I’ve used two brands of this caulk-tube concrete crack filler and I can’t remember which one was great and the other was terrible.
It has a predominately safety yellow and black colored tube.
One was from Home Depot and the other, Lowes. I’m guessing the Lowes product was better.
If in doubt, buy both. You’ll need more than one tube. 😉
