The growing need to preserve our cultural heritage is causing a rise in the demand for increasingly accurate cleaning techniques, featuring high selectivity and low impact.


Studies shown indeed that Er:YAG laser exposure on a surface dampened with a liquid containing –OH groups effectively removes old varnish and other encrustations without inducing unwanted chemical or physical changes on the original surface.

For this reason, Light Brush 2 is particularly suitable for the removal of overpaintings and varnishes from wall and easel paintings.

Light Brush 2 is an innovative tool for restorers thanks to variable energy emission from 50mJ to 500mJ and to the pulse duration optimised for the cleaning of Cultural Heritage.


  • Light and easy-to-use system with articulated arm
  • Efficient on the removal of yellow varnishes and overpaintings
