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. ## Frequently Bought Together - 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.
