Sanding

Car Sanding Paper

Perfect sanding of vehicle body parts, old car paint layers and all other surfaces requires all-round expertise. Picking the right sandpaper is a crucial step. Sandpaper consists of fine particles from either natural or synthetic sources. The particles (also known as grains or grit) are sifted through screens and sorted by size before being bonded with adhesive to a paper, sponge, or cloth-type backing. Start by choosing the right sandpaper grit and type. Keep in mind: The higher the number, the smaller the grains and the finer the sandpaper grit. Lower numbers indicate larger grains and overall coarser sandpaper.

  1. Select the right size of sandpaper grit
  2. Choose the appropriate coarseness
  3. Consider the best type of grit to choose
  4. Find the right tool (machine sanding or manual sanding systems)

Coarse Sanding

Coarse sanding is the most basic sanding process used for sanding rough surfaces after joining components or as preparation for welding work. 

  • Removal of adhesive residues and films
  • Sanding rust, weld seams, stone chips, vehicle body parts and car paint
  • Cutting vehicle body parts

Repair Sanding

Professional repair sanding involves rebuilding the various layer thicknesses using suitable filling and sanding methods. Removal of car paint, scratches, dents, fine sanding of filler etc. 

Car Paint Sanding

Lacquer sanding can be done for various reasons:

  • Dust inclusions
  • Paint runs and orange-peel effect
  • Sanding (scuffing) of conventional car paints and clear coats

Machine and Hand Sanding

A sander is a power tool used to smooth surfaces by abrasion with sandpaper. Sander machines have a means to attach the sandpaper. Hand sanding is a little slower than power sanding. However, hand sanding blocks and abrasives are commonly used to sand a wide range of surfaces quickly and efficiently.

Sanding Belts

Belt sanders are commonly used for sanding very rough surfaces, leveling surfaces and freehand rounding and shaping.

Narrow Belt Sanding

Narrow sanding belts are suitable for grinding, sanding and polishing of wood, metal, glass, stone, marble and granite.
