How to install artificial grass

Quick Scoop

Installing artificial grass is mostly about good groundwork: clear the area, build a firm base, lay a weed membrane, fit the turf, join seams cleanly, and finish with infill and brushing. A proper install on a sand-and-stone base usually lasts longer and looks more natural than turf laid straight on soil or an uneven surface.

Step-by-step process

  1. Remove the existing lawn or old surface, then excavate enough depth so the finished turf sits at the right level. One guide recommends about 75 mm below the final height for a typical garden install.
  1. Install edging around the area if you do not already have a hard boundary. Timber, steel, brick, block paving, or sleepers can all work, but the edge should sit no higher than the turf surface.
  1. Add a sub-base and compact it well. A common approach is a compacted aggregate layer, then a finer leveling layer on top, with the surface kept smooth and even for drainage and appearance.
  1. Lay a weed membrane over the prepared base, overlapping seams so weeds cannot push through gaps. Some guides also recommend a second membrane for extra protection.
  1. Roll out the artificial grass and let it settle for a few hours before cutting. Make sure the pile direction faces the main viewing area, and keep all pieces aligned the same way.
  1. Join seams carefully if you have more than one piece. Trim the backing neatly, keep a small consistent gap, place joining tape beneath the seam, apply adhesive, and press the turf down firmly.
  1. Trim edges around walls, borders, and obstacles, then secure the perimeter with nails, pins, or adhesive depending on the edging material.
  1. Add kiln-dried sand or another approved infill if your turf type needs it, then brush the fibers upright to help the lawn settle and look fuller.

Helpful tips

  • Do not lay artificial grass directly on topsoil; a stable base matters for drainage and durability.
  • Use sharp blades for cutting, and replace them often so the edges stay clean.
  • Let adhesive cure before heavy use; some installers recommend waiting up to 24 hours.
  • Keep hot objects off the turf, and brush it regularly to maintain appearance.

Common mistakes

  • Skipping excavation or compaction, which can lead to dips and ripples later.
  • Forgetting to match pile direction between rolls, which makes the join visible.
  • Leaving seam gaps too wide or too tight, which can create a noticeable line.
  • Using too little infill or none at all when the product is designed to take it.

Forum-style practical advice

“The base is everything. Get that wrong and the turf never looks right.”

“Take your time on seams. Most bad installs are obvious where two rolls meet.”

Those are the two points most often repeated in DIY installation guides and video tutorials: stable groundwork first, neat finishing second.
