Looking to cover my exposed concrete basement foundation. I am reading that there are cement boards that are built for external use. Saying this, I am wondering if the cement board will need to be covered (Stucco) or something. I would just like to use PL or liquid nails to put it up.. the current color of the basement is grey, so if it looks similar, I am good without painting etc..

I see that there is a hari or durock product for interior or exterior applications. Anyone have any experience workign with this?
