Replacing an existing lawn surface
Step 1: Make sure the area drains suitably.
Step 2: Use a Turf Cutter to remove your lawn and excavate to a depth of 75mm (3 inches), then weed kill the area.
Step 3: Where there is not an edge or a wall to butt the grass up to use some tanilized wooden battens
(75mm x 25mm). Secure with either wooden stakes or support with concrete to create a boundary around the perimeter.
Step 4: Get rid of any unnecessary bumps or left over debris, then carefully level off the area you wish to cover leaving natural falls.
Step 5: Apply 50mm Astro Grit Sand and level the area, followed by 25mm Astro Silica Sand and level the area again to get a hard surface remaining.
As an approximate guide:
1 tonne of Astro Grit Sand a depth of 50mm will cover 15 square metres.
1 tonne of Astro Silic Sand filling a depth of 25mm will cover 30 square metres.
Step 6: Once level compact it with a heavy roller or wacker plate if available. If not make sure the surface is porous, but firm.
Step 7: Install a layer of Astro Weed Barrier over the surface.
Step 8: Unroll your fresh, new artificial lawn. Stretch over your covering area and leave rolled out flat for ideally 24 hours. This will allow the pre-rolled grass time to settle with any creases time to come out and the pile to settle after being rolled. The warmer and sunnier the weather the quicker this process will take. Once settled carefully cut the boundary with a sharp trimming knife, available from Quickgrass.
Creases – Due to the molecular structure of the material artificial grass does sometimes crease when rolled. Creases will fall out. The grass is not classed as faulty if delivered or installed with creases. The grass will de-crease quite noticeably on a daily basis, especially in warmer weather conditions. Sometimes this can take a number of days.
Step 9: Always make sure you check the pile direction of your artificial lawn. Try laying your lawn in the opposite direction to check the shade from one angle to the next. You may find you like the way your new artificial lawn lays when you turn it around. Always check this before making those final close fitting edge cuts.
Step 10: Add a layer of Astro Silica Sand infill onto the surface so it does not lift from the grounds surface, brush the silica sand into the artificial grass pile with a stiff broom.
Step 11: Once you’re happy with the results, brush pile with a stiff broom every now and then to keep the infill layer from shifting.
