What have I done wrong when sowing grass seed?

Hi all,

Are there any lawn experts here who knows where I’ve gone wrong when overseeding the lawn in my new garden?

I carried out the work and overseeded 2 weeks today.

Here’s a breakdown of what I did and with what products

Aerated with pitchfork Mowed low Scarified many times lots of different angles Mowed low again to clean up Leveled where I can with 50/50 soil/sand mix Reseeded about 3kg of “A1 Fine Blade Grass Seed” (link down below) the area is about 60sqm2 toplayer of compost using a spread Watered between 2-4x daily depending if it was overcast or sunny

Here I am, 2 weeks later with just a tonne more weeds, and probably less grass than I started with.

What’s gone wrong? Or do I need to wait more? The bare patches literally have no seed there now, and no growth, so unsure?

Below is a picture of start, during, some progress, and now with the weeds?

It’s a full fescue mix which apprantly takes linger, and requires slightly warmer temps? Could that be it? I do have some slight growth in areas.

Any ideas would be appreciated. Thanks
