7 Common Paint Problems (Solved!)

Paint issues can crop up even with careful preparation and application. Understanding what causes these problems and knowing how to fix them can save you time and effort. Here’s a rundown of seven common paint problems and how to solve them.

1. Peeling Paint

Cause: Peeling usually happens when paint isn’t properly adhered to the surface. This may result from moisture seeping into the wall, painting over dirty or glossy surfaces, or using low-quality paint.

Solution:

• Remove peeling paint by scraping and sanding the area.
• Ensure the surface is clean, dry, and primed if needed.
• Use a high-quality, moisture-resistant paint for best results.

2. Blistering or Bubbling

Cause: Blistering or bubbling occurs when the paint lifts from the underlying surface. This is often due to moisture, painting over a wet or damp surface, or exposing freshly painted surfaces to high humidity.

Solution:

• Sand the affected area, then clean and dry it thoroughly.
• Apply a primer to prevent moisture from penetrating.
• Paint when humidity is low and avoid painting in direct sunlight or high temperatures.

3. Cracking and Flaking

Cause: Cracks appear when paint becomes brittle with age or when too many coats are applied, causing the paint to split or flake.

Solution:

• Scrape away the cracked paint, sand, and smooth the surface.
• Apply a primer if needed, then repaint using thin, even coats.
• Opt for flexible, high-quality paint that can withstand minor surface movements.

4. Mildew Growth

Cause: Mildew is common in areas with high humidity or poor ventilation, such as bathrooms and kitchens. It shows up as gray or black spots and can ruin the paint.

Solution:

• Clean the area with a mixture of water and bleach (1:3 ratio) to kill mildew spores.
• Rinse and dry completely before painting.
• Use mildew-resistant paint, especially in moisture-prone areas, and improve ventilation in these spaces.

5. Staining and Discoloration

Cause: Stains may appear due to water leaks, smoke, or other contaminants bleeding through the paint.

Solution:

• Identify and resolve the cause of staining, like repairing leaks or sealing smoke stains.
• Apply a stain-blocking primer before repainting to seal any marks or discoloration.
• Use high-quality paint that resists stains.

6. Chalking

Cause: Chalking happens when paint forms a white, powdery residue on the surface. It often occurs with outdoor paint exposed to UV light or when low-quality, powdery paint is used.

Solution:

• Wash the surface to remove chalking residue.
• Repaint with a durable, UV-resistant exterior paint.
• Regularly clean and maintain exterior painted surfaces to prevent excessive chalking.

7. Paint Runs and Sags

Cause: Paint runs when it’s applied too thickly or in conditions that don’t allow it to dry properly, like humid or cold weather.

Solution:

• Sand down any dried paint runs, then reapply thin, even layers of paint.
• Avoid overloading your brush or roller, and paint in manageable sections.
• Allow sufficient drying time between coats and ensure proper temperature and humidity.
