As we all know, everything under the sun has a limited period of existence. This includes us humans as well. When life itself is mortal, then how can you expect objects to stay immortal? But, that doesn’t mean that nothing can be done towards prolonging the life of an inanimate object. The same applies for exterior paint colours as well. People spend a good amount on getting their exterior home painting done only to find that it gets damaged in the long run. Understanding the causes of paint failures in exterior walls can give us a perspective on how to go about with the maintenance of your outer walls. Let’s explore the causes in depth.

Weathering

Exterior walls are constantly exposed to the effects of external weather. This results in chalking and fading. Chalking is the formation of white chalking powder on the surface of the paint film. Due to constant exposure to harsh weather conditions, paint tends to weather away. It loses its functionality. This further leads to loss of grip in the binders. Chalking as a phenomenon occurs frequently with thin coats of paint. After a point, it can completely wear off the entire layer of paint. Fading is another effect of excessive exposure to sunlight.

Moisture

Moisture is perhaps the biggest enemy of good quality paints. Some of the common effects of moisture on exterior walls include blistering, peeling, and mottling. Blistering is a type of paint failure that occurs due to the application of paint coat over a wet or damp surface. Blistering also occurs if there is heavy rain before the paint dries.

Poor surface preparation

Cracking and wax bleeding are the major effects of poor surface preparation. It is one among the many reasons for paint failures. Cracking occurs when the paint is applied before properly removing the previous layer of paint on the wall. If the paint was spread on a rough surface and painting is done without priming the wall, then cracking occurs.

Improper paint application

Scaling and flaking are two direct results of improper paint application. You might get the best exterior paint colours, but if they aren’t applied well, then there is no way that you can avoid the problem of a paint failure. When a paint coating on a moving object, like a door, cracks moisture tends to seep into the cracks causing flaking.

These were some of the main causes for paint failures in exterior walls. Be mindful of these issues while getting your house painted and make sure you opt for premium exterior wall paints for your home. Connect with us at Nerolac for quality and a safe home painting experience.
