My darkroom is in the basement, and has a painted concrete floor. Being a basement, there is most always some humidity, which helps. I have a little Shark vacuum I use before doing anything. I also keep Reilly, my Corgi (he's my avitar) out (most of the time). When printing I use an anti-static cloth on the negatives and enlarger carrier. I also have hand held ion generator that helps, especially in the winter.
Cleanliness is important!
