What condition causes paint to wrinkle?

Explanation:
Wrinkles form when the paint film is too thick. When you lay down a coat that’s too heavy, the surface dries and sets while the inner portion is still wet. As the underlying material continues to lose solvents and shrink, the top layer can’t contract evenly, causing the film to crinkle into wrinkles. To prevent this, apply thin, even coats and let each coat dry thoroughly before adding another, keeping temperature and humidity in check.
