments, regardless of whether they are exactness estimations devices or explicit sanding apparatuses. Squares for holding sandpaper all together that more noteworthy weight might be applied are utilized in each completing room. The size, weight, and covering for the squares rely on the sort of work being finished. For enormous surfaces a fairly huge overwhelming square has a few favorable circumstances.

For the first sanding with coarse sandpaper some laborers incline toward a hard level square with almost no covering. Sandpaper over a hard square without covering, or with small covering, will remove the .high spots better and help to decrease the to some degree unpredictable surface to a more genuine, leveler, or plane surface.
