I have recently gained access to a high quality sandblaster, but I really don't know much about the process. I have a few questions.
1) Do I have to use sand for the blaster, or can I use something else in it? I've heard that you can't use soda because of the way it feeds into the system? 2) I want to use soda because it's less abrasive, but I read that soda will not remove the rust. I definitely need to remove the rust. Which type of medium is best for this? 3) Can you give me any general advantages/disadvantages of soda, sand, walnut, or plastic? Any others that I don't know about? Any advice/suggestions/info you could provide would be helpful. Nobody around really does this, so farming it out isn't a viable option. It's either this or the long way, and I'd really like to blast if I can. Thanks for your help, guys. |

If your sandblaster is a preasurized type or just a bucket type, the sand of choice is Black Beauty. It comes in different grain size and is made of compresed cole. Once the BB hits the sheet metal, it becomes finer. A sandbalsted surface will need some glasing putty because of the rough texture. BB is very forgiving and will give you the time to blast frequently on the same spot without eating through your thin guage metal. The easiest place to find it is at an equipment rental place, Sunbelt Rental, United Rental, RSC, that rents sand blasting equipment. If you want the rust to go away, BB is the way ta gooooo; or use the alternative method (IMG:http://www.914world.com/bbs2/html/emoticons/sawzall-smiley.gif) !!!!!
