Sandblasting is a general term for any rough, abrasive material used to clean. Stay with me, because now we’re going to talk about real stuff.

How to Sandblast a Car

As we’ve already said, the process involves taking off paint or rust from the car’s body or frame. It uses small, rough particles that are moved by high pressure. If you point the blaster’s nozzle at the surface, the paint or rust will come off.

There is a way to go about doing this.

1. Choose and set the area that you will use to carry out sandblasting.

Sandblasting should be done outside, away from your house. So, the medium you are using won’t have any effect on other people or even the areas around you.

Dust mask.

Safety helmet /goggles.

Hand gloves

Why? Because the car’s body frame is made of thin materials that can bend when there is a lot of pressure on them.

The pressure used to move the medium is so high that it can break weak parts on your car.

Some parts of the car, like the window pens, headlamps, and tail lamps, are easy to break. Also, if the blaster nozzle points at door handles or side mirrors, it can damage them.

It would be smart to put a thick, strong sheet over these spots. You can also take these parts off to keep them safe.

5. Ensure you adjust the sandblaster pressure

Pressure needs to be applied at different levels in different places. You won’t use the same amount of pressure on the windows to get the paint off as you will under the car.

These parts are made of a variety of materials and have different thicknesses.

Technicians say that you should start with low pressure and work your way up to higher pressures. It depends on what you’re painting on.

6. Blasting the surface

After you’ve made sure you’ve done all of the above, it’s time to get to work. Watch out for the different surfaces you are working on. But when the material on a surface is thin, you lower the pressure.

The recommended pressure should be high for the harder surfaces. Keep doing that until the whole car is blown up.

7. Inspection

Do a random check of the work after you’re done to make sure it meets the standards.
