What is the best choice for patching and leveling concrete before tile install?
If you only have chips and small holes to fix, the floor patch and leveler will be a sufficient and cheaper.  

If the holes are minor ( &lt; 1/2" deep and &lt; 1" in diameter), skim coating the area with your thinset and then pulling the notched trowel will safely allow you to bridge with 12x12 tiles.
