Never hardens under water yes I followed the instructions. I used it to glue two stone structures together. It's like filling a crack with gray putty. I have to be careful not to touch anything while vacuuming or it will move and then I have to reshape it and put it back in the crack. That's it, after a few months I can still take it back and reform it. These are nothing but types of putty that you have to mix to get a different color putty that never hardens.
