Why Is Sandblasting Beneficial?

Sandblasting or media blasting may swiftly remove paint from an automobile without harming the metal or plastic below. It may also be used to remove calcium deposits, chromium, and rust from pitted surfaces. Sandblasting, on the other hand, is ineffective on anything sticky, such as grease or asphalt. Before sandblasting, such materials should be cleaned with a cleaner and pressure washed.

How to do a sandblasting

Sandblasting is a strong method for removing paint from practically any section of a car’s body. Paint, corrosion, and other coatings are all scraped away using a sandblaster, leaving a bare metal surface suitable for priming. It is one way to consider when refurbishing an automobile or achieving that exact factory match. However, for the procedure to be effective, it must be carried out correctly.

Choosing the right place

Sandblasting should be done outside, away from the house. In this manner, the media you’re utilizing won’t have an impact on others or even nearby places.

Ensure your safety

Protective gear is required for any profession. Sandblasting, too, has protective clothing. Before you start blasting your automobile, make sure you have the necessary safety equipment.

  • Clothing that protects you. Long sleeve shirts and long pants are included
  • Wear a dust mask
  • Goggles/helmet for safety
  • gloves for the hands

Selecting the right sandblasting media

Sandblasting automobiles necessitates careful thought when selecting a blast media; the type of blast media you choose will be determined by the portion of the car you wish to sandblast and how frequently you intend to sandblast cars. Because a car’s underbody is steel, it can typically be blasted with a variety of blast media. However, the body itself is often constructed of thinner material and can distort or be damaged if due attention is not given while sandblasting. Fine grit broken glass or baking soda is an effective blast media that may be used on any component of an automobile. Baking soda, on the other hand, requires less exact control of pressures and other parameters. Whether you use baking soda or broken glass, you must ensure that pressure is appropriately adjusted during blasting and that vulnerable sections of the automobile are protected.

Cover the sensitive parts

When sandblasting a car, the windows might be damaged owing to the high pressure of the sandblasting material. To avoid this, use glass protection. It can be difficult to properly protect the windows, but important tips include avoiding pointing the sandblast nozzle near the window and covering the window with protective layers. One option that may work is a thick rubber lining, similar to that used for roof coverings. This would need to be properly secured to ensure it stays in place and protects the glass from any blast media impacting it.

Adjust the sandblast pressure

After you’ve chosen your sandblast material, you’ll want to start setting up your sandblast pot. When sandblasting an automobile, the secret to success is to start with moderate pressure and gradually raise it. This is especially critical on the hood and panels, where excessive pressure might cause the panels to distort or break. Crushed glass often only requires pressures of 26–36 psi to efficiently remove excess paint. If you believe you require more pressure, make sure to test the settings on a scrap piece of metal that is comparable in size to the automobile panel to ensure that it does not distort the panel.

Sandblasting the surface

It’s time to start to work after you’ve double-checked that all of the preceding stages have been completed. Make sure you’re paying attention to the various surfaces you’re dealing with. However, you reduce the pressure on surfaces with thin materials. The suggested pressure for the tougher surfaces is high. Continue doing so until the entire car is blasted.
