Stopping the leak before repainting is crucial primarily to avoid the potential for mold growth. Water leaks can lead to moisture accumulation, which creates a conducive environment for mold and mildew to thrive. If a leak is not addressed, any paint applied over damp surfaces is likely to trap moisture underneath, ultimately leading to paint peeling, bubbling, or discoloration. Additionally, the presence of mold not only damages the underlying structure but can also pose health risks to occupants. By ensuring that the leak is resolved prior to repainting, you help create a dry, stable surface for the paint, which enhances longevity and protects the integrity of both the paint and the structure.

While addressing other factors like cost, adhesion, and aesthetics is worthwhile, those concerns become secondary if moisture is continuously present due to an unresolved leak.
