A Dulux AcraTex membrane is a waterproofing system that can be applied to a roof to protect it from water damage. It is a more durable and long-lasting option than roof painting, as it forms a seamless barrier that can withstand extreme weather conditions and is resistant to cracking, peeling, and fading. Additionally, a membrane can also improve the energy efficiency of a building by reducing heat loss or gain through the roof. This can lead to savings in energy costs over time.
One key aspect of a roof coating is its flexibility to expand and contract without deteriorating or separating.
A crucial aspect of a roof coating is its ability to move and flex with the substrate as temperatures change throughout the day. If the coating does not have this flexibility, it will either break apart or detach from the substrate, allowing moisture to penetrate and causing the coating to fail ultimately.
The two main factors that determine a coating’s ability to adapt to substrate movement are its elongation and tensile strength. These properties are improved by increasing the dry film thickness of the coating. This means that thicker coatings are better able to withstand the stresses caused by expansion and contraction of the substrate, making them more durable and effective in protecting the roof from moisture.
As demonstrated in the table you provided, a membrane is a superior option when compared to paint in terms of thickness per coat and elasticity. When evaluating different coatings, it’s important to compare like-with-like. If you are considering a membrane, make sure to compare the test results from recognized independent sources to ensure that the membrane you choose is suitable for your needs.
Another crucial feature of a membrane is its breathability, which allows water vapor to escape from the substrate while preventing water from penetrating the coating. This is important because it helps to prevent moisture buildup within the substrate which can cause issues with mold, rot, or other forms of deterioration. Breathable membranes can also help to improve the energy efficiency of a building by reducing heat loss or gain through the roof.

Features and Benefits of a Dulux Acratex roof membrane
Dulux AcraTex membrane is a high-performance waterproofing system designed to protect the roof from water damage and other harsh weather conditions. It’s a membrane that forms a seamless barrier that can withstand extreme weather conditions, it’s resistant to cracking, peeling, and fading. It’s UV resistant which means it will not degrade or lose its effectiveness when exposed to sunlight, it’s safe for drinking water and also suitable for use in potable water storage tanks.
Solar reflectance is another important feature of this membrane, it reflects a significant amount of the sun’s energy, which helps to reduce the amount of heat absorbed by the roof, this can help to lower the temperature inside the building, reducing the need for air conditioning, and ultimately, saving energy costs.
The membrane is designed to bridge cracks, this means that it’s able to stretch and flex without breaking down, this is important because as the temperature changes, building substrates also move and expand, if a coating does not match this movement, it will either split/crack or separate from the substrate.
Warranty
The membrane comes with a 10-year material warranty, which means that it’s manufactured to last, it’s resistant to pollution, and chemical attacks, and minimizes dirt retention, it’s formulated with premium pigmentation to withstand the effects of the sun, which helps to ensure the longevity of the coating, it also allows for the safe collection of potable drinking water.
Cooling Features
The cool roof feature of the membrane minimizes heat absorption, which helps to keep the building cooler, which can also help to reduce energy costs. The membrane also has a 5 times Dry Film Thickness (DFT) expansion over dynamic cracks, this means that it’s able to stretch and flex more than other coatings, which helps to ensure that it will not crack or separate from the substrate.
Use on different roof types
Dulux AcraTex membrane can be used on a variety of different roof types, including metal roofs, tile roofs, concrete roofs, and asphalt roofs. The system can be applied to both new and existing roofs, making it a versatile option for both new construction and roof restoration projects. It’s suitable for residential, commercial, and industrial buildings. The membrane can be applied to flat, pitched, and curved roofs and is ideal for use on roofs with complex geometries, such as domes, skylights, and parapet walls.
As the membrane is flexible, it can adapt to the movement of the substrate and can bridge cracks, it can be used on roofs that are prone to expansion and contraction, such as metal roofs, which can expand and contract as the temperature changes, which can cause stress on the coating.
It’s important to note that before applying the membrane, the roof should be cleaned, the roof repaired and any leaks should be fixed. The membrane should be applied by a professional applicator who has the experience and knowledge to apply the membrane in accordance with the manufacturer’s instructions.
Colour Fading
Colour fading is a common issue with roof coatings, particularly when exposed to the sun and other weather conditions. The sun’s ultraviolet (UV) rays can cause the pigments in the coating to break down over time, resulting in a faded appearance.
Dulux AcraTex membrane is formulated with premium pigmentation to withstand the effects of the sun, which helps to reduce the likelihood of fading. The membrane’s UV resistance properties help to protect the pigments from breaking down, which helps to maintain the roof’s appearance over time.
It’s important to note that while the membrane is formulated to resist color fading, no coating can completely prevent it. Factors such as the intensity of the sun exposure, the duration of exposure and the surrounding environment, can play a role in the fading process. However, with the right application and regular maintenance, the membrane can help to minimize the effects of color fading and maintain the roof’s appearance for a longer period of time.
