The Main Difference Between Dry and Wet Blasting.

Cleaning big surfaces of old paints, grease or rust takes a long time and it is also very costly if you do it manually. Therefore, in the industry where this process is repeated over and over again, workers use blasting media to clear away the unwanted particles sticking on the top of a metal or any other solid surface. The blast media could be the stainless-steel round cut wire shot, glass beads, copper shots, aluminum cut wire shot et cetera. When we talk about the blasting method to clear away the surfaces, then two different processes come to our mind, dry blasting and wet blasting. While the overall process in both these remains the same, there are certain variations which makes them suitable for different kind of jobs. In this article, we will share with you the main differences between dry and wet blasting so that you can choose one which will fulfill your requirement.

Dry blasting

In this process, the abrasive media like the cut wire shot is forcefully ejected through a nozzle and when it hits the surface of a metal or any other hard sheet, then it removes any old paint, grease, or rust quickly. There are multiple advantages of using dry blasting to clean surfaces include the following.

Efficiency.

This is a highly efficient method of cleaning old coatings from the surfaces of metal surfaces very fast.

Cost-effective

This method is very cost-effective because you can recycle the media multiple times and the overall investment in the equipment that you need for dry blasting is also within a reasonable range.

Versatility

This process requires very little equipment and is very efficient when you want to clear large areas. Due to these advantages, you will find dry blasting commonly being used across workplaces in various industries as well as in real estate sites.

When blasting

This process is similar to dry blasting but in this process in addition to the dry abrasive like a cut wire shot, you also add water. The main advantages of this process include the following.

Little pollution

As water is used in addition to the abrasive media, it reduces the chance of dust and other airborne particles contaminating the air.

Hydrostatic forces

As water is used in this process, it reduces the abrasive media significantly. Therefore, you will need less abrasive than you would otherwise need if you had opted for the dry blasting method.

Cleaning

In this process, you cannot only strip the surface of any foreign contaminant but also clean it afterward as you are using water.

There are no static charges

Abrasive blasting can cause static charges which can lead to fire on blast if it is done near any combustible gas or other fuel. However, when charging is not creating any static charges, thereby reduces the danger of blast.
