I mentioned Roundup. For that to kill off the old stuff, it takes a week or
two as far as I understand it, it does not really kill off the stuff, but
prevents it from absorbing something the grass needs to grow, so it will
take a while for it to be effictive. There may be some other chemicals that
you may want to look into.
I don't know what is out that will kill off everything fast.

it takes sunshine and good growing conditions to
get the weed killer down into the roots. sometimes
takes more than one application.

smothering with cardboard will work better without
using any poisons.

by the time the weeds and grasses underneath are
dead the worms will break down the cardboard and
the lawn on top will be established.
