Sponge blasting

Safe for humans, friendly to the environment!

This method is also used for cleaning of sensitive surfaces requiring special cleaning  treatment in order to minimize the wear on the cleaned surface. It is preferred in cases where hydro blasting or abrasive blasting is prohibited (hydraulics, electronics, bearings etc.) or when degreasing without water or liquid detergents needs to be done.

The reasons that this relatively new cleaning technology is particularly friendly to humans and the environment are:

  • it does not alter the metal surface, therefore no harmful metal residues are produced,
  • its low rebound – low airborne dust abrasive method virtually eliminates the dust particles produced by sand blasting, since it reduces them by over 90%, thus enabling the cleaner to work wearing regular instead of protective clothing,
  • its low ricochet makes it possible for other cleaning or repair services to be conducted in the same area simultaneously, thus reducing the total maintenance time of the asset,
  •  it allows selective striping of coatings and removal of contaminants while eliminating damage to adjacent surfaces and surrounding coatings, and
  • since it uses composite abrasives made of sponge media of various sizes and degrees of roughness (instead of sand) it allows their collection and removal after the cleaning process, and also their subsequent multiple use, thus eliminating the traditional waste disposal and pollution of the sea water and nearby areas.

Residuals of cleaning methods such as sand blasting, as per EU regulations, must be collected by specially authorized waste management companies following specific disposal procedures.

In addition to the heavy duty cleanings in shipping and industrial land installations, this dry cleaning method (like the dry ice blasting method) is used in very sensitive surfaces requiring maximum care during their cleaning, like wood surfaces in luxury yachts (for example teak wood which has been specially treated with appropriate solutions for decades prior to its use for the construction of the yacht), external surfaces of luxury yachts made of aluminum, carbon fiber or polymers, national monuments, statues or archeological objects and buildings with “national heritage” characteristics and other valuables made of marble, bronze, stone etc.
