Shot Blasting Metal

Shotblasting is a method used to clean, strengthen (peen) or polish metal. Shot blasting is used in almost every industry that uses metal, including aerospace, automotive, construction, foundry, shipbuilding, rail, and many others.

floor surfaces

Shot blasting means that a machine projects a large number of small steel balls towards the surface of the floor and this way crush the surface. Most of these balls are then drawn back into the machine to be used again. However, some of balls usually slip out of the system and can damage the environment. Shot blasting also damage the remaining surface making it impossible to get a completely flat and leveled surface. Instead, self-leveling compound is required or that the floor is grinded.

Grinding replaces shot blasting

Today, shot blasting is largely replaced by grinding in many countries and within the next few years we believe that grinding will have replaced shot blasting all over the world.

GWS recommends grinding instead of shot blasting in all floor preparation.
