Shielding Exterior Wall Paint against Sun Damage for a Long Lasting Impression

We do a lot to protect exterior paint of our cars, but we don’t pay desired attention to the dying appeal of exterior walls of our beautiful nest. Just like cars, wall of our house require equal, or should we say, greater care and attention. It won’t be wrong to mention that extra care given to the exterior paint not only makes your home feel more lively, fresh and beautiful, but also protects the wood underneath.
When it comes to outdoor paints, safeguarding it is the key. The paint needs to withstand harsh conditions outside your home. Home owners tend to think that it’s just rain and sun that brings down the beauty and freshness of your home, but dirt and pollution are two other major factors that play very important role in deteriorating quality of outdoor paint.
Whenever we talk about the exterior paint, the first thing that strikes our mind is protection – protection is a term directly proportional to immunity and durability. The paint you choose needs to have characteristics that help it withstand harsh conditions outside.
With constant exposure to the sun and rain, exterior home paint starts eroding. Keeping the walls looking fresh and vibrant all the time feels like a never-ending task until you hire best painters in Auckland to do the job for you. While fighting against eroding effect of the sun’s ultraviolet rays on the exterior walls of the house, you might come across these stages giving you a heads up to looming danger:


As the term suggests, the stage occurs when colour of the exterior paint begins to fade. This process of photo degradation is most noticeable in dark colours. Fading process is very slow, so you might not notice the colour has started to lose its spark. After a couple of years, eventually, you find entirely a different shade on your exterior walls.


This process is successor to fading. Home owners not well versed with the science of paints may mistake it for fading, but a thin white film left behind after a chemical reaction between molecules of paint and UV rays is a matter of grave concern. This thin film makes repainting a problem.


Direct and long exposure to the sun and rain causes peeling of exterior paint. This process occurs when incomplete adhesion (due to chalking) allows moisture to pass through paint and the exterior wall surface. This causes separation. When the sun rays heat the surface, the process of separation becomes faster, leading to peeling.
As we discussed, it’s not just the rain and sun that break down molecular structure of the paint, but also pollution and dirt. You need to be extra careful while getting your home painted, you must choose paint that fights dirt and air pollutants, resists rain, hot summer sun as well as the bone-chilling winters.
If you spend time researching on outdoors paints, you will come across many renowned brands that manufacture exterior paints for walls, roofs, porches and outdoor furniture. Spending wisely on exterior paints not only helps you protect your home from untimely corrosion, but turns out to be a great idea that curbs summer’s rising cost of electricity bills too. Using reflective paints on front façade and roof of home is quite a common practice these days. Using light colours saves on the electricity bills by keeping the indoors cooler in summer.
