I am about to sell a house I have been renting out. It just had some foundation work done and part of that was in an unfinished part of the basement. This utility room is large, has two finished walls, and two walls that are poured concrete. It also houses the washer and dryer and these are also walls that are most susceptible to water.
I normally wouldn't think about painting but I was told by my foundation guys that the city has a new requirement for hairline cracks - must be covered in epoxy. I have three or four of these (been there since I bought house years ago) and just some really ugly looking walls right now that are a cross between fixed cracks, dusty and dirty. My stager has strongly strongly suggested that I get this painted.
What are the pros and cons of painting these walls and given that there could be water issues what paint should I use?
I have my own ideas and perspective so please be specific on reasons and materials. (note that the foundation does have a lifetime warranty that I will pass to new home owner and any paint will not negate that)
Also I do not want to cause future home owner any issues so this isn't a flip and dump job.
