Requirements
Your work area must be large enough that the airborne sand won’t damage other surfaces or get into other items or you must have an enclosed work area.

Air Compressor must be larger then expected. Small and Medium sized compressors under 6HP probably won’t be able to serve a blaster larger then a handheld model.

Blasting Media should be matched to the material you will be working on. Sand is good for steel and cast iron but plastic media will provided better results on soft metals and fiberglass.

Protective Clothing is a must not specifically because the high pressure sand coming out will come in contact with you but a protective hood or very good tight sealing goggles are necessary to protect your eyes and long sleeves and a taped or closed neck line will definitely be a needed if you are not working in an enclosure. You will basically be working in a miniature sand storm.
