How much detail should be included in a specification for the surface preparation and painting of a parking garage exterior that includes tilt-up and structural concrete substrates?

Selected Answers

From Murray Schomburg of QA5 LLC on January 6, 2011:
Along with all the standard surface prep for these concrete surfaces (and I do not know how old the concrete is here that we are talking about), we should replace/repair and patch any spot aggregate pieces containing ferrous materials that have already started to rust, and stain the surface. I don't feel comfortable with just a cover-up type operation in these locations. I know that this bad aggregate spotting is a rare occurrence, but correct surface prep is important if we want a lasting finish.

From john lienert of nehalem bay painting co. on December 13, 2010:
Cure time (both concrete and finishes), PH testing before any application of finish.
