Lawn topdressing calls for a measured thin layer that grass can grow through, not an assumed deep fill.
How to plan it
- Measure turf area and exclude pavement or beds
- Check low spots separately from general topdressing
- Calculate the chosen layer depth and order in supplier units
Check before buying: Avoid burying existing grass; address drainage or grade problems first.

Record your site measurements first. Then use a calculator with the depth, application rate, or coverage from the actual material specification.
