  1. Introduction A surface finishing process that involves impel machines is known as the sandblasting process. Also known as abrasive blasting.  Normally sandblasting and air compressors are used to spray abrasive particles on the surface with high pressure.   It is called sandblasting because it blows up the surface with sand particles. When the sand particles hit the body, the soft texture takes place.  Sandblasting makes the most of sand’s abrasive properties have a soft and glossy surface; however, some flaws also exist as physical faults. It’s a fact that sand is rough and chopped; due to these properties, it’s easy to wash away excess of it from the surface.   Sandblasting works in the same way as sandpaper. When it is rubbed on the surface it eliminates the excess material and creates a softer texture. 

  2. How Sandblasting Process Takes Place The sandblasting process starts with pouring the sand in the machine. It has a chamber through sand that is easily poured and filtered. The sandblasting device is also attached to an air compressor that further impels the sand particles through the nozzle.  You have to set the pressure; it depends on the settings. The standard pressure for the sand may vary with 50 to 130 PSI ( pound per square inch).  The sand is later burst on the soft surface. Its abrasive properties help in creating a frictionless surface. For example, cement is the outcome of sandblasting. When it is spilled and leaves it to dry, then sandblasting is applicable.  On the other hand, mobile media blast is in demand for many different purposes. Rust and paint removal is the most common use of it. Indeed it is very efficient for removing rust or paint from any type of surface instantly.  It is simply done by impelling sand by applying high compressed air. When the gritty material hits the surface, the rust is eradicated easily.

  3. Step 1: Decide Space For Operations  Clear out your workspace; make sure that there will be no harmful material around you. Usually, flying abrasive material hit toxic materials and cause incidents. So keep your precious belongings safe by covering them—safe them from being sandblasted. The space you chose for the sandblasting process should be open and airy. 

  4. Step 2: Make Yourself Safe Sandblasting is a very tricky and sensitive process. For that, you have to take safety precautions before starting it. It includes a helmet, face masks, and Gloves. If you don’t have it, find an alternate; the only thing you have to safely is your skin. You must cover it completely. 

  5. Step 3: Set the Sandblaster  To start any machine, it is the primary step to go through its manual thoroughly. As the sandblaster has the valves on its blasting unit and that needs to get close tight. Abrasives materials need to be fill in the tank,  with the help of a plastic funnel. Keep in mind that there are many types of abrasives easily available such as glass, silica sand, nutshell, etc. 

  6. Step 4: Set the Pressure Attentively First, to set the pressure, open the primary air valve and allow the tank to reach a minimum pressure of 40 PSI. It also depends on the different types of equipment. After a good pressure, the tank unlocks the sand air valve. 

  7. Step 5: The Blasting  In this step of the sandblasting process, shut down all the valves and move the nozzle against the target. Set it on a slight angle then apply composed motion. Stretch the target part with abrasives.

  8. Step 6:  Absolute Settings  Now you will gently increase the pressure to attain the likable results. You can take the pressure to a maximum of 100 PSI and keep examine the outcomes. After fixing the result, keep checking on the obtained results if optimal or not. Close all the valve and nozzle once you reach to the point. 

  9. Conclusion  Sandblasting is one of the most acceptable types of surface finishing. It is best for rough and challenging spaces. Simply it is the process of polishing and grading uneven surfaces by striking solid particles. With compressed air at high speed the process takes place placidly.
