	Friday Fax A Weekly Summary of Polywater^® News of Incredible Importance

Issue #722

As promised, this week we offer the second in our series of Polywater Laboratory produced training videos. This 4.5-minute video demonstrates a completely new, alternative method of applying FST Foam Duct Sealant. We call it the FST Foam Saturation Method.

Instead of the traditional application method of using the supplied strips of black foam to create "dams" inside the conduit and to fill the void between them with FST expanding foam, this approach has the installer saturate a measured section of black foam strip with the FST liquid and then install it in the conduit end, where it expands and seals the duct. Watching the video offers a much clearer explanation. A set of Written Instructions was also created for this method.

Why would an installer choose this method over the traditional method? This method works well for vertical conduits (to prevent FST liquid from leaking out of the void before expanding), flowing water (water can sometimes saturate and flow past the first dam before the second dam and FST liquid are in place), and in unusual applications outside a conduit (for example, instead of duct putty around a duct at a wall penetration; putty isn't watertight, but FST is).

Performance of the saturation method is comparable to the traditional method. Seals are strong, air and watertight, and durable. The downside, as seen in the video, is a potentially messy application with greater chance for skin contact. Installers can choose which method is best suited for their styles and circumstances.
