Why is my newly applied interior paint peeling off in sheets?

# Why Interior Paint is Peeling

Peeling in sheets usually means one of these issues:

Poor Surface Prep — This is the #1 cause. If the wall wasn't cleaned, sanded, or primed properly, new paint has nothing to grip. Old paint, dust, or glossy finishes prevent adhesion.

Moisture Problems — Water behind the walls (from leaks, humidity, or poor ventilation) causes paint to bubble and peel. Bathrooms and kitchens are especially vulnerable.

Wrong Paint Type — Using flat paint in a high-moisture area or applying paint over a shiny surface without primer leads to failure.

Incompatible Products — Mixing oil and latex paint, or using poor-quality paint, can cause adhesion failure.

## What to Do Now

Stop the peeling from spreading by scraping off all loose paint down to solid adhesion. Then: - Find and fix any moisture sources - Sand the area smooth - Prime with a quality primer (especially important!) - Repaint with appropriate paint for that room

If the peeling is extensive or you suspect moisture damage, a professional painter can diagnose the root cause and fix it properly.

Tip: When hiring a painter to fix this, ask about their surface prep process—it's where quality work begins. Good painters should guarantee their work and use primer on bare surfaces every time.
