Strange Concrete Coloring

[s_blaylock]

This house I just moved into was built in 2014. The original concrete that was poured for the sidewalk, driveway, and back patio all have this strange coloring and pattern on it. You can see it when its dry, but shows up better when its wet. Anyone have any idea what it could be from?







I'm not real concerned about it, just curious. Not sure if a power washer will take it off or not. Haven't tried that yet.

Thanks

Looks to me like someone did some chalk art on it. That's the residue from it. Probably will power wash off but may take some scrubbing with some cleaner to get it completely off.

Maybe it was covered as it cured !

All of the areas of concrete have this same coloring?

If so, then it would almost appear that the previous owners had the coloring put in it on purpose.

I can't imagine this would happen just on it's own. I think it actually looks pretty cool!
At least you have a look to the concrete that no one else has!

Looks contrived and I like it. Never seen this design before.

Yeah it almost looks intentional. I dont think its from chalk. I have two little ones and I am well versed in sidewalk chalk. strange for sure though.

looks like crinkled wet plastic ,like they covered the concrete because of rain the day of the pour ......IMO

I was thinking the same thing, like a cheap/old blue tarp perhaps and it bled its color a bit.

i like it, looks cool as long as all of it looks like that.

They covered it with a cheap blue tarp and the color bled in to the concrete.

Not sure about the blue, but the pink looks like the residue that rosin paper can leave if it gets wet. We had a dopey painter leave some on a new deck over a rainy weekend that left a pink mess.
