What's This?????

Anyone familiar with this? I’m used to seeing foil tape on seams but this white stuff feels like plaster. New system in new home. Sloppy workmanship? How would you report?



Duct mastic, called “pooky” as a common slang term. Serves the same purpose as duct sealing tapes. Looks ugly, but there’s no pretty way to pooky up duct work. Your pics look like a fairly typical result.


I don’t have ugly in my SOP, does it leak air, if not nothing to report???

Woohoo! I’ve learned something today! Pooky is as pooky does :slight_smile:

Thanks All!

Great sealant, does not leak air, & a bitch for maintanance of the A coil unit. Hope the HVAC guy has more.
