Nothing can top the sense of accomplishment you have after you paint your room yourself. However, that success you feel can immediately be gone as soon as you observe multiple blistering bubbles that appear all over your newly painted walls. Sure, you did your best to choose the best paints available, applying two coats, and setting them to dry. But where did it all go wrong? In this article, you’ll be able to understand more the reasons why paint bubbles, how to detect the issues of your interior paint, and why it’s best to leave it to the best painters near me.  



What Is Paint Bubbling? 

Paint blistering or bubbling happens once the paint loosens from the surface that it’s painted on, which leaves wall bumps. Such a bubble can be packed with fluid and usually causes the paint to crack. While this issue can be frustrating, it’s quite simple to fix cracked paint, particularly if you know why it happens.  

Common Reasons Why Paint Bubbles 

Primer is needed 

The key to making the paint adhere is to make the wall quite a bit uneven and rough. Yes, you can sand the whole wall. However, that’ll take you a long time to finish it. Rather, this is the time when it’s best if you apply a coat of primer to the surface, to help the paint stick.  

Roller Cover 

Once the coverage of paint across the wall is uneven, it makes areas where bubbles can form. One of the reasons why the coverage becomes uneven is utilizing a roller cover that’s not appropriate for the type of wall. As a basic rule, you need to utilize thin covers for smoother surfaces and thicker roll covers for rough areas such as brickwork, popcorn walls, stucco.  


Most likely, the paint will have a hard time adhering if the surface is moist. However, moisture can still result in paint blistering, even after drying the paint. For example, when your house gets flooded, the moisture can make the affected rooms’ paints bubble. Even walls beside or in rooms that are moisture-heavy, such as kitchens and bathrooms may experience bubbling.  

Surface preparation 

Because paint bubbling relates to the ability of the paint to stick to a surface, it’s only reasonable to think that the surface itself plays a major role in why this issue takes place. If you paint on surfaces that are moist, grimy, or dusty, you can expect that it will cause some paint blistering. You can also get the same results if you paint on top unprimed walls, or surfaces with a cracked and old layer of paint.  

Too much heat 

A lot of professional painters will suggest that you need to paint on warm days—and because of a good reason. Heat usually helps in drying the paint more efficiently. But when the surface you are painting is exposed to too much heat, it can cause the paint to unevenly dry. That’s particularly true when some portions of the wall are hotter compared to the others, like in sun-heavy rooms, near heaters, or next to ovens.
