What Can Sandblast Be Used For?


What can sandblast be used for? 


Sandblasting is the process of spraying granular abrasive to the surface under high pressure to remove rust, paint, corrosion, or other substances before treating or painting. When the abrasive is applied by high pressure, the surface is effectively washed and cleaned by friction. This process is widely used in many industries, and sandblasting is a critical part of surface finishing.

Although the name comes from the use of sand in the sandblasting process, many materials are used for it with development. According to the ideal roughness of the target surface, water even is used. Soft materials, such as crushed walnut shells, can be used on softer surfaces, while the hardest finishes may need grit, sand, or glass beads.

Common Applications



1. Contaminants Removal

During or after manufacturing, your components may be stained with contaminants, which will seriously affect the contact between the coating and the surface. One of the culprits is oil or grease. Even the slightest oil layer can’t be underestimated because it may cause your parts to produce unqualified results. In the process of renovation, we usually need to remove another common surface contaminant, which is old paint. The paint is challenging to remove, especially if it has many layers. Some grease, paint can also be removed by some chemical methods, but this may require a lot of people and need storage of chemicals. Therefore, sandblasting is a more efficient and safe alternative.

2. Rust Removal

If your work involves refurbishing weathered parts or surfaces, rust removal may be the main problem you will face. Because rust is the result of a chemical reaction between oxygen and metal, which means it is hard to remove it without damaging the surface. If we do this, it is likely to produce uneven surfaces or pitting. Sandblasting can effectively remove rust and restore the metal surface to the pre-oxidation state. In this way, a smooth and shiny surface will be obtained.

3. Surface Preparation

In addition to removing contaminants and rust from the surface, sandblasting can also create an ideal surface state to accept new finishes or coatings. Sandblasting removes the outer material from the surface, leaving a smooth surface to prime the application. It allows the treated surface to better accept any paint, coating, etc.

Specific Applications


Sandblasting can be used to clean cars, rusty old metal parts, concrete, rocks, and wood. Blasting glass, rock, and wood belong to artistic processing. Personalized items and signs by sandblasting make people delightful and have a sense of achievement.

Cleaning cars, concrete, rusty metal, and paint are also the main applications of sandblasting. In the cleaning process, you can work easily without too much investment. If the object you need to clean is a complex area with deep grooves, it is most appropriate to clean it with fine abrasive particles. Because the sandblasting media are very small, they can easily reach the interior of the object. Cleaning complex surfaces with sandpaper require a lot of effort, and it is even impossible to achieve the ideal surface.

The following is a list of sandblasting applications:

1) Car restoration

2) Concrete cleaning

3) Blasting for glass rocks, and boulders

4) Aircraft maintenance 

5) Jean clothing fabric treatment

6) Cleaning building rust and bridges
