Old timer at the shop showed me his trick for wet concrete edges that never crumble
I was working a residential driveway pour over on Plum Street last Tuesday, and this guy Joe who must be 70 years old walks over. He watches me messing with the edger for a minute, then says "you gotta wet the tool first, not the concrete." I had been spraying the surface like everyone else. He showed me just dip the edger in a bucket of water with a little dish soap, do the pass, then rinse and repeat. The edges came out smooth as glass, no crumbling at all. Has anyone else tried this or got their own weird trick from an old timer that actually works?
