How To Install Artificial Grass
Here are the 10 steps to installing artificial grass. For the best looking lawn follow each step and be sure not to take any short cuts.
1. Clear any existing grass or vegetation on area for turf, spray a weed killer or grass blocker solution to ensure that no vegetation will grow under the turf area in the future. Armstrong Garden Centers recommends weed cloth. If possible, do this step several days before installation to ensure you removed all weeds.
2. Once you are ready, apply crushed stone aggregate or decomposed granite. You can purchase this at your local rock yard or building supply warehouse.
3. Once the crushed stone is applied, you will want to make sure the base is as level as possible. A water sod roller may be useful for this step. They are available for rental at most Armstrong locations.
NOTE: It is important to remember that the turf will be applied on top of this crushed stone base, thus any undulation on the surface will be visible once the artificial turf has been applied. It is also important to remember that the crushed stone will aid in the drainage properties of the system, so a slight slope is recommended for proper drainage but not necessary.
4. Once the crushed aggregate is compacted and level, use a 15-25 year weed barrier. Lay the weed barrier down using landscaping staples.
5. Once you have laid the weed barrier, roll out the turf according to your area measurements.
NOTE: It is important to lay the turf with all grass fibers or blades going in the same direction to ensure that all pieces of turf match up.
*This step may not apply if you do not have multiple pieces or sections of turf.
6. Make cuts in the turf using a standard carpet or box knife to fit the turf to desired area. You are essentially cutting the turf to create the exact shape of your area, so the fewer pieces of turf used the better; this will eliminate seaming pieces together.
In the event you need to seam the turf together we recommend a 4"-6" indoor / outdoor carpet seaming tape or 6” landscape staples.
7. Now you are ready to attach the turf to your base. To attach the turf to the base use 6" galvinized nails. Drive in the nails 1/2" to 1" from the turf edge and every 4" to 6" along the turf perimeter.
Start at one side of the application area so you can pull the turf tight from the other side. This process is the most important, so your turf is attached securely and properly. Drive in the nails around the perimeter of the area. Install nails 2' to 4' feet in the middle. This ensures that the material is properly fixed to the base. Remember, the nails hold the edges of the turf in place, while the infill will actually weigh the material down.
8. You need to fluff the grass up with a rake or power broom so that the infill can be applied.
9. The final step is to add the infill material, available at your local Armstrong, of your choice. We recommend using approximately 2 lbs of infill material per square foot of turf. You will want to evenly apply the infill material on top of the turf with a drop spreader; if you don't have a drop spreader you can do it by hand but this process will be more time consuming.
We use #30 SandBlasting Sand. This sand does not have dust which is harmful to your lungs. This is a one time application. Then we use Durafill, available at your local Armstrong Garden Centers, on edges to cover nails and gives that finished look.
Silica Sand: Sand that has been tumbled to remove sharp edges
Sandblasting Sand: Sand that has been tumbled to remove sharp edges and screened to remove harmful dust
Durafill: Sand coated with a green poly product
10. Use a soft to medium bristled push broom to work the infill material into the turf. Keep working the infill material into the turf until the turf begins to stand upright. If you do not see the results you want, a flat-head rake is a good tool to use as well.
NOTE: It is important to make sure that you brush the infill material against the grain of the turf; this allows the infill to work its way to the base of the fibers correctly.This is the precision step; you must brush in the infill evenly so its appearance is consistent.
A simple check to make sure it's even is to walk over the turf and your feet will tell you if it's even or not. Work the infill in the turf until desired appearance is achieved. Once the infill is installed. There is no need to add any more for the life of your grass.
