WHAT IS A TYPICAL SANDBLASTING PROCESS?

Sandblasting is the process of using compressed air to propel abrasive media at a surface to clean, (usually paint & rust),debur, or to prepare a surface for a coating of some sort.

There are two kinds of sandblasters: “Suction” / “Siphon”” & “Pressure” Blast Systems. Pressure systems are ten times faster & much more effective, but also quite a bit more expensive.

There are two basic kinds of sand blasters: Blast Cabinets & Portable Blasters

There is a huge variety of abrasive blast media out there each has its purpose. One you want to stay away from is Silica Sand. Blasting with Silica sand causes Silicosis of the lungs…Do Not Ever Use It!!!

If you are looking to blast hand tools, such as saw blades, wrenches, etc., I’d recommend blasting them in a sandblast cabinet. (A “Suction/Siphon” cabinet would probably be sufficient…)

Sandblast Cabinets have adequate lighting, a dust collector, and two gloves you place you hands inside to blast within the cabinet. One nice part about blasting inside a cabinet is that all the dust is contained, so no respirator is needed. They are also relatively quiet, and some have abrasive separators which allow you to get the maximum life out of the abrasive blast media & consequently save money.

Below you will find the steps of a typical sandblasting process inside a cabinet:

  • Open Door
  • Place Item inside
  • Close Door
  • Turn On The Power
  • Place Your Hands Inside The Gloves
  • Grab The Blast Hose, or Suction Gun
  • Step On The Foot Pedal
  • Blast Surface
  • Blow-Off Item with Blow-Off Nozzle (Inside Cabinet)
  • Inspect
  • Repeat Blast If Needed
  • Open Door
  • Remove Item

    thanking you

  5. I will love to come for a sand blasting training or seminar because I want know more of sand blasting. Thanks

  6. what is typically the ratio of compressed air to the amount of blast media in the hose? I’ve seen 10% media and 90% air. Are these good numbers or should I expect a much different ratio? I’m looking at a big job and wondering what effect the weight of the media will have on the total weight of the hose.

  7. My partner and I stumbled over here from a different web
    address and thought I may as well check things out. I like what I see
    so i am just following you. Look forward to checking out your web
    page again.
