How to Install Commercial Kitchen Ductwork Gasket Seal Tape
- Clean the surfaces, removing any old gasket tape and sealant
- Apply a bead of sealant on the metal surface, approximately 1/4" bead
- Use a putty knife or similar object to spread the sealant evenly over the surface of the flange
- Apply the gasket tape to the sealant - press down
- The duct component can be handled and the tape will remain in place
- Time permitting, allow the sealant to cure so it is just tacky.
- Apply sealant to the mating surface of the duct component
- Apply an additional bead to the inner edge of the flange before joining the sections
- Assemble and tighten the flange stud hardware
