I have a DW from 1994 on a permanent foundation I bought in March and I've noticed on the concrete foundation it looks as though it was painted white? and the paint is peeling off in sheets. I'd like to fix this as it looks bad and probably i can only assume is bad for the home, but i'm not sure if this is paint or if this is a special concrete allweather sealant or what?

Have any of you had this situation - what did you use, what time of year did you paint it, etc? Any advice is appreciated.
