The Secret Sauce for Contractors: Duct Sealant by Aeroseal

Many people know about the game-changing Aeroseal duct sealing. However, the real magic is in our top secret duct sealant (liquid solution) and how it seals duct leaks from the inside of residential and commercial ductwork systems around the world. Here’s a quick summary about it.

What is Duct Sealant By Aeroseal?

Also known as the Magical Sealant and “Secret Sauce,” our duct sealant is a stable, non-toxic, non-flammable emulsion of water and acrylic polymer that is aerosolized into 4-10 micron-sized particles and distributed under pressure throughout the inside of an air duct system. The following list contains key technical specifications that makes the duct sealant so powerful for contractors:

• Vinyal Acetate Polymer (same base of chewing gum and hair spray)
• Certified in Accordance with UL 1381
• Low VOC Content
• 2 Hours to Cure
• 3-Year Guarantee
• Effective at Multiple Pressures, Temperatures, and Humidity Levels

Mastic Duct Sealant versus Aeroseal (Aerosol) Duct Sealant

Another key aspect of our duct sealant is how it compares to alternatives like mastic duct sealant. Mastic is an older way of sealing duct leaks that is actually not as effective as sealing with Aeroseal. Our sealant is the only option for aerosol sealants that get blown through the ductwork by a computerized system to find and seal leaks from the inside of the air ducts.

One of the biggest advantages of Aeroseal duct sealant over mastic duct sealant is how it’s applied. As pictured below, mastic is applied by hand. A contractor physically has to paint by numbers the mastic on the ductwork. On the right side of the picture below, you’ll see the Aeroseal machine that applies the duct sealant through a computer-controlled process, resulting in less man-hours needed and better sealing results.
