Paint flaking:
Paint flaking is a damaging phenomenon that occurs when paint cracks or flakes off of underlying structures. Residential or commercial property owners can avoid unsightly painting results and expensive fixes by taking these basic paint application tips into account before they begin painting projects.
Paint can be defined as a pigmented liquid with a liquefiable nature that substrates into a thin layer and converts to a solid film upon application.
The primary objective of paint is to protect, impart color and provide texture to the surface where it is applied.
The defect in which paint detaches from the applied surface is the flaking defect.
In general, flaking may be understood as the phenomenon in which the paint coat does not stick properly on the surface.
The main reason behind the flaking of paint is the lack of adequate bonding between the surface and the film of paint.
1. How To Repair Paint Flaking?
The flaking of paint can be repaired by following the below-mentioned actions:
✔ Firstly, the flaked surface must be examined and thoroughly
cleaned.
✔ The surface is rubbed and cleaned using sandpaper.
✔ Then, the surface is treated with a prime coat.
✔ Finally, the surface coat is applied.
Reasons for Wall & Ceiling Paint Peeling After Painting
Calcimine Paint
If the ceiling of your building is peeling, then it may have originally been painted with calcimine, sometimes called Kal-Kote. Unfortunately, the only paint that is compatible with painting over old calcimine is new calcimine. Otherwise, the paint will not stick and will begin to flake or peel.
Water Damage
If your commercial space recently suffered some water damage, or there is a leak or high humidity in the office, makes the paint peel. Paint does not adhere well to wet or damp surfaces. Also, when plasterboard becomes wet and then dries, after a few rounds of this, it begins to rot and turn to powder. Paint will not adhere to this, either.
Using Too Many Layers of Paint
Sometimes a bad paint job is a culprit of peeling paint on interior walls. One bad habit some painters have is using too much paint so that the paint is layered on too thickly. This is especially bad for ceilings since the weight coupled with gravity speeds up the paint deterioration process.
High Humidity Environment
High humidity in poorly ventilated commercial buildings can cause moisture build-ups in the walls, leading to the blistering of paint. It results in dampness, which stimulates the growth of mildew and mold over time. Improper
Painting Surface Preparation
The painting surface needs to be thoroughly prepared before the paint job is initiated. When the paint is applied on an unprimed or uneven surface, it will start blistering and peeling. Proper prep work is a must if you want to avoid this.
Painting Over Dirty Surfaces
Paint doesn’t adhere to a dirty surface. Dust, dirt, oil, or grease prevent the paint from being applied properly. Applying paint to dirty surfaces will cause bubbling, which will result in peeling paint on interior walls or ceilings.
High Temperatures
High temperatures can weaken the adhesive properties of paint. Exposure to high temperatures can also cause the paint to dry faster than intended, preventing the layers from forming a strong bond.
High Exposure to Sunlight
Exposure to intense sunlight makes oil-based paints vulnerable to cracking. Elastic and latex paints tend to contract and expand when exposed to direct sunlight, which weakens their adhesive bonds.
Paint Used is Incompatible With the Surface
Some surfaces simply aren’t compatible with a certain paint type.
Some synthetic polymer materials can prevent the paint from having full adhesion.
Oil-based paints are affected by galvanized steel and concrete.
Wood surfaces can produce natural oils which can prevent paint adhesion.
Smooth surfaces are unable to form a mechanical adhesion with some paints, so any layers applied to them could peel off immediately.
For this reason, it is extremely important to have experienced painters working on your commercial painting project in order to avoid any unpleasant situations.
Using Several Different Coats on the Same Surface
Different types of paint do not bond well. Applying different paint types together on the same surface can result in paint peeling. Oil-based paints do not adhere to latex-based paints and vice versa. To avoid peeling paint, make sure to always use the same paint type.
Painting Using Low-quality Paint Brands
Some of the low-quality paint brands simply lack flexibility and adhesion. They do not dry or stick properly, and they will start peeling after a short period of time. You always want to choose a paint with a lot of pigment, resin, and fewer solvents.
Incorrect Paint or Primer
Different types of paint are designed for different types of surfaces. There are paints that have been designed for wooden, plastic, metallic, or concrete surfaces. There are also different types of primers available for each of these types of surfaces. Specific primers are designed to be used with different kinds of paints, so using the wrong primer can also lead to peeling.
Using Expired Paint
Similar to any other chemical product, paint tends to expire after a certain period of time. Some paints separate, some grow mold or mildew, while others freeze.
Exposure to Corrosive Substances
Corrosive substances usually contain strong acid or base. If a corrosive substance happens to come in contact with paint, it can cause blistering, cracking, and peeling of paint.
Extreme Dryness of the Paint Surface
Extreme dryness can prevent the formation of strong adhesive bonds that allow the innermost coating of paint to stick to the surface properly. Similarly to painting highly humid surfaces, extreme dryness causes any newly applied coats of paint to peel.
Improper Application Methods
Not using the correct tools or applying a coat of paint that is too thin will prevent the formation of strong cohesive bonds that hold paint molecules together. Hiring experienced commercial painters will save you a lot of time and resources, as you can be certain that this will not happen.
Coat of Paint is Too Old
Surfaces need to be repainted from time
