Setting the surface temperature 5 degrees above the dew point helps ensure what condition?

• A. A dry surface
• B. Faster cure
• C. Increased gloss
• D. Stronger adhesion

Answer: (A)

Keeping the surface temperature about 5 degrees above the dew point prevents condensation on the surface. When the surface is warmer than the dew point, the air near the surface can’t reach saturation, so moisture doesn’t condense as liquid film. That means the surface stays dry, which is essential for proper coating application. Is there any faster cure or more gloss or stronger adhesion just from being above the dew point? Not directly. Dryness helps the coating form correctly and prevents moisture-related defects, but cure rate, gloss, and adhesion depend on other factors like chemistry, temperature, and surface preparation. The key outcome here is a dry surface, free of condensation.
