7 reasons to keep this 5-gallon pail on hand

By Dani Sheehan. 

From small repairs to preventative maintenance, this roof coating enhances the performance and longevity of flat or low-slope systems. 

If you’re looking to invest in your service department, you need the best products on hand for efficient repairs and maintenance. Low solid rubberized silicone roof coatings offer a flexible and cost-effective solution for addressing common issues like ponding water, minor leaks and normal wear on flat or low-slope systems.  

The clear choice for common ponding water problems is UNIFLEX® Silicone22™ Rubberized Silicone White Roof Coating. A Sherwin-Williams Roofing Solution, UNIFLEX products are designed to reflect the sun’s heat and damaging UV radiation, protecting the environment while extending the life of the building. Silicone22 is a low-solid coating, making it less viscous and easier to apply. Silicone is also known for its elasticity, waterproofing capabilities and resistance to extreme temperatures.  

Here’s why UNIFLEX Silicone22 stands out with its key performance characteristics: 

1 – Elongation: 370% 

This coating can stretch up to 3.7 times its original length without cracking or losing integrity. This helps maintain a watertight seal and prevents damage when buildings expand and contract due to temperature changes. 

2 – Tensile strength: 261 psi 

The higher the tensile strength, the more durable the coating is in its ability to resist tearing or breaking under stress. 

3 – Tear resistance: 23.7 pounds/linear feet 

At 23.7 pounds/linear foot, this coating can withstand significant force before a tear propagates further. Over time, a system with Silicone22 will better resist deterioration from physical impacts and natural wear so that minor damages don’t become bigger problems.  

4 – Permeance: 13.7 U.S. Perms 

This coating is highly water-resistant, but still allows some moisture vapor to escape the system. It’s important for the roof to breathe a little, preventing moisture from getting trapped beneath the surface, which could otherwise lead to issues like mold or rot. 

5 – Solar Reflectance Index (SRI): 103 

In terms of energy efficiency, this coating is through the roof! With an SRI exceeding 100, this coating reflects a significant amount of solar heat, making it very effective at keeping the surface of the roof cool. This reduces the heat load on the building, leading to lower cooling costs, especially in sunny climates. 

6 – Reflectivity: 0.87 

Like the SRI, the reflectance means that this coating reflects 87% of the sunlight that hits it, preventing it from transferring into the building and improving energy savings. 

7 – Thermal emissivity: 0.86 

Together, reflectivity and thermal emissivity create a cooling effect that keeps the roof surface cooler and energy costs down. Silicone22 emits 86% of the heat it absorbs back into the atmosphere. This ensures that even if the roof absorbs some heat, it can quickly release it instead of retaining it, further minimizing heat buildup.
