Cement pad exists for 50+ years in a covered breezeway leading to my front door. I live in an area that rarely gets 25 degree weather for more than a week, usually mid-30's and above--and this is a protected area. It's cement gray-color. I'd like to make it a light terra cotta, but not really change the texture or re-do where the cracks have been filled over the years because as it stands would give it a more antique look. It seems pretty solid as a surface. Is there some way to do a "wash" over it? Even a few times, to get some good color on it without changing it's texture? I think painting it would give the wrong look altogether--too solid, not enough "movement." It's a bit rough to the touch, which is good, not slippery. I think it was covered with an indoor-outdoor rug which was not glued down for years.
