  • Outdoor sandblasting- your choice of media

    Guys, I wonder what media you actually use with your pressure pots when blasting outdoors. Do you even attempt to collect it for reusing?

    Thank you.

    P.S. I'm perfectly aware of all the health hazards, so please let's not discuss silicosis, etc. in this thread. I want to know what you actually use, even if it's not healthy, environmentally irresponsible or politically incorrect.

    I use only garnet as I got a couple hundred pounds of it free. Sometimes I have small jobs where I can recover it, but many times I have to go outside and blast away and let the elements wash it away.

    Second hand garnet still works pretty well, and I have a lot of that, too. Garnet is not appropriate for heavy blasting, of course, but for what I do it works very well.

    One interesting thing - I'd found a fossil embedded in sand stone. I blasted it out of the sandstone and kept the harder fossil in tact. That was impressive. Using that as a foundation I then discovered if you place a large wet maple leaf on a concrete paver, you can blast a pretty nice image around the perimeter of the leaf. When it ages (around here that means it gathers moss) it preserves that image.

      Since none of this stuff readily biodegrades whatever you use may stick around for a LONG time.

      I generally use black beauty, but I also use a plastic ground cover so I don't have inches of the stuff left behind for months till it washes away.

      My local tractor supply has 40/80 grit 50lbs on sale for $8

        I like glass beads myself. Very nice finish.

          I use crushed glass. Silicosis IS an issue to worry about and crushed glass isn't crystalline so it isn't a threat. I don't worry about cleaning it up, it's good for my driveway since it isn't paved.

            Since nothing is supposed to go in your lungs but air.(respirator,air supplied hood)

            I use plain ole silica or quartz sand,I like the quartz better since it cuts paint faster.$3.00 for 80lbs of play sand ain't bad.

            Cleanup is a cheap blue tarp on the ground and as long as it doesn't get wet,you can screen it and reuse it.
            I just need one more tool,just one!

              Evan,
              could you please provide a link for the crushed glass ?

              The few place I've seen it (or I thought it is what you describe)
              it was very expensive, too expensive to use only one time.

              It sound's like the stuff you describe is different, and I would like to
              try some.

                I buy it locally. It's a few dollars per bag. A link won't do any good as it is made locally in the next town. It's too expensive to ship something like this very far. Check with a local recycle center.

                  Crushed glass is trucked around Western Canada by the super bee (8 or 10 axle truck) presumably from assorted recycling centers and glass shops. Princess Auto has bagged crushed glass that is competitive with their other blasting media. Any Auto supply that supports body work should be able to supply glass for blasting.

                    I use play sand with my pressure washer. The Homedepot sells #500 for $33 or so. I mostly blast aluminum and concrete.

                      That will definitely require a good respirator.

                        Not really, the water keeps the dust in check. After i am done i just wash all the sand away.

                          Hi Ranger,

                          What kind of setup do you have for injecting the sand into the pressure washer?

                            I use a couple of cheap plastic traps, that I put down and then behind to the sides. Then you can clean it up for re use or adding it as fill to unpaved driveway.
                            I use black beauty for most stuff,as been stated from tractor supply or the local brickie and block mason joint. When they have it in stock.

                            And whether you like it or not

                            and it should be mentioned every time a blasting question is asked.

                            1.NOT know about Silicosis!
                            2.Think it is of no consequence if you only do it on occasion.
                            3.Or what I was told by some idiot buying a pressure pot at HF after his wife, asked a couple of us in the general area what safety things he would need? Because when it comes to his safety he his stupid as road kill.
                            "they just want to sell all that safety crap, I don't need it, I will do it in short shots and hold my breath" is what he said to us

                            I told his wife when he is planning on doing it make sure his life insurance is paid up and take the kids to the mall for the afternoon. While he commits a slow and painful suicide!
