Have a good looking brick wall of Chicago brick in my lounge. It absolutely was mortared with the black mortar. The mortar is Insat about an inch. Use to get dark paneling but now white walls. Could it be possible to re-mortar the brick using a lighter mortar or grout? http://liquidviagra01985.kylieblog.com/7368266/rumored-buzz-on-brick-feature-wall
