Dry blasting or wet blast: what are the benefits?

When it comes to blast cleaning, and the various materials that can be used, it is important to consider all of the pros and cons of your options. Wet blasting, or water blasting, is the most commonly used method.

But why is it most popular?

Wet blasting can strip away a surface – such as rust or grime – just as effectively as sand or abrasive blasting. Dry blasting is restricted under UK law and it is generally known that wet blasting is safer, as fewer particles are likely to be breathed in or pose health and safety or environmental risks.

Wet blasting can also help maintain the quality of the blasted surface, as dry blasting can cause denting and damage to the surface beneath the material. The particles in wet blasting are carried by the water and allow for a much more controlled abrasive process, sliding alongside the surface of the material as opposed to being shot perpendicularly onto the surface. This smoother process allows for a more polished finish, and debris is less likely to be lodged into the surface of softer materials.

There are instances where wet blasting is not appropriate, but it is generally safer, easier and more cost effective to use wet blasting.
