Industrial sandblasting machines make up a $418.7 million global industry. More than a quarter of that market is in the US, with the country’s share being at an estimated $113.4 million.

What is sandblasting, and why is it such a massive market? Why should you even take the time to learn more about it?

This sandblasting guide lists the top answers to those questions, so be sure to read on.

1. Allows for More Efficient Surface Preparation

Sandblasting is the process of propelling ultra-fine particles of abrasives onto a surface. That’s why it’s also known as abrasive blasting. Silicon dioxide (AKA quartz), glass beads, and steel grit are common abrasive media.

During the sandblasting process, the machine shoots out the abrasives at high velocity. That high speed and force then allow the abrasives to clean the surfaces they hit. In this way, the abrasive materials can knock off dirt, rust, paint, and other contaminants.

All that makes abrasive blasting a crucial step in many surface preparation applications.

2. Contributes to Longer-Lasting Surface Treatments

Were you aware that home exterior paints can last anywhere from seven to ten years? On the other hand, interior paint has a typical lifespan of 10 to 15 years. As for sealants, such as those used in pipes, they can stay in good condition for up to eight years.

Those estimated lifespans depend on the pre-paint or pre-sealing preparation, though. With proper surface prep, adhesives and paints cling to surfaces better. The better their adherence, the longer they can last.

For that reason, professionals, from construction to painting and manufacturing, rely on sandblasting.

3. Provides a Quick Way to Restore Metals

According to Burbank Steel Treating Inc, sandblasting is effective for metal restoration. The abrasive materials can blast away corroded sections without harming the metal itself. Moreover, they can help remove grease, oil, residue, and grime build-up on metal surfaces.

If you need to restore steel, copper, zinc, or even aluminum parts, sandblasting can be a good option. This is also why many auto body repair shops use abrasive blasting to restore cars. Even the metal parts in heavy machines and equipment can benefit from this process.

4. Long-Lasting Surfaces Equate to Savings

Sandblasting benefits your wallet, too, as it plays a role in paint or coat longevity.

For example, a roof coat can adhere better to a properly prepped and sandblasted metal roof. As a result, the coat can last longer and be less prone to deterioration. This then translates to fewer unnecessary repairs and lower repair costs.

By contrast, experts say that inadequate surface prep is a primary cause of corrosion. Unfortunately, a rusty roof can start to leak and damage even the building’s interiors.

As you can see, the key purpose of sandblasting is to prepare, clean, and restore surfaces. Without it, it would be difficult to treat and get rid of imperfections on surfaces. Even structural materials, such as those in your home and car, can fail early if not for this surface prep method.

That’s how crucial sandblasting is, and it’s also why you should care to know more about it.
