Professional residential painters are highly experienced when it comes to dealing with paint bubbles. Paint bubbles are usually caused by moisture in the substrate. When your walls get exposed to water, the water will want to evaporate. If the water is in the substrate which has no coating, then you are completely safe. It won’t be a problem to worry about. As the water evaporates and gets dry. If, on the other hand, the substrate is covered in coating, it will be difficult for water to evaporate. In the process, the water vapor pressurizes the coating to force it away from the substrate creating a bubble.
Causes of Paint Bubble
And yes, paint bubble has a solution. The best and most viable solution is to fix the root cause of the moisture problem. Moisture intrusion suspects include leaky windows, roof and gutter leaks and lack of proper flashing. Other possible causes of paint bubble include unsealed wood end grain, uncaulked vertical joints and seams around windows and doors, unprofessional construction works and many more.
In some cases, the moisture can move from the inside of a building, finding its way out through the exterior wall, resulting in paint bubbles. Possible culprit may include tub overflows, bad sinks or plumbing leaks.
If a building doesn’t have a vapor barrier, the vapor, in its quest to escape, will move through the exterior walls, causing paint bubbles. This is a possibility if you find paint bubbles on the outside of bathrooms, kitchens and laundry rooms. Improve ventilation and consider using dehumidifiers strategically.
Paint Bubbles in The Bedroom
Many homeowners wake up only to find paint bubbles on walls. This can be as surprising as there seems to be no obvious source of moisture. Here in lies your answer. In every 24 hours, the human body loses about 28 ounces of water. So how do all of this moisture escape?
Once the sun rises and the outside temperature rises, it is normal for moisture to evaporate. Some of the moisture are already in your exterior paint coating. As the temperature becomes hotter, the urge to evaporate increases, increase the likelihood of bubbling.
Fixing Paint Bubbling Problem
The best way to get rid of paint bubble is to opt for lighter paint colors. Light paint colors allows for more reflection of sunlight energy. The darker the color, the more sunlight energy is absorbed by the surface and the hotter it gets.
This is why professional residential painters recommend using light paint color for exterior walls to prevent paint bubbling problems. In addition, this further extends the lifespan of a paint job.
Paint substrate must be capable of not holding moisture back. It is thus important to get proper venting
Normally, paint coating is generally breathable. It is easy for moisture to evaporate without stress. However, the problem arises when you had the walls repainted over and over again. This will impact the breathability of the paint coating, allowing it to trap moisture.
