The type of sand or abrasive material used for sandblasting depends on the surface and material being cleaned, as well as the desired outcome. Some common types of abrasive materials used in sandblasting include:
- Silica sand: This is the most commonly used abrasive for sandblasting. It is relatively inexpensive and can be used to clean a variety of surfaces, including metal, wood, and stone. However, silica sand can be a respiratory hazard and should not be used in enclosed spaces without proper ventilation.
- Aluminum oxide: This abrasive is harder and more durable than silica sand, making it well-suited for cleaning metal surfaces. It is also suitable for cleaning glass and ceramics.
- Glass beads: These tiny beads are made of crushed glass and are often used for cleaning delicate surfaces, such as car body panels and aluminum surfaces, where a smooth surface finish is desired.
- Garnet: Garnet abrasive is known for its durability and low dust production. It is suitable for cleaning a variety of surfaces such as wood, metal, and stone.
- Plastic abrasives: These abrasives are made of tiny particles of plastic and are commonly used to clean softer materials like wood, rubber, and plastics.
It's important to note that before starting any sandblasting project, it's important to properly assess the surface and material to be cleaned and choose the appropriate abrasive material. Using the wrong abrasive can damage the surface or create an undesirable finish.
