Question
Will spray foam stick and expand properly on cold ductwork that is condensating?
 
Answer
SprayFoam.com

When applying spray polyurethane foam, all surfaces must be absolutely dry. Condensation will be detrimental to the physical properties of the resulting foam. Regarding temperatures, each system has temperature limitations. Check with your manufacturer to make sure you have the right system for the job.
