Test your product before injection
I bought two of those to fix a loosing tile in the kitchen. Unlike what most of reviews says, when I opened the bottle, the glue was just thick like tooth paste. It can hardly flow on any surface ! And then I tried another bottle, it was the same !! Not sure if that's just my bad luck, or the whole batch of product in the warehouse had gone bad. I squeezed some of the "tooth paste" on a piece of paper to test, and it had almost ZERO adhesion.
