I. Sub-Base Preparation
A. Remove existing sod and soil to desired grade. To remove a slope, read How To Level A Slope For Putting Green & Artificial Grass Installation.
B. Add approximately 10 lbs. of base for every square foot of green or grass. (Minimum of 10 lbs. per square foot) Common names for the base are: #8 crusher rock with fines, 3/8″ minus with fines, marble chips with fines (the largest stone in the mix can only be 3/8″). Fines are all of the smaller particles of stone down to the size of sand. Do not use pea gravel or pure sand. This base will promote drainage and provide a smooth surface. For wetter climates and softer soils or large jobs, a sub-base of up to 6” of road gravel topped with the sub-base above may be the best practice.
C. Compacting the aggregate is recommended. Use a hand tamper for small areas and a vibrating plate or water filled roller for large areas.
II. Setting the Grass (see Seaming IV if necessary)
A. Stake or nail the grass edges every 18” around the perimeter 1″ from the edge. Use landscape spikes or 6″ aluminum or galvanized nails. In high wind areas, more staking may be necessary.
B. Rake (soft rake) or brush the fibers against the grain to stand the fibers up.
A. Artificial grass turf has a grain because of the manufacturing process and the fact that it is kept on a roll. MAKE SURE ALL THE ARTIFICIAL GRASS GRAINS MATCH BEFORE CUTTING (go in the same direction). A drawing to match the grains is recommended.
B. Synthetic grass can be cut with many cutting tools: (fresh blade) razor knife, carpet knife, etc; however, THE ARTIFICIAL GRASS BACKING HAS VARYING THICKNESSES. USE EXTREME CAUTION AND DO NOT PULL THE CUTTING TOOL TOWARD THE NON-TOOL HAND OR YOUR BODY. SEVERE LACERATION MAY OCCUR.
C. Artificial grass edges may be trimmed or contoured with sheers or scissors especially when seaming border grass to the lower pile height putting turf.
A. Lay the cut synthetic grass pieces out and place the seams together as desired (match grains). There are many ways to seam artificial grass. We recommend our 12” wide seam tape. The glue must be a polyurethane base glue or adhesive (we recommend Loctite Heavy Duty Construction Adhesive 3x, Liquid Nails Heavy Duty Construction Adhesive or 3M Rubber and Gasket Adhesive. Place the tape on the seam line half-way under each piece of the synthetic grass, lift up edge of grass and apply glue to ½ of the seam tape with an “s” shape. Press the artificial grass to the seam tape. You may want to weigh down the seam with bricks. Allow to dry to a point where it is firm and then glue the seam tape and other side of synthetic grass together. Remember to stand on the side of the tape you are not gluing or it may cause bunching on the tape. Keep the artificial grass fibers out of the seam, and don’t use so much glue that it gets on the grass. If you are experienced, you can do both sides at once. Remember, you are gluing the synthetic grass to the seam tape and not the two pieces of grass together. Allow seam glue to dry thoroughly.
A. Infill is not necessary for small jobs but is highly recommended. It improves the look, weight, feel, drainage, life expectancy, and makes the blades stand up straight.
B. The best infill is play sand. A fine to medium grit sand with no small stones.
C. When the seam glue is dry, disperse infill as desired up to ¾ of an inch (3 to 4 lbs. of sand per square foot of grass is recommended). Broadcast the infill evenly across the artificial grass and back rake the grass against the grain to stand the blades upright. Infilling may shrink the synthetic turf coverage.
A. StarPro artificial grass has 1/4″ drain holes on 3″x6″ centers and drains at 25 inches per hour!
Notice: Local or neighborhood codes, covenants, restrictions or specifications may apply to the installation of synthetic lawns. Local municipalities may offer incentives for the installation of synthetic turf. Check with your local government or water company.
