Amazing product. Timing worked out perfectly as we were having our house painted. Easy to use and and clean up.

good 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.

I needed to fill 1" gaps at the seams of the concrete around my pool. I first installed the backer rod, then used this non sag product at the end of each seam to keep the self leveling product from leaking out. Very pleased with the results.

It is slow curing, requires some sand or cornstarch sprinkled over the caulk. Bot once it is in the crack, it's not coming out. Gray color blends well with concrete

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.
