Above data just for your reference, the actual drying time depends on film thickness, ventilation, humidity, primer, mechanical strength etc.

Surface treatment：

l Get rid of salt and other water-soluble contaminant with clean water
l remove grease with approperiate detergent
l ensure the surface being clean and dry before application
l pay attention to the recoating window
