I recently had a concrete patio area, about 450 sq ft, replaced due to some drainage and cracking issues. I thought that since I was spending the money, I might as well spend a bit more and do a stamped concrete. I used a respected company based on a lot of research. The job was just finished and the powder coat was removed. To our suprise the color was much lighter than anticipated. We used a slate stamp and wanted a dark grey, almost charcol. Some of the edges appear to be this color but the majority just looks like normal concrete color with a stamp. We have not talked to the company as this just occured on Friday. Any idea what options are left to get this darkened? Will sealing the concrete provide any type of darkening, as I noticed the color looks great when it is wet and thought a sealer might enhance or darken? Any help would be appreciated as I will be discussing this with the company on Monday.
