Sand blast beads fine – Grade AG
Blasting material normally comes in different grit sizes. The higher the grit size is numerically, the finer the particle size. The lower the grit size, the coarser the particle size. Lower grit sizes are more aggressive, in general, than higher grit sizes of the same blasting material. For example, Aluminum Oxide 60 grit is more aggressive than Aluminum Oxide 120 grit. It’s important to use the correct material in the correct grit size to properly do your work.
Again, if you aren’t sure about what blasting material to use for your type of work, get a recommendation from an expert. It will save you a lot of time, frustration, and money versus trying to guess, if you are not sure.
