What is the Difference Between These Two Sealants?

By Cass Jacoby. 

Titebond’s® WeatherMaster and DuraMaster are two of the brand’s top-performing sealants. Both are paintable, versatile and VOC-compliant, but other than that, what are their differences? 

These two sealants, they share one main commonality: high performance. While both products are excellent choices for siding, window and door applications, there are some main differences between each Franklin International/Titebond sealant that makes it unique. Read on for information on what makes these two sealants so special. 

WeatherMaster™ 

This is an advanced polymer sealant and is recommended for exterior use. As opposed to water-based sealants, this product can be installed in freezing temperatures, rainy or wet conditions and can even be applied in standing water. Cold weather isn’t an issue with this sealant as it can be applied in zero-degree weather. WeatherMaster comes in more than 200 colors to match popular siding colors. 

DuraMaster 

This sealant, on the other hand, is a Class 100 water-based elastomeric sealant for interior and exterior use that can fill gaps up to two inches. DuraMaster is the first water-based elastomeric sealant that is resilient enough to maintain its hold even with high amounts of movement. It can manage 100% expansion and 50% contraction, making it the first sealant with 100% joint movement capability while maintaining adhesion.  

DuraMaster truly is in a class all its own, as the first sealant of its kind to achieve the highest ASTM C-920 rating for sealant performance, Class 100/50 (expansion/contraction). 

As more homeowners demand stronger and more sustainable roofing options, the performance of sealants for metal roofs has become a critical to roofing quality. You need a sealant that will really hold onto the metal even as it expands and contracts, which is why both of these high-performing products are just the thing to give you solid assurance of your home’s roofing durability.
