#Spray the areas with a weed killer. For any existing vegetation (grass and weeds) in the area where you want to lay your turf, start by spraying with Round-Up or a similar product to kill all of the vegetation in the area. Do this at least two weeks before you start your project to give it time to work and kill off all of the vegetation in the area. This will help to ensure that all of the plant material is dead down to the roots. | #Spray the areas with a weed killer.

| − | #Remove the top level of soil. If installing the lawn over soil, dig up the top 3 or 4 inches (7.5–10 centimeters) of sod to make room for the new base. You can use a small rototiller to help you dig up the lawn and break up the soil. Remove all existing grass and other plants, or they may create an uneven surface after they die.<ref>http://www.artificial-grass.com/Frequently-asked-questions.php</ref> | + | #Remove the top level of soil.

#Plan your drainage. Installations over well-draining soil should have few issues with drainage, as the artificial grass should be permeable to water, and the aggregate base described below provides an additional drainage layer. If you are installing the lawn over poorly-draining soil or a hard surface such as concrete, take the following precautions: | #Plan your drainage.

| − | #Moisten and compact the base. Sprinkle the gravel or sand lightly with a garden hose (be sure not to over water) to lubricate the particles in preparation for compaction. Use a plate compactor, roller compactor, or hand tamp to compact the material into a sturdy base, reducing it to 90% or less of its original depth (a drop of about 0.3 inches / 7.5 mm).<ref | + | #Moisten and compact the base.
