I keep purchasing this product
My experience with this product has been great. I have been dealing with a leak where the concrete vault of my Bilco entryway to my basement butts up against my poured concrete basement wall. While this sealer, has exceptional expansion and contraction properties to accommodate temperature fluctuation, it firmly adheres to the concrete surfaces and requires an extensive effort to remove it once it cures in place. I just purchase a 12 tube case for other work around the house.

Great product.
I ordered this product for outdoor fixture. Unfortunately our weather in NY has changed a lot and for some reason I was getting water into the apartment to to some crack on outdoor walls. This did the trick and sealed all this cracks. Looking for something that does the work on sealing. Look no more !!

Old and way too stiff!!! Sitting on the shelf way too long!!
While this stuff is great when new, this batch has obviously been sitting for a long time, and is really thick.Using a regular caulking gun, you REALLY have to squeeze, to the point where your hand hurts after about 8" of bead, even with a large hole in the applicator and sealing "foil" in the tube.
