The make concrete topping mix that is probably your best bet. Home Depot and lowes sell it. It is much more expensive than regular bag mix concrete. Doesn't sound like you need much though.

You need to have a very clean solid surface for the new concrete to grab onto. Powerwashing would be a must.

If your existing concrete is spalling (chipping), that probably won't stop. It is caused by water intrusion and the freeze-thaw cycle in most cases. A bad pour or overworked concrete will often spall. Please understand that you're putting a band aid over something that isn't going to heal. It will probably continue to be a maintenance issue for you every couple years or so.

thank you very much for the information!!

Do you think I should just have the porch redone.

It is about 3 ft above the ground and sits on cement blocks. The top layer of cement looks about 4 inches thick.

It bears looking at for sure. I'd be curious if the cement blocks sit on top of a below-grade frost footing (if you're in a climate that freezes), which would keep the porch from heaving in the cold.

Pouring a small patio is a good DIY project if you're motivated to work that hard!

I was wrong on the cement blocks it is the smaller blocks. They are about 3x6 and about 2-3 inches thick. When ever the proch gets wet it sure takes along time to dry up. I live in Michigan.
