It is well known that traditional dark colored roofs tiles and metal sheet roofs soak up the sun getting hotter and hotter as the day progresses. When the roof space becomes superheated, the temperature of rooms can become unbearable. Due to rising energy costs air conditioning is becoming increasingly prohibitive in terms of both cost and resources.
Amazingly NXT Cool Coat® helps keep your roof and home cooler without sacrificing color and design. This nu-technology reduces the amount of sunlight your roof absorbs, dramatically lowering its heat build up and allows the use of traditional dark colors and light colors.
Unlike other solar reflective roof coatings which only function in white and light pastel colors, NXT Cool Coat® is available in a full color range including all the rich earthy colors used currently by roof tile and colored metal sheet manufacturers that are so popular in Australian homes.
Conventional darker colored roof paint and unpainted cement tiles absorbs between 60% and 95% of the suns infrared heat. New NXT Cool Coat® is a significant technological and environmental break through because it reflects between 37% and 91% of the infrared heat subject to color.
This means that it is up to 70°F to 90°F cooler on the surface of your roof and 43-50°F cooler inside your house.
- Features of NXT Cool Coat®
NXT Cool Coat® contains unique surface nano technology for improved water beading and self cleaning properties. This technology has been incorporated in Nutech’s TileFlex roof coating system for more than 10 years with 250,000 roofs in Australia and overseas successfully restored.
Heat accelerates the degradation of all roof coatings causing a reduction in elasticity, gloss, adhesion, color and other physical properties of coatings. By keeping the coating cooler NXT Cool Coat® technology will enhance and extend the life of the coating. Because the life of the coating is extended, replacement or refurbishment is required less frequently which further adds value to the original job and conveys longer term cost savings to the consumer. This is a winning formula for both the consumer and our environment.
Other features of NXT Cool Coat® include:
- Environmentally friendly water based very low VOC technology.
- Advanced cross linking polymer chemistry for ultra durability.
- Fade resistant micronized pigments infused with saturated color and highly resistant to chemicals, UV light and heat.
- Revolutionary de-foam technology and advanced formula to eliminate micro foam, bacteria and biological contamination.
- 100% waterproof guarantee.
- Drinking Water Safe - NXT Cool Coat is suitable for roofs used for the collection of drinking water for human consumption and for livestock, garden irrigation or gray water toilet or septic tank usage.

- Protect Your Roof with NXT Cool Coat®
There are now two important reasons why you should restore your roof. Firstly, the appearance of your home is greatly improved with a clean glossy colored roof and a durable coating protects your roof from the effects of aging. Secondly you can save money on air conditioning and improve living comfort levels.
All exterior surfaces and coatings undergo an aging process caused by moisture, UV light radiation, temperature extremes, dirt, pollution, moss, lichen and bacteria. This aging can result in gloss reduction, chalking, discolouration, blistering, flaking, loss of adhesion, and unsightly moss and lichen build up resulting in general coating failure.
The key to the success of NXT Cool Coat® is its amazing ability to resist the causes of aging better than any other acrylic roof coating. To repel dirt pick up and contamination this amazing coating stays cooler and develops a non-tacky nano surface film. This nano surface does not discolor and does not affect future recoating adhesion.
NXT Cool Coat® contains highly effective and environmentally safe preservatives which provide long lasting broad spectrum, algaecide and fungicide protection to prevent polymer discolouration and deterioration and moss and lichen growth. NXT Cool Coat® is fully compliant with stringent European and USA biocide legislation.
NXT Cool Coat® contains UV resistant non-fading pigments and tough flexible 100% acrylic polymers which will transform any roof into an attractive and functional surface.
With NXT Cool Coat® you can be confident that you will obtain “a perfect finish” every time.
- Is NXT Cool Coat® better than ceiling insulation?
Rather than allowing the Sun to superheat the roof space, then trying to control heat transfer with ceiling insulation, it is much better to reflect heat away from the surface of the roof. The same principle applies with glass windows. It is better to stop the Sun from hitting the glass with external blinds rather than trying to deal with the problem once the heat has entered your home. In summer external shading is much more efficient at keeping your home cool than internal blinds. Shading your windows from the outside can reduce heat gain in your home by up to 80%.
NXT Cool Coat® works in a similar manner to shading your roof by reflecting the heat before it can enter the roof space. Ceiling insulation will still be required for an energy efficient home but it will work more efficiently as peak temperatures will be much lower.
Coating your roof with NXT Cool Coat® will also maximize the Emissivity of the roof resulting in more rapid night cooling as the temperature of the thermal building mass will be cooler and emit heat to the atmosphere more efficiently.
- Heat Reflective Roof Coating
NXT Cool Coat is the superior coating choice for tiled and concrete roofs. With all the benefits of the NXT Range, Cool Coat is guaranteed to lower the temperature of your roof, resulting in a cooler home.
- Features
NXT Cool Coat is enhanced with Teflon and contains nano-technology for improved water beading and self-cleaning properties. The cooling effect of NXT helps to prolong the life of the coating, resulting in a 15-year guarantee.

- Important Application and Usage Warnings
Do not apply multiple roof coats in very low temperatures or late in the day particularly on non porous substrates such as sheet metal to avoid coating adhesion problems and blistering. Each coat should be independently cured before applying subsequent coats. Do not overcoat primers or sealers including Nu- Prime, SupaPrime, Master Sealer, Metal Primer, GP Primer, SS Membrane, Asbestos Sealer or Nu-Bond until the undercoat is completely dry.
Application in very hot conditions may reduce gloss, affect adhesion and durability and may cause a patchy appearance. The use of NXT Cool Coat® Low Sheen is recommended for metal roofs to eliminate the potential for application banding due to overspray and gloss level variations.
To maximize heat reflecting performance standard full gloss NXT Cool Coat® is recommended.
Nutech NXT Cool Coat® TSR information is based on a comparison of NXT Cool Coat® with conventional roof coatings. Coating a white or lighter colored roof with a much darker color NXT Cool Coat® may not produce acceptable results. Ask your local distributor for detailed advice before purchasing product or refer to NXT Cool Coat® TSR Data. Nutech warrants that the TSR of a specific NXT Cool Coat® color will be better than a conventional roof coating which is a similar color.

Technical Details & Test Data
- How It Works
- Help Protect our Environment with a Socially Responsible Roof Coating
Utilizing advanced technology, NXT Cool Coat® is a high energy efficient coating that reduces summer cooling costs, reduces peak energy usage and helps reduce pollution, fossil fuel usage, land fill and extends building lifespan.
NXT Cool Coat® helps reduce pollution, smog, the urban heat island effect and global warming. Outdoor and indoor air quality is improved due to compliant VOC levels, no Hazardous Air Pollutants and low odor. Unused liquid coating and dry coating can be fully recycled.
To help our environment NXT Cool Coat® is the first roof paint manufactured in Australia is fully compliant with EU and USA regulations regarding VOC content and biocides.
Volatile Organic Compounds (VOC's) are organic compounds found in paints, fuels and some household products. VOC's are a major source of environmental pollution (oCoat) and studies have shown that breathing air with high (oCoat) concentrations aggravates symptoms of people with pulmonary disease and to increase rates of asthma attacks. People with respiratory problems such as asthma, young children, elderly, and persons with heightened sensitivity to chemicals may be more susceptible to illness from VOC exposure. NXT Cool Coat® is classified as ultra low VOC under California’s Clean Air regulations.
In many cases light colored and reflective roofs are not permitted by Council planning controls. These controls are intended to prevent glare for neighbors and for visual esthetics. Council’s often require roofs to blend into the local environment and colors such as green, brown, red and ochre are encouraged. In these cases consumers want the option of having dark roofs including red, brown, terracotta and even black without compromising the energy efficiency of their homes. Until now, design choice has always involved a battle between environmental impact and energy efficiency.
For the first time in Australia NXT Cool Coat® Roof Coating now allows owners to achieve a solution which incorporates design flexibility and energy and resource efficiency. The Australian Federal Government Greenhouse, Victorian Government 5 Star, NSW Government Green Home and WA Government Energy Smart Programs are part of our national environmental policies aimed at saving our limited energy and water resources.
For example, since 2005 the Victorian State Government has required all new residential buildings to meet the 5 Star Energy Rating. Existing buildings are not yet required to satisfy these standards, however the achievement of the standard is made significantly easier with NXT Cool Coat® Roof Coating. These types of controls are being introduced in many Countries as Governments implement responsible building and resource policies. NXT Cool Coat® will contribute significantly to achieve a 5 Star Energy Rating.In 2004 the California Energy Commission estimated that heat reflecting building technology could help save $USD 250 million per year in air-conditioning costs in the Los Angeles region alone. They estimate that the cooling effect in turn would reduce (oCoat) by 4% - 8% saving another $USD250 million in health related costs.
According to Hashem Akbari, a physicist with the Lawrence Berkeley National Laboratory, a 1,000- square-foot roof -- the average size on an American home -- offsets 10 metric tons of planet-heating carbon dioxide emissions in the atmosphere if dark-colored shingles or coatings are replaced with white material. A hot roof increases a building’s energy consumption. An immediate benefit of using NXT Cool Coat® Roof Coating will be energy cost savings. These savings are so significant that heat reflecting roof coatings are now included in the US Environment Protection Authority Energy Star program. Energy Star is a Government backed program helping businesses and individuals protect the environment through superior energy efficiency. Additionally, more and more USA states and communities are including heat reflectivity in building codes and incentive programs.
The Energy Star Program requires residential steep slope roofs (>10° roof slope) to have a solar reflectance exceed 25%. NXT Cool Coat® colors have a solar reflectance exceeding between 30% and 91% depending on the color.
The US Department of Energy research has shown that one additional percent of reflectivity in a coating, on average, will reduce roof temperature by one degree. NXT Cool Coat® Charcoal has a Total Solar Reflectivity of 30%, compared to a conventional charcoal colored roof paint which has a reflectivity of less than 5%. This confirms that a roof coated with NXT Cool Coat® Charcoal will be up to 77°F cooler than a roof coated with conventional charcoal colored roof paint.
Many of the standard NXT Cool Coat® colors also comply with Council Planning and Building controls which often require roofs to have a SRV (Solar Reflectance Value) of less than 40%. White and light colored roofs do not meet this requirement having SRV’s in excess of 70%.
