The ideal temperature to paint a home is 15 – 35 degrees Celsius with little or no breeze and 70-80% humidity. Though as experienced painters, our team can paint well in most conditions. Making sure the paint lasts and keeps in great condition over the years in Brisbane’s climate means attention needs to be given to the conditions when applying the paint and the paint and prep itself.
Painting in cooler weather like Winter means exterior walls will take longer to dry. We take into account weather forecasting and aim to paint when to weather is stable and dry for 48 hours after application. As this will give optimal drying time and set the paint perfectly. If the paint is applied in wet conditions it will not form correctly, meaning issues like blistering, mildew and earlier wear and tear.
Conversely, in hot and humid conditions, the paint will dry faster and not bond properly to the surface making peeling an issue. Qpaint will organise to come early to your home, as we want optimal conditions to paint for a better result for your home. If we paint in hot, direct sunlight the paint will dry fast and make obvious brush marks and blistering.
U.V. radiation and exposure to direct sunlight degrade the binder and pigment in paint, causing colour fading and erosion. Waterborne paint binders resist this damage and are transparent to U.V rays. Solventborne paints absorb the U.V. radiation and break them down. Qpaint will advise you on the best type of paint for your home so you get the best outcome – a beautiful paint job that looks great and lasts for years in the Brisbane climate.
Humidity and Paint
Relative humidity means how much water vapour is in the air compared with how much it can actually hold. For water to evaporate from a waterborne paint it needs relative humidity conditions. In high humidity conditions, surfactant leaching can occur. This is when you can see brown or white discolourations on the surface. High humidity also causes water particles to try and enter the paint surface. For Queenslander homes, this can be a big issue as wood absorbs the moisture easily and can affect the adhesion of paint to the surface making it bubble and peel. Prep work is essential to address these future issues when painting your home. During our quote, we will advise you on any prep work needed to make the paint last for years and years and look good well into the future.
Prep Work on Queenslander Homes
Qpaint regularly paints older Queenslander homes and period homes in Brisbane. Prep work is really important to make sure the new exterior paint job lasts and looks great. Often homeowners want period features which means painting the existing colours. A few examples of prep work needed;
How do you prep your house for painting?
- Colour matching previous colours
- Sanding the surface
- Sealing windows and doors during the sanding process
- Remove previous paint layers
- Washing and preparing surface
- Inspect and repair surface for chips, dents and nails
- Filling gaps in VJ panels with polymer filler
- Paint with primer (latex)
Maintenance Makes Paint Last Longer
Extend the life of your paint job and keep it looking in great shape with regular maintenance. Inspect the caulking once a year and repair/replace any cracked or missing. Remove mould or mildew before it builds up. Wash stains caused by weather or animals and nature (pollen/birds/insects etc). Touch up any blisters or peels to stop them from spreading.
