Artificial grass rakes are a great tool for installing fill material.
Infill is an important part of the artificial grass installation process, and there are several good reasons why it should be done.
First, it helps add ballast, which prevents ripples and creases in your fake turf, as can happen when the backing material expands and contracts very slightly at different temperatures. It also helps support the fibers, keeping them vertical. The padding material even helps with drainage, keeps the grass cool in the summer, and protects the backing material.
Installing any type of infill requires brushing off the fake grass to work the infill to the bottom of the pile.
Without a doubt, the quickest and easiest way is to use a mechanical power brush. However, these typically cost hundreds of dollars, so it's not really feasible for most homeowners.
On the other hand, buying a fake grass rake costs less than $20. So, for a fraction of the cost, you can get a tool that is very useful when installing filler material.
