Round Up is a vegetation killer and it will kill the grass along with the weeds. You may need to dig up the dead grass and replace it or overseed the area. I'd wait about 10 days before doing anything with the affected grass. If only the tops were killed but the roots are okay, the grass will green up on its own. If the roots were killed by the Round Up application, you'll need to rake it out and reseed. A safer product to use on lawns is Ortho Weed B Gon Max. It kills the weeds but won't harm the grass.
