What finishing defect can occur when the paint room temperature is too warm?

When the paint room temperature is too warm, pinholes or blisters can form during the drying process. High temperatures can accelerate the evaporation of solvents in the paint, trapping gases and moisture beneath the surface of the coating. As the paint dries too quickly, these trapped substances can create bubbles (blisters) that rupture, leaving pinholes in the finish.

This phenomenon is particularly problematic as it leads to a compromised surface that can be difficult to repair. The presence of pinholes or blisters not only affects the aesthetic quality of the finish but can also reduce protection against corrosion and other environmental factors. Therefore, maintaining an appropriate temperature in the paint room is critical for achieving a smooth, durable, and visually appealing paint job.
