low spotin slab

Building sun room/den over old patio. It is walled, roof is on, now I find one problem, the slab has a low spot where the door is. I need to raise slab at door 1/16" to keep water from backing up against door sill. I can raise it up 1/2" but will need to feather it out to real thin. I have 17" to feather a 1/2" rise at door sill to as thin as I can get it at slab edge. Has anyone had experience with Quikrete concrete patcher and Quikrete adhesive or any better suggestions.

Use a latex modified patching material, and score the surface to be patched. Is appearance an issue or will it be covered?
