The Process Of Sandblasting Glass 

Sandblasting is a relatively simple process that can be used to create a variety of effects on glass surfaces. From frosted glass to dot matrix patterns, it can enhance any application. There are several different abrasives available that can be used for this process, including aluminum oxide and silicon carbide. Both have advantages and disadvantages for different applications. 

Purpose 

Glass can be sandblasted to provide extra privacy, insulation and more. Anything from windows, doors and partitions to balustrades and mirrors can benefit from this process. Sandblasted glass is also an excellent choice for achieving anti-slip resistance to glass panels and walkways. Sandblasting is an effective way to create custom glass pieces with unique designs, patterns and even words and logos. It’s a great option for improving the aesthetic appeal of storefronts and office windows. 

Safety 

Whether you are sandblasting glass to etch it, paint it or remove a coating, there are several safety measures that must be taken before starting this process. Regardless of the materials used, sandblasting is a dangerous process that can cause serious injuries and health problems to the workers and others in the area. This is why it should be done in a controlled environment by trained professionals. Besides using the proper equipment, all blasting workers must wear protective clothing and respiratory equipment. 

Equipment 

A complete system for sandblasting glass requires three main pieces of equipment: an air compressor, a blast cabinet, and a blasting abrasive. It is also recommended that you wear a blast hood and steel-reinforced boots while using your blaster. The key to a successful blast is managing the intensity of the spray and the direction of the nozzle. 

When sandblasting glass, most people use abrasives such as aluminum oxide or silicon carbide. These materials are very sharp and hard. However, overuse can cause them to produce a fine dust that can make it difficult to see the work and cause static electricity to collect on the glass. Another popular abrasive is recycled bottle glass, which contains less than 1% free silica. This abrasive is also chemically inert, non-reactive and SSPC Class A approved. It is a good alternative to OSHA-regulated silica sand for abrasive blasting on construction sites. 

Cleaning 

Sandblasting uses a variety of abrasive media to clean and prepare a surface for treatment or finishing. It is a common process used in industries such as auto part manufacturing, shipyards, and powder coating. The abrasive media is propelled at high-pressure through compressed air. This cleaning and preparation procedure is used on almost any surface to remove paint, rust, corrosion, and other contaminants. 

Traditionally, sand was used as the abrasive but now there are many other environmentally friendly options to choose from. These include crushed glass, steel grit, aluminum oxide, garnet, plastic beads, and walnut shells. Regardless of which abrasive you choose, be sure to wash the surface thoroughly afterward. This will remove any remaining abrasive media and will help to ensure the full etched effect is not lost on the finished product.
