Concrete countertops ghosting fix?
What I would do is put some 2x4" Southern Yellow Pine or even better Oak framing under to brace those flimsy compressed wood cabinets. Otherwise they will bow out over time.

Then I would get an epoxy based coating for concrete.  They have these in many types, with or without stone, in all sorts of colorings and will look really good and hold up for years. When done you will have a counter you will be proud of as these epoxy coating look really good.  

Usually these epoxy products are two or three parts.  Epoxy, hardener, and sometimes a ground stone you apply over the epoxy.  The epoxy will vary in price from around $40.00 up to maybe $120.00 a gallon depending on what look you go for but you will probably only need a gallon to cover that concrete counter.

Lifetime of these products vary, but I would expect you to want to remodel the room long before the epoxy needs replacement.

In the future when you make a concrete counter make sure to use a sturdy cabinet(s) as concrete is heavy and modern compressed wood cabinets can't take the weight an old wood or even plywood cabinet could.  You should also make sure to tie down the reinforcing mesh so it stays centered in the concrete.
