Bubbling of the paint coating on home exteriors is a very common issue noticed in many homes. One of the primary causes for paint bubbles is the moisture found in the substrate whether it is wood, or stucco. Unlike heat blisters, moisture bubbles go through all the different coats of paint till down to the substrate.
During normal conditions, water will seek to evaporate from the surface. When the substrate does not have any coating, there is no problem for this to happen. Water will just escape from the substrate and evaporate. If there is any paint coat on the substrate with moisture, the water that is trying to evaporate will put enough pressure on the coats of paint and if it cannot penetrate, it will force its way to escape from the substrate leading to a bubble.
Stopping of moisture bubbles include finding and eliminating the source from which the moisture intrudes.
In leak detection, leaking windows, and leaks in roof and gutter are the usual suspects. Poor construction techniques, wood end grain left unsealed, seams and vertical joints around the doors and windows which can let rain water enter the substrate can all lead to bubbling in paint job.
Sink and tub overflows, plumbing leaks and moisture trapped inside a wall trying to escape from inside the home to the exterior paint can all be the possible culprits in bubbles in painting.
Paint bubbles outside the home can perplex both the homeowners and professional painters. This is because in some cases, there can be no visible source of moisture. This can also happen due to the moisture buildup in home interiors trying to evaporate through the walls during extremely hot temperatures.
