BlastOne has declared an all-out War on Dust!



Dust is perhaps the #1 issue for surface preparation these days, and therefore BlastOne has declared an all-out War on Dust.

Why is dust such a problem?

  • Dust doesn’t just leave the blaster filthy – it also negatively affects his health
  • It damages the environment.
  • It reduces visibility, which, in turn, reduces blasting quality.
  • It disturbs neighboring areas.
  • It contaminates other projects and hinders other trades from working around you.

It’s 2019, and so far we’ve found nothing good about dust.

So, to tackle this problem, here are the top 4 simplest methods to reduce or eliminate dust on your jobsites, in order of simplicity.

#4. Ultra High Pressure Water Jetting – Water alone can be an incredibly powerful surface preparation tool. By using pumps that can develop 40,000 psi—which is 2,500 bar—you can strip coating, corrosion, rust and contaminants completely off the surface with no abrasive—just water.

You will often need to go and whip up the surface with abrasive blasting to meet the final specification but a whip blast is a much quicker and a lower dust alternative to blasting off a thick coating.

#3. Mist Blasting – By wetting the abrasive before blasting, much of the dust is reduced.

While blasting, some of the dust is generated from the abrasive particles themselves and dust is also generated from the pulverization of the rust and paint that is being blasted off the steel.

By wetting the abrasive, you are reducing the dust generated by the abrasive and also reducing some of the dust that is generated from the paint and rust coming off the steel.

#2. Use a Low Dust Abrasive – Many abrasives are naturally very dusty and extremely friable and will create a lot of dust even when blasting clean steel.

Using a highly efficient, low dust abrasive, GMA Garnet, will often reduce dust levels by 90%.

Using a high efficiency abrasive will produce less dust. You will finish the job faster and use less abrasive as well.

#1. Increased Nozzle Pressure – It's a shockingly simple solution, but having more nozzle pressure means that each abrasive particle does more work.

This means you end up using a smaller amount of abrasive. And the less abrasive you use, the less abrasive there is to break up on impact. This translates to lower dust levels when blasting with higher pressures.

Many people think that using a high pressure would increase the dust levels while blasting, but it turns out that the reverse is true because there is less abrasive to impact. View the Nozzle Presure Chart to see how increasing your PSI can improve your efficiency.

If you need to reduce dust on your blasting job, BlastOne can assist in selecting the correct equipment and process for your project.
