Our shop in Tulsa still bills by the hour, so swapping the LRU first makes financial sense. It’s a guaranteed fix for the customer and covers our labor if the diagnostics lead to a wild goose chase. Sometimes the old way is just the safer bet for everyone involved.

Honestly, that sounds like a great way to ruin a good pour. You just forced all the bleed water back into the mix and probably weakened the top layer. A little drizzle is better than messing with the slab's water content like that. It might look dry on top, but you've set it up for dusting and scaling down the road. Sometimes you just have to let the weather happen and protect it the right way after.
