Blistering is a common issue that can ruin the aesthetics of your home’s exterior. It can be caused by several factors, including damp surfaces, dirty surfaces, chemical reactions, wrong paint, and poor drying conditions. Paint blistering occurs when the top layer of paint fails to stick and separates from the surface it was applied to.
Measure is one of the primary culprits behind bubbling paint. When water seeps through cracks, gaps, or poorly sealed surfaces, it can get trapped between the paint layer and the substrate, causing bubbles. To fix this issue, first identify the cause of the paint bubbles and address the problem.
There are several reasons why exterior paint can bubble: painting in direct sunlight or on a damp, wet surface; applying oil-based or alkyd paint over a damp or wet surface; and exposing a surface to moisture. Moisture issues, improper surface preparation, and excessive heat and sun exposure are some of the main causes.
When the painted surface is heated by the sun, the moisture/air expands and blisters form because it cannot escape freely. This is often quite severe on the painted surface. If the siding had been not allowed to dry, the paint coating that was applied was not fully bonded to the coat beneath it.
Blisters or bubbles appear when a layer of paint does not adhere perfectly to its underlying surface, known as the substrate. As the new film of paint forms, pockets of air or moisture expand and contract with the surface.
To fix exterior paint blistering, follow these steps:
- Clean the surface thoroughly.
- Apply a new coat of paint to the affected area.
- Allow the paint to dry completely before applying the next coat.
- Clean the surrounding area thoroughly.
- Apply a second coat of paint if necessary.
- Clean the area thoroughly after applying the last coat of paint.
In summary, exterior paint blistering is a common issue that can be resolved by addressing the root causes of the issue.

Why is my exterior paint blistering?
Paint blisters or bubbles occur when the paint film lifts from the underlying surface due to heat, moisture, or a combination of both. This condition can lead to peeling and can be corrected by addressing the underlying cause. Causes include painting on damp, dirty, or hot surfaces, applying oil-based or alkyd paint over latex paint, improper surface preparation, excessive moisture, and exposure to latex paint shortly after drying.
To prevent paint from bubbles, ensure the surface is clean and dry, apply primer-sealer over stains, prime new joint compound with latex primer, avoid painting in hot or humid conditions, let paint dry completely before exposing the surface to moisture, and consider installing vents or exhaust fans in humid areas.
Does bubbling paint mean a leak?
The presence of bubbling paint on a wall may be indicative of a water leak. In such an instance, the most effective course of action would be to pop the bubble in order to facilitate drainage and drying. Nevertheless, if the water source is uncontaminated, the problem may be a roof leak, which can cause considerable damage if not addressed promptly.
What is the most common cause for paint blistering?
Blistering is a common issue in vehicle repair and painting due to the saturation of the film by high atmospheric humidity and the presence of water-soluble materials, such as primer. These materials can deform the paint film and weaken adhesion between coats or between the paint process and the metal. Micro-blistering often occurs when vehicles are repaired or painted under adverse conditions. To minimize the risk of blistering, ensure the paint area is clean and dry, use the correct thinner with each coat of paint, and avoid using cheap quality thinners with high moisture content.
Apply sufficient primer and topcoat in even coats, ensuring a sufficient primer film is left after sanding and a similar film weight of topcoat. Low film build can weaken the paint structure and lead to blistering, especially in spot or localized repairs.
During the painting process, ensure the surface is clean, free of grease, and dry. Adhere strictly to flash off and drying times set by paint manufacturers. Rushing jobs may seem like saving time, but in the long run, the vehicle may need further rectification.
Can you paint over blistered paint?
To remedy the formation of paint bubbles, it is necessary to remove the blisters by scraping and sanding. Once this has been done, the area should be coated with primer before the application of a quality acrylic latex interior paint. In the event that the blisters extend to the substrate, it is necessary to eliminate the moisture source, repair the loose caulking, and consider installing vents or exhaust fans to reduce the humidity within the dwelling.
How do you stop damp bubbling paint?
To prevent paint from bubbles, ensure the surface is clean and dry, apply primer-sealer over stains, and prime new joint compound with latex primer. Avoid painting in hot or humid conditions and let paint dry completely before exposing it to moisture. Paint blisters or bubbles can form when the paint film lifts from the underlying surface, caused by heat, moisture, or a combination of both. The underlying cause must be addressed to prevent recurrence.
Causes of paint bubbles include painting a damp, dirty, or hot surface, applying oil-based or alkyd paint over latex paint, improper surface preparation, excessive moisture, and exposing latex paint to moisture shortly after it has dried.
How long does it take for paint to blister?
The formation of temperature blisters is typically observed within a few hours or days after painting. These blisters are caused by the pressure exerted by the transition from liquid thinners in fresh paint to vapors. In contrast, glossy-back blisters occur between layers of old paint.
Why are bubbles appearing when I paint?
The most common cause of bubbling paint is excessive moisture exposure, which can result in a loss of adhesion between paint layers. This can be caused by humidity, poorly constructed drywall, leaks, or external wall cracks. It is crucial to address these issues before starting the painting process. It is also essential to paint when the temperature is between 50 and 85 degrees Fahrenheit, as temperatures over 85 degrees Fahrenheit can cause uneven drying. Additionally, improper cleaning of the walls, especially if grease and dirt are present, can also contribute to bubbling paint.
What temperature does paint blister at?
To avoid premature paint failure and wasted time and money, it is crucial to know the temperature range for successful painting or staining of your home or shed. Painting at temperatures over 90°F can cause bubbles and blisters, and it is generally not recommended to apply paint when the temperature is below 35°F. Additionally, paints react to temperature and humidity changes, and excessive moisture in the air can cause the paint to not cure properly. It is essential to avoid repainting your house due to these conditions, as it can lead to premature paint peeling and a waste of time and money.
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.
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.
