▶ Sanding
Sanding discs range in grit from 16 (very
course) to 180 (very fine). They also vary
in size and spacing of grit.
OPEN COAT (type H) is used for soft ma-
terials and on paint and varnish, CLOSED
COAT (type K) is used for metal, hard-
wood, stone, marble and other materi-
als. To obtain best results, select sanding
discs carefully. Many jobs require the use
of several grit sizes and at times both open
coat and closed coat discs are required to
complete the job. See chart for applica-
tion examples.
1. Allow the tool to reach full speed be-
fore touching the tool to the work sur-
face.
2. Apply minimum pressure to the work
surface, allowing the tool to operate
at high speed. Sanding rate is greatest
when the tool operates at high speed.
To remove paint and to smooth surface irregularities.

3. Maintain a 10° to 15° angle between
the tool and work surface, (Fig. 28).
4. Continuously move the tool at a moder-
ate speed to avoid creating gouges in
the work surface.
5. Remove the tool from work surface be-
fore turning tool off. Allow the tool to
stop rotating before laying it down.
Tip: Guide the disc with crisscross strokes.
Do not use a circular motion as this makes
swirl marks.
