How to Fix Bubbled Paint in an Interior

Bubbled paint, also known as paint blistering, occurs for a variety of reasons, including improper surface preparation, wet surfaces or high heat and humidity during paint application. Painting a wet or damp wall interrupts adhesion and causes the paint to lift after the paint dries, leaving blisterlike patches on the wall. Applying paint to a wall when the temperature is high causes the paint to dry from the outside in and leaves paint bubbles on the surface.
