Sandblasting can be extremely effective when performed correctly, but it also comes with risks. We understand why people want to DIY their projects, but we want to emphasize the importance of making an informed decision before attempting sandblasting on your own.
We will explore what sandblasting is, its applications, budgeting concerns, and, most importantly, safety concerns.
What Is Sandblasting?
Sandblasting is a surface preparation technique for various coatings, removing rust, paint, or contaminants. It involves forcibly propelling abrasive materials against a surface using compressed air or a centrifugal wheel.

The abrasive materials include sand, glass beads, garnet, aluminum oxide, and other media. This process effectively removes unwanted contaminants, old coatings, or rust from a variety of surfaces, leaving them clean and ready for recoating.
Applications of Sandblasting
Industrial surface preparation
Sandblasting is used in industrial applications to prepare surfaces for protective coatings.
Industries like oil and gas, manufacturing, and construction often sandblast to remove rust, scale, and other contaminants from metal structures. This process is crucial in preventing corrosion and maintaining the structural integrity of equipment.
Restoration enthusiasts often turn to sandblasting to remove old paint, rust, and other imperfections from vintage cars and machinery. It helps achieve a clean, smooth surface for repainting or refurbishment.
Sandblasting can strip paint, remove graffiti, or revitalize weathered wooden surfaces.
Cost is a significant factor when deciding whether to sandblast on your own or hire professionals. When you take on the project by yourself, you’re responsible for renting or purchasing all of the equipment you need and for covering costs if anything happens to your rented equipment or if repairs are required.
Here are some budgeting concerns to contemplate:
Investing in the necessary sandblasting equipment, such as a compressor, blast pot, and abrasive media, can be expensive.
The quality and capacity of the equipment will significantly impact the cost. Professional sandblasting companies already have these resources, saving you the upfront investment.
The choice of abrasive media and the quantity required can add to your expenses. If you opt for DIY sandblasting, you’ll need to purchase, transport, and handle the abrasive media, which can be cumbersome and costly.
Safety is a paramount concern when sandblasting. You must invest in the proper safety gear, including a respirator, protective clothing, and eye and ear protection. Professional sandblasting companies prioritize safety and come equipped with the necessary equipment.

Training and Expertise
Mastering the art of sandblasting takes time and practice. Without proper training, you may waste abrasive media, damage the substrate, or, worse, put yourself at risk. Professional sandblasters are trained to perform the job efficiently and safely.
Many regions have regulations governing sandblasting due to the potential environmental hazards associated with the process.
You’ll need to comply with these regulations, which can incur additional costs and administrative efforts. Professional companies are well-versed in local laws and will handle compliance on your behalf.
When considering DIY sandblasting, safety should be your top priority.
Sandblasting can be hazardous for a variety of reasons, including:
Sandblasting generates dust and fumes that can be harmful when inhaled. The abrasive media used can contain toxic substances, and the process can release lead particles from old paint. Without the appropriate respirator, you risk serious health issues.
Hearing and Eye Protection
The high-pressure air used in sandblasting produces noise levels that can cause permanent hearing damage.
In addition, abrasive media particles can strike the eyes at high velocity, potentially causing severe injuries.
Skin and Body Protection
Exposure to abrasive media and rebounding particles can harm your skin and pose a risk of injury. Proper protective clothing, including gloves and full-body suits, prevents accidents.
DIY sandblasting can lead to the contamination of your surroundings, including neighboring properties and the local environment. Controlling and cleaning up the abrasive media and debris can be challenging.
