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.

Great product. We had gaps around the perimeter of our house between the house and concrete. We used a spool of foam and then many tubes of this filler on top of the foam. It set up on top of the foam and worked beautifully.

I did alot of research on different sealants. I installed a metal building on a concrete slab and I used this under the bottom rail to prevent water from getting into the building. Works great and says it will last a long time. Very happy I used 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.

Product very good. Returns are worthless - - 20% "restocking fee" come on, what is this 1999? Prepare to keep what you buy, the seller does not accept returns easy and will charge you a restocking fee, like some old timey crap. Will not buy again from this seller.
