Step 4.)
Seam the edges and infill installation (if needed)

SEAMING

1. Fold the adjacent trimmed edges of two rolls of turf approximately two feet apart the entire length of the seam.
2. Mark the centerline of the seam on the exposed base with a chalk line or spray paint.
3. Roll out seam scrim or tape centered over the entire length of the seam line. Apply adhesive covering all of the seam tape from one end to the other. Depending on the type of adhesive used, you may need to allow time for vapors / gases to escape (flashing). Refer to the adhesive manufacturer's directions. The flashing time required may be dependent on ambient temperature and humidity.
4. After adhesive has flashed, lay the edges of each roll of turf directly onto the adhesive/tape, making sure not to bury any grass fibers into the adhesive.
5. Be sure to add weight (i.e. sandbags or rubberbags) down the length of the freshly laid seam, or use a heavy roller along the seam length. The adhesive drying / curing time will vary with different adhesives dependent upon climatic conditions.
6. Caution: Too much fiber exposed (not enough infill) will cause the fibers to mat or crush with heavy foot traffic. This will lead to premature wearing of the fiber and will void any manufacturer's warranty.
7. There may be more than one type of infill used on the same site. In many cases, a combination of silica sand and granulated rubber, or silica sand and manufactured sand top dressing, may be used in layers. In either case, the silica sand is installed first, followed by the granulated rubber or top dressing.
8. Be sure to follow the site specifications outlining the amount or depth of each infill material.

INFILL INSTALLATION

1. In synthetic lawn applications, a drop spreader (commonly used to spread grass seed, fertilizer, lime, etc.) should be used to spread the infill in lifts ranging from to no greater than half and inch (½") depths. In between the spreading of lifts or layers, the fibers should be brushed upright with a plastic bristle industrial broom or a power-broom. This keeps all of the grass fibers erect and exposed. Fibers trapped underneath the infill may not ever be recovered.
2. Do not use stiff steel bristle brooms that can damage the fiber.
3. Be sure not to pour the infill in large quantities on the synthetic turf. It is easier to work the fill in with smaller quantity sizes placed in the turf.
4. If the borders or edges are to be secured, save the infill installation for these areas for last.
5. Repeat the infill spread / fiber brooming process until the infill is evenly spread such that no more than three-fourths of an inch (¾") of grass fiber tips are exposed above the level of the infill. A good rule of thumb is two (2) to two and a half (2½) pounds per square foot.
6. Caution: Too much fiber exposed (not enough infill) will cause the fibers to mat or crush with heavy foot traffic. This will lead to premature wearing of the fiber and will void any manufacturer's warranty.
7. There may be more than one type of infill used on the same site. In many cases, a combination of silica sand and granulated rubber, or silica sand and manufactured sand top dressing, may be used in layers. In either case, the silica sand is installed first, followed by the granulated rubber or top dressing.
8. Be sure to follow the site specifications outlining the amount or depth of each infill material.
