Vapour blasting, also known as wet blasting or slurry blasting, is a surface cleaning and finishing process that uses a mixture of water, abrasive media, and compressed air. The process involves spraying the abrasive media and water mixture onto the surface at high speeds, which removes dirt, rust, paint, and other contaminants. The water acts as a lubricant, reducing the heat generated during the blasting process and preventing damage to the surface.

Vapour blasting is commonly used in industries such as automotive, aerospace, and marine for applications such as restoring metal components, cleaning engine parts, and preparing surfaces for painting or coating. It provides a gentle and precise cleaning method while also achieving a smooth and uniform finish.
