Sandblasting is a term that describes a finishing or cleaning process that involves spraying high-pressure water with an abrasive material or media onto a workpiece.

Abrasive blasting or sandblasting process removes contaminants, previous coatings, changing the shapes, and smoothing or roughening the surfaces.

There are different types of sandblasting and abrasive blasting applications which require different blasting material, commonly known as blasting “media.”

It is not recommended to use traditional dry sandblasting that uses dry sand. It is because sand contains significant amounts of silica, which can cause serious respiratory problems if inhaled.

Many people find it too costly and unhealthy to blast with dry sand since it takes twice as much material. Therefore wet sandblasting with a pressure washer is becoming more popular because it uses water with sand or other abrasive material that is safe to use.

Washwith has prepared the following guide about sandblasting media to help you choose the fittest and appropriate sand media for blasting.
