Calculate the size of the area that you want to replace in square metres. Work out how many rolls of grass you will need by drawing a diagram. Position the rolls to minimise joints and allow some extra lawn length for wastage. Remember, all rolls should be laid in the same direction and ideally so that you are looking into the pile.
Preparation of substrate:
Lay your grass on a 35mmm layer of compacted sharp sand. If required, remove an equal amount of topsoil to maintain levels. Remove any vegetation to prevent uneven rotting. Use the back of a shovel or a vibrating plate compacter to compact the surface.
Lay the weed membrane directly under the grass. Take it right to the edge of the area and overlap it by at least 100mm.
Lay the artificial grass on top of the weed membrane. Allow approx. 50mm surplus at edges so that you can trim perfect edges. It is advisable to now leave your grass to settle for 24 hours in order to prevent creasing.
When joining, butt any grass edges together and then peel the grass back to lay fibreglass backing under the join. Apply adhesive to the tape and then fold back the grass taking care not to squeeze the adhesive up onto the grass strands.
Cut and trim your artificial grass, making sure there are no gaps between walls and grass. Use a sharp craft knife to do this, changing blades regularly.
To anchor the grass, nail ground pins at an angel into the ground every 200mm to secure the perimeter.
