Duct Sealing - Proper Steps Needed
Hello Expert DIYers,
I recently bought a home (25 years old, in Rochester, MI) and spent a summer and a winter in it.
The family/living rooms (1st floor) get enough hot/cold air. I'm happy there.
The rooms in 2nd floor do not get enough hot/cold air, mostly due to the unit being present in one corner of basement and the master bedroom being 2nd floor in exactly the opposite corner.
I also noticed that the area where the furnace is present is much hotter (in winter) /cooler (in summer).
So, I bought UL181 Mastic, UL 181 Foil Tape to seal ducts.
I saw numerous YouTube videos and followed many threads and could not find an answer to this.
1) I'm applying mastic over the duct joints. Do you put the foil over wet mastic or after it has dried?
2) How do you reach the inaccessible areas on the duct (on top of the duct)?
