Hi, This is my first post here but I hope someone can give me some advice.

We had our parking pad paved and the work was very shotty. It is very rough and looks terrible. The contractor is offering to put a 1/2 inch top coat of Quikrete Sand mix and Concrete Acrylic Fortifier to smooth it out. I am worried that a 1/2 is not thick enough especially for a parking pad and that it would crack and/or pop up due to freezing.

My question is, are my concerns justifed?
