    It works!
  

*by F***K on Reviewed in the United States on July 1, 2020*

I bought this product hoping to stop a leak in my basement.  There was a conduit with a gas line coming through it that would leak water into my basement.  I used the FST duct sealant and it stopped the leak completely.  Then I noticed another leak from where a water pipe was coming through the concrete wall.  I used FST duct sealant ther as well.  Now, for the first time in a long time, I do not have water coming into my basement when it rains.  It's awesome!  I suggest watching the Youtube video on how to apply.  I had no trouble using it after watching the video.
