Last night I put the first coat on the inside of keel potable water tank. I got up this morning to apply another coat and the stuff is still a little tacky. How long does it to cook off? What is the recoat time? Thanks
the time depends on the temperature...the warmer it is the faster the cure time...the colder it is the longer it takes. the temperature makes a really big difference.
The Recoat / Cure Time is 3 Hours* @ 70°F (21°C)

Recoat/Topcoat Maximum time @70°F (21°C)
Amerlock 2/Amerlock 2 - 1 month
Amerlock 2/Amershield or 450H Series - 1 week
Amerlock 2/Amercoat 5405 - 1 day
Amerlock 2AL/Amerlock 2AL - 2 weeks
Drying times are dependent on air and surface temperatures as well as film
thickness, ventilation and relative humidity. Maximum recoating time is highly
dependent upon actual surface temperatures - not simply ambient air temperatures.
Surface temperatures should be monitored, especially with sun-exposed
or otherwise heated surfaces. Higher surface tempertures shorten the
maximum recoat window.
Note: If maximum time is exceeded, roughen surface. For topcoats (finish
coats) not listed, see Product Data sheet for specific topcoat time limitations.
