sharp sand is no good in clay soils you need a 70 30 mix of sand and loam
aerate the lawn then top dress working in the sandy loam with a lute

If you use just sand then it'll look like you just tipped a load of
sand over the lawn. I'd go with the sand mix. It won't do huge
amounts for drainage but it'll act like blotting paper and also stop
your shoes getting muddy when you walk on the lawn. With the forecast
drought on the way though maybe you should be looking at something
that'll actually keep the water in?!
