Media blasting involves glass beads, sand or another medium is shot at a very high speed through a machine. The particles go across the surface of a hard material until the surface of the material is smooth. Media blasting is used to finish an item or take away rust or paint. In some cases, you can use media blasting to prep a surface for a new coat of paint. The type of media blasting material used depends on what the surface is made of and how much blasting the material can handle.
Medium blasting should include a soft or gentle material if you’re not sure which medium is best. You should work your way up to harsher materials if you see that the least abrasive material isn’t working. One of the gentlest materials to use is walnut shells, and this material doesn’t have a negative impact on the environment. Ground corn cob is also an option, since this material is biodegradable and won’t scratch the material that is being treated. The softest material to use for media blasting is pumice, and this medium takes away paint from soft grades of wood.
Media blasting can also include glass beads. The beads will make the surface soft and bright and this is more visually appealing than using angular media. The glass beads can be used about 30 times, since they can be recycled. It’s best to use glass that is 100 percent recycled.
Media blasting for a car should involve plastic beads. This is because the beads are abrasive enough to get rid of corrosion, but won’t scratch the surface of the car. The beads also have a high stripping rate and will keep the car looking like new after the blasting process.
Media blasting also involves intensive cleanup. This is very important if you decide to use aluminum oxide during the blasting process. This substance is composed of very tiny grains and is especially durable. You have to make sure the aluminum oxide is completely removed from the area before you start utilizing the building or surface again.
Media blasting on very tough surfaces involves the use of silicon carbide in many cases. This is a very harsh material, but you don’t have to blast the surface for a long period of time. You can also enjoy the benefit of lower costs for media blasting if you use silicon carbide. If you want a special finish on the surface, it’s a good idea to use steel shot or steel grit. These materials are softer than aluminum oxide, and if you apply it to an etched surface it will be easier to paint on the surface. Dry ice sandblasting is also an option. This is a new method and involves compact dry ice pellets that are shot into a jet that used air that has been highly compressed.
Media blasting is likely a great option if you’re getting rid of graffiti on the surface of your home or business. You can also ask media blasting professionals about special paints and covering to make graffiti easier to remove in the future.
