Polywater Calculator



American Polywater's
Foam Sealant (FST) Quantity Calculation Page

Introduction: This page will estimate the quantity of two-part FST liquid required to seal a conduit or multiple conduits.  Polywater's FST Duct Seal expands and hardens to a closed-cell foam.  The foam seal keeps water, gases, acids, greases, insects and rodents out of the conduit.  The calculator determines the amount of liquid base required.

The FST-250 caulking tube package has centimeter (cm) markings on the label and the recommended use quantity is in cm. A full FST-250 caulk-style tube contains 8.6 cms of liquid base. The FST-MINI uses a specialty application tool. Each cartridge contains 20 squirts of liquid base. Recommended use quantity is given in number of squirts.

Data Entry: The data input is straight forward.   Select duct size, FST package style, and the number of ducts.  The calculation provides a target quantity for each conduit followed by the total number of packages needed for the whole job.  See www.polywater.com/FSTuse.pdf or www.polywater.com/FSTMINIuse.pdf for installation instructions.
