Cutting a major hole in a concrete slab makes a TON of concrete dust! Even though everything was covered (as well as possible) with plastic sheeting, everything got a good dusting of fine concrete powder. I have spent the last couple of days cleaning up using a shopvac, an airhose and a bucket of water w/wet rag to eliminate the mess. I've got two storage shelves to go and all will be back to "normal". The mess would have been worse except for the two ceiling fans and a box fan that blew most of the dust out the front door. At least now I can get in the shop without having to wear a face mask! A few more days and the new concrete will be at 70-80% strength and I can set the anchors for the lift posts (YEA)!
