TIL you can fix a hairline crack in green concrete with a wet sponge and some patience
Was on a job in Raleigh last Tuesday and the foreman showed me this trick. I always thought you had to grind or patch those little surface cracks. He just wet a sponge, rubbed along the crack real gentle for maybe 2 minutes, and it disappeared. Said the hydration process still going on lets the concrete kinda heal itself if you catch it early enough. Has anyone else tried this or got a better method?

Last time I tried the wet sponge trick on a hairline crack I ended up just making the whole slab look like a wet dog. I mean it worked I guess but then I had to explain to the foreman why I was standing there rubbing concrete for five minutes. Maybe it's just me but my patience usually runs out right around the time the sponge dries out.

You just kept rubbing until you got results? How long did foreman watch before he said something?

You said "my patience usually runs out right around the time the sponge dries out" and honestly that sums up like 90% of my life right there. It's the same reason I can't follow those 12 step DIY videos on YouTube where you gotta wait for glue to cure for 24 hours between each step. I think there's a whole pattern here where we all want instant results but concrete and glue and paint just don't care about our schedules. Like even my coffee maker takes too long in the morning but I still stand there staring at it. Maybe the trick is just accepting that some things take as long as they take and you can't speed up physics no matter how much you glare at the sponge.
