no, only asphalt.
Cure time is temperature dependent. In my experience it took several days mid July to cure. After cure, the material had shrunk so much that it was almost as thin as paint and did not fill the crack. Cracks filed were about 1/8 inch wide and 3/4 inch deep. I was not happy!
No caulk will allow staining after application. I would suggest filling the cracks with cement (No gravel) and then stain. I would also warn you that unless the stain is fairly dark, the areas that were cracked will likely be at least slightly different in color than the rest of the existing concrete.
NO! For asphalt only, such as roads and driveways.
After 2 days of cure in my latest application debris that blows onto it does not stick. A blower blows it right off. I doubt you need to worry about that.
It somewhat depends on how deep the crack you are filling is, but typically you are ready to go in 2-3 hours.
I used a plastic trowel and work it just as it came out of the tube, keep the trowel angle against the tip of the tube when applying it the pressure will force it into the crack.
Dunno'. I'd be concerned that the asphalt nature of the product would bleed through any paint. If you're gonna' paint i you're probably better off with a caulking, like Lexel or a paintable polyurethane like Sikaflex. This also does shrink, making painting more problematic.
60degrees or warmer. However I found this stuff dries fairly quickly to the touch 4-5hrs and firmly overnight approx. 12hrs =
