patching concrete floor

[Steve-Maine]

I cut the frost wall of my garage to put in a 11' wide overhead door. The cut is kind of rough. I will need to patch up to 1/2" deep. What is a good material to use. Thanks

Only you know how much you need to fill the voids. Anything sticking up should be chiseled off at or below the intended surface. If there is chalky concrete, or sinderblock, use a rotary
wire brush to make it real tidy/clean. Vacuum to assure no loose material. don't use any that is wet in the container, it will shrink 10% and leave you irritated. Jim
I like this material.
