The performance of any protective coating is highly dependent on the preparation
of the surface, inadequate preparation will lead to premature failure between the
coating and the substrate.
Ripblast use a sonet expandable media, suitable for both steel and alloys with a
cleanliness ranging from SA1 – SA3.

The other main surface quality is the profile achieved which is governed by the
grade of media and the speed of abrasive impact. Thereafter a profile of between
50-75 microns is attained depending upon the type of coating required end use.
Bead Blasting
Another special service that Ripblast provides uses a fully self contained unit,
utilising glass beads as a media. This is excellent especially for requirements
such as removing tooling marks from substrates such as stainless steel. This can
also be used to remove surface imperfections or to provide a more aesthetically
appealing finish. This technique can be used on small intricate items and will not
cause dimensional changes. The final product is foam wrapped so as to avoid further
marking.
