Frequently Asked Questions

What exactly is a 70/30 mix?

It is a blend of 70% heat-treated sand and 30% sterilised loam (soil). The sand ensures excellent drainage and a level surface, while the loam provides the nutrients and moisture retention necessary for grass to thrive.

What are the main benefits of using top dressing?

Applying this mix serves three main purposes:

  • Levelling: Fills in minor bumps and hollows.

  • Drainage: Improves surface water movement, reducing ‘squishiness.’

  • Renovation: Provides the perfect medium for new seeds to germinate during overseeding.

How much coverage does a 25kg bag provide?

Coverage depends on spreading technique, but generally:

  • Light dressing: 2 - 3kg per square metre (covers approx. 8 - 12m²).

  • Heavy dressing/Levelling: 4 - 6kg per square metre (covers approx. 4 - 6m²).

When is the best time of year to apply it?

You should apply top dressing when the grass is actively growing, typically in spring or autumn. This allows the grass to grow through the dressing quickly. Avoid applying it in the dead of winter or during a summer drought when the grass is dormant.

Do I need to prep the lawn before applying?

For the best results, yes. It is recommended to mow the grass short and scarify or aerate the lawn first. This allows the dressing to reach the soil surface rather than just sitting on top of the grass blades or thatch.

How do I apply it evenly?

You can use a drop spreader for a very light dusting, but for a 25kg bag, most people use a shovel to broadcast it and then a levelling rake or a stiff brush to work the material down into the sward (the base of the grass).

Can I use this for overseeding?

Absolutely - it’s the best partner for grass seed. Spreading the seed first and then applying a light layer of 70/30 top dressing protects the seed from birds and keeps it moist, significantly increasing your germination rate.

Is this product safe for pets and children?

Yes. Since it is a natural blend of sand and soil, it is completely non-toxic. However, you might want to keep the dog off it for a day or two just to prevent them from trailing sand back into your house!

Why should I use this instead of just plain topsoil?

Plain topsoil can be too heavy and may contain weed seeds or large stones. It also doesn't improve drainage well. The high sand content in a 70/30 mix ensures the surface stays firm and free draining, which is why it's the choice for golf greens and football pitches.

Does it contain fertiliser?

Standard 70/30 top dressing is generally un-fertilised to give you total control over your nutrient programme. However, the loam content does provide some natural organic matter.
