What Customers Are Saying
Customers overwhelmingly praise this concrete crack filler for effective sealing and natural appearance. Most highlight its ability to fill cracks up to 1/4 inch wide, with color matching existing concrete seamlessly and blending well after painting. Many appreciate the sand-like texture and ease of application using a caulking gun, noting smooth flow and effortless cleanup. Reviewers value its flexibility after curing, which helps it withstand concrete movement without becoming brittle. A few report curing issues in deeper cracks, with some remaining tacky, though most still recommend it for reliable repairs.

Would RecommendThis worked great for some concrete patio expansion joints that needed filling. It is still flexible when installed. It also has a gritty texture and can be used to fill a slight imperfection from chipped paint on concrete.

Works great
Would RecommendThis stuff is great! Stays flexible, adheres to wood and metal. I made a paver pad for my table saw and it's framed with 2x4s so it will not move or shift. Very pleased with how this worked, highly recommend it

Would not cure after 2 weeks
Would Not RecommendApplied in a concrete driveway crack approx 1/4 inch wide after cleaning it out. Looked really good at first but then the next day I noticed it was still tacky and soft. The next night it rained and that day the sealant turned into a gummy mess. I blocked off area of driveway and left it in place. Now 2 weeks later its mostly skinned over but still very soft when pressed. It also turned dark gray and looks bad. May end up digging it out and trying another product. Wasted 12 bucks.
Worked great for the use I intended it for gray blocks then painted two tone

Excellent Product!
I used this to fill in two small areas on my brick home. It blends well with the original 100-year-old grout joints!

Other uses
I had to cover an ugly metal strip that was lining an exposed aggregate concrete patio. I placed this product over the metal strip then embedded river rock to into this adhesive product covering the metal strip. It took a few days to cure, but the stones are stuck in very well and it’s very attractive looking. I know this is not its primary use, but boy did it work well. In fact, it worked so well I used it to cover a flaw in the (smooth)concrete edge of our garage floor that was chipped. Well ...
