Stuck where others failed
Item exceeded my expectations for adhering a cast plate to a polished granite headstone. A bit pricey but worth every penny!

Great adhesion
I used this to stick six mill smooth plastic vapor barrier to the vertical poured concrete foundation wall in my crawlspace. I had the vapor barrier horizontally across the bare ground, then lapped it up vertically about a foot onto the foundation wall, and held the plastic to the concrete foundation with a bead of adiseal. I really didn’t expect it to grab the smooth plastic very well, I thought it would be more like pure silicone and just giving it a little tug would cause it to peel off like a Post-it note. But I was surprised at how well the plastic stuck to the concrete I didn’t try to pull it as hard as I could, because I didn’t want to ruin my work, but I gave it a good tug and it didn’t come loose. It’s good enough to hold undisturbed plastic to my foundation wall in my crawlspace

Strongest adhesive made IMO
This product was as described. I think it would hold up the George Washington bridge at 5:00. Super fast super strong.

Worked excellent for sealing a return fitting leak underwater in a fiberglass pool
This product was well worth the cost it sealed up a leak I had around a pool return fitting in a fiberglass pool where the gasket behind the through wall fitting had failed and was causing water to leak out of the pool. It seems to be holding so far and I would highly recommend it as you can use it on it fitting that submerged in water.

Super hold and clear
I used this to anchor a 1/4 inch tube from an irrigation system in-between a sidewalk crack, then topped it with Gorilla Waterproof Patch & Seal Tape. After 2 months there has been no movement of tape or tube! Even with extreme water and temperatures. Would highly recommend.

Not worth the cost of product
Not worth the 25 bucks sticks to your finger better than to what your trying to seal.

Did not bond well with cement garage floor.
Did not want to drill into garage floor so I got the Adseal recommended for bonding to cement, it did not bond well with the garage floor.
