Hello,

I have contractors blasting and painting the inside tank bottom with Jotun Tank Storage Comp A. However, I need the tank to be in service sooner than expected. The paint has to be applied when the RH is < 85%. The various drying times reduce as the temperature increases.

Are there any innovations I can employ to the inside of my tank to drop the humidity and increase the temperature at night, so I can paint at night? I do not have access to an industrial dehumidifier. The heating and de-humidification has to be done evenly so as to ensure proper paint application throughout. Anything I should consider?

Control the painting environment. Replace the air in the tank environment with drier air. Look for ways to increase the air temperature, reducing the relative humidity without removing water vapor from the air, buy some air heaters, or by reducing the water vapor in the air by precondensing the water vapor in the air. Tarps raised at night may help to maintain a higher nighttime temperature. Buy some compressed air, as compressed tank air is usually drier than normal air. How much money do you have?
