With 15 years of experience, Markwell Peck are a team of commercial decorators who specialise in offering spraying technologies, including our high quality sandblasting service Essex.
As experts in everything from grit blasting to abrasive blasting, we have carried out thousands of renovations in a number of industries; from the industrial sites to educational facilities. Yet for our clients, there is still a lack of understanding about the spraying process that we use.
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.
