Why is the Name Sandblasting?
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.
2. Ensure you have all the safety clothing that you need when you start sandblasting.
Every job needs protective gear. Safety cloths are also used when sandblasting. Before you blast your car, you should have the following safety gear.
Clothing to keep you safe. It has long pants and long-sleeved shirts.
Safety helmet /goggles.
3. Choose the media to use for sandblasting.
How you choose the media to use depends on what you want to sandblast. Each part of the car can be blasted with a different type of media.
Take the case of sandblasting the underside of a car. Rough grit will be used as the medium. In the same way, if you want to sandblast the body frame, you should use very small pieces of sand.
Why? Because the car’s body frame is made of thin materials that can bend when there is a lot of pressure on them.
4. Protect and cover areas that can get damaged during blasting.
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.
Do a random check of the work after you’re done to make sure it meets the standards.
