Blasting is the most effective way of providing a key for superior surface coating adhesion. The process removes unwanted blemishes and redefines the surface with new texture, ensuring that the early stages of the project start with a solid foundation. This is also an excellent way of removing rust and millscale to provide a good clean, profiled surface. As well as chilled iron grit and mineral sand media, other blasting finishes can be achieved by using a range of glass beads to provide aesthetic finishes on stainless steel and aluminium.
Abrasive blasting is very much the pre-requisite to many of Bradleys coating systems. Depending on the specified finish we work to BS 7079 SA 3 of BS EN 13438: Annex B. A good example of the texture and finish of abrasive blasting can be seen on the Bob Dylan Black Buffalo Ironworks project.
This ensures a good cleanliness of substrate along with the required and measured profile for long life adhesion.
