To sandblast something is to propel a fine mist of grainy materials at the surface at a high velocity. It is used to clean or etch the surface. The process is performed by a trained sandblasting professional who might also handle things like insulation and other maintenance issues. Originally, sand was used to complete the task. However, the use of sand resulted in lung disease because the tiny particles were inhaled, so alternative materials had to be used instead. As long as the particles are small enough, materials like copper slag, steel grit, and coconut or walnut shells can be used. Though the danger is not as severe, particles can still be inhaled, so the process needs to occur in a controlled area. Professionals usually wear protective clothing and might use an alternative air supply during the process.

The process first became popular in the late 1800s. It was originally used as a cleaning method, but also to prime surfaces for painting and sealing. It is important to blast away imperfections before applying a layer of paint and this was the ideal solution. The surface is left smooth and clean after the blasting process and all that needs to be done is a quick wipe down before painting. It is used on small surfaces like fences and large surfaces like ships and bridges.

To perform the process, several tools are needed. These include an air compressor, a blaster nozzle, and the actual abrasive materials that will be blasted. If a piece is small, a small workstation is usually enough. When the process is performed on glass, you will need something to hold the glass in place. Regardless whether you are cleaning or etching, you will need to prepare for a lot of cleaning up once the job is complete.

When used in etching, the abrasive is applied to the glass until the surface is somewhat opaque. If you are trying to see through etched glass, you will see shadows, but not details. This process is sometimes calling snowing or whiting. It can be used to create designs, letters, writing, or images. The speed at which the blasting occurs can be adjusted to create different shades. The angle also makes a difference, which is why it is important to take a piece to a professional blaster when etching, especially if a design is intricate. The process can be very detailed and using different angles and depths will make a big difference in your final product.

Blasting equipment comes in all qualities and in all price ranges. There are small at-home kits available that allow you to etch glass for craft projects. This is usually the least expensive option, but it is very basic and only appropriate for small projects. More complicated equipment used by professionals is expensive and requires a great deal of accessorizing. Using blasting for cleaning is usually a large scale project and often left to professionals. If you believe blasting might be right for your project, contact a professional today.
