## Customer Reviews

### ⭐⭐⭐⭐⭐ Fresh and Worked Perfect
*by J***R on February 28, 2019*

I ordered this to seal up a poorly done basement drain following a disaster. I had 2 feet of water in my basement because the house flippers did a crap job. As a result, I was tasked with fixing their mistake. A lot of reviewers had received old product or product that was already solid. Mine arrived fresh and worked to properly seal up the cracks in my cement floor around the new drain that I had installed. The home is over 100 years old so the basement concrete has to be at least that old as well. It had no problems holding and properly sealing everything off. I'd definitely recommend this to anyone needing to do work on porous surfaces because this holds up like a champ.

### ⭐⭐⭐⭐⭐ I have read that epoxy is not good for fixing things that will experience lots of vibrations
*by W***G on March 1, 2017*

I used it to repair a broken button on a toy because manufacturer refuse to sell me replacement part because somehow I might injure myself replacing a broken button. Anyway I needed something that would bond plastic to tin/aluminum and would hold up to lots of vibration because my child likes to pound on the buttons. I have read that epoxy is not good for fixing things that will experience lots of vibrations. The repair is holding up well. This stuff is thick and I had to use a high thrust ratio (18:1) caulk gun to dispense it. I used the remainder to seal cracks in the patio cement. Very useful.

### ⭐⭐⭐⭐⭐ Best caulking compound that I've ever used
*by H***R on December 29, 2018*

I've used tons and tons of caulks in my day. This is the only kind that actually lasts. I use it on my roof and outside and it holds up for years without cracking or peeling as long as you make sure you clean the surface from oils. It's the only caulk I use when I need a caulk that works.
