About Lunar 20mm Artificial Grass

Lunar is our entry level grass, with multi-tone colours and an authentic appearance. It is the perfect 20mm artificial grass option if you’ve never had artificial turf before. Combining different lush green shades, Lunar gives the illusion of short and perfectly maintained grass. Are you looking for a natural looking garden without the hassle of turf? Lunar is a cheap 20mm artificial grass alternative that you won’t regret purchasing. Once your artificial grass is installed, you’ll never look back.

As Lunar is just 20mm, we advise to only purchase Lunar for display purposes and low traffic areas. However, wherever it is, our Lunar artificial grass shines brightly and is very hard-wearing as well as easy to install.


Is Lunar the Best-Quality 20mm Artificial Grass Around?

Artificial grass can be installed on different surfaces, which is why it’s perfect for patios, verandas and balconies as well as lawns or sports areas.

Fitting an artificial lawn

1. Remove your existing lawn and apply weed-killer to the whole area.
2. Edge the area neatly with wood or timber and secure it firmly into the soil.
3. Compact the soil (you might need to hire a whacker or vibrating plate) and add a 50-75mm hardcore layer. If you need extra drainage, use limestone chip instead.
4. Add 15mm of sharp sand or dust granite before compacting again.
5. Pop a weed membrane over the compacted area and attach it to your wooded border.
6. Lay your new artificial grass over the top and trim to fit. Use galvanised nails to fix it to the timber.
7. Brush your grass to raise the pile, so it looks like the real thing.
8. Stand back and admire your handy work!


Other Surfaces 

If your artificial grass is being laid on a harder surface, like concrete or tarmac, clear away any rubbish first so the area’s flat before you start. Then stretch the lawn out and roller it to get rid of any ripples. Once that’s done, use a specialist adhesive to stick it down. We’d also recommend brushing kiln-dried sand (8kgs per m2) into the pile before you start using it.

If you’re not confident about fitting your artificial grass yourself, you’ll be able to find people to do it for you
locally online.


Maintaining your artificial grass 

Like a natural grass lawn, your new artificial lawn needs care and attention to keep it looking its best. Of course, it doesn’t need mowing or edging but there are still things you should do regularly to look after it.


✓ Remove stray leaves and garden rubbish with a leaf blower or by brushing/raking the fibres gently

Keep any surrounding bushes and trees well-trimmed, so they don’t drop too much

Apply weed-killer twice a year, as wild flowers and plants can sometimes poke through the membrane

If you’ve got pets, clean up after them straightaway and use artificial turf spray to get rid of any urine


Any serious spills should be mopped up with a cloth or towel first, followed by a good scrub with washing up liquid and warm water. Use a synthetic brush or cloth on the individual fibres affected and rinse off with cold water.

If the stains dries before you get to it, don’t worry. It can be scraped off with a plastic knife or something similar. An old toothbrush will also do the job.

Your artificial lawn will survive the harshest winter as ice and snow will simply drain away once melted, while hot sunshine won’t fade or discolour the fibres.
