^ Yeah, actually, I agree with what you're saying. It's not as far-fetched as it sounds, as terrible / excellent as that may be.

Sorry if I sounded snide in my last post.
Most of the sealing bit is pure myth. In some cases, it can actually do more damage than good.
There are many, many factors that govern whether or not concrete will be a good performer in the elements, including mix design, cover, admixtures, orientation, and type of reinforcing. Most of the painted concrete high-rises in Chicago do not need paint for structural performance.
Now, on your second point, I agree with you: Given the nature of the concrete at Waterview, there is a good chance that one would like to protect it from the elements. But we cannot say that without knowing more specifics. I think if the exposed bars are kept from corroding, the structure would probably suffer almost no damage for the next several years. Pooling on slabs would be the biggest concern, and I don't know how much paint would really remedy that, since not all are pitched.
