Tried it on concrete floor and it is a darker color and sets like a rubbery texture. Not impressed. **Q: Would this work to repair a crack in an ‘egg’ bbq?** A: I don't understand the question. As far as I know, it designed to be used on horizontal cracks in cement and blacktop areas. I used it on a cement slab in a condo before I installed carpet. It worked great. **Q: Can it be stained and sealed with the rest of concrete?** A: Our crack filler products will not accept stain. It will accept paint. We recommend a latex based paint. **Q: How to do you clean excess rubber on pavement?** A: The easiest way to remove excess is to score a line between the good and the excess and use a wire brush to remove the filler outside of the crack. ## Frequently Bought Together - Bluestar Flexible Concrete Hairline Crack Filler (Gray), DIY - No Special Tools Needed.
