Patio concrete repair ?

[Angela Zaitz]

I have a crack running the length of the patio about 1/4 to 1/3 of an inch wide and 40 ft long. I got some filler that looks like caulking from Home Depot. Is a filler the best thing to use? Is there some kind of texture coat paint I can use to camouflage it? It will be a rental, so it will need to hold up well or to be redone easily and cheaply. it is is a desert area that has temp extremes.

Any ideas for me? I would really appreciate your expertise. Thanks!
