What is the technology of sandblasting and how does it work?
Answer from: Olga Turabova:
The essence of technology is to expel the abrasive (sand, apricot kernels...) under pressure of air or water (or other inexpensive substances). Target "peel off" unnecessary layer (paint, primer...). With water, there is less dust. There are available nozzles on the high pressure machine. Sand and air technology, the more "budget" and affordable. But dusty.
