Blisters share the same appearance with skin blisters or what we commonly call as paltos. You might have suffered from blistering before, so I bet you already have a clear vision of what it looks like.

Not that visually-pleasing, right? The same thing can happen on your wall. Common Painting Problems: What is Blistering?

Paint blisters are those slightly lifted paint film on your wall that result from the detachment of the paint from the surface beneath. The most common cause is moisture entrapment. There might be something wrong with the surface preparation or there’s a problem with the waterway that causes leaks. Whichever it is, the tendency is, when the heat from the sun directly hits the surface, the water turns to vapor and pushes the paint upwards but it won’t go through so it stays and creates bulges on your wall. That’s blistering!

If not treated right away, blistering might even lead to further paint problems including flaking and peeling of the paint. In either case, you can always consult a professional for guidance.

One thing you should also know about blisters is it usually form on paints with sufficient sheen or gloss. Flat finish seldom blisters. This is because paints with more gloss tend to flex with pressure which is hardly ever the case for flat finishes. But, you still need to be cautious, you might get away with the blisters but remember that as water successfully escapes the film, it will leave salt deposits which form efflorescence on your wall. 

Preventive Measures to Avoid Paint Blisters

But you don’t need to worry your pretty little head over it, saving your wall from these impending disasters will only take these simple preventive measures:

1.  Clean the surface

I cannot overemphasize enough the importance of proper surface preparation. Do yourself a favor and spare a few minutes of your time cleaning and examining your wall for potential problems before every paint job. Eliminate dirt particles, fill holes and repair cracks.

2.  Don’t skip the primer

Oops! You did it again. You skipped the primer… again, in pursuit of cutting down the cost. Wrong. It will only cost you more in the long run due to repairs and renovations. 

Painting is a system. To ensure the best result, especially if you’re doing the painting all by yourself, you must strictly follow the right procedures and that includes proper surface preparation (as explained above) and applying primer before the top coat. Aside from acting as a sealer that protects the surface from unwanted particles, a primer also ensures better adhesion of the top coat. 

Note: After cleaning and preparing the surface, let it dry completely before applying primer.

The Key is Finding the Source of the Pressure

Say blisters already found their way to your precious wall, now you need a game plan. Here’s what you need to do: 

In order to completely eliminate the blisters, you have to find the root of the problem. Once you scraped all the blisters off the wall, you need to locate and address the source of the moisture and pressure that keeps pushing the paint from behind or it’s just going to repeat the same cycle again and again.

There are two things to remember when it comes to water, if it goes through, it has to come out. And when it decides to come out, it always chooses the path of least resistance. Which is why in some cases, blisters form away from the source. This is the tricky part. The loss of adhesion underneath the paint might have formed a trail for water to flow right in. If you find yourself in this situation, you have to check every possible entrance of water around the surface. Check pipes and gutters for possible clogs and leaks.

If the complication goes beyond your capability, it’s time to call a professional for assistance to prevent further damage. Don’t be afraid to ask for help. The most important thing is to save your wall that you worked hard for. Who knows you might even learn a thing or two about taking care of your wall!
