Humidity Forms Mold Growth
Each material that has mold must be washed with chlorine before painting, left in place for 1 hour, and then wash it with a damp cloth. Before applying new layer of paint, it is necessary to dry completely.
Unless you solve the humidity source, you will continue to get eruptions and mold , even with fresh paint.
Is It Safe To Pop The Bubble In Your Wall
Generally, it is not recommended to pop the bubble on your wall. Chances are, the bubble itself is slightly damp, and may have taken on a tissue-like texture, so you wont even be able to pop it.
To get rid of bubbles safely, remove the paint in the affected area but no more of the surrounding paint, rub the area beneath with sandpaper to make sure its smooth, and apply joint compound to repair the wall.
Make sure the area gets cleaned, then use a peel-stop or sealer binder when repairing, sand the surface, and apply primer before you repaint.
Water Bubble In Wall Should You Pop It How To Fix It Easily
An unfortunate reality of painting a wall is that it can go wrong pretty easily. Even if youve done everything correctly, sometimes a water bubble in your wall will appear, causing panic and frustration over what you can do to correct it.
Water bubbles between the wall face and the paint should be popped with great care. Afterwards, it is important to determine the source of the water to prevent any future leaks. In some instances, a professional is required.
Its important to note that this issue is three-fold. You will need to identify and repair the source of the water leak, repair your damaged wall, and inspect surrounding areas for other signs of damage.

What Causes Water Damage On Walls And Ceilings
There are several possible causes of water damage on walls and ceilings. Leaking pipes, overflowing sinks or bathtubs, and heavy rains can all lead to water damage in your home. Even a small water leak that may not seem like a big deal can impact your homes structure if left unchecked.
Water damage can also be caused by excess moisture. Condensation, for example, from high humidity or steam from cooking or bathing, leads to an increase in moisture. In some cases, water damage may be the result of a faulty appliance, such as a dishwasher or washing machine.If you are seeing water spots on your walls or ceilings, it is likely that the drywall has been saturated with water. Once the drywall is saturated, it can quickly deteriorate and may even need to be replaced.
Water damage can also cause wood rot in your walls and ceilings, which can lead to structural damage and may require extensive repairs.
Discoloration Of The Walls Or Ceiling
Water damage usually shows up as discolored drywall. Staining patterns showing through the wall can show up as circular stains or streaks running down the wall from the ceiling. These streaks can be short, a few inches long, or long, running all the way down.
Oftentimes, discoloration is coupled with softened drywall, so look for soft spots where the drywall is discolored.

Apply A Second Coat Of Joint Compound
When the mud is dry, remove any ridges using the joint knife to shave them off with upward strokes of the blade. Also, lightly sand the whole patch if necessary to smooth out any other bumps or protrusions before applying another coat. At the edges of the patch, sand to feather the mud with the surrounding surface.
Wipe the sanding dust off with a damp rag and apply a second coat of mud, skimming perpendicular to the first coat. If you skimmed the first coat vertically, apply the next with horizontal strokes. This will help to level out the surface.
Let the second mud coat dry and if necessary, apply another to build up the patch until it hides the damage and smoothes out the surface. As before, skim the mud stroking perpendicular to the previous coat.
Using Putty In Areas Near Water
Putty prevents the swelling up of water bubble from inside . Eventually it gets flashed and ends up falling apart because it absorbs so much water. The water evaporates and forces the paint to push upwards, creating bubbles.
In most cases, paint bubbling appears on new painted walls due to the issue of humidity. Painting cannot be carried out until the humidity issues are resolved. In few cases plaster may be require to be redone.

How Does It Occur
When the painted surface is subjected to excessive amounts of moisture it causes the paint film to swell it occur and eventually lose its adhesion to the substrate. This may appear worse during wet weather periods as the blisters fill with water. Blistering of the paint film due to swelling is most likely to occur within the first few days in the life of the completed project.
The coating systems ability to breathe and to allow moisture to pass slowly through the dry paint film is a characteristic called Water Vapour Transmission. However, even the most effective coatings formulated to the highest quality can only withstand a certain amount of hydrostatic pressure before blisters start to form. In simple terms the coating cant breathe fast enough to let the moisture out quickly.
A typical example of the damaging effects of hydrostatic pressure on a paint coating can be observed on a masonry retaining wall which has NOT had an effective waterproofing system applied.
The moisture from the soil and garden beds behind the retaining wall will pass through the wall and attempt to escape through the paint coating on the exposed surface.
If the hydrostatic pressure is too high then the moisture will be unable to escape effectively or quickly enough resulting in the formation of blisters.
Other typical examples of where increased levels of hydrostatic pressure cause problems include…

Should You Sand Back And Paint Over Paint Bubbling On A Wall
NO. No, no, no, no do not just sand back the paint that is bubbling and paint over it again. All you are doing is putting fresh paint on the surface that will start to bubble again in the near future. You are avoiding repairing the cause of the paint bubbling and this doesnt make any sense because even more damage could be getting created that you cant see.
If you are in a second storey there could even be water leaking into the roof or walls downstairs.
If you live in a house with timber floorboards and beams these could be starting to rot or mould could be building up in the home which is not ideal if you have children.

What Causes Bubbling Or Blistering Paint
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 dries and pulls away, pockets of air or water form underneath. Some of these deflate or pop on their own, making the uneven surface less noticeable though the blistered areas may never fully reattach to the substrate and later begin to peel. Other bubbles or blisters harden in place as the paint dries, resulting in a blemished surface that youll need to fix.
The most common factors that prevent paint from fully adhering are dirt, moisture, extreme heat and an inadequately prepared surface.
For interior and exterior painting projects, the most common and biggest mistake I see is lack of preparation, says Rick Watson, director of product information and technical services at Sherwin-Williams. Most people just want to start painting, but everything needs to be washed and cleaned first. Even before you start taping off areas, you must always make sure the area to be painted is clean, dry, dull and sound.

Leakage Moisture Or Mold In The Surface
- Mostly, the bubbles under the paint material are water bubbles that expand outward. When you apply paint without checking for moisture-related issues, this thing happens.
- If you notice small bubbles appearing on the surface, call professionals and get an inspection done immediately. The professionals can detect the presence of molds or other issues before it spreads more.
- Plumbing issues, a burst pipe, or high humidity levels can result in water bubbles on wall. If this is the issue, you need to remove the paint completely and then treat the wall. Apply fresh paint to the wall only after completing the treatment.
Signs Of A Hidden Water Leak

Water can be life-giving and helpful in a home, but when unwanted water infiltrates a structure, it can turn dark and destructive. Water is insidious and sneaky and will creep into every crack and crevice in a home going unnoticed and causing continual problems for long periods. Hidden water damage within your walls can lead to serious damage that may require massive repairs. With this hidden danger, its important to know the warning signs of a moisture problem in your home so you can have it repaired before it gets out of control.
Musty Odors
When water absorbs into porous building materials like wood and insulation, musty odors are sure to follow. Mold and mildew grow quickly in the presence of moisture, leaving behind a musty and earthy smell that grows stronger as the mold continues to grow and spread. If you find that youre noticing a sudden mildewy smell, its a good indication theres a hidden water leak somewhere nearby.
Stains and Discoloration
Mold will not be the only visible sign of a water leak. When water absorbs into drywall and sheetrock, it causes discoloration and staining. Spots on the ceiling in walls that range from yellow to brown are an indication of a water leak within the ceiling or wall. Especially if the spots are changing colors or growing in size, theyre probably caused by a hidden leak that needs to be repaired before it causes more damage.

How To Fix Paint Bubbling/blistering
There are three steps to repair bubbled or blistered paint: removing the damaged paint, preparing the surface for a new coat, and repainting the entire surface or the affected area. First, however, you need to eliminate the underlying causes to avoid another bubbled paint job the second time around.
A coating is only as good as the surface it will be applied to, warns Watson. In fact, about 80 percent of coating failures happen because of improper preparation.
Sponge off surfaces with soapy water and dry thoroughly with a rag. Use a suitable primer to cover stains or prepare porous substrates like new drywall or plaster. And ensure that the ambient temperature is between 50 and 85 degrees F, or the range recommended by the paint manufacturer.
Bubbling caused by moisture can take some sleuthing to resolve. You may have a plumbing leak or water infiltration that needs to be addressed, or simply excess humidity in rooms like the kitchen, bathroom or basement.
You can keep humidity in check with a dehumidifier or fan while the paint dries. If water-filled bubbles appear on a painted exterior surface, Mundwiller suggests waiting it out a bit. Bubbling and blistering can be caused by rain if the paint hasnt had enough time to dry before a storm moves in, but in many cases once the sun comes out the bubbles disappear, he says.
Also, keep in mind that if youre preparing a surface that is covered in old paint, you need to take the proper precautions.
Wall Bubbling Versus Blistering Paint
Blistering paint occurs when the top coat of paint fails to adhere to the surface beneath. The surface could be plaster, but it could also be the primer. If you didn’t prime the wall, it could be your new and underlying paints were different typesoil and water bases do not work together. Other non-structural reasons for blistering paint include painting over a greasy surface or painting when the conditions were too humid. Painting in direct sunlight can cause the topcoat to dry too quickly, forcing the paint underneath to bubble up. Painting with the wrong roller or stirring your paint too rapidly can introduce air bubbles that remain once the paint dries. The main takeaway from blistering paint is that the problem is at the surface, not in the underlying structure.
On the other hand, internal wall bubbling points to water penetration and is a genuine problem for owners of historic homes – especially brick homes. Unlike surface-level paint blistering, bubbling plaster is almost always a result of damp conditions, and to repair the surface, you must first locate and correct the source of the problem. Remember, the bubbling plaster may first appear like blistering paint. If blistering paint is your only sign, it is important to get down to the plaster and ensure the problem isn’t structural. The plaster may feel spongy or crumble. If your plaster is crumbling beneath the paint, it is indicative of a moisture problem and needs to be addressed immediately.

What Causes Bubbling In Drywall
There are two reasons why bubbles form on drywall: problems with the painting process or water damage inside the wall.
The effects show up on any type of substrate material, including wood and plaster. The bubbles are filled with air or water and may become larger over time.
Some wall blisters become hard, while others pop and deflate or drip.
Lets break down some examples of both situations.
Peel Back Paint And Assess The Damage

Why Do You See The Water Bubbles On Your Ceiling
Typically, moisture from flooding would create brown and red stains in drywall. However, a swollen water bubble is the more severe water damage problem. It can happen due to many different reasons:
-Low-quality paint or plaster :
It would be best to always use waterproofing paint for outer walls. Some families often plaster the outside wall with cement, using regular paint. However, when flooded, the house will likely become soaked and moldy. Even when families use cotton skirting boards, it can look dry from the outside, but the wall still absorbs water when it rains for a long time, which eventually penetrates the house and affects the electrical system.
Ceilings are not cleaned or sanded before plastering or painting:
The paint should be applied to a completely smooth and dry wall. If you cover the paint over a rusty, hot, or humid surface, theres a possibility that the paint doesnt stick firmly to the wallboard. As a result, when a leaking situation occurs, water will pile up, get logged in one area, and drop down to the ceiling.
Concrete ceilings are uneven and have concave errors:
This creates a situation in which the mortar layer is too thick in some areas, leading to fragility and a high chance of falling when encountering water damage.
Concrete ceilings have a high gloss and smoothness, resulting in no friction for the mortar to stick to the ceiling:
