This system will propel an abrasive at a high velocity from a blast wheel onto the work surface. The blasting action is contained within a work chamber fitted with a unique combination of seals which ensure efficient recovery of the abrasive via a separation section of the abrasive storage hopper. The linked dust collector ensures a dust free operation leaving a textured concrete. The substrate is mechanically prepared and will provide a key to all screeds and toppings. Laitance can be removed to yield a tougher and highly acceptable surface.
