rock descriptions are medium-grained, hornblende-biotite schist, or fine- to medium-grained, garnetiferous, muscovite-chlorite-feldspar-quartz gneiss. The above classification can be abbreviated by the deletion of mineral names from the left to right as desired. The mineral type immediately preceding the rock name is the most diagnostic.

This ensures a smooth sanding. Choose quality products - so you avoid irregularities in the paper that can damage the substrate. How closely a product is coated - i.e. how many sand grains there are per m2 varies. Typically 50 to 75% of the surface is covered with grain. The coarse grit sizes are usually scattered more open than the finer.
