How to patch a cracked, concrete, painted porch?

My front concrete porch has a 1/4'; to 1/2'; wide crack all the way across the top, about 4 feet long. Will hydraulic cement be ok to repair this? Can I feather the edges with a wet sponge as to not show the repair? I will be painting over it, so silicone will not work. Any help will be appreciated.How to patch a cracked, concrete, painted porch?
Is the porch level all the way across? Or did the crack appear because one portion dropped?





If this is the case, you may want to consider talking to a concrete repair service, aka 'mudjack' to have the porch repaired. They would pump a cement slurry under the porch, bringing it back up to its original level.





If the crack is along the edge between the porch, and the home foundation, and the porch itself is in decent shape, then I'd be looking at mortar/cement to fill the gap, or the mudjack to bring the porch back up to original placement.





If the crack runs across the porch itself, and the porch is level over the crack, then I would consider filling the gap with an epoxy. The epoxy would be stronger than cement/mortar.





Place a straight edge across the crack and see if the porch slopes/tilts on one side of the crack etc.... This will also give you an idea as to whether it will be possible to 'blend' the repair in. The more level it is across the crack, the easier it will be to blend in the repair.

take a grinder and open the crack up, then fill with a portland cement mix. this way you can keep it flush with the porch top and not have to worry about feathering it...
