Concrete filler

Would Recommend

Fills in crack in concrete wall effectively. Very gummy-not as liquid consistency as other caulk, so a bit difficult to seamlessly fit into a crack

Works Well

It works well. I used mineral spirits to help keep it soft so I could smooth out in the corner that I was sealing.

In fact it was actually easier to just saw the wood rather than to try and pride apart. Once it’s pressed on and it’s time to cure it’s gonna be there for a long time… Good product if you need to glue something together, my primary use is wood concrete or wood wood. I can’t speak too much else, but ...
