How can I refinish my 30 year old porch concrete?

Concrete is outside of my sunroom and is part of the house slab. Has cracks, stains and looks ugly. Water will stand on it when it rains. Suggestions needed on how to refur.

Spread the Resurfacer. Fill the walkway joints with peel-and-stick foam weatherstripping, and dampen the concrete if necessary. The resurfacer is workable for about 20 minutes, so mix just half a bag of powder with 5½ cups of water at a time. That's enough to cover two sidewalk slabs, or about 17 square feet.

Stain it with concrete stain. We did our patio and didn't bother with the cracks. Used 2 different colors and it looks great.
