Vent: A simple patch on a basement floor turned into a 6-hour color match nightmare

Had to fix a 2-foot square where a pipe was moved, mixed the bag stuff to match the 20-year-old slab, and it dried three shades lighter. Ended up grinding the whole patch down, mixing in some concrete stain with the top coat, and feathering it out, which took most of the afternoon. What's your go-to trick for matching old concrete when you can't just pour a whole new section?

Color match nightmare" is right. I once tried to match old paint on a wall and ended up repainting the whole room.

Been there. That's always the final step.

What kind of paint was it? Some of the older oil-based stuff is impossible to match with modern latex. Did you try getting a sample mixed at the store, or just work from a chip?
