Moisture within SPUF System
I have specified a Urethane Coating System for an aging SPUF system.Contractor believes that some moisture is present within foam system. He is afraid that coating will trap moisture and become vapor blisters under the new coating. This roof is not leaking. I believe there is some moisture in system - but how much is too much? We are restoring system to prolong life - don't want to create problems by coating... Is there a vent system that could be installed with the coating or would that be a waste of time? |
