Rain the day after is not usually an issue (not great to pour DURING rain though as it can effect the mix). It actually prevents the concrete from drying out too fast. I have seen people watering their concrete the day or two after it was poured in the summer to avoid it drying too fast. I had a driveway poured three weeks ago and believe me I was so nervous about the weather when it was poured as we had just had a few hot days, but day it was poured was a bit more moderate and we got some rain next day (and I was very happy). Don't hold me to this as I am not a concrete pro, but I am familiar with concrete driveways and such. This looks like efflorescence. Concrete takes time to cure. As it cures, salts come to the surface (the salts would be whatever was in the water, sand, or gravel that is in the mix) and show as white spots like this. If this is indeed it, it does not affect strength or anything, it is aesthetics only. I have some of these showing up too. If it has been a couple months since it was poured, you can remove them with a concrete efflorescence cleaner. As for sealing...if you "must" depends on your climate and how your municipality deals with winter. Where I am we are told to seal every fall with a penetrating concrete sealer as the salt/sand mix used by the City for the roads is brutal on concrete. We are actually required to in order to maintain our warranty. Really, I would do it anyway as it does lengthen the life of it :)

Yes I have spent hours looking at pictures. But many do not list the color, and sometimes the same color shows very dark or very light or different in different pics. So I was hoping people could post their pics and describe the name, and describe if it looks darker or lighter than the picture in real life. I know our monitors are all different. The bonus of real live people vs landscaping photos from 2009 is immeasurable to me. Many online pics are mislabeled, this I know because I see the same pics with different concrete names listed in different places. Thank you Jeffrey Grenz for your helpful comments. Especially 160 fading. It helps me eliminate something. More comments are welcome. 641 is sequoia brown, Yosemite Brown and Flagstone Brown and in my top picks I see 5084 which is Omaha Tan, Harvest Gold, and Spanish gold. Mrs S, if you are asking, I have narrowed it down to: Coincidentally most of the ones Jeffrey mentioned above: Yosemite Brown (too brown in some pics) Harvest Gold Spanish Gold San Diego Buff (? too close to gray) Sunset Rose (lighter amount of 160) Baja Red (too red in some pics but may fade since 160) Salmon (too red/pink in some pics) Our landscape gravel is a brownish tannish pinkish red called Santa Fe brown here, and there is some red brick pathway nearby. Judy, any follow up comments are welcome. Mrs S, more comments are welcome. Yes I left a message for the concrete contractor to point me to some real live examples of colored concrete. And asked if he knew the color name of some city owned sidewalks that I like. I have been told the actual concrete when poured and dry appears/is lighter than the small samples? lafdr

Contact the company that installed your driveway with this question. They should solve your problem, as their service should have a warranty period. I wouldn't say I like working with irresponsible companies which do not fulfill their duties. Many businesses initially propose a specific time period, but in the long run, fail to achieve it. I like driveway pavers who use the best types of equipment so that the work is accomplished quickly. I turned to paving contractors dublin for help. They did their job 100%.

I wasn't told anything about watering. It rained heavily yesterday though and also rained on Wednesday morning. The garage was installed on Tuesday. I just sent the contractor a question asking if it needs to be watered.
