How much sand and cement do I need for patio concrete?

As a general rule, to mix concrete you'll need four parts sand to one part cement. You might also find this referred to as patio or bedding mortar.

So, for the right mix of patio concrete, you'll need four kilos of sand for every kilo of cement.

But how much of each material do you need?

When ordering your sand and cement, your local builders' merchant will be able to advise how much of each material you'll need for the area you're paving. Just ensure you've measured up the space in advance!

If you're ordering your materials online, a quick search for patio paving calculators will help you work out how much sand and cement you should order for your project.

As a general rule, a tonne will cover 10 sq metres - that's five bags of cement per tonne.

How to mix patio concrete

To mix patio concrete, you'll need to add water to your sand/cement mix until you achieve a smooth, springy mixture.

Ideally, the consistency of your concrete should mean that it can hold its shape. Once you achieve that, it's ready to be spread over your sub-base.

Top tip: Mix up your patio mortar in batches to avoid having to rush and use it all before it dries out. It only takes a few hours for the mortar to dry out and become unusable.
