Sandblasting vs. Glass Bead Blasting

Sandblasting vs. Glass Bead Blasting: Which Is Right For Your Project?

Sandblasting is a common method used to clean, repair, and decorate different types of surfaces. In sandblasting technology, both sandblasting and glass bead blasting are often used to improve the appearance and texture of objects. However, for projects that require the use of sandblasting technology, the choice of sandblasting material is a matter that needs to be carefully considered. So, which material is more suitable for sandblasting and glass bead blasting? This is a question worth discussing.

This article details the differences, advantages, and applications of sandblasting and glass bead blasting.

The difference between sandblasting and glass bead blasting

Sandblasting and glass bead blasting are two common surface treatment methods, and they have some differences in their processes and effects.

Sandblasting is a surface treatment method that uses high-pressure gas to spray abrasive particles onto the surface of an object to achieve the purpose of removing dirt, oxide layers, coatings, and more. The abrasives used in sandblasting can include different types, such as metal abrasive grains, quartz sand, and wear-resistant steel grit. Sandblasting can quickly and thoroughly clean the surface of objects and can change their surface roughness to a certain extent, making it more conducive to subsequent processes such as spraying, painting, and coating.

Glass bead blasting is a method of surface treatment used for cleaning, polishing, and improving gloss by spraying glass particles onto the surface of objects. Glass beads are a softer, less abrasive material compared to other options – meaning they will not typically damage or scratch the surfaces they are being used on. As a result, glass bead blasting is ideal for removing dirt and coatings on the surface of an object, while also leaving a uniform, smooth finish that enhances the object’s appearance. The process can even create fine wear marks on the surface to further improve its gloss.

Therefore, there are differences between sandblasting and glass bead blasting in terms of abrasive type and surface treatment effect. The choice of surface treatment depends on the desired finish and the properties of the material.

Advantages of sandblasting and glass bead blasting

Both sandblasting and glass bead blasting have many advantages and can be widely used in various surface treatment fields to improve the quality of the product and its service life.

Advantages of sandblasting

1. Removal of dirt: Sandblasting can completely remove the dirt, pollutants and oxides on the surface, and restore the surface to a smooth state.

2. Improve adhesion: Sandblasting can leave a layer of fine and rough texture on the surface of the treated object, which can improve the adhesion of wet or paint and other materials, and enhance the durability of the coating.

3. Uniform treatment: Sandblasting technology can evenly treat the entire surface to ensure a consistent treatment effect without dead ends.

4. Fast and efficient: Sandblasting is relatively fast, and can quickly complete the processing of large areas or complex surfaces, improving work efficiency.

5. Applicable to multiple materials: Sandblasting can be applied to the surface treatment of various materials, such as metal, plastic, wood, ceramics, etc., and has a wide range of applicability.

Advantages of glass bead blasting

1. Good finish: Glass bead blasting can remove surface dirt while maintaining a certain smoothness on the treated surface without obvious burrs and roughness.

2. No damage to materials: The hardness of glass bead blasting is relatively low, and it is not easy to damage the materials to be processed. It is suitable for surface treatment with high requirements on materials.

3. Good controllability: the particle size of glass bead sandblasting can be adjusted according to requirements, so as to achieve different treatment effects and meet different needs.

Application of sandblasting

Sandblasting can be used in many different areas, here are some typical sandblasting applications:

1. Automobile industry: Sandblasting can be used for surface preparation before exterior painting of automobiles. It removes old paint, rust and other surface imperfections, giving new coats better adhesion and appearance.

2. Metal processing: Sandblasting can be used to remove the oxide layer, rust, grease, or other dirt on the metal surface. It is widely used in metal processing industries such as casting, welding, and sheet metal processing to achieve better surface quality and product performance.

3. Glass technology: Sandblasting can be used for the decoration of glass products and surface treatment before silk screen printing. By controlling the intensity and speed of blasting, unique textures and patterns can be created on the glass surface.

4. Stone processing: sandblasting can be used for the beautification and texture processing of stone surfaces. It removes dirt, scuffs and imperfections from the stone surface while leaving a natural matte finish on the surface.

5. Wood processing: Sandblasting can be used for cleaning and texturing wood surfaces. By sandblasting, you can remove dirt, old paint, or grease on the wood surface, and improve the texture and oil absorption of the wood surface.

6. Pipeline cleaning: sandblasting can be used for cleaning and corrosion treatment of the inner wall of the pipeline. Through high-speed sandblasting, the rust, dirt and attachments on the inner wall of the pipeline can be removed to improve the patency and corrosion resistance of the pipeline.

In addition to the previously mentioned applications, sandblasting can also be utilized for surface treatment and improvement in various industries including construction, ships, furniture, and molds. Nonetheless, it should be noted that the dust and waste that result from sandblasting need to be appropriately disposed of to prevent environmental pollution.


Before choosing between sandblasting or glass bead blasting, you need to consider the needs of your project. This includes factors such as surface texture, finish requirements, and desired abrasive finish. If you require a finer finish or a higher surface finish, glass bead blasting may be more suitable. Alternatively, if you need to remove stains or require more abrasive power, sandblasting may be a more affordable option to consider.


Is glass bead blasting safe?

Sandblasting tends to generate dust that can be a health hazard to the operator.

The price of sandblasting and glass bead blasting?

Generally speaking, the price of glass bead sandblasting will be slightly higher than ordinary sandblasting, because glass beads have a better finish and processing effect.

Can you sandblast aluminum?

Sandblasting aluminum is fine. Sandblasting can make the aluminum surface smoother, and increase its corrosion resistance and surface hardness.

Can you sandblast cast iron?

Yes, cast iron can be grit blasted and is commonly used for surface cleaning and pre-treatment of cast iron parts.
