What Is Wall Water Damage?
This is a situation when the walls get damaged because of water penetration within them. This water can come from inside because of a burst pipe or outside like a storm. If left unaddressed, it can lead to severe structural damage and the growth of molds.
Hence, as soon as you witness this issue in your office, house, or another space, you must seek professional aid.
What Indicates Wall Water Damage?
Just like any other issue, wall water damage has its symptoms and indications.
Let’s glance at them!
1. Discoloration- A damaged wall tends to discolor over time. Short streaks of distinct colors appear on the surface. The discolored area shows soft spots.
2. Water Bubbles- This is the most common and severe problem that occurs because of water clogging behind the pools and paint. It stretches the paint across the surface. This results in the appearance of small bubbles and if the water continues flowing through the surface, it can lead to holes in the walls.
3. Softened Drywall- Softening occurs on the backside of the drywall. The exterior paint, however, appears normal. If you suspect water damage in the wall, you may press against the drywall. When there is a depression or buckle, it is because of wall water damage.
Why Do Water Bubbles Appear On The Ceiling?
Water bubbles on the ceiling usually appear because of excessive moisture within the drywall that creates red and brown stains. The problem becomes severe when swollen water bubbles appear on the walls. This can happen because of many reasons:
1. Improper Sanding Of Ceilings Before Painting Or Plastering
You must apply paint to a dry and smooth wall. Avoid applying paint on humid, hot, or rusty surfaces as this will not stick the paint firmly to the wall. In a leaky situation, water stocks up and gets clogged in one area.
2. Poor Quality Plaster Or Paint
It is best to apply waterproof paint to walls. A lot of homeowners use cement with regular paint. But this does not work when the weather is moldy and soaked. Even if you install skirting boards, the wall absorbs water that ultimately penetrates within.
3. Concave Errors Or Uneven Concrete Ceilings
This is a situation where the mortar layer is thin in some areas and thick in others. This results in fragility and more chances of experiencing water damage.
4. Excessively Smooth And Glossy Ceilings
Sometimes contractors use roll waste oil and bamboo boards before formwork installation. This is done to ensure avoiding corrugating iron.
Reasons For Blistering Or Bubbling Paint
Bubbles under the wall paint can appear because of various reasons. Below are some of the common causes of the appearance of paint bubbles.
1. Applying the Paint on a Dirty Surface
The most common reason for the occurrence of bubbles under the paint is that you have applied the primer and paint on a dirty surface.
The surface may appear clean, but when paint reaches its depths, it extracts impurities, which get visible in the form of bubbles.
2. Forgetting To Apply Primer Before Paint
Applying paint before using a primer is another common reason for bubbles appearing on the wall. The primer must be applied as plaster or raw wood so that they soak the binder and pigments in paint. This also gives you an even and streak-free finish.
For wall paint works, the primers are the foundation without which you cannot expect a perfect result.
3. 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.
4. Using Excessively Hot Materials
Heat can result in bubbles under the paint. Excessive heat can be because of using a hot primer, painting, or painting on a hot wall. It is because when the paint comes in contact with a hot surface it unnaturally expands.
What You Must Not Do With Paint Bubbling On Wall Water Damage?
- Bursting wall bubbles can release the accumulated water and make the condition worst. This can cause internal damage to the building.
- It is best to hire restoration experts who can dehydrate the affected parts and repair your wall using relevant structural materials.
- Avoid poking the hole yourself as it can drain out water. You may, instead, apply a dehumidification process. This procedure dries out the moisture and ensures you have clean walls.
- Timely contacting the professional can help restore the property and save you a good amount of money and time.
