I have an area of about 1000 sq. ft. that has two different colors concretes. One side is red with what looks like a bunch of gravel chips in it and the other side is just regular grey concrete. Does anyone have any suggestions on how to apply stain or some other type of coloring to make both sides a uniform color?Thanks for your help! via /r/DIY http://ift.tt/2xECiSb
