Spotted section on the left (sunny most of the time) and consistent color and closer to the color, but darker, I wanted on the right (shady all of the time)
How do I correct black spots on stamped concrete?
+6
I had a stamped concrete patio installed a couple of weeks. The color was lighter than I thought it was going to be but the most disappointing thing is there are black spots (attaching pics) I knew there would be variations but this is extreme. There is also a drastic color difference between the areas that are always in the shade and the areas that are always in the sun.The contractor and I are in discussion mode but he keeps telling me that it will be uniform in 2-3 months ... but I cannot see that happening. I will admit it has lightened up a little but it still looks bad. Can this be fixed? Can the color be changed to be more of what I desire? If so, how can this be accomplished? I want to have as much information as possible as I continue discussing the situation with the contractor.Thanks in advance for all your help.Best Regards ... Robert

This is exactly why I don't like stamped concrete. It always looks dirty to me with these dark/black markings. Every job Ive seen they all appear with these black marks the same regardless of what color used.
You need to wait at least 30 days for the concrete to "cure" then decide what you want to do. Stamped concrete is pretty, but can be a maintenance headache too. Just depends on how fussy you are and what your expectations were to begin with.
Are you sure that is not mold? Or did someone walk all over it before the product was cured??
if you are not happy with the results after it has cured, there are concrete paints and stains, I had painted a "rug" on a former patio.
I've never seen anything like this. To me It looks like someone walked on it with muddy shoes so I understand your unhappiness. I have no idea what is the norm but hope it ends up the way you expected.
Hi, call the Contractor back to clean it and re-seal it!
