What Is Sandblasting? Industrial Standard 1 for Surface Preparation

What is sandblasting, how is it done, and in which industries is it used? A detailed guide to sandblasting machines, surface preparation techniques, and industrial applications.

The question “What is sandblasting?” is an important topic frequently asked in the context of metal surface preparation and industrial production processes. The sandblasting process involves removing rust, paint, and dirt from a surface using high-pressure abrasives.

Sandblasting (abrasive blasting) is one of the most effective surface preparation methods used for cleaning, roughening, or preparing metal and other hard surfaces prior to coating.

In industrial production, the sandblasting process—which is performed prior to painting, coating, or welding— removes rust, oxide layers, oil, and old coatings from the surface. It also creates an ideal surface roughness profile that allows the coating to adhere properly.

Today, sandblasting has become a standard production step in many industries, ranging from steel construction to automotive manufacturing, and from energy facilities to the shipbuilding industry.

How Does Sandblasting Work?

In the sandblasting process, abrasive particles are propelled at high speed onto the surface using high-pressure air or turbine systems.

Thanks to this process:

• Rust and corrosion are removed

• Old layers of paint and coating are removed

• Coating adhesion is improved by roughening the surface

• A uniform profile is formed on the surface

This microscopic abrasion process forms the basis for the long-term durability of surface coatings.

Why Is Sandblasting Necessary?

Although coatings or paints may appear to be applicable directly to a surface, coatings applied without proper surface preparation will fail within a short time.

Common problems on surfaces that have not been sandblasted:

• Paint Blistering and Peeling

• Rapid corrosion formation

• Poor coating adhesion

• Rising maintenance and repair costs

The correct sandblasting procedure is:

• Extends the life of the coating

• Increases surface strength

• Optimizes paint consumption

• It reduces production costs in the long term

For this reason, sandblasting is not merely a cleaning process in industrial production , but a strategic surface engineering process.

Applications of Sandblasting

Sandblasting technology is used in many different industries.

Main applications:

• Steel structure manufacturing

• Automotive and related industries

• The Shipbuilding and Maritime Industry

• Oil and gas pipelines

• Energy generation facilities

• Foundry and heavy industry

• Agricultural machinery and construction equipment

In these industries, sandblasting plays a critical role in product safety and durability.

Types of Sandblasting Machines

Different sandblasting systems are used depending on industrial production needs.

Drum Sandblasting Machine

Used for the automatic cleaning of small and medium-sized mass-produced parts.
Commonly used in the automotive and foundry industries.

Pipe Sandblasting Machine

Ensures uniform cleaning of both the inner and outer surfaces of pipes.
Used in oil, gas, and infrastructure projects.

Sandblasting Cabins

These are closed systems designed for manual sandblasting applications.
They ensure operator safety and a controlled working environment.

Wet Sandblasting Systems

It minimizes dust formation and can be used on delicate surfaces.

Sandblasting Equipment

A professional sandblasting system consists of more than just a sandblasting machine.
The following equipment is required for an efficient system:

• An air compressor with sufficient capacity

• Sandblasting tank (blast pot)

• Abrasive material

• Sandblasting nozzles

• Filtration and dust collection systems

The proper selection of these components directly affects sandblasting performance.

Sandblasting Abrasives (Blasting Media)

Various abrasive materials can be used in the sandblasting process. Today, for health and environmental reasons, silica sand is no longer the preferred choice in many applications.

Commonly used abrasives:

• Steel shot

• Steel grit

• Glass bead

• Recycled glass abrasive

• Aluminum oxide

• Organic abrasives (walnut shells, etc.)

The selection of an abrasive is based on the following factors:

• Part material

• Type of coating to be cleaned

• Desired surface roughness

• Production capacity

---

Sandblasting Safety

Since the sandblasting process is carried out using high pressure and abrasive particles , workplace safety measures are of critical importance.

For operator safety:

• Respiratory masks and air-supplied helmets

• Protective clothing

• Eye and Face Protection

• Enclosed booth or sandblasting room systems

It is required to use it.

In addition, dust control and filtration systems must be in place in areas where sandblasting is performed.
