Sherwin Williams Zinc Clad II has a time to recoat of 18 to 48 hours depending on environmental conditions and a time to cure of 7 days.
Can I get an accurate DFT reading after time to recoat using a positect dft gauge?
Also I have a paint system spec that has Zinc Clad II, Dura-plate 235 and...
We were using x-coarse press-o-film so I believe the values are accurate. Up to 4.5. We got an average of 4.1 mils and we took 18 measurements.
It will be coated with Sherwin Williams Zinc Clad II primer.
I have a specification that calls for a surface preparation of 1.5-2.0 mils.
It was blasted and measured with Press-o-film testex and measures 4.0 mils.
Is more mils better for adhesion? Is this acceptable? What should I know?
