Abrasives

Abrasives are used during the repair and painting process to smooth out uneven surfaces or to create a rougher surface texture to ensure good adhesion, or both.

Most abrasives come in discs, strips, sheets and belts. Other shapes are also manufactured for specialist tools, for difficult to reach areas or when only a very small area needs to be sanded.

Automotive abrasives have many names:

Abrasives have different fixing methods:

Abrasives have a coarseness rating which is a number defining how coarse or fine the abrasive is – the larger the number, the finer the grit. The coarseness of abrasives used in body repair work ranges from 40 to 2500.

Tips:

The table below shows which coarseness is generally used on the following surfaces (please refer to the Technical Data Sheet for the correct grit to use):

Other grits are available but not widely used in body repair work.

Most manufacturers of preparation and painting systems will specify the correct abrasive grit to be used in their Technical Data Sheets.

Tips:
Scotchbrite is widely used these days. It is a very fine, webbed, abrasive pad for preparing areas during the painting process that you need to blow or blend in to ensure you have good adhesion. It is also used for sanding awkward areas which do not need any filling or priming.
