Your ESD thin set epoxy flooring system must be grounded to allow the electrostatic potential to flow to ground. In many cases this grounding takes place when the coating comes into contact with a steel column or any grounded portions of your building superstructure. In the case where a reliable grounding connection via the aforementioned method is in doubts utilize the following

• Locate AC power outlet. Remove electrical face plate cover (typically plastic). Starting at a location about ½” beneath the outlet cutout (on the drywall) run a piece of our 2" wide aluminum foil ground tape down wall and onto floor about 2 or 3 inches.
  Note: for a great looking attachment cut any wall base, peel back base and run strip behind re-glued base.
• Run another aluminum foil strip (about 36” long piece) over this 2" or 3" piece that you've placed on the floor. Run this strip parallel to the wall and stick to the flooring substrate (concrete, vct, etc).
• Lightly wipe down the aluminum strip with standard rubbing alcohol and a clean piece of paper towel. Allow to dry. Paint over this strip with a thin layer of ElectraGuard ESD epoxy.
• Replace plastic AC electrical face plate cover with a metal face plate cover making sure metal face plate cover contacts the aluminum strip.
• Your floor is now grounded
