The true test of quality in Namgrass artificial grass products is the quality of the latex backing, this is what holds the grass stitches in place and provides the tensile strength making sure your grass yarn stays put.

The process of fitting your artificial grass lawn. It’s important that you follow the established guidelines and advice and must be done right to ensure you get the most value and enjoyment from your artificial lawn.

Full guidelines are available in our How to Install section. Alternatively, you can always speak to one of our approved installers in our Find an Installer section.

Whilst a maintenance free garden is a main reason that many people choose to install artificial grass like anything from time to time you will need to look after your grass to ensure you get the most from it. Here are some tips that you can use to keep your Namgrass artificial grass lawn looking tip-top:

  • Keep it clean: remove leaves with a leaf blower or some people even use their vacuum cleaners to get rid of debris!
  • Good brush-up: use a stiff brush to stimulate the grass pile and make it look newer for longer.
  • Taking care of business: if you have pets, you can take care of their business by simply removing it then spraying away with water.
  • Rotate: if you have equipment that remains stationery we always advise moving this around from time to time to ensure even wear conditions on the grass.


Those pesky weeds don’t give up easily so we always suggest installing a weed membrane to ensure that weeds don’t appear in your artificial grass. Details of how to install this are included in the install video and guide available here.


Our furry (or non furry) friends that it would appear love playing, sitting, sleeping and generally doing whatever they do on artificial grass. If you have pets artificial grass is a perfect solution, there will be no more muddy pawprints and it’s really easy to clean up any mess that’s left. Just think no more dodgy looking brown or dead grass patches. Just a great looking lawn.


Small versions of humans that love to play, run and generally zoom about on our artificial grass products.

Areas for kids to run, play and generally do what kids do best. At Namgrass we are devoted to promoting a healthy outdoor lifestyle and our Namgrass artificial grass products are perfect for use in playgrounds.

This refers to the general feel and ‘bounce’ of the grasses. This will change from one product to the next so it’s always best to see and feel a sample to decide which one is right for you. Some products will be tougher and better for use in high traffic areas. Others may be softer and more luxurious to the touch.
