Bluestar Flexible Concrete Crack Filler (Gray), DIY - No Special Tools Needed, Fill Cracks in Concrete Driveways, Sidewalks, Patios, Garage and Basement Floors. 16 fl. oz. Bottle.

Excellent product easy to use and does the job.goes a long way .

Easy to use and does what it says

More a rubber solution then actual cement.easy to use but if a crack is deep I would use cement to fill most of it and then use this solution.not sure how long this stuff may last,time will tell.will let you know

expensive but the reviews looked good - pored in cracks as instructed on a dry day all sealant has lifted Amazon want me to return the product - how is that possible now it’s in my garden

Bought it for my yard, came off a year later, not very good

Sehr gut, erfüllt seinen Zweck.

Worked as should, filled cracks in concrete nicely

The release mechanism in the blue cap is just atrocious. I've wasted more time fixing it and cleaning around, because too much filler spills from the bottom of the cap, than on actually applying the filler. Do yourself a favour - spend a few bucks more and get a good one.

Unlike other products that I've used to repair cracks in my concrete in the past, this product not only works, it is flexible, it is waterproof, and it is possible to layer it over a 3-4 or 5-day period depending on the depth of the crack and the width of the crack but it really works and it is easy to apply. My only warning to the installer is protect the repair line from feet until the product dries fully because someone can leave footprints in the surrounding concrete if they walk on it too early. I stepped away for 1 minute to get a tool and a FedEx driver walked on mine and left Footprints up to my front door.

Used for some of my gaps in my new driveway. Works well so far. I applied it 2 weeks ago and it seems to be holding up so far and looks good.
