3M Marine Prop Polishing Disc
Marine Disc Holder
for removal of heavy marine fouling (barnacles, tubeworms, etc.) as
well as calcium and basal plate deposits from ship propellers.
Propeller surfaces roughened due to age, fouling, and electrolytic
action can be polished to a high luster finish. In severe cases
#5 discs are used to smooth the surface, followed by polishing with
#3 density discs to restore a like-new condition (a Rubert Grade of
A or B). Especially effective when used in conjunction with
the Rubert Roughness Comparator Scale enabling the operator to test
the finish before, during and after polishing to attain the smoothest
finish and accurately assess the improvement. Also ideal for
removing calcium deposits, black algae and for cleaning cement piling,
and welds in steel pipelines, prior to inspection.
