What is Wet Abrasive Blasting

What is Wet Abrasive Blasting?

Wet abrasive blasting has many other names. You may hear the terms:

“slurry blasting”

“liquid abrasive blasting”

“wet honing”

“wet etching”

which all amounts to the same thing, mixing the abrasive materials with water before it reaches the blasting surface.

Wet abrasive blasting appears to be like sand blasting with added water. However, the two processes are entirely different in the way they achieve their finishing results.

There is a variety of abrasive and non-abrasive materials that can be used in wet abrasive blasting. This includes ceramic beads and glass as well as plastic, mixed with water and propelled at a rapid speed on the surface can produce great results.

When using this wet blasting technique, high volumes of water are used to cushion the effects of the material. Which prevents it from becoming embedded in the blasted surface.

Different types of media:

Round media – this includes ceramic, glass bead and stainless steel shot. These materials are used to clean various surfaces leaving them clean, bright and descaled. Metal and ceramic materials last much longer than glass beads.

Plastic angular media – can be used for paint stripping, deflashing other plastic parts and removing types of flash. These can be used in a system whereby the parts are treated with the wet abrasive blasting technique before being blasted with only water and eventually with a drier.

Angular grit media – is a very aggressive substance used for blasting hardened surfaces. It can also be used to remove rust, grease and heavily scaled surfaces. The types of materials used in this process includes steel grit, crushed glass, aluminum oxide and silicon carbide.

Fine angular grit – the finer mediums are useful when you need to clean or de-scale deeply into the pores of surfaces prepping for coatings.
There are many companies around which can provide wet blasting services for you. Please view our vapor blasting services page to find a company near you.

Wet blasting can be used to remove many types of contaminates, de-burr objects and leave them clean, shiny and good as new. It can also be used to detect cracks and other types of faults in highly sensitive engineering and automotive equipment.
