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.
