Applying a primer specifically designed for adhesion is a common solution for improving paint adhesion on troublesome surfaces. Primers are formulated to bond well with both the substrate and the topcoat, creating a suitable foundation for paint application. They have properties that enhance adhesion, filling in minor surface imperfections and ensuring better uniformity in paint application.

When dealing with problematic surfaces, such as glossy finishes, metals, or surfaces with old paint, using a primer that is specifically made for adhesion helps ensure that the subsequent layers of paint adhere properly and do not peel or flake off over time. High-quality adhesion primers often contain additives that promote better bond strength, making them ideal for difficult applications.

While the other options may have some relevance in different contexts, they do not directly address the specific need for improving adhesion on troublesome surfaces as effectively as using an appropriate primer. For example, while solvent-based paints can adhere well to some surfaces, they may struggle on smooth or glossy finishes without a suitable primer. Similarly, increasing the paint temperature or lowering humidity levels can influence drying times and the paint's flow, but they do not inherently improve adhesion on problematic surfaces.
