Filling the Gap Between Traditional Sealants

Published: August 29, 2018

Traditionally, roofing contractors have relied on urethanes, solvent-based silicones, acrylics and thermoplastics to seal and coat roofs and the industry continues to thrive on these products. Let’s find out why.

(Poly-)Urethanes have long been used as a protective coating layer over substrates like smooth BUR, Concrete and Masonry and are popular because of their flexibility, durability and adhesion properties.

Acrylics are great for rougher surfaces, providing a smooth, waterproof sealant.

The Trouble With Acrylics

Acrylics are great for their ability to be applied over a variety of substrates including metal, asphalt, primed wood, concrete, BUR and most single-ply membranes and polyurethane foam. They provide a durable, waterproof, seamless and flexible layer of protection. But they do have their limitations.

Acrylics are not freeze-thaw stable and can not be applied to surfaces where moisture is present. So if you find a leak during a storm, or even when one is in the short-term forecast, an Acrylic is not going to be a good option. If you have a flat or low-slope roof where pooling water is possible, an Acrylic is again, not going to be the best option.

Other Factors That Led to The Need for A Hybrid

Sometimes, jobsites have strict health and safety requirements based on the occupants of the building. For example, a hospital or school building may have restrictions on the Volatile Organic Compounds (VOCs) a product can contain due to the strong fumes it may omit.
