Notes on blasting
It is advisable to hold the blasting gun at a distance of
approx. 40 - 60 mm from the workpiece and at an angle of 45 - 60°.
The gun should be passed evenly over larger areas in order to avoid
cloud formation. Under certain circumstances, finally blast the entire
surface again, but with a greater gun distance.
Fine profiling and sharp edges must only be blasted with fine grits
and at low pressure.
If surface improvement is to be achieved, work must be performed
several times with different grit sizes (from coarse to fine). The blast-
ing shots MK 40/90, followed by MK 90/150 and finally MK 245 are
recommended for this purpose. Subsequent blasting with GPF fine
glass beads results in a silk gloss.
Restoration work is mainly performed at low pressure with the use of
glass beads, high-grade corundum and walnut shells.
