Paint Bubbling - Causes & Solutions


Paint Bubbling Paint Problem 

Paint bubbling is a common occurrence that can happen when you least expect it. Whether you use oil or water-based paints, bubbling paint can mysteriously appear because both types of paint are equally susceptible. Knowing the most common causes before you begin can greatly reduce the chance of this happening.
 

Conditions that cause paint to bubble

Several factors cause paint to bubble. In walls that were just painted, a nearby heat source, humidity or an incompatibility with the surface of the underlying wall, are all potential culprits. Where there is too much heat or humidity the layers that make up the paint harden and separate from each other. This leaves a filmy space in between where air gets trapped and forms small bubbles. Not cleaning the surface before it is painted can also cause new paint to dry unevenly. All of these conditions can cause bubbling.
 

What you can do to eliminate paint bubbles

Prior to painting there are steps you can take to lower the chances of having bubbles form in your paint. The best way to avoid bubbling is to make sure that your underlying surface is completely free of debris. Avoid using porous materials as your foundation. Primer helps paint adhere to the surface. Make sure to use primer that is compatible with your paint. Do not use oil-based primer with latex paint, or vice versa. In the event that bubbling occurs, carefully sand the bubble out, apply another light coat of paint, lightly sand the area again and then apply a second coat over the area, making sure to feather the paint into the existing edges. These methods effectively reduce or eliminate bubbling.

It is always better to start with a clean surface before you paint. This saves you time and headaches doing repair work later. Remember, the better prepared you are before applying paint, the better the results are in the end.
