How Abrasive Blasting Works + Common Questions

industrial sandblasting services

What is Abrasive Blasting?

Abrasive blasting, sometimes called media blasting or grit blasting, is the process of using pressurized air or water to powerfully blast abrasive media against a surface to remove old paint, corrosion, decay, dirt, graffiti, and both biological and atmospheric contamination. Abrasive blasting is valued as a fast and highly effective method of cleaning and restoring surfaces and preparing them for optimum paint adhesion.


What Types of Contaminants does Abrasive Blasting Remove?

Abrasive blasting can remove nearly any type of unwanted material including old paint, corrosion, graffiti, rust, dirt, grease, mold, biological growth, and residue from atmospheric contaminants.


What Blasting Media Are Used in Abrasive Blasting?

Some commonly used blasting media include sand, baking soda, glass beads, coconut shells, walnut shells, and garnets.


Will Abrasive Blasting Cause Damage to the Original Material?

Not if done properly. A trained and experienced contractor will know which blasting technique and blasting media are best suited for each project. For example, blasting steel and blasting more delicate masonry or thin metal require different blasting methods. This is extremely important to achieving the desired results while protecting the surrounding environment and preventing damage to the original surface material.


Does Abrasive Blasting Require Special Equipment or Training?

Yes, it is extremely important that abrasive blasting is performed by knowledgeable and experienced technicians using best-in-class equipment to achieve successful results and ensure the safety of the technician, surface, workspace, and surrounding area.

Types of Abrasive Blasting Methods

Dry Abrasive Blasting

This is where pressurized air is the force used to blast abrasives against a surface to remove old paint, corrosion, decay, dirt, graffiti, and/or biological and atmospheric contamination.

Sandblasting and soda blasting are well-known forms of dry abrasive blasting. Sponge-Jet® blasting is an innovative low-dust dry blasting technology where sponge blasting media is propelled onto a surface where it abrades the surface while also capturing the vast majority of dust, debris, and hazardous particles. 

Wet Abrasive Blasting (also called vapor abrasive blasting)

This is where pressurized water is the force used to blast abrasives against a surface. By incorporating water, dust is suppressed by at least 92%, which achieves excellent blasting results with minimal mess and clean up, better workspace protection, and far less environmental impact.

Commonly called wet abrasive blasting or vapor blasting, this process is sometimes referred to as wet sandblasting, hydroblasting, slurry blasting, low-dust blasting, or dustless blasting.

*There is no such thing as 100% dust-free blasting!

Be cautious of those dust-free claims! While today’s advanced blasting techniques offer great advantages by vastly suppressing dust (by as much as 92%!), 100% dust-free blasting is a myth.

Even so, the dust suppression achieved by using vapor blasting, and Sponge-Jet® Blasting, is still extremely advantageous and can minimize prep and clean up, reduce health and safety hazards, and protect the environment and your space exponentially over traditional dry blasting methods such as sandblasting or soda blasting.

Low-Dust Abrasive Blasting Options

Some settings and environments are not compatible with dust-producing blasting methods like sandblasting. McCahill Painting offers innovative techiniques like vapor blasting and Sponge-Jet® blasting, which greatly suppress dust (by 92% or more!) and deliver excellent results with minimal mess and clean up, better personnel and workspace protection, and far less environmental impact.

Low dust abrasive blasting is often used in the following situations:

  • Indoor/crowded settings and worksites – minimizing dust minimizes mess as well as inhalation and visibility concerns
  • Outdoor urban or high-density areas – low dust blasting does not require the extensive containment measures necessary when dry blasting to keep dust within legal safety limits
  • Industrial and other settings where flammable gasses may be present – low dust blasting minimizes the explosive potential of dust as compared to traditional dry abrasive blasting

Safe Abrasive Blasting

Abrasive blasting is an extremely powerful process requiring diligent safety precautions and a high degree of skill. It is extremely important that blasting is performed by knowledgeable and experienced technicians using properly maintained equipment and protective gear to ensure the safety of the technician, surface, workspace, and surrounding area.

McCahill Painting has maintained an impeccable safety record for more than four decades, and we  continually invest in abrasive blasting training and best-in-class equipment. In addition to carefully protecting people and workspaces, we utilize eco-conscious methods whenever possible to reduce the environmental impact of our work.
