Choosing Between Wet And Dry Blasting: What You Need to Know?

Abrasive blasting is one of the reliable and time-tested methods of preparing a surface for applying fresh coating or other purposes. It saves you the time and effort to remove rust, coatings, and old paints from various surfaces. In addition, abrasives help clean and prepare wood, concrete, metals, and other surfaces.

Wet and dry blasting are two crucial abrasive cleaning methods for surface preparation and removing old coatings across commercial, residential, and other industries. Both are effective when it comes to preparing and cleaning surfaces.

However, it can sometimes become difficult for you to choose between the two - especially if you are going for such a thing for the first time.

For some people, wet blasting may be a better option as it reduces dust production, allows to strip and clean a surface, and more. On the other hand, some might go with dry blasting because it is a versatile, cost-effective, and overall efficient option.

At Atlanta Blasting Professionals, we understand the confusion you could have when deciding between Dry vs. Wet Blasting. Therefore, we've compelled this post to help you make a better decision in the end:

Wet Blasting vs. Dry Blasting

Introducing Wet and Dry Blasting

Wet blasting, as the name suggests, is used for cleaning or preparing surfaces using a mixture of abrasive media and water. The process is recognized for providing a smoother, cleaner finish. It is possible to remove old coatings from a surface without much dust production using this method.

The best part about wet blasting is that it creates cold sparks which removes static and reduces explosion-related risks.

On the other hand, dry blasting is slightly different because it does not include water to clean a surface. The process is similar to wet blasting, but it uses compressed air instead of water to propel abrasives.

The method suits those looking to get a top-notch finish for various applications. In the context of cost efficiency, it is a preferred option over wet blasting.

How Does Wet and Dry Blasting Work?

When differentiating wet and drying blasting, one should always compare how both abrasive techniques operate or work. By knowing the difference between their working processes, it could be easy for you to determine which best suits your needs. Let's try to understand how wet and dry blasting work:

How does Wet Blasting Work?

As mentioned earlier, wet blasting introduces water to the abrasive blasting process. Hence, it is evident that the process depends significantly on water and abrasive media. In wet blasting, various abrasive media such as recycled glass, garnet, baking soda, or crushed walnut shells are commonly used in combination with water. The mixture of water and these abrasives is propelled onto the surface at high pressure, aiding in the removal of coatings, paint, or rust without generating excessive dust.

Furthermore, you can use different types of abrasive media when using wet blasting methods. It is a crucial process for places where you want to keep airborne particles to a minimum. Including water also ensures that the process will help control heat generated during the blasting process - which lowers the risk of damage to the substrate.

How does Dry Blasting Work?

Dry blasting operates by using compressed air to propel abrasive media onto a surface. Unlike wet blasting, this method doesn't involve water. Various abrasive media options are available, including standard materials like garnet, aluminum oxide, and glass beads, among others.

Dry blasting's advantage lies in its higher abrasive velocity, facilitating the swift removal of old coatings. This method is particularly well-suited for outdoor environments and large industrial settings due to its efficiency. It finds widespread use in industries such as manufacturing, automotive, and construction.

Wet vs. Dry Blasting: Comparing the Advantages and Disadvantages!

The Advantages and Disadvantages of Wet Blasting

Wet blasting is an equally effective option for removing carbon, scale, rust, paint, and similar deposits. It effectively cleans molds and dies and prepares a surface for re-coating, re-painting, or bonding. Let's determine how beneficial this process can be by uncovering its main pros and cons:

Advantages of Wet Blasting

  • It can reduce dust generation to a larger extent while minimizing the environmental impact.

  • It allows maximum precision for surface preparation.

  • It is more effective in removing contaminants with better control.

  • It reduces heat generation during the process.

Disadvantages of Wet Blasting

  • It can cost relatively more than dry blasting.

  • It may increase the risk of corrosion -especially at a metal surface.

  • It could be more challenging to remove wet waste than dry waste.

The Advantages and Disadvantages of Dry Blasting

Dry blasting is helpful in many applications, such as removing carbon, scale, rust, and paint. Some other vital applications of dry blasting are engraving, decorating, and etching glasses. Here are some other considerable pros and cons of dry blasting you need to be aware of:

Advantages of Dry Blasting

  • It is ideal for various applications, from maintaining tools and equipment to surface cleaning and preparation.

  • It is a cost-effective process, considering the lower acquisition cost of using dry blasting tools.

  • It allows you to propel abrasive media at a higher velocity, providing better results with higher accuracy and speed.

  • It allows you to use different blast materials while eliminating the risk of corrosion and rust.

Disadvantages of Dry Blasting

  • Poses potential health hazards to individuals involved (can be mitigated with proper protective equipment).

  • Creates hot sparks, potentially leading to fire or explosions.
