Good afternoon, everyone. After many. many years of apartment living in the city, I am moving to the country. My wife and I are purchasing a house with a mostly finished basement, including a wet bar, a full bath, and two rooms to choose from for my electric home brewery. The basement floor throughout is sealed concrete and the walls are drywall. I'm looking for recommendations on affordable treatments for the floor and (if necessary) the walls. The floor will not have any sort of center drainhole. On a related note, I am moving from city water/sewer to a septic system. Is there anything I should avoid using/putting down the drain? Thanks for your help!
