What is grit blasting?
Grit blasting is a type of shot blasting (also referred to as media blasting) which involves the projection of media onto a substrate using air-propelled technology. More specifically, with grit blasting the type of media is usually an abrasive material. This helps to create a new surface profile to be treated, free of contaminants with an enhanced surface finish. At CLM Fireproofing, we often use a variety of grit blasting methods to prepare surfaces for the application of intumescent paint within a passive fire protection package. During the quotation stage, we study each job to determine which exact process is required. We consider multiple factors, including site conditions and the specific materials being removed.

What is dry grit blasting?
The term ‘dry grit blasting’ refers to using a ‘dry method’ such as propelled air to project media onto a surface. This is used for most surface shot blasting operations, reducing the need for additional surface preparation prior to the paint application. However, there may be times when a water-suppressed blasting system (such as vapour blasting) is required. This is usually when there is a risk of creating airborne dust during blasting, which can affect other on-site operations. In this instance, the water or vapour particles act as an additional barrier for the abrasive media, preserving the blasted surface.
AS Blasting and Coatings and CLM Fireproofing takes pride in implementing tailor-made blasting methodologies, ensuring a safe and efficient on-site environment.
