Will I have to manually remove weeds from lawn?

Hi, sorry, another thread from me here.

Just wondering, Ive weed killed my lawn in preparation for renovation in september. Will these dead/dying weeds just disappear? will they scarify out once dead or will I have to dig them out?

 

I should clarify. Thing like the little clover leaves I expect will more or less dissappear. I was thinking more about the bigger leafed ones like thistles and the even bigger ones, plantain I think?.

 

I don't know the chemical in it (packet now in bin, but it was evergreen complete soluble,

 

I'm happy that weeds will die, (I've actually just bought some Verdon to hit it again) what I'm wondering is, once dead, will the weeds still need removed? As they are quite sizeable.

 

They'll fall to bits when you rake the lawn (e.g. to get it read for overseeding). If they don't fall to bits then rake it harder
