Abrasive blasting Essex service

Abrasive blasting, also referred to as sandblasting, is the process of using abrasive materials accelerated through a blasting nozzle. This method can be used in a number of different industries due to its diverse nature, including surface preparation before painting, bonding or other coating operations, removal of rust, scale, sand or paint from fabricated or roughening of industrial gas turbine engine.

There are number of abrasives that can be used for this treatment including:

● Steel shot

● Steel grit

● Glass beads

● Crushed glass

● Aluminum oxide

● Silicon carbide

● Plastic

● Walnut shell

● Corn Cob

● Baking soda

● Ceramic grit

● Copper slag

The term ‘sandblasting’ was commonly used in the past because sand was the only material used during the process. However, knowing the dangers of sand when exposed to it, there have been other materials and grits developed. Therefore, this means that there are many new and improved methods of sandblasting:

Silica Sand

Silicon Dioxide, otherwise known of silica sand, was commonly used to remove impurities from surfaces. This is because sand particles are almost the same size and the edges of the particles are sharp, making it an effective and efficient abrasive material. However, as discussed above, this is no longer a popular choice after health implications arose.


Unlike common sandblasting, using baking soda or bicarbonate of soda is a safer way of preparing a surface. It can be used as an abrasive to remove rust from metals without causing depression or damaging the metal beneath the rough surface. It is also a great material to use on delicate materials that may be destroyed by tougher abrasives.

Steel Sandblasting

Typically, steel grit is used as an abrasive in removing paint and rust from steel metals. This is due to the steel grit leaving a smooth finish. Of all the sandblasting methods, steel grit is often preferred as it is fast cutting.

Glass Bead

If you’re looking for a matte and satin finish for your surface, glass bead sand blasting is the best. As this material is a very fine material, glass beads are able to polish the surface of the object being sandblasted. It is often used to polish cabinet surfaces.
