Kerabrade S is installed usually 15mm thick onto a steel shell to delay wear of the shell.  To optimize adhesion to the shell, the plaster is anchored to expanded metal. The preferred grade of expanded metal is Mentex 72. The expanded metal may be raised slightly off the shell. To do this the expanded metal is bent outwards at the desired intervals for welding. To bend it, cut a short (about 9mm) piece of pipe of diameter approximately 55mm. Weld this to a rod about 800mm long. Place the expanded metal on a concrete slab. Slide the pipe under the expanded metal to the point to be bent out. Strike the expanded metal sharply with a hammer until it reaches the concrete. This results in bumps raised about 5mm, which can now be welded to the shell.
