How much grass seed is too much?

Question

I'm told by my seed supplier that it's impossible to to put down too much seed when overseeding an existing lawn or seeding a new lawn for the first time. Assuming the cost of seed is not an issue, is it possible to put down too much seed?

Answer 1

Sure- when you start stacking seed on seed, so some seeds don't have ground contact, it's clearly too much.
