Hello GreenThumbs_NOT.
I think there is a fairly easy way to spiff up your porch.
Quikrete Concrete Resufacer is a Portland cement based product designed for making thin layer repairs to and for restoring the appearance of existing sound concrete surfaces.
These are quotes from the Data Sheet for this product. You can find the entire document here.
You will want to rent a pressure washer to thoroughly clean the porch before applying this product.
Take a look at the links and see if this is something you want to tackle.
I hope this helps,
Newf.
