In years past have done lots of concrete work, but never a stamp and stain job. Overall will be 30 yds involved, three different pours. I've done research, but can't decide staining while wet, or do it later. I need tips on screeding, troweling, what slump, what kind of day and time of pour, how to do the acid stain, and when. Also planning a picture of a large compass stained in (have a professional artist in the family) any tips there? I have the stamping pads and planning on a bronze like finish. Just a wore out carpenter here, thats wanting to put a little flash on for my criticizing inlaws.
