Grit blasting is an inexpensive and reliable pre-treatment method with only one downside: it generates quite a lot of dust. When dust poses a problem, it is better to opt for a dust-free method such as dry-ice blasting, vacuum blasting or sponge blasting. If grit blasting can cause damage to the object, even when the finest grain size is used, soda blasting is a better option. For the removal of grease, bitumen and suchlike, dry-ice blasting is the best method. DCS is highly proficient in all these techniques.
