Top dressing new lawn

I had a new lawn grown from seed some 4 months ago, however, it does appear somewhat uneven (I have scalped some patches with a cylinder mower - cutting hight of 17mm)and therefore I am considering top dressing it.
The lawn is grown on clay soil.

Questions:

1. Should I aerate a new lawn before top dressing or will this do more harm?

2. What is the best mixture to use for top dressing, and in what proportion to spread this out?

3. What is the easiest way of doing this in order to get a as flat as possible lawn.

Many thanks for your help.

Just to say I am doing the very same thing 1st week in September. I will not aerate my new lawn as I used a rotavator during my preparation when I sowed my lawn in May. A picture of it is posted in the gallery under 'My Garden' if your interested,

I will let you know what the top dressing mix is, once I have read the relevant chapter in my lawn book tonight!! That's if someones doesn't beat me to it!!!

 

This was taken from the RHS website:

Top dressing corrects surface irregularities and improves the texture of difficult soils, consequently encouraging greater rooting and thickening of turf. A simple mixture is three parts sandy loam, six parts sharp sand and one part compost or leafmould (by volume). Apply 2-3kg per sq m, working the dressing in well with the back of a rake.

 

Many thanks for that. I shall certainly give it a go. Good luck with the lawn.
