Micro Abrasive Blasting vs. Abrasive Blasting

Abrasive and micro abrasive blasting uses air to force small particles over a surface. It can be used indoors and outdoors. This process can roughen, smooth, polish, clean and shape a surface or object. It can be used on a variety of materials including: glass, stone, metal and plastic. It is also referred to as sand blasting and pressure washing. The type of abrasive used in the blasting process depends on the size and type of the surface being blasted and the desired results. The equipment used in abrasive blasting ranges from large industrial systems to small portable machines. The operator fills the blasting cabinet with the abrasive particles. The operator connects the cabinet to the hose with a nozzle. The size of the nozzle will vary depending on the application. The operator directs the nozzle at the object and uses the high-pressure particles to perform the work necessary.

Abrasive Particles

There are a variety of abrasives available for this process. Some of these particles are better for the environment than others. The most popular abrasive is silica sand but it is also the least eco-friendly. The dust created by the silica sand can cause breathing difficulties if it is inhaled. There are also mineral, metallic and synthetic abrasives that can be used. These particles create less dust and are less harmful. There are some organic particles available. These products include ground nut shells and kernels. These products are good for the environment and softer than most other abrasives, which enables them to work without causing a great deal of damage to a surface.

Abrasive Blasting Applications

Abrasive blasting can be used in a variety of other applications. This blasting process is used to engrave stone monuments and to create three dimensional signs. It is used to refurbish the surface of old buildings and create works of art. Abrasive blasting is also an effective technique for cleaning all types of commercial and industrial brick, stone and concrete.

Micro Abrasive Blasting

This process uses dry particles that are forced through a small nozzle. The small nozzle is able to create a fine stream of abrasive. The fine stream enables the operator to work on more detailed surfaces and in smaller areas. Micro abrasive blasting uses a stream fine enough to create a pencil-thin line. It can be used on delicate surfaces such as glass and eggshell. The nozzle on micro abrasive systems can be hand held or mounted on a bench to enable a more automatic operation of the device.


Both abrasive and micro abrasive blasting require special safety measures to prevent any accidental injury during the process. The operator of the nozzle should wear protective eye wear, work gloves, a respirator, ear plugs, a hooded suit and a helmet for protection. Any sandblasting job should be done in a well-ventilated area. If the work is done indoors, be sure the windows are open. If possible, use an oscillating fan set a low speed level, to circulate the air.
