To make it easier to understand for our clients, we are here to compare the most popular methods that we use; sandblasting and shot blasting.

What is Sandblasting?

Used by a number of industries, sandblasting is a common surface treatment which uses abrasive materials to clear the surface. Typically, the abrasive material (often steel shot; steel grit; glass beads; walnut shell etc.) is accelerated through a blasting nozzle via compressed air and onto the surface itself.

Sandblasting can be used to remove a number of blemishes to a surface such as:

● Removal of paint; rust and other pollutants.

● Shaping small parts that have small burrs or irregularities.

● Clean streets; pathways and other concrete surfaces.

Benefits of Sandblasting –

● Sandblasting is often regarded as the fastest and the most efficient method of removing paint from a surface.

● Sandblasting is also the most convenient and the most cost effective method of using contaminants such as rust.

● Often, a metallic surface may need to have the surface profiled so the subsequent coating can be applied – Sandblasting can do this.

● Sandblasting has a wide range of uses compared to other methods, meaning it can be used on rust; paint; graffiti and stains on wood etc.

● While sand used to be the material for sandblasting, it can cause damage to the body so there are number of other less harmful substances used such as coconut shell; walnut shell; copper slag etc.

What is Shot Blasting?

Unlike sandblasting, shot blasting is used only in industries specific to metals such as aerospace; automotive; construction etc. It is used as a similar method to sandblasting, by rapidly impacting a surface with abrasive materials like steel shots; chilled iron grit and steel grit. However, the procedure uses a turbine which turns quickly and separates the material.

Benefits of Shot Blasting –

● Shot blasting eliminates the usage of non-eco friendly and harsh chemicals through the process i.e. silicon dust.

● Shot blasting offers higher production rates; a wider abrasive selection and better blast pattern accuracy than other spraying methods.

● The finished surface is completely free from chemical deposits; scales and dust content, meaning it doesn’t remove the original metal when removing scales on the surface.

● Shot blasting is able to form a bond between the protective coat on surface such as zinc; paint or epoxy and the shot blasted surface.

● It also helps to detect any surface faults or defects.

● Shot blasting increases the longevity and durability of the protective surface coats as the coat adheres better to the cleaned and scale free surface.
