Blistering, or bubbles on the surface of paint, is caused by the paint failing to stick and separating from the surface it was applied to. Common causes include improper surface preparation, moisture infiltration, and poor ventilation. Moisture issues are one of the primary reasons for exterior paint bubbles, as they can result from heat, moisture, or a combination of both.
When the paint layer does not adhere perfectly to the underlying surface, such as the substrate, the new film of paint forms. This can be due to the surface having not been cleaned properly, leading to an uneven and unsightly appearance. To fix this issue, remove the bubbled paint and cleanse the area, smooth the surface with drywall mud if needed, and prime the surface with the right type for a perfect repaint.
Improper surface preparation can also contribute to the formation of paint blisters. Heat causes the moisture/air trapped beneath the film to expand and force its way out by forming blisters. Surface contamination can also be trapped beneath a new layer of paint.
Blisters or bubbles can develop when the layer of paint does not properly adhere to the surface. When the new layer of paint dries up, it will pull away from the underlying surface. One of the primary reasons for exterior paint bubbles is moisture infiltration, which can be prevented by poor ventilation.
In conclusion, the main causes of exterior paint bubbles are moisture infiltration, improper surface preparation, and poor ventilation. By addressing these issues, you can restore the beauty of your home and prevent future issues from occurring.

What causes paint to bubble when it rains?
The presence of excessive moisture can result in the formation of blisters in painted surfaces. This phenomenon can be observed in settings where high humidity levels are present, such as in bathrooms or laundry rooms. Additionally, the application of exterior paint over damp surfaces can also lead to the development of blisters. The formation of blisters may be observed during periods of precipitation or heavy dew formation.
Is it normal for paint to bubble?
Poor-quality paint often contains fillers and low-grade resins, leading to a lack of adhesion and causing paint to bubble and blister. This issue is common among homeowners and can be repaired by following proper thinning and dilution of paint. Proper thinning and dilution of paint are essential to prevent bubbles and poor coverage. When painting an alkyd/oil surface with latex paint, it is essential to follow the manufacturer’s recommendations for thinning and dilution.
If the bubbles are only on the surface, they don’t pose a real danger to your home. However, addressing the problem as soon as possible is crucial to prevent further damage. Proper thinning and dilution of paint are essential for a smooth and long-lasting finish.

How do you fix bubbling paint without repainting?
To remove bubbled paint from surface-level issues, start by scraping off the bubbled paint, sanding it down for primer, filling any holes and cracks with a patching compound, letting it dry overnight, and sanding again with a fine-grit sandpaper. Clean the area, apply a primer, and allow it to dry completely before repainting. Repainting the entire wall or a large section is recommended for a seamless finish, as old and new paint can be noticeable and matching issues may occur if the exact paint used was not used. Repainting the entire wall upfront saves time and headaches in the long run.
How do you prevent paint bubbles?
- Clean walls with a damp towel or sponge and warm water. Add soap to the warm water for extra cleaning power.
- Dry walls completely before starting to paint to avoid paint bubbles. Open windows and doors to increase airflow or run a dehumidifier and turn on fans to help dry out.
- Watch the weather and plan to paint on days that are not hot or humid to ensure even drying.
- Don’t rush and brush paint on the walls too fast, as this may introduce air. If painting by yourself, ensure each coat is dry before starting the next one.
- Match paint types, as latex and oil paint don’t mix well. Prime over old paint or use the same paint type that’s already there.
- Prime before painting to get the best, most even paint job. Be sure to know the ins and outs of primer before getting started.
- Avoid exterior paint blistering, especially on rainy or very hot days.

Does bubbling paint mean water damage?
Paint peeling, cracking, or bubbling is often caused by water, which can indicate roof problems, daily water use, or excessive humidity. Paint blisters or bubbles occur when the paint film lifts from the underlying surface. Common causes include leaks from plumbing fixtures or a leaky roof, which can cause blisters or bubbles on painted surfaces. Over time, moisture from these leaks damages the drywall behind the paint, leading to widespread sagging, blistering, or bubbling in ceilings or walls. Inside wall cavities may be cracked piping, a failed seal, or a loose connection. Remediation is necessary once water enters the area.
How do you fix bubbles in exterior paint?
Applying paint to a poorly prepared surface can cause adhesion issues and bubbles. Inadequate cleaning, sanding, or priming can prevent proper paint adhesion, leading to bubbles over time. To fix this, scrape off bubbled paint, clean the surface, sand it smooth, apply a primer, and repaint with high-quality exterior paint. Extreme heat and prolonged sun exposure can cause surface expansion and contraction, causing bubbles. Direct sunlight can also degrade paint’s protective properties, allowing moisture to penetrate and cause bubbles.
To avoid poor adhesion and bubbling, choose paint specifically formulated for exterior use and invest in high-quality paint products that offer excellent adhesion, durability, and resistance to moisture and UV rays.
What causes paint to bubble on exterior wood?
An exterior paint’s breathability refers to its ability to allow moisture to escape from the surface. Low breathability can cause moisture to build up, lifting the paint film and causing it to bubble. Most exterior paints today are acrylic-based, which have low breathability, leading them to fail after 1-3 years. A combination of high breathability and water repellent properties prevents paint from failing. If an exterior paint lacks these properties, moisture will cause it to fail, leading to peeling, bubbling, or cracking.
Poor preparation is another factor that can lead to paint failure. Poor preparation can occur in various forms, but 9 times out of 10 means that the surface was not properly cleaned before applying the paint. Masonry surfaces, in particular, can gather large amounts of dirt and organic growth, which can cause bubbling paint. Therefore, proper preparation is crucial for preventing paint failure.
Do paint bubbles go away?
Paint bubbling on walls is a common issue experienced by DIY painters after completing a paint job. It usually indicates that air or moisture has been trapped between the paint layers or between the paint and the wall surface. Air- or water-filled bubbles form where the paint pulls away, and some deflate or pop on their own during the drying process, while others harden in place. Paint bubbling can occur hours or months after the job, and oil-based or latex paint coats can be forced free at any time. To avoid paint bubbles, it is essential to identify the cause, do minor prep work, and use the right tools.
A common cause of paint bubbling is applying paint on a surface that hasn’t been adequately prepared, such as dirty, greasy, or old peeling paint. It is advisable to clean walls before painting to prevent dust, dirt, and grime from collecting on interior walls and ceilings over time, making fresh paint difficult to adhere to.
Is paint bad if it has bubbles?
Paint blistering and bubbling are common issues faced by homeowners, often only on the surface and not causing significant damage. To prevent further damage, it is crucial to use the appropriate thickness or dilution of paint, as excessive thinning can result in bubbles and poor coverage. To remove the damaged paint, use a sharp putty knife to scrape away the bubbled paint. Prepare the surface by sanding and cleaning it with a damp cloth. Apply a high-quality primer to ensure proper adhesion, using a thin layer of spackle in high visibility areas.
Sand and prime again before painting. Repaint the affected area by applying a thin layer of paint and allowing it to dry completely before adding additional coats. For the best result, paint the entire wall, corner-to-corner, as it is difficult to match existing paint. Following the manufacturer’s recommendations for thinning and dilution is essential for a successful paint job.
Why is my old paint bubbling under my new paint?
To prevent paint bubbles, it is essential to prepare the surface properly, make necessary repairs and clean well before painting, and ensure one coat is dry before adding additional coats. Use high-quality paint and a roller with a thick nap to ensure even application. Popular brands include Kelly-Moore, Sherwin-Williams, Benjamin Moore, PPG, Behr, Valspar, and Rust-Oleum.
Use multiple thin coats instead of one thick coat to trap air underneath the paint and prevent bubbling. Allow proper drying time for each coat, as not fully drying can cause air pockets to form and create a bubbled effect. Follow the instructions on the product label.
