What can be a consequence of painting in high humidity conditions?

Painting in high humidity conditions can lead to poor drying and potential for blistering because the moisture in the air affects the evaporation of solvents in the paint. High humidity interferes with the paint's ability to dry properly. When the paint doesn't dry as expected, trapped moisture can cause the paint film to form blisters. These blisters are weak spots in the finish where the paint has lost adhesion to the substrate, potentially leading to further damage over time. Proper drying conditions are crucial to ensure a durable and high-quality finish, making it essential to monitor humidity levels before proceeding with a paint job.
