What Is Paint Peeling and Blistering?
Paint peeling is closely related to paint bubbling and blistering, which occur when paint starts lifting from the surface and forms large bubbles in the finish.
Paint bubbling and blistering are the same thing, so the terms can be used interchangeably — both describe paint that has lost adhesion to the underlying surface.
Common Causes of Paint Peeling
The most common culprits behind paint peeling and bubbling are surface contamination, improper cleaning, environmental factors, and incompatible additives.
Painting over surfaces contaminated with oil, wax, grease, or silicone is a leading cause of poor paint adhesion and eventual peeling. Proper surface prep — including thorough cleaning — is essential before any paint project begins.
Lead Paint Concerns in Older Homes
In 1978, the federal government banned the sale of lead-based paint for use in homes, childcare facilities, and preschools. Approximately three-quarters of homes in the United States built before 1978 still contain some lead-based paint.
When painted surfaces are not maintained and paint deteriorates, peels, chips, or cracks, it can become a hazard — especially for children. Old or worn lead-based paint on surfaces subject to constant friction, like doors or window sills, can produce chips and dust that become hazardous when inhaled or ingested.
Fixing Peeling Paint and Planning Your Next Project
Knowing the causes of paint peeling — such as surface contamination or environmental exposure — is the first step toward preventing the problem on future projects. Addressing the root cause before repainting helps ensure a flawless, long-lasting finish.

Key takeaways
- Paint peeling, bubbling, and blistering all describe the same problem: paint lifting from a surface, often caused by contamination, moisture, or poor surface prep.
- Peeling paint in pre-1978 homes may contain lead — a health hazard, especially for children, when paint chips and dust are inhaled or ingested.
