Howard, Test the tile before destroying. We have learned some flooring will work as ESD flooring, although it's not marketed as such. If you must install something, I would suggest an epoxy slurry floor coating. The material is applied at 0.090" thick. Can be applied over nearly ANYTHING. It fills cracks and small voids. They can add the appropriate fixtures for grounding, as needed. The finished product is durable enough for fork lift traffic. The surface is non-slip, even wet. Installation was done over a weekend and it took 4 days to fully cure. Cost was around $2/sq. ft. I believe it was a 3M product, it was several years ago.

Dear TechNetters, Our PCB assembly area is being consolidated to another building, and I have the opportunity to request some type of ESD floor coating over an existing non-ESD tile flooring. What are your opinions on the best, most reliable, and of course cheapest, method of ESD flooring? I am thinking that removing the existing tile would not be a cost effective alternative. We are moving out of a facility that had no ESD flooring, so improvements should be easy to achieve. Thanks for the assistance.
