Top 4 Things That Causes Paint Blisters and Bubbles and How To Prevent them

A fresh coat of paint can significantly enhance the beauty of your home. However, paint blisters and bubbles can quickly tarnish that beauty, creating an unsightly and damaged surface. This issue is more common than you might think, but the good news is that it’s preventable. In this article, we’ll help you understand what causes paint blisters and bubbles and how to prevent them from ruining your perfect finish.

Paint blisters or bubbles appear as small to large raised areas on the painted surface. They occur when the paint lifts from the underlying surface, creating a ‘bubble’ or ‘blister’ effect. These can occur shortly after the paint application or even months later.

Understanding what causes these blisters and bubbles is the first step to preventing them. Here are the common culprits:

Water is a major enemy of paint. When painted surfaces are exposed to excessive moisture—through high humidity, leaks, or condensation—the water can infiltrate the paint layer, causing it to separate from the surface and form blisters or bubbles.

Heat and direct sunlight can also cause paint blistering. When a surface gets excessively hot, the paint can dry too quickly, trapping solvent or moisture beneath the surface, which then forms blisters as it tries to escape.

If the surface isn’t properly prepared before painting, the paint might not adhere correctly, leading to blisters and bubbles. This includes not cleaning the surface adequately, failing to remove old, loose, or flaking paint, and not applying primer.

Using the wrong type of paint for a particular surface or environment can lead to paint blistering. For example, oil-based paint applied over latex paint can cause issues. Similarly, if the paint is applied too thickly or if it’s not properly brushed out, it may bubble or blister.

Now that we understand the causes let’s discuss the prevention strategies:

Surface preparation is paramount for a successful paint job. Ensure the surface is clean, dry, and free from loose or flaking old paint. Any cracks or holes should be filled and sanded smooth. A primer should be used for better paint adhesion.

Choose the right type of paint for your surface and environmental conditions. If you’re painting over old paint, make sure the new paint is compatible. When in doubt, seek professional advice.

Painting can involve working at heights, using ladders, and handling potentially harmful chemicals. If you’re unfamiliar with proper safety practices, there is a risk of accidents, injuries, or damage to your property. Professional painters are trained in safety protocols and have the equipment to work safely.

Resist the temptation to load up your brush or roller to get the job done faster. Apply paint in thin, even coats, allowing each coat to dry completely before adding the next one.

Before painting, fix any leaks and ensure the area has good ventilation to avoid high humidity. Consider using a moisture meter to check the moisture content of the surface before you begin painting.

Good-quality brushes and rollers help in the even application of paint, reducing the chances of blisters and bubbles.

Paint blisters and bubbles can be a frustrating issue for any homeowner or DIY painter, but understanding their causes and knowing how to prevent them can ensure your paint job remains smooth and beautiful. Remember, preparation is key, and taking the time to prepare your surface correctly will save you time and effort in the long run. If you find yourself in a situation where blisters or bubbles have already formed, it’s recommended to seek professional help to rectify the situation and avoid further damage to your walls.
