Once the grass has been laid a layer of infill sand, such as silica sand, is spread over the top of brushed up artificial grass. The sand settles to the bottom of the grass blades and sits on top of the backing. It doesn’t change the appearance of your grass when it is evenly applied, and it won’t make the grass dirty. Additionally, the sand won’t transfer to your feet when the grass is walked on, neither will it blow away.
What is the purpose of infill sand?
Using infill sand on top of your grass will help to cool it down. When infill sand is used it sits on top of the backing of the grass, protecting the surface from the sun. The surface of the backing is the part of the artificial turf that absorbs the most heat so when adding sand to the backing it works to cool the entire surface of the grass.
