Temperature To Handle To Recoat Immersion
75°F (24°C) at 4.0 mils 100 microns) 6 hours 16-18 hours• 5 to 7 days
75°F (24°C) at 12.0 mils 305 microns) 11 hours 16-18 hours• 5 to 7 days

Curing time varies with surface temperature, air movement, humidity, and film thickness.
• Maximum recoat time with itself is 7 days. Extended maximum recoat time of 14 days is allowed when used as a primer for Tank Armor products. If recoat time is exceeded, the coated surface must be scarified before topcoating.
