SURFACE PREPARATION
Concrete substrates must be suitably prepared using mechanical or abrasive blast cleaning techniques such as scabbling, needle gunning, grit blasting and to provide a clean, sound surface free of laitance, surface contaminants such as oil and grease and loosely adhering particles.
MIXING
E.M. BOND should be mechanically mixed using a forced action mixer or in a clean drum using a drill and paddle. A normal concrete mixer is NOT suitable. Mix E.M. BOND with water to produce a gauging solution in the correct ratio for 90 seconds. Add gauging solution to cement/aggregate mix until desired consistency is achieved.
