(See 8.3.21 of American National Standard Z9.1-1951.)sp.info What should the profile depth be for abrasive blasting?Generally, the correct profile depth will be 25-30% of the dry film thickness of the total coating system. For most industrial coatings, the typical steel profile is between 2-3 mils, not normally exceeding 5 mils. Knowing the surface characteristics and the profile depth you need to achieve, you are ready to select your abrasive.See all results for this questionsp.info What's the depth profile of a garnet Blaster?Coatings adhere poorly to hard, flat surfaces, so the blaster is required to develop a pattern of indentations that the coating can anchor to, aka the anchor pattern. An 80-mesh garnet particle leaves up to 3.6 mil depth profile in steel. 2. Peak 4. ValleySee all results for this question
Check the manufacturer’s data sheets for the most current and accurate information.
