7. Selection of abrasive
The Blastrac blast cleaning machines are designed and built to operate with
Blastrac abrasive .
Blastrac abrasive has a very high quality and has the rebouncing ability required for the efficient use of the
machine. The selection of abrasive is very important since this is the material to carry out the surface
treatment.
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 Abrasive S330
 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 Abrasive S390
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 Abrasive S460
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 Abrasive SG25
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
Please take into account that the use of incorrect abrasive increases wear.
Our service engineers have the experience to select the appropriate abrasive for the
individual cases of application.
Please consult your local
Blastrac customer service department if you have any
questions about the selection of the best abrasive for your blast cleaning work.
