One of the more annoying things that can happen to your paint after you apply it, is that it starts to bubble. We’re going to show you why this happens and how you can handle it to ensure that it doesn’t detract from the beauty of your paint job.
Why Does Paint Bubble?
If your interior house paint starts to bubble, then that usually means that there is some moisture underneath the surface or on the surface. This moisture can find its way through all the layers of paint you apply.
This moisture can come from any number of places, but until you deal with that water problem, the paint will continue to bubble. It has nothing to do with the quality of the paint or the paint job and everything to do with environmental factors. Experienced painters can deal with this problem just as often as homeowners doing the work themselves can.
Stop the Moisture
You have to locate the source of the moisture problem. It could be a leaking pipe, bad insulation, water that has seeped in somehow or storm damage. Your wood or other surface could just be old and in need of replacement, which could explain why it has absorbed so much moisture. If it is falling apart, then it may be overly wet as well.
In many cases, you can simply remove the water source. Fix the broken pipe, dry up the excess water, repair a leak or close off a hole to the outside. Any of these may be enough to stop the water from damaging your surface, and afterwards you just need to give surface time to dry out. You can speed up the process by setting up fans or providing ventilation for the area to be painted.
If it is your home’s exterior that has a water problem, then you may just need to wait until the warmer weather has dried up your surface to be painted. It may be necessary to replace some materials that are too old or that have absorbed too much water. If you aren’t sure if you can still use some damaged material, then consult with a panting contractor to find out.
In order to keep bubbles from forming in places where you already painted, you need to ensure that the surface can breathe easily. This means that air needs to be able to come in and out. Most paint is designed to be breathable. However, if you use the wrong kind of paint or don’t do a very good job of applying it, then the surface can trap in moisture and release it as paint bubbles.
If there is a layer of paint on the surface to be painted that it is preventing breathability, then it may need to be removed. It is sometimes necessary to strip away old paint to make room for the new paint. This not only makes the surface more breathable and eliminates paint bubbles, but it also ensures that the new layer of paint can hold on better and longer.
