Is Acrylic Coating Good for roof Waterproofing?

Roofers applying an acrylic roof coating to large metal roof often referred to as the a basic elastomeric coatings, acrylic roof coatings are generally a popular choice for sloped metal roofs. They are also a serviceable solution for a variety of conventional flat roof substrates including modified bitumen membrane, High polymer membrane, silicone roof coating, and spray polyurethane foam.

Acrylic coating systems are a great solution to restore and protect commercial roofs. There are some important factors to consider when it comes to choosing this particular chemistry. Below, we examine some of the key strengths and weaknesses of an acrylic roof coating.

1. The Advantages of Highly-reflective acrylic roof coatings  


Compared to other chemistry types, acrylic roof coatings are less expensive and just as durable. This means building owners can expect an acrylic roofing system to deliver long-lasting performance, reduced energy consumption, and decreased maintenance costs. This powerful combination of cost and performance is what makes acrylic coatings such a popular and sensible roof restoration solution.

UV ProtectionAcrylic roof coatings are highly reflective and UV resistant. These important qualities can save money by drastically reducing cooling costs during the hot summer months. Minimizing the suns impact on the roof surface not only helps sustain lower energy costs as the system ages but also cools internal building temperatures and extends service life.

Easy to Install

As a water-based substance, acrylics are easy to work with and install. This means an acrylic roof coating system can be installed in a timely manner without sacrificing quality workmanship and with minimal disruption to day-to-day business operations. Also, installation teams will rarely encounter complications with application equipment, making them more productive and efficient.

 2. The Disadvantages

 Ponding Water

Ponding water will negatively impact the performance of an acrylic roof coating. Ideally, these coatings should only be used on sloped metal roofs or roofs with adequate drainage. Installing an acrylic coating on a flat roof can be very problematic if the roof does not drain properly. Before installing an acrylic roofing system or product, it is important for building owners and managers to consult with a specialist to determine if the roof structure will encounter ponding water situations.

Cold Temperature Applications

Acrylic coatings are a water-based product and are more susceptible to freezing in colder temperatures. At the time of application, the outside temperature must be at least 50°F and rising, for the coating to properly adhere to the roofing substrate. Its also worth mentioning that the dry time of an acrylic coating will slow down considerably if the temperature falls below 50°F.

Loss of Mil Thickness

As acrylic roofing systems age, they tend to lose mil thickness as a result of constant weathering and exposure to extreme environmental conditions. Before considering an acrylic product for your roof, ensure that it has undergone proper testing for specific roofing environments and applications.

 3. Conclusion

When it comes to the suitability and performance of a roof coating, its important to understand the strengths and weaknesses of the chemistry. Acrylic roof coatings are a highly effective roofing solution. Theres a number of key factors to consider when it comes to choosing the best acrylic roof coating system for a commercial roofing environment. For more of our acrylic coating kindly contact us.
