No, generally you should not paint over wet paint.
Painting over wet paint is almost always a bad idea and will likely result in a poor finish. Applying a new coat of paint before the previous one has fully dried can lead to a host of problems, both cosmetic and structural to the paint job.
Why You Shouldn't Paint Over Wet Paint:
- Bubbling and Blistering: Moisture trapped between the layers of paint can create unsightly bubbles and blisters.
- Cracking: As the wet paint underneath dries, it can cause the top layer to crack.
- Streaks and Clumps: Wet paint makes it difficult to achieve an even application, leading to streaks and clumps.
- Poor Adhesion: The top layer of paint may not properly adhere to the wet paint underneath, increasing the likelihood of peeling.
- Prolonged Drying Time: Applying more wet paint slows down the entire drying process.
What to Do Instead:
- Be Patient: Allow the paint to dry completely. Check the paint can for recommended drying times, as these can vary based on humidity and temperature.
- Assess the Finish: Once dry, inspect the paint for any imperfections.
- Prepare the Surface (If Needed): If imperfections exist, lightly sand the surface before applying another coat of paint.
- Apply a Thin, Even Coat: Apply the next coat of paint in thin, even layers, allowing each coat to dry thoroughly before applying the next.
In summary, avoid painting over wet paint to achieve a professional, long-lasting finish. Waiting for the paint to dry is a crucial step to avoid potential issues.
