Re: ESD flooring
Epoxy could chip out. Tiles are a little easier on the feet. We have interlocking tiles for our ESD floor in the Fabrication/ESD area. Used to have ESD carpet tiles, but what a PIA to install. You needed double-sided adhesive underlayment sheets with copper striping. Also, hard to keep clean and good luck finding small parts dropped, like tiny screws and washers.
Our tiles now are more like regular flooring tiles, but much thicker, interlock with only a rubber mallet and require no foundation or underlayment.
Unlike epoxy, fully removable.
