Want to find out what Wet blasting is? Put simply, it’s the use of an abrasive blasting media and water to achieve a desired finish on a chosen surface. It’s often compared to Dry blasting, which is a similar finishing method only without the added use of liquid. 

In this article we’re going to answer the question ‘What is Wet blasting?’ and explain how it works, the differences between Wet and Dry blasting and the overall benefits of using Wet blasting for your finishing requirements.

What is Wet blasting and how does it work?

What is wet blasting

Wet blasting, also referred to as Vapour blasting, is an abrasive cleaning method that involves pressurised wet slurry which is applied to component surfaces for various cleaning or finishing effects. You most likely don’t just want to know what it is? But also how it works and what it can do, well the answer is quite a lot. The blast media that is used when wet blasting is moistened prior to impacting the surface,  the slurry mixture is then sent to a nozzle/s where regulated compressed air is used to adjust the pressure of the slurry as it blasts the surface. 

This method allows you to extensively clean, degrease, deburr and descale parts. This blasting method also removes paint, chemicals and oxidation and is perfect for high-precision composite etching for bonding. 

Wet blasting vs Dry blasting: The Difference between the two finishing methods

What is wet blasting

Wet blasting is often compared to a similar finishing process called Dry blasting. The main difference between the two is in the name, one uses water or liquid, Wet blasting, and the other doesn’t, Dry blasting. 

The mixing of liquid and abrasive media, which takes place in with the wet blasting process, means that the abrasive media particles hit the blasting material which may cause them to shatter. Whilst this happens in both Wet and Dry blasting, the difference is that due to the static charge in Dry blasting it can cause sparks. This possibility is eliminated when adding liquid, as it diffuses the dust produced during the process making it a safer process overall. 

When asking the question, it’s helpful to remember the finish it can provide too. Where Dry blasting is much more aggressive and can cause unwanted damage, the use of water with Wet blasting almost acts as a cushion which helps push the particles across the surface, resulting in a finer satin or polished texture. Due to this, it’s also very effective at removing coatings without damaging underlying material, unlike the harsher Dry blasting process. 

What are the benefits of Wet blasting?

As mentioned above, the Wet blasting process is less abrasive on materials and ensures a polished finish, without any static charges or sparks. There’s also the noticeable dust reduction when opting to use this, as the water stops abrasive dust particles floating around and impacting the finish – this is particularly great for open environments and improving your equipment life as the process is not as harsh on equipment. 

Another benefit is its sustainability and that it’s an all in one step process. You’re able to strip the surface and clean it at the same time meaning you won’t need to spend any extra time, money or resources on a separate rinsing process to remove media fragments. 

Wet blasting is perfect for those looking for affordable, quick and easy precise finishing results and it’s safe for your sensitive materials.
