Steady grip. Less than 3.2 kg. High flexibility.

Mirka® Leros-S. Reach Closer.

The Mirka® LEROS-S features the well-known abilities of the LEROS, but in a shorter, even more easily handled length. That makes it perfect for sanding larger areas faster, such as on yachts and boats. The LEROS-S has two dedicated grip points for full control.

Thanks to its lightness, balance and easy manoeuvrability, the LEROS-S makes it possible to sand large areas faster and easier. The large sanding pad with its 5mm orbit works especially well in levelling filler.

It features a highly flexible sanding head to make sanding easier and more ergonomic. A better working position makes sanding more effortless and improves the end result as well as productivity.

Water-Based Polishes

All polishes that Mirka produces are water-based and produced in Finland. There are many benefits of choosing a water-based polishing compound.

  • Effective permanent removal of scratches - Water-based compounds remove scratches permanently. Solvent-based compounds can lose gloss after cleaning the surface with a degreaser and in some cases, they may only temporarily hide the scratches.
  • Safer for the operator - No hazardous chemicals  
  • Sustainable  - Water-based polishes are better for the environment and do not contain benzene.

Solvent-based polishes may be effective in the short run, but they are more damaging and harmful.
