The exterior of your home or business takes the brunt of mother nature. The changes of seasons, weather and location can all cause issues for your exterior paint. In order to ensure your exterior paint lasts the test of time, here are some issues to look out for. As well as solutions you can employ to maintain your exterior house or building paint!
Temperature can play a huge part in damaging your exterior paint. It can cause your walls to contract and expand, leading to cracking and peeling. If low quality paints are used for your exterior walls, it is highly prone to cracking. Requiring a repaint sooner than if you were to have used high quality exterior paint.
Temperature also plays a part in determining the best time to paint as well. If it is too cold, the paint won’t dry properly. This can lead to a higher chance of debris contaminating the new paint job. Leave you with a substandard finish on your walls. On the other hand, if it’s too hot when painting the exterior you can find major issues for the finish. A film can occur, so when you or your contractor is painting another coat, you’ll find the initial coat fails to dry properly. This can also result in an unprofessional finish on the walls or other exterior surfaces.
The other problem that can be faced when it is too hot, is that the paint could dry too quickly. I know, sounds like a strange thing that could cause an issue! When the paint dries too quickly, it is prone to create blistering, cracking and premature discoloration of the paint.
The great news is, there are solutions to all of the issues temperature can pose on the finish of your exterior repaint. When hiring a contractor to perform external paint works, ask if you could speak with previous clients. This is one of the easiest ways to tell if their exterior paint has cracked by using poor quality paint. Another way to ensure high quality paint is used, is to ask what brand or range of paint they plan to use. You can conduct quick research on the paint and ensure it suits your needs.
Another simple solution is to ensure the perfect temperature on the day of painting the exterior. The prime temperature to paint is between 10 and 35 degrees celsius. A professional painting company will have this in mind when scheduling your project, however if you approach the project yourself ensure to check the weather on the day you plan to start.
The Australian sun is certainly one of the harshest! Its UV rays cause paint to fade, as well as leading to other issues like chalking. This is when the exterior has been exposed to the sun and weather. Leading to the pigment breaking down and leaving a chalk like coating on the walls. You can also find that the UV rays can cause cracking of the exterior paint. This can occur naturally as the paint ages, premature cracking can be spotted when paint hasn’t been applied correctly. You will not only see cracking, but blistering and peeling can also start to occur due to UV rays – exposing improper application.
The best way to avoid fading of your new paint job, is to select colours that are not too dark. Going back to your year 10 science class, dark tones attract the light and absorb more heat than lighter colours. Using this understanding, you can at least minimise the extent of fading and prolong the life of your paint job. Also look to use UV resistant paint. As this can add an extra barrier of protection for colour fastness, resistance to cracking and blistering of your exterior paint.
Your interior wall paint also can’t escape fading from UV rays. A way to protect the walls in direct sunlight is to look for UV coated windows. This can make a huge difference in discolouration of your interior walls, making them last much longer!
It is quite a treat if you live or own a holiday home along the Australian coastline! However, you must consider how it can impact the exterior walls of your home. The high humidity from living close to the beach can lead to mould occurring on the exterior walls. If left untreated, it can lead to damage of the substrate. This can lead to a much more expensive fix as you would need to look at replacing the entire section of wall or roof!
Another issue the coastal lifestyle can pose on your exterior paint is the salt air. This salty moisture can cause extensive damage through premature peeling, chipping and fading of the paint. You also can’t forget that the sand is like mother nature’s coffee scrub! On windy days or nights, the walls can be sandblasted which will strip the paint. Over time, you will begin to see that the exterior paint will look patchy and be unprotected from moisture.
You won’t have to sacrifice the luxurious coastal lifestyle, as there are ways to maintain the walls. In order to combat mould from high humidity, you can simply power wash the walls and roof every 2-3 months. When looking to repaint the home, consider choosing specific exterior and interior paints that are more resistant to mould. This can be a very easy way to manage this issue from getting out of hand.
When consulting a professional painter, ensure to mention the need for paint that is also more robust against the salty and sandy conditions. A professional that is knowledgeable of the area will be able to show you the variety of options. These options are able to shield the home from sandblasting and salt air for longer.
Moisture in general can certainly be ruthless on your external paint. In high humid conditions, your paint can become discoloured and leave you with a dull finish. When looking to commence a repaint, the moisture in the air can reduce the ability for your paint to adhere to the walls or external surface properly. This will result in bubbling and peeling shortly after the project is completed. Moisture can also be trapped under the layers of paint. So on a hot day when the vapour tries to escape you will find blistering where it has tried to escape.
The easiest way to navigate moisture and ensure your exterior paint job lasts, is to assess protective paints. Amongst the abundance of paint brands available, they have specific exterior paints that will solve discolouration and moisture penetration. Dulux has a variety of paint ranges including WeatherShield and Wash&Wear, while Taubmans has AllWeather and Endure that will combat moisture.
Another easy way to ensure moisture hasn’t been sealed under the paint, is to perform adequate preparation. If approaching the project yourself, do plenty of research on how to best prep your exterior walls before painting. If considering a professional, contact home or business owners near you and ask them what they think of the professional they hired, and the paint they used. They may be able to review or connect you with the best company to get the job done!
