John,
My list of Pros and Cons comes from experience I believe we've used 'em
all....
a. ESD Tile Flooring
Pro: Looks real spiffy
Con: Cost more than you can imagine
b. ESD Wax, over cement flooring
Pro: Low cost
Con: Maintenance
c. ESD Paint, over cement floor - with or without wax.
Pro: Cheaper than tile
Con: Costs more than wax/maintenance
We use unfinished (no wax or paint) bare concrete in our
assembly/manufacturing area. When the environment is kept within 20-70%
humidity, our typical flooring resistivity is 10 to the 5th Ohms/sq which
is great to dissipate a charge to ground. It doesn't look as sharp as the
ESD tile we have in another area, but it didn't cost us a dime either.
