What are the criteria for selecting coatings for application during extreme (atmospheric) heat?

From Jay Barstow of Aeroflor Coating Services on June 18, 2012:
     Pot life for one (pre-cool). Heat can be good in that it reduces viscosity and increases wet-out, but if the substrate is concrete, trapped air can off-gas (coat in cool-down cycle), or solvents can flash off the surface too quickly, leading to entrapment (especially prevelant in windy conditions). Recoat window can be shortened significantly as well (check data sheet). In addition, my guys sweat on the substrates as well, which makes me none too happy.

From Jeremi Day of Allphaz Inspection Services on June 11, 2012:
     Surface temperature is what is used to determine service life, cure times, overcoat or recoat intervals, service compatibility, etc. Therefore, selection of coatings should be based on surface temperature rather than atmospheric temperature. The selection should, however, take into account the atmospheric temperature to identify pot life limitations, LEL limits, and the general characteristics of the coating and how it will react in certain atmospheric conditions, such as whether or not to use tropical cure formulations of the product as apposed to cold cure versions. More clarity to the question is needed, in my opinion.
