Sponge Blasting

Clean, Dry, Low Dust, Reusable Abrasive Blasting


Lepi Enterprises utilizes composite abrasives, incorporating the best abrasives or micro-abrasive particles, within high-performance synthetic sponge. The diverse range of recyclable composites provide superior results for aggressive profiling and abrading or delicate cleaning on highly sensitive substrates. The synthetic sponge captures up to 95% of the contaminants, reducing fugitive emissions through its MicroContainment™ feature.

Recyclers use rapid vibrations to shake and tumble reusable Sponge Media in a spiral path over a series of screens; each size-selected to achieve the desired result. The first coarse screen separates and ejects unwanted, over-sized contaminants (into a waste bucket) that may have been recovered with the blasted Sponge Media. The second screen separates (into another waste bucket):

  • Fine dust
  • Hazardous contaminants (e.g. lead, PCB, asbestos, radioactive particles)
  • Stripped/broken-down coatings
  • Fractured abrasives

Recycled media (typically >95% ) is funneled into a third bucket and ready for reuse – and when merged with a small amount of new media, it creates a consistent “working mix”. The screen opening size of the lower screen and ratio of new media can be adjusted to optimize the balance between acceptable dust levels and maximum media life. Recycle, Reuse, Reduce!
