  • I used it as an easier solution to seal the nails in the shed’s corrugated metal roof, since every time it rained, water dripped inside from several spots. It did a fantastic job, as everything stayed dry during some of the recent heavy rains!
    Of course, I didn’t estimate very well how much I’d need, because I bought 3 and used a little less than 1 :D

  • Today I received it and tested it on the panel on the roof. There is a small leak somewhere at the screw, I applied silicone and sealed it. I will see how it goes and will update you with results as soon as it rains again.

  • I used it to glue marble in an outdoor area. Excellent adhesion and waterproofing. Time will show its durability.
