Newly stained concrete floor -- blushing? keeps turning chalky white
We have a newly concrete stained floor for a house we're building that's been sealed and even after we continually mop it, the floor will very quickly just attract some kind of dust that whitens the color of the floor. Does it need to be re-sealed? Any ideas? Someone said that it's "blushing", but I'm unfamiliar with what that is or how to fix it.
