Why Does My Wall Paint Peel Off?

• Expired Paint: Paint's adhesion characteristics may be impacted by component degradation over time. Paint that is too old or expired may not cling to the surface correctly, causing flaking or blotchiness.

• Applying Incorrect Paint: For the best adherence, different paint types are needed for different surfaces. Rich natural oil-rich wood surfaces, for example, can create a barrier that prevents the paint from effectively adhering. Therefore, it's crucial to use wood paints that are designed especially for wood surfaces. Otherwise, if the incorrect kind of paint is used, problems like blistering or flaking may occur.

• Applying Paint on Unclean Surfaces: A dirty surface will not hold paint. Paint application is hampered by oil, grease, dust, or grime. Paint will bubble when applied to unclean surfaces, leading to paint on interior walls or ceilings flaking.

• Paint Job is Too Old: In order to maintain the clean, polished appearance of surfaces must occasionally be repainted. Over time, paint's cohesive bonds strengthen relative to its adhesive bonds. The paint layers separate from the painted surface as a result of this.

After going through these points, I got an answer to my question, why is my paint peeling? It is because the paint job was too old. It was done around 7 years back, so finally, I decided to repaint my walls to give a renewed look to my home.

There can be several reasons for paint peeling off wall. In our case, it was due to excessive moisture trapped in the walls. When we hired a professional, this was the reason he stated. But there can be other reasons as well. Let me highlight a few here. 

Why does My Wall Paint Peel Off?

There can be several reasons for paint on wall peeling off. Aniket has already mentioned most of them so let me add a few more to it:

• Moisture: 

Water infiltration from leaks, high humidity, or inadequate ventilation can cause the paint film to lose adhesion and peel off.

• Poor Surface Preparation: 

Insufficient cleaning, sanding, or priming before painting can result in poor adhesion of paint to the wall surface.

• Low-Quality Paint: 

Low quality paints may not adhere well to surfaces or withstand environmental stresses, leading to premature peeling.

• Excessive Heat: 

Extreme temperatures, especially in areas exposed to direct sunlight or near heat sources, can cause paint to expand and contract, leading to peeling.

• Incorrect Application: 

Applying paint too thickly, using incompatible paint types, or using improper techniques like painting over a dirty surface can result in peeling.

• Surface Issues:

Uneven or damaged wall surfaces, such as cracks or crumbling plaster, can cause paint to peel as it cannot properly adhere.

• Chemical Exposure: 

Exposure to harsh chemicals, such as cleaning agents or solvents, can weaken the paint film and cause it to peel over time.

You can figure out the answer to your query: why does my paint peel off the wall.

I painted the walls in my bedroom a few weeks ago and I was shocked to see my paint peeling off just after a couple of days. It made my room unappealing and old. That’s when I called my interior designer friend and asked him why my paint is peeling. He told me that the peeling of paint occurs when there’s a loss of adhesion between the wall and the paint. It can happen due to different reasons.

Why is My Wall Paint Peeling Off: Reasons

Water is the main cause of peeling paint on bathroom walls and ceilings and exterior and interior walls. It penetrates through the paint coats, separates the layers, and detaches it slowly from the wall. These water sources include bathrooms, clogged gutter, water penetration, water splashes, a leaky roof, etc.

In poorly ventilated buildings, the humidity can cause moisture buildup on the ceilings and walls. On the other hand, condensation brings dampness to the walls, which leads to mildew and mould growth. This is the reason why is my wall paint peeling off.

If you don’t clean the surface properly before painting, then it will cause the paint to peel off easily. The other factors like unprimed or uneven surfaces, improperly placed seam tapes, and incomplete joint compounds can also prevent the paint from sticking properly towards the wall.

Peeling off paint occurs often when using low-quality paint or using paint that is incompatible with the surface, using various types of paint on the same surface, or using too many paint layers.

Excessive dryness happens to the walls when they’re exposed to intense sunlight and high temperatures. The paint dries quickly during the high temperature, which prevents the layers from forming strong bonds.

No paint will last forever! So, there’s a possibility that the paint is peeling off due to the aging factor. This is one of the reasons why does paint peel off walls.

Now you know the answer to your query on “why do paint peel off”.
