Color matches well
Would RecommendProduct works well. however it seems to work better for cracks in stucco for me. 4 stars only if wanting to use to caulk along objects as not entirely sturdy

Love this stuff!!! Perfect match!
Used to repair missing tile grout sections after replacing trim. Matched light grey grout perfectly and the sanded texture made it indistinguishable from the original grout.

Works like caulk, looks like concrete/mortar.
Would RecommendLooks just like mortar, but has the give and applicability of caulk! It was the perfect solution between our brand new solid quartz countertop and the existing (very uneven) decorative exposed brick wall.

Super easy to spread around and make it blend in with existing concrete walls. After a little paint, I can't even see where the cracks used to be.

Easy to work with
Would RecommendLooks good so far. Time will tell how long it lasts. A different brand I used previously started to separate from the brick after a couple year.
