Here's a shot of the repair material after I put it on with a putty knife. You can see the concrete underneath is wet, that's the first step to the process, wetting the area to be repaired. The moisture is drawn into the pores of the concrete, and by starting that process before we place repair material on there it helps the repair bond better. After applying like this we have to wait 20 or 30 minutes before we sponge it off. They use a close-foam sponge or something, and it has a rubber like feel to it. Not your ordinary kitchen style sponge. We have one, but it is starting to fall apart, so I'm going to add that to the list of supplies we'll gather from Hanover this week!
