Firstforturf artificial grass is supplied in 4m and 2m widths and up to 25m length. To cover the area in the example would require a strip of grass 4m wide x 8.1m length and another strip 4m wide x 5.1m length. We always recommend that you add at least 0.1m length onto each strip of grass to prevent leaving yourself short. You should also ensure that you lay the grass running in same direction with the pile direction facing your main focal point.
To complete the join in this example requires 5 linear metres of joining tape and two cartridges of glue (One cartridge of glue covers approximately 3 linear metres of tape).
