## Description

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.

Review: This Product WORKS AS ADVERTISED ! - 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.
Review: Fills larger cracks well - Works OK, but a poor color match to my concrete. I used some bits of the old concrete on top for a partial match. Clear might be better than white or random gray. Difficult to fill into small cracks under 1/8", but OK for larger cracks.

## Questions & Answers

**Q: Can this be used on interior concrete basement walls and floors, or is this strictly for exterior use?**
A: Both no problem. It is good for any temp  so you are good to go. I have used it on driveway and for cracks in basement floor.

**Q: Is this paintable?**
A: Yes

**Q: Does it produce strong smells, fumes? I need to apply on holes and uneven setting on indoor apt ceiling. Would it set properly or is the product runny**
A: No smell but I don't know about applying it on a ceiling!

**Q: Do I need a tool to push filler into crack?**
A: This was used to fill cracks in our basement floor. We used a tool to smooth it, but not to force it into the crack, which is great if you can do that. It has been on the floor for some time now and has not cracked again.

Filled the cracks as expected and although it does run a bit on vertical cracks it is easy to work with. Dies quickly again as advertised.
