Wrinkling: A rough crinkled surface caused by a drying interference and forming a wrinkled skin.
Wrinkling probable causes: Applying the paint too thickly. Painting over an insufficiently cured primer. Painting during extreme hot or cool/damp conditions will cause a drying interference and the paint film will skin rather than curing properly.
Wrinkling solutions: The wrinkled layers must be totally removed by sanding/scraping. Stubborn underneath layers may require liquid paint remover. Bare areas need priming and allowed to dry. Spread uniformly and avoid painting in hot direct sunlight or when the temperature is below 50°F.
Primers & interior finishes: Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality interior paint in the color and sheen of your choice.
