Ever thought a house or building would look great painted in a sleek, dark colour – then had to shelve plans for fear of the heat damaging the substrate or the building getting unbearably hot in summer?
Resene CoolColourTM technology makes painting exterior surfaces in dark colours both easier and safer. It can be used on all sorts of exterior materials and applications, from weatherboards and concrete to windowsills. A Resene CoolColour looks like a normal colour but thanks to special pigment technology it reflects more heat, so it doesn’t get as a hot as a standard colour would.
When looking at the role paint can play in temperature control in buildings it comes down to colour. The ability of white to reflect visible light extends through the infrared and, because of this, white surfaces remain relatively cool to touch, even in direct sunlight. The opposite is true of black and dark colours, which absorb light in this infrared area, resulting in significant heat build-up in the surface. As the emissivity of paints is not particularly good, the surface heat is conducted into the substrate and then radiated into the building.
A Resene CoolColourTM uses pigments that reflect more of the sun’s energy resulting in the same visible light reflectance value as the standard colour but a considerably higher Total Solar Reflectance value.
First developed for high gloss roof coatings, Resene CoolColour technology is now available in a range of paints and stains. These include Resene Lumbersider waterborne satin,Resene Sonyx 101 waterborne semi-gloss, Resene Hi-Glo waterborne gloss, Resene Summit Roof waterborne satin, Resene Enamacryl waterborne gloss enamel, Resene Lustacryl semi-gloss waterborne enamel, Resene SpaceCote Flat waterborne enamel,Resene X-200 waterproofing membrane, Resene AquaShield mineral effect, Resene Waterborne Sidewalk paving paint and Resene Waterborne Woodsman wood stain.
The finishing touches
Doors and windows are a hardworking part of your home – they are prone to the weather and mechanical action as they are regularly opened and closed.
Resene recommends Resene Lustacryl semi-gloss waterborne enamel for most door and window joinery painting projects. It is a waterborne finish so performs well outside but is also a lower sheen than Resene Enamacryl so will hide more surface imperfections.
If you prefer a stained finish, Resene Kwila Timber Stain or Resene Woodsman Wood Oil Stain are also popular options but will need recoating every couple of years.
