Sandblasting Basics Blast Away the Confusion

Sandblasting involves shooting glass beads, or some other medium, at high velocity across a rough surface as a means of smoothing the surface. This happens because the medium rids a surface of its current finish. The operation can also be used to remove rust, and to ready a surface for a new coat of paint. The media used depends on the surface being treated. No matter the surface, it is best to begin with a gentle medium, because it’s not always certain how much damage a certain component can impose on a surface.

Soft Surface Treatments

For soft surfaces, walnut shells are a great option. They are not abrasive, and they are also biodegradable. Corncobs are also an effective media because they are biodegradable and barely mark the surface being treated. Glass beads are another high-quality medium to consider. They can be recycled numerous times, and they create a bright, soft surface. Aluminum oxide is a choice that leaves a superb finish that looks subdued. However, the use of aluminum oxide demands a special, detailed cleanup so not as to impact the environment, and to keep up with codes.

Hard Surface Treatments

The hardest sandblasting component is silicon carbide. This choice must be used on areas that can withstand a great amount of intensity in a short time period. Steel grit or steel shot adds a nice finish to this type of job, making the surface look refined and durable.

Car Treatments

Cars require specialized media because the materials used in their production can be easily warped or dented. Just think of what happens in a fender bender, and that provides a good idea of what can happen if the wrong elements are used when redoing an auto surface. The best options for automotive treatments are acrylic, melamine, polyester, and urea. These elements will not damage the materials used in the auto-design. Other materials most certainly will cause damage, and those damages may be significant enough that a new car needs to be purchased.

Dry Ice Function

Dry ice is one of the newer methods on the market. It is used to clean heavy machinery and electronic systems by shooting dry ice pellets at a high speed across these massive surfaces. This method can make machinery look brand new by stripping away rust. It also helps keep machinery running smoothly.

Understanding how sandblasting works, and the commonly used materials, will help you choose the right professional to hire.
