Dave, concerning the report you read about the curing/drying issue . . . .
there are several situations that will prevent any coating from drying/curing properly:
temperature
humidity
contaminated surfaces
incompatible thinner
incompatible primer
painting at 70 degrees then the temp drops to 45* 4 hours later
improperly mixing two-part components
appling coating thicker than the manufacturers suggestion.
and probably many more
read, understand and follow the instructions on the label
of all products you may use. Observe all safety precautions,
and you will have satisfactory results.
Just because your weather is warm when you apply the coating,
and the temps drop below 50* within the next 8 hours, you could
experience the tacky, uncured finish.
70* degrees for a consistant 12 hours should give you a good drying time.
looking forward to your painting project !!
I have been considering the Sea Hawk two-part epoxy primer for my next project.
But finding any sort of usage data is hard.
