A sandblaster is an industrial tool that uses a jet of abrasive particles to clean surfaces.
It’s best known for its use in removing rust, refinishing metals, and preparing concrete surfaces for painting or adhesives. But it can also be used as a surface grinding machine to remove welds from castings or for cleaning up machinery between batches of production runs.
What Exactly Is Sandblasting?
Sandblasting utilizes high-pressure air to propel particles (sand, glass beads, or walnut shells) at a target surface. It’s often used to remove paint, rust, and corrosion from metal surfaces – like the frame of an old car – but it can also be used for other things like grinding down welds on a cast iron piece. When performing this type of blasting, experts will typically use bonded abrasive in the form of hard-wearing media capable of removing material without damaging surrounding surfaces.
Using media that is too soft or friable will not produce optimal results since they tend to scratch more than blast away your intended target area. Sand comes in many different sizes and grades; some are glass beads, and others are coarse walnut shells. For example, fine sand is used when you want to achieve a smooth finish on the surface of the material after blasting.
The Equipment Needed for Sand Blasting
There are several pieces of equipment needed for sandblasting. These include:
The right nozzle
This acts as a portal through which the sand travels through on its way toward your surface. A good nozzle will be made of metal and have the same diameter as your sand. The best ones are also adjustable, allowing you to direct the sand to different areas at different speeds.
An air compressor
This is used to drive the pressure out through an air hose that connects directly to your nozzle. It’s what gives your sand a lot of power, making it possible to blast away tough grime without any problem! Remember, the general principle behind the action of the sandblaster is simple: air compressed by the compressor flows through a nozzle with holes drilled into it at high speed and under pressure, spraying small droplets of grit onto the desired material. The resulting spray removes paint, rust, grease, and grime very quickly.
You’ll need this to control how much pressure ends up inside your system. Without one, there would be no way for you to adjust the amount of force that goes into your job. Without proper regulation, you could end up with a mess after just a few minutes of use!
A blasting cabinet or booth
This will keep all the dust from the area contained in one spot instead of putting it into the workspace around you.
Why Choose to Sandblast?
There are several reasons you’d choose sandblasting over other removal methods. The most obvious one is that professional sandblasting services are easily and readily available. Another reason is that unlike some other options out there (i.e., scraping, grinding), once you shoot off the material with a sandblast gun or machine, you have a nice even surface. This means less prep work is necessary before painting or applying powder or liquid coatings.
The fact that this method does not involve harmful chemicals also adds to its appeal. However, some people argue against any blasting whatsoever since they worry about potential problems down the road with respect to dust in the air. Others prefer sandblasting because it is both fast and inexpensive.
As mentioned earlier, compressed air is used with sandblasting and can cause serious injury if not handled properly. To prevent accidents like cuts, abrasions, or even broken bones due to flying shards of material hitting you, do not attempt sandblasting on your own. Instead, call a professional sandblasting service provider who is not only highly experienced but one with all the necessary safety equipment.
