Media blasting is a very gentle form of abrasive blasting where sodium bicarbonate (Sodium hypochlorite) is blown against a hard surface with compressed air. It has a less powerful abrasive effect than fine sandblasting. It was first used in the preservation-restoration of the Statue of Liberty during the 1980s. Its more popular name is “brush blasting”. Prior to the popularity of this media blasting method, other methods such as sandblasting and electrode positioning were used. Brush blasting techniques are used in many industries and all types of surfaces can be affected.
Brush blasting from this homepage removes minute amounts of material from a rough or flat surface. It has applications in manufacturing, construction, painting, polishing, flooring, and woodworking. For example, it can remove minute amounts of metal shavings from a diamond plate, smooth stainless steel, or clean and polish a marble that has been etched.
In the manufacturing industry, it is often used for bumpers, cases, and tool cases. It removes a small number of materials that cause surface rusting, friction, and improper tooling. It is also used to remove burrs from product surfaces and to repair dents. Since it removes surface rust, it increases the life of your bumpers, cases, and tools by reducing corrosion and the buildup of carbon contaminants on your products.
In your woodworking projects, it can be used to sand a rough or dull surface to a smooth finish. There are two methods used in media blasting. The first method is called cavitation sanding where the workpiece is placed in a pan of water. The workpiece is then dropped in a buffer filled with sand at a shallow angle. The water evaporates, leaving the sand at the top of the buffer. Look for more facts about pressure washing at http://regularshow.wikia.com/wiki/File:S5E31.007_This_is_a_pressure_washer.PNG.
The other method of media blasting involves the use of high-pressure water jets. The water jet is directed at the workpiece while still in a pan of water. A fine spray of abrasives and chemicals is then used to remove the dirt from the surface. Both methods of this process are effective for graffiti removal and paint stripping.
In terms of paint stripping, high-pressure washing, and acid stain removal, it can effectively remove the paint from an existing surface. For example, it can remove the red color from a freshly painted wall. It can also remove oil stains and grease buildup from a carpet or rug. These methods are suitable for cleaning purposes. However, it should be noted that these techniques are not appropriate for removing paint chipping or cracking. If you want to apply media blasting to repair scratches on your walls or to polish your surface, then you should follow professional guidelines such as those found in How-To: Home Improvement Guide, Fourth Edition (PHS Press, 2021).
