In this article, we will discuss the causes of paint peeling, where it can occur and how it can be prevented.
Causes of paint peeling
The most common cause of paint peeling is the failure of coating that could not properly adhere to the surface. However, there are plenty of causes for paint peeling. We will discuss about them.
- First of all we will talk about the preparation of the surface to be painted. Paint peels when the coating is not sticking properly to the surface. If the surface has got some dirt or other substances and it is not properly cleaned, the paint won’t dry properly.
- Secondly, we will talk about the paint to be sprayed or applied. Make sure the paint you are using, are completely mixed well whether it is oil, latex or water based paint. If they do not mix properly, they won’t last long.
- Paint peeling can be caused by painting on a dump or moist surfaces. Water is the worst enemy of painting. If the surface is moist or dump, paint can’t dry properly on that surface.
- The common reason of paint peeling is the poor quality of the paint. Cheap paints can’t stick well on the top of other layers of paint. It can only stick well if it is the only layer on the surface.
- Surface temperature is another enemy of paints. If the surface is too hot while applying the paint, it won’t adhere properly as it should.
- If the coating is not compatible with the surfaces substrate, the paint will break down because of breaking of the adhesion bond. Basically it is caused by the chemical reactions or some other reactions.
- While applying a coating over an existing coating, it may not compatible with the new coating. Some polyurethane, epoxy or other types of chemical coating may not support another layer of coating over itself.
- Moisture is another main thing you need to notice. If the surface transmits a big amount of moisture through itself, the coating will not adhere well.
Paint peeling can be occurred in any surface, any times. It could be an inner wall or exterior wall of a house, a ceiling, off doors, car, furniture even a newly painted one. Any surface could be the victim of paint peeling if it doesn’t meets the right environments.
