Has your paint started to bubble or blister on the walls? It’s an annoying issue that can ruin your newly painted space. But don’t worry — you’re not alone. In this guide, we’ll explain what causes paint bubbling on walls and how to fix it effectively.
What Is Paint Bubbling on Walls?
Paint bubbling on walls takes place when moisture or air gets stucked beneath the paint’s surface. This results in blisters or visible bubbles, which can tarnish from the finish and quality of your painted space. While this can happen to anyone, understanding the causes of bubbling of paint can help prevent it from happening again.
Common Causes of Bubbling of Paint on Walls
- High humidity
Excess moisture in the wall or the paint itself is one of the leading causes of bubbles on paint. If the walls aren’t well-primed or sealed, moisture can get in and make the paint bubble. Have you noticed your paint bubbling more in humid areas like your bathroom? That could be why!
Tip: Always ensure walls are dry before painting. Humidity can ruin your finish before it even starts.
2. Poor Surface Preparation
Not preparing the surface properly could lead to bubbling of paint on walls. Any dirt, dust, or grease left on the surface can cause the paint to fail to adhere properly. Don’t skip the prep! It’s key to getting a smooth, long-lasting finish.
Tip: Clean walls thoroughly before applying any paint. Need help prepping your home? Check our tips on preparing your home for painting.
