If you have never heard the term “mobile sand blasting”, then thankfully you have come to the right place. This brief guide will outline everything you need to know about the process, including the equipment you need, the advantages, variations of grit smoothing, the purpose of the process and other relevant information. If you have never used the proper equipment before, make sure you read this guide for critical safety information.
How does it work?
Mobile sand blasting works simply; however, it can only be successful if the equipment is operated safely and carefully. Each machine comes with a chamber where the two materials are mixed. Once the two elements are mixed into a single material, the solution travels through a hose connected to the machine and out through the nozzle. The device operates in a similar fashion to a gerni (a high-pressurised water hose – used to clean pavers and concrete).
The device churns out solid particles at high speed, the force of which is perfect for smoothing abrasive, rough surfaces or removing contaminants, dirt and grime. When the machine is operated successfully, the results are flawless.
Mobile sand blasting is straightforward; however, the machinery must be used appropriately and safely. Firstly, dry grit smoothing produces a lot of dust, which could contain harmful toxins. When operating the device, make sure you wear a face mask (those in close vicinity to the device should also be wearing facial masks).
You should also wear a helmet when operating a device. This is because you could seriously injure yourself if you were to fall over while operating the machine. Because the high-powered stream can spit out chunks of concrete, steel and other materials, it is also vital that you wear safety glasses and thick overalls. Both glasses and overalls are legally required on most construction sites, depending on what surface is being treated.
Types of mobile sand blasting
Wet grit smoothing works in a variety of circumstances. If you need to remove paint, a sealant or coating from a metal surface (like stainless steel), then wet mobile sand blasting is an option available to you. It can also be applied to wooden structures and brickwork, meaning it works for brick homes. Concrete driveways and pavers can also be cleaned quickly and effectively using mobile sand blasting techniques.
Wet abrasive smoothing is essential if you don’t want to produce dust by-products. Because water is combined with the mixture, it massively reduces the amount of dust created by the device. While the dust itself isn’t toxic, there could be small abrasive substances (like steel and rust), which you do not want to inhale.
Dry mobile sand blasting is the more common form of this process. Generally, dry grit smoothing is used for metal surfaces, like trailers, trucks and automobiles. It is advantageous in removing rust and corrosion, which forms on the metal surface after wind and water erosion. If you want to remove a coating or sealant on a piece of iron, then dry grit smoothing will work correctly (only if you administer it safely).
It is recommended that you hire a professional to handle your mobile sand blasting needs. In terms of cost, prices range depending on the size and scale of the project. Most professionals charge somewhere between $200 to $300 per hour (including GST).
How long does it take?
Again, the length of the project is predicated on the size of what needs to be treated. For example, removing paint will only take a few second, so stripping the paint off an external wall shouldn’t take too long at all.
