Carpet tile over more of the same epoxy finish? (short pile, single neutral colour, so it doesn't 'hide' dropped small parts and components) If you spill anything nasty in the 'clean' section, being able to replace a tile or two* rather than having to attempt cleanup then deal with the remaining damage is worth a *LOT*. The EEVBLOG Lab has just been re-done in carpet tile after the flood - If its good enough for Dave . . . .
* As we found out when one of the shop cats got into the bin and ate the remains of the boss's Falafel dinner then had a bad case of the squits, a metre inside the front door, which we discovered 9AM Monday morning half an hour before an important client meeting. Boss was tearing his hair in horror, till I said I'd sort it. "I'll need a bin bag, spare tiles, a flat steel scraper to lift the tiles, spray glue, and a can of air freshener and in five minutes you wont know it ever happened!"
