Vapour blasting, also known as aqua blasting or slurry blasting, is a wet blasting technique ideal for cleaning materials such as Aluminium, Bronze, Magnesium, Titanium, Brass, Copper, Steel, and Stainless Steel. This gentle process cleans surfaces without damaging gasket faces, making it safe even for carburettors! It results in a consistent satin polished finish and lightly peens the surface, which helps reduce porosity from casting or previous corrosion while relieving surface stresses.
This finish is easy to maintain; aluminium, in particular, appears “fresh out of the mould” and provides a desirable look for items like untreated engine casings. Additionally, vapour blasting serves as an excellent starting point for achieving a highly polished finish or applying protective coatings.
