Yes. It is a specialty system, not an additive you stir into a standard floor.
An ESD floor works as a circuit. Conductive fillers run through the coating and a copper ground grid is laid into the build and tied to building ground, so a charge that lands on the surface has somewhere to go instead of sitting there waiting for a board.
The grid is the part people skip and it is the part that makes it work. Conductive material with nothing to drain into is just expensive epoxy.
Resistance gets measured during the install, not assumed. Values are recorded against the spec the room was designed to, which is what an auditor asks for when the room is qualified.
