North Devon Shot Blasting
Differences between grit blasting and shot blasting?
Sandblasting is often used to describe the many different methods we can strip, prepare, clean up or even remove the surfaces of materials. Although sand has been banned from usage for some time due to the dangers of silicosis, there is still a range of safe mediums to help create a perfect finish.
Other than people using the term sandblasting, the two most common types of blasting which are talked about are shot blasting and grit blasting. Both techniques use different materials as an abrasive but are nearly always put under the umbrella of “sandblasting”, to describe their purpose.
Its name is due to the fact that tiny steel balls are used, steel blasting is performed using the tiny balls or through crushed steel, sometimes referred to as “peening”. Shot blasting is best suited to metal materials such as cars, truck bodies, steel beams etc. when you wish to remove layers of rust, loose materials, paint or dirt. Due to its heavy-duty nature, it is also used to prepare surfaces through abrasion; you can create a great surface for painting.
There are a wide variety of materials that can be used to perform grit-blasting, depending on the surface you wish to work on. Each one has its own unique merit when preparing different surfaces and for different finishes. Used mostly to smooth down surfaces and walls, it can also be used for graffiti removal! Silicon carbide, Alumina and even walnut shells can be involved in the
process of grit blasting, these materials will protect your surfaces whereas shot blasting would be too excessive. At CES, we use both of these versatile blasting techniques either through air(sandblasting), liquid lasting, vapour or dustless blasting.
