Hello,
I hired a concrete crew to pour a slab and they did a really bad job. There are 3 places where there must of been air pockets traped under the surface of the concrete. I scraped away at those areas and removed about 3/16" of the top layer of the surface.
My question is how do I fix those areas where I scraped the surface away? I thought about just mixing up some portland and sand.
Also, I applied an acrylic concrete sealer to the surface of the concrete. If that would make any difference?
