We sealed it after we washed it. Rod was in the mood to use the wand rather than the surface cleaner that evening.
We did use the surface cleaner on the kitchen floors (interior) though, had to. The construction crew made a HORRIBLE mess of them, and mopping did no good. He used hot water and the wisper washer and I went behind him with a squeege on a stick and pulled/pushed the water to the drains. What a chore.
Well, gotta scoot.... more later.

p.s. Rod reminded me that he did use the surface cleaner for the outside area to agitate the dirt off the concrete, then used the wand to simply blow off the dirt prior to sealing....
