Sandblasting
Sandblasting is a special procedure for freeing various materials
(metal, wood, glass...) from impurities and other substances.
This prepares the base for the application of protective coatings, but also enables aesthetic decoration of the material (engraving).
When it comes to sandblasting, quartz sand is used, namely granulation: from 0.3 to 0.8 mm, from 0.8 to 1.2 mm and from 1.0 to 2.0 mm
(most often when it comes to sandblasting bridges).
