Hi there!
I have finished diamond-grinding my 36x50 shop's concrete floor. I have a gel filler kit from Legacy for the smaller cracks and such, but there are a few deeper places in the concrete that need filling. These are places where the previous owner had put walls up, and nailed/bolted the 2x4 bottom plate of the wall to the floor. I've removed all of the interior partition walls but there are now some places in the floor that will need to be patched before I coat.
I don't have any pictures handy, but I'd say these places could easily be covered by a Post-It note with plenty of overlap.
At the Big Box Stores I've seen some vinyl concrete patch materials, hydraulic cement, and just regular bags of concrete. None of it costs much so that's not a factor, and I don't mind doing the work, but I'm not sure which one to use. My biggest concern is that I don't want the patch to fail later on, or have adhesion problems with the coating on the patch.
The auto painter in me would probably leave the patch a little below the surface of the floor, and finish the surface with a thin coat of the gel crack filler since I assume (!) I can sand that stuff flush much easier than I can try to get the concrete patch smoothed out flush.
Any thoughts on this are greatly appreciated.
