Okay! So to correct myself, I used Rock Solid Fast Patch kit. Bought it at Menards. I used it to repair spalling and as a finish for the large patch I mentioned I had to do. For the buildup patch I used Sakrete Fast Setting Cement Patch. This stuff can go on thick to repair the edge you pictured. This is where I'd etch, rinse and apply the product. The key is to keep it moist while it cures. I used plastic taped to the floor to hold moisture while it cured. You might consider using a concrete bonding additive. All pictured below.Hope this helps
