7. Selection of abrasive
Media nr. 2
Is often used when the surface is only subsequently sealed.
− creates fine profiles, e.g. on vacuum concrete and non-glazed tiles
− removes thin layers of rust on steel surfaces
− removes thin layers of paint
Media nr. 3
− creates a fine to medium texture on concrete.
− removes glazing from tiles prior to subsequently coating with antiskid floor sealings
− removes old impregnations and coatings about 1 mm thick
Media nr. 4
Standard abrasive, suitable for about 50-60 % of all applications. Creates a medium profile
on concrete. Fulfils the same purpose as Media No. 3 when a higher speed of the machine is
required, e.g. on asphalt, in order to keep the thermal load low.
− removes laitance from new concrete
− roughening of smooth concrete or natural stone
− removes coatings with a thickness of 1-3 mm
− cleaning of steel surfaces
Media nr. 5
This media is used to create a coarse profile or to increase the work speed in the case of
surfaces hard to treat.
− removes sediments on concrete prior to coating
− removes thick paint coatings or rust from steel surfaces, bridges, tanks, etc.
− removes flexible coatings on parking house decks
− removes road markings and retexturing of asphalt and concrete roads
Media nr. 8
Only as an addition to Media No. 3, No. 4 and No. 5 with maximum 30% content.
Media No. 8 should never be used without blending since otherwise the wear in the machine
as a whole would increase disproportionately.
− removes polyurethane coatings
− removes adhesive remnants
− removes rubber deposits
− penetrates coatings hard to remove
− also suitable to be used on steel for extraordinary roughness
