I'm having a section of my sidewalk repaved this afternoon in front of my house - How many hours do I have to sit out front and watch my new cement before it's hard enough that little Johnny can't carve his name in the new cement?
Weather will be a high of about 60 degrees with high humidity, no precipitation if this is relevant. I have a cigar and 4 pack of Murphy's Irish Stout standing by with a lawn chair. Advise. |

I have pulled all nighters watching walks on Halloween.
Didn't need some little punk scratching their initials in it. With the conditions you described it will be green well through tomorrow, and anyone with a stick or rock could still vandalize it. I have had a guy walk across a walk I just broomed on hour prior though and not even dent it. It was 95 and sunny out that day though. |

It also depends heavily on any additives in the concrete. Some can shorten the cure time and some can delay it. I do field testing of concrete, but its exclusively for bridges. I don't have much experience in sidewalk concrete. Most guys won't doctor up residential mixes. My go to mix is just 4,000 lbs with #1 stone. Maybe 1% non-chloride accelerator and hot water when it's cold, but it causes "rubber floor" so I don't like to use it if I can avoid it. However, that same mix on a day in the 60's will make it walkable in short order, but the installer will be hauling ass to get it finished. |

In a funny and somewhat related story.
We helped a guy put in a bunch of sidewalks one time and he had his guy watch them afterwards. The next morning someone had scratched two sets of initials inside a heart into one of the blocks, they had to work at it too, they must have use a rock. He went and looked at all the mail boxes on the houses and found the one with both sets of initals (the retards were only about 3 houses down) and spray painted his initials on the front door. He knocked on the door and a young guy answered and he said "Now we're even" It was at the same time one of the funniest an ballsiest things I had seen. |

one of my neighbors has his daughters' names carved 3/4" deep, 1/2" wide and 3" tall in his driveway. He's still mad about it. My old house has two of my dog's footprints in the driveway, very faint, more of just a difference in texture than a depression.
