I used this to fix some brick steps with cracked and missing mortar. It fills cracks easily and looks like mortar. It matched the color of the current grout, which is coincidental but appreciated. The only downside I see is that the grout is like vinyl and doesn't absorb water. So when the old grout gets wet and dark it stays the same making it pretty obvious where the repair took place. In the end this is a small issue (for me) and I am happy with this product.
