501-36-31 Paint - General Information 501-36-31 DESCRIPTION AND OPERATION During sanding, material is mechanically removed from a surface. In the paint shop, carborundum or silicon carbide abrasive on a substrate of paper or cloth are the most common sanding materials used. Carborundum is a very hard mineral consisting mostly of aluminum oxide. During use carborundum becomes blunt and wears away. Application Working area Body work, corrosion Equalizing paint system damage transition Stopper Rough sand Fine sand Spray stopper Rough sand Fine sand Filler sanding work Filler fine sand Top coat Old paint Touch-up paint surfaces Paint damage Sanding out faults Soft Pads are recommended for manual refinishing of contours, curves and difficult to reach areas. On a Soft Pad the abrasive is found on a coarse structured fleece. Because of this, it is very flexible, does not kink and does not slip in the hand. This enables a fine and even finish to be achieved. Silicon carbide has a very high degree of hardness, but is more brittle than carborundum. When silicon carbide is used, the mineral grains break. New long and pointed profiles are formed. Use of the correct sanding paper depends on the application, the substrates and the tools used. The following table can be used as a guideline, but the recommendations of the supplier of the auxiliary materials and additive materials must be followed.
