The durability of paint varies based on the quality of paint, the efficiency of the paint job itself as well as the climate and location that you are situated in. Coastal homes, for example, may needed to be repainted more regularly as the exterior is more frequently exposed to sand, wind, salty air and sun. Paint likes to tell stories, so look out for these signs that a new paint job is in order;
Also known as photodegradation, recurrent exposure to the elements (particularly UV light stemming from the sun) changes the composition of the pigments in the paint. Those changes result in a decreased vibrancy and colour intensity. Often, areas that deal with more intense exposure are affected worse than other areas, which makes for an unsightly comparison. If you see faded areas or an overall fade and loss of colour intensity, it is definitely time to repaint those walls!
Blistering paint occurs when the top layer of paint separates from the coatings underneath it. Moisture is normally the culprit, so surfaces need to be dried and prepared accordingly to prevent bubbling. Without the necessary precautions having been taken, any paint finish has the capacity to blister and create bubbles.
Latex and acrylic paint are particularly prone to this, so it is important to have the paint job done professionally and to source paint from reputable paint manufacturers – particularly in a place like Johannesburg where we get frequent bouts of rain in the Summer season.
UV light is the usual suspect again for paint that is emanating a chalky residue. The UV rays weaken the binders in the paint, leaving pockets for the pigment to escape. Sometimes, the binders react when in contact with oxygen which results in a response known as oxidation. Oxidation has the same effect on paint that the UV rays do.
The Ticking of Time
All paint jobs need to be redone once the decay of time has struck. With that being said, quality paint and a vast understanding of its application goes a long way to lengthen the distance between maintenance periods.
