Well, the sun came out after all! They were able to spray the top layer off the driveway just after lunch today.
It looks good! They made the "lines" (to keep the rest from cracking) curved to match the curve of the driveway. It looks so much nicer than boring straight.
Ami came out to stain the front porch. We found an old paint roller left at the house we're living in by the guy who painted it and attached it to my broom handle to save a LOT of time! And time is money, so that's good. You can see her painting on the porch while the guy was spraying the top layer off the concrete.
