What is the minimum temperature differential required to start coating?

The minimum temperature differential required to start coating is established based on ensuring proper adhesion and performance of the coating material. A temperature differential of 5 degrees Fahrenheit (or Celsius), above the dew point, helps to prevent condensation on the surface. This is crucial because if the surface temperature is too close to the dew point, moisture can form, leading to issues such as poor adhesion, blushing, or corrosion under the coating.

This 5-degree differential creates a suitable environment for the coating to be applied effectively without compromising the integrity of the application process. Maintaining this standard is essential for quality assurance in coatings work and helps to ensure the long-term success of the coating system.
