When you’re attempting to settle on a cool roof coating product, it isn’t always obvious which of two similar brands you should go with. Making the right decision means studying both products to see how they measure up in terms of the factors that will most affect their performance, such as their level of reflectivity and how well they will prevent dirt buildup on your roof.
If you are wavering between SW Paints Mastic and Henry 587 100% Acrylic Dura-Brite White Elastomeric Roof Coating, then you may be wondering if there are any decisive factors that you should know about. In this case, however, the choice should be clear. Here’s what you need to know when you’re making this choice.
Henry’s Dura-Brite performs much better on the scrub test than SW Paints Mastic, and it also offers far superior elongation/elasticity. The two products are more evenly matched in terms of dirt pickup resistance and white/reflectivity, but Henry’s Dura-Brite offers slightly better performance in both categories. However, SW Paints Mastic is the winner in bleed-through and the critical factor of tensile strength. So far, there isn’t an obvious winner.
It’s in the adhesion category that one product emerges as slightly superior. Henry’s Dura-Brite scores better in both adhesion to high-quality substrate roofs and adhesion to low-quality substrate roofs. Taking its elasticity score into account, it’s fair to say that Henry’s Dura-Brite performs slightly better in this side-by-side comparison.
