Have you ever seen a metal surface that looks brand new despite its age? It has probably been subjected to a cleaning process known as sandblasting.
This industrial technique uses a jet of compressed air loaded with abrasive particles to remove rust, paint, dirt and other contaminants from a wide variety of surfaces.

What is Sandblasting?
Sandblasting, also known as shot peening or sandblasting, is a cleaning technique that uses abrasive particles propelled at high speed by specialized equipment.
These particles impact the surface to remove rust, paint, embedded dirt or industrial waste, leaving the surface clean and ready for further treatment. Its precision and power make it an indispensable tool in sectors such as construction, restoration and industry.
Its history dates back to the late 19th century, when it began to be used in heavy industries for cleaning machinery. Since then, its use has evolved thanks to innovation in abrasive materials and safer and more efficient equipment.
Although this technique is best known as sandblasting, different types of abrasives are now used, such as ground glass, baking soda, and even environmentally friendly materials such as crushed walnut shells or dry ice, depending on the sensitivity of the surface to be treated.
What can be cleaned with sandblasting?
This cleaning method is highly versatile and is suited to a wide variety of materials and surfaces. Some common examples are:
- Metal: It is used to remove rust, paint and grease build-up on tools, mechanical parts and metal structures. For example, it is very effective for restoring wrought iron railings or the chassis of old vehicles.
- Stone: It is ideal for cleaning historical monuments, building facades and stone sculptures, restoring their original appearance without damaging them.
- Wood: In the field of restoration, it is used to remove layers of varnish or paint from antique furniture or wooden structures, respecting the natural texture of the material.
- Glass: Although less common, sandblasting is used for decorative engravings or specific cleanings on resistant glass.
In practice, sandblasting is very useful for removing old paint from exterior walls, removing construction debris from rough surfaces or cleaning large industrial machinery, restoring its functionality and prolonging the life of the equipment.
Advantages of Sandblasting
Over the years, shot blasting has become a popular technique due to the numerous benefits it offers compared to other cleaning and restoration methods. Some of its main advantages are:
- Deep and effective cleaning: This technique can remove the most difficult layers of dirt, paint or rust, even in hard-to-reach places. For this reason, it is common to use sandblasting on rusty industrial machinery, achieving a complete cleaning that manual methods could not achieve.
- Application versatility: Sandblasting is suitable for a variety of materials and surfaces, from tough metals to delicate stones. A clear example is its use in the restoration of historical monuments, where precision is required to remove dirt without damaging the structure.
- Preparation for subsequent coatings: By cleaning and polishing a surface, sandblasting leaves it perfectly ready for the application of paint, varnish or protective coatings. For example, on metal structures, it is used to ensure better paint adhesion, which helps prevent corrosion and prolongs the life of the material.
- Ecological and efficient method: Compared to chemical methods, shot blasting is less polluting and can be performed with environmentally friendly abrasives such as crushed walnut shells. It is also a fast technique, which reduces downtime on industrial or construction projects.
Disadvantages of Sandblasting
While sandblasting offers many benefits, it also has some limitations that need to be considered. These include:
- Generation of dust and waste: The process produces a large amount of dust and particles that can be harmful if appropriate protective measures are not used. In closed or poorly ventilated spaces, this dust can represent a risk to health and the environment. Therefore, it should always be applied by experts in the area.
- Requires specialized equipment and training: Correct use of sandblasting requires specific machinery and trained operators. This is essential, as the technique must be used correctly to ensure safety and the best results. sandblasting cleaning results.
- Not suitable for delicate surfaces: Not all surfaces can be cleaned by sandblasting. Some, such as thin glass or soft wood, can be damaged by the impact of abrasive particles. It is therefore important to evaluate the material before proceeding to avoid irreversible damage. We recommend that you read about the Surfaces where sandblasting should not be used.
- Specific regulations in some places: In certain areas, the use of abrasives such as silica sand is regulated due to the health risks associated with crystalline silica dust. In these cases, it is necessary to opt for alternative abrasives and comply with local regulations.
