The short answer is yes, but success hinges entirely on understanding the nature of the existing finish and the preparation required. Applying thin, even coats is preferable to one thick layer, as it minimizes the risk of drips and ensures more uniform drying.
Choosing the Right Primer for Maximum Adhesion
Troubleshooting Common Issues Even with careful preparation, issues can arise if the environment or process is not managed correctly. This lack of adhesion is the primary reason for failure, making surface preparation the single most critical step in the entire process.
Light sanding with fine-grit sandpaper (220-grit or higher) is often sufficient for some products, but a more thorough approach involves using a deglossing liquid or a medium-grit sandpaper (120-150 grit) followed by a cleaning to remove all dust. Patience during the drying phase directly correlates with the final durability of the project.
Choosing the Right Primer for Ultimate Adhesion
A well-prepared surface is non-negotiable for long-term results. This very resilience is what makes painting over it a challenge.
