Although underlay isn’t always required for standard garden installations, many customers choose to include it for added comfort, particularly when laying artificial grass over solid surfaces or for indoor applications.
For the best long-term results, using a suitable underlay can also help extend the lifespan of your artificial lawn. Grass Warehouse underlay has been tested alongside artificial grass for reliable performance and is simple to install.
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.
