If you’ve ever applied paint primer to a surface and noticed it turning yellow, you’re not alone. This common problem can be frustrating and can ruin the overall look of your paint job. But what causes paint primer to turn yellow, and what can you do to prevent it?

Causes of Yellowing Paint Primer

There are several factors that can contribute to yellowing paint primer. Some of the most common causes include:

• Poor-quality primer: Not all primers are created equal. Some primers are made with low-quality ingredients that are more likely to yellow over time.
• Improperly mixed primer: If the primer is not mixed properly, it can cause the ingredients to separate, which can lead to yellowing.
• Exposure to UV light: UV light from the sun can cause the pigments in the primer to break down, resulting in yellowing.
• High humidity: High humidity can also cause the primer to yellow.
• Contamination: If the primer is contaminated with dirt, grease, or other substances, it can cause the primer to yellow.
• Improper application: If the primer is applied too thickly or not allowed to dry properly, it can also cause the primer to yellow.

How to Prevent Paint Primer from Turning Yellow
