For fast scaling of decks the walk behind SF11 is a fast, effective means of removing hard coatings and corrosion. 11 carbide tipped heads quickly fracture even the toughest materials, perfect for on-going maintenance or preparation pre blast cleaning to speed up removal and save costs on abrasives. The floating head design allows the SF11 to easily follow deformations in the surface meaning coatings will be removed evenly and consistently.
