We get lots of questions on the subject of silica sand infill material so we thought we’d put together an FAQ guide to sand infill to help answer some of those burning questions and even dispel some of those myths surrounding infills.

If your question isn’t answered here, then leave it in the comments section at the bottom of the article and we’ll add it to our list!

 

 

Do I need to use a kiln-dried silica sand infill?

 

We recommend that you use a kiln-dried silica sand infill for the following reasons:

-It adds ballast to prevent creases, ripples and movement in artificial grass

-It protects and supports synthetic fibres

-It helps to keep artificial grass cool

-It aids drainage

-It increases fire resistance

-It helps to protect the backing material

-It helps to prevent static

What type of kiln-dried silica sand infill should I use?

In the same way you should always choose a good-quality artificial turf, you should always choose a good-quality infill material.

There are many different forms of silica sand infill available and ensuring you choose the correct type will affect the performance of your lawn.

It should be a very fine, sub-rounded grain that will not break down, compact, or damage your artificial turf.

It will also need to be thoroughly washed to help prevent weed growth and remove any impurities.

Using an angular sand can cause damage to your lawn as the sharp edges can cut into the synthetic fibres as you walk across your artificial grass.

Angular sand also compacts with foot traffic, impairing drainage. The multiple edges of angular sand grind together and slowly break down over time, meaning that your lawn will require regular topping up.

Unfortunately, most forms of kiln-dried sand you find at your local DIY store or builders’ merchants is an angular sand, normally designed for use with block paving.

You can buy high-quality, rounded kiln-dried silica sand infill designed specifically for use on artificial lawns here.

 

 

Should I use kiln-dried silica sand infill or DeoFill®?

DeoFill® offers the same benefits as kiln-dried silica sand infill but, unlike kiln-dried silica sand infill, it also helps to control the nasty smells that can become trapped in artificial grass from pet urine.

DeoFill® will only be necessary if you have dog(s) that regularly urinate on your turf; otherwise, you’ll just need to use kiln-dried silica sand.

Typically, if you follow our recommendations when installing artificial grass (i.e. permeable sub-base and no weed membrane beneath your turf) and it’s properly maintained, it’s unlikely that your artificial grass will smell.

However, if your lawn was not installed following the above recommendations or if you have multiple dogs, then the ideal solution would be to use DeoFill®.

Do you recommend using DeoFill® AND silica sand infill?

We recommend using just one type of infill. If you have pets, then using DeoFill® is a good choice, but otherwise we would recommend using a rounded, kiln-dried silica sand.

How much kiln-dried silica sand infill does my artificial lawn need?

This depends upon the grass that you have. If you have a NeoGrass lawn, please follow the below recommendations for our products:

Aberdeen – 4–5kg per square metre

Arena – 4–5kg per square metre

Inverness – 4–5kg per square metre

Delta – 4–5kg per square metre

Libra – 5–6kg per square metre

Tempo – 4–5kg per square metre

Tauro – 4–5kg per square metre

If you have purchased your artificial grass from somewhere else, please consult with your manufacturer. The amount of sand that you should use depends mainly upon the pile height, but also upon pile density and fibre thickness. As a rough guide, please follow the below recommendations:

Pile less than 25mm – 3–4kg per square metre

Pile between 25mm and 35mm – 4–5kg per square metre

Pile over 35mm – 5–6kg per square metre

Please note – this is a rough guide only. Remember, when installing your kiln-dried silica sand infill for a garden lawn, the sand should not be visible in the turf. Please consult with your manufacturer for best results.

How do I apply the infill?

The kiln-dried sand should be applied evenly across your lawn.

For best results, we recommend using a seed spreader to control the flow of sand and ensure an even coverage.

Once applied, you will need to thoroughly brush the fake grass using an artificial grass rake, stiff broom or mechanical brush to allow the sand to fall through the fibres to the bottom of the pile.

Please note – this process should only be carried out when your artificial turf is completely dry.

The sand should not be allowed to get wet during installation, otherwise the moisture will cause the grains to ‘clump’ together, preventing the sand from falling to the bottom of the pile.

 

 

How long does it last?

This depends upon many different factors but, over time, the infill will need to be topped up.

 

 

Will it stick to my feet or the paws of my dog?

If you apply no more than the recommended quantity, then the sand will not be visible.

The sand will sit below the surface of the thatch, resting on the latex backing.

When you walk on the artificial turf, your feet are in contact with the artificial fibres and not the sand. Therefore, sand will not stick to your feet or the paws of your pets.

 

 

Where can I buy kiln-dried silica sand infill?

You can buy high-quality, rounded kiln-dried silica sand infill designed specifically for use on artificial lawns here. You should not use the more commonly found angular kiln-dried sand under any circumstances as it may damage the fibres.

 

 

Is artificial grass sand infill suitable for dogs?

Dog resistant turf

Yes, it is. Some people worry that sand will stick to the paws of their pets and then be walked into the house.

However, as mentioned above, as long as you don’t apply more than the recommended quantities and it’s applied evenly, the sand will be resting at the bottom of the pile, out of sight and out of reach.

Silica sand also has the additional benefit of protecting the artificial grass from digging dogs as it will protect the latex backing, preventing it from being cut by sharp claws.

Artificial grass with a sand infill will also be harder-wearing and longer-lasting, which makes it perfect for a lawn that’s frequently used by pets.
