If you decide to strip a surface clean manually, know that you are in for a very time-consuming chore. Fortunately, there is an alternative. If you want to remove large amounts of paint and rust, without spending too much time and effort, you should opt for dustless blasting. This type of blasting, also known as wet blasting, has become somewhat popular in the last few years, and for some good reasons, which we will cover throughout this article.
But, before we do that and before you get dustless sandblasting, let’s take a look at the blasting method itself and cover some general points.
Before we get down to the reasons why you should utilize dustless sandblasting, let’s just clarify what this method means and encompasses. Even though it is called “dustless,” this process of blasting does not remove all the sandblast dust. Instead, it helps to suppress it greatly. Dustless blasting typically utilizes water to moisten the dust, which is usually a result of the blast fragmenting once it hits a particular surface.
This exact procedure can be performed in some ways, by injecting water directly into the blast media, right at the tip of the blast nozzle, to mixing the blast media and water inside to blast pot. Regardless of the method used, the overall goal is still to reduce the amount of dust during the sandblasting process substantially.
Key benefits of the dustless blasting method
No health risks
Dustless blasting has some advantages over the more traditional sandblasting methods. For starters, it is known to remove any health risks associated with sandblasting completely. Numerous medical studies have shown that standard sandblasting techniques can contribute to the development of silicosis, which is a crippling lung disease. Since dustless blasting typically utilizes a wet media, it can hit a surface much harder and strip it much more efficiently. Since there is almost no dust left, it is undoubtedly the cleanest method of blasting out there. As a result, there is almost no risk of the onset of silicosis, which, in turn, makes it perfectly safe for the workers and the operators to be in the close vicinity during the process.
Less need for abrasive materials
With dustless blasting, there is a reduced amount of abrasive materials needed for the task. It also takes much less time to finish a job, and it doesn’t warp fragile or thin materials due to friction. Furthermore, dustless blasting is considerably less expensive than other methods, requires fewer containment measures, and leaves any surface perfectly decontaminated and prepared for the next step.
Keep in mind that with dustless sandblasting, it only takes around 4 to 5 bags of glass abrasive to fully strip a car, and within just a couple of hours. However, if you decide to use 8 or 9 bags of the same abrasive materials, you could strip your car in no more than an hour.
Last, but not least, dustless blasting allows for an easy and simple cleanup job. For that matter, the operator can lay down plastic across the affected area in advance, to quickly collect the abrasive media later. Since there are no traces of dust, the abrasive media can be quickly localized and cleaned once the job is finished.
