(Over Concrete, Putting Greens and Rooftops)
Artificial Turf Over Concrete
- Be sure the surface is clean, smooth, and free of debris.
- Next, align turf pieces (if more than one) to cover area prepared to be installed.
- Trim salvage edge of one piece of turf (if seaming multiple rolls). This can be done by folding over the edge to expose the back of the turf.
- Depending on turf type, you can follow a stitched row for a straight cut.
- If a secondary backing is present (foam or felt backing), pull edge of turf to center of itself and lay it flat. At this time, a chalk line may be used to make a straight cutting line on the back of the turf.
- Your goal is to make this first cut STRAIGHT.
- Adhere the turf to a concrete surface (recommended to glue entire surface down). Next best thing is to glue down around perimeter (18″ wide strip of adhesive).
- Nailer boards can also be anchored to the ground. The turf will be stapled to the nailer board (staple ever 6″-12″ around perimeter). This comes in hand when turf may be removed and re-installed in a different location or defacing the concrete is not an option.
Seaming The Turf
- Fold back two pieces of turf that will be seamed. Fold back at least 18″ each to expose concrete below.
- Position seaming tape in center of seam under turf.
- Apply adhesive to the seaming tape using a notched trowel (1/8″ notched trowel) to evenly and carefully spread adhesive.
- Leave approximately 1/2″ on each edge of tape unglued to avoid gluing sub-base material to back of turf.
- If directly gluing to concrete, first glue seaming tape to concrete. After gluing seaming tap to concrete, then repeat process on adhering turf to tape.
- On some products you may be required to close the seam at the same time with both rolls in order to effectively make a nice seam (putting green material).
- Adhesive must be completely set before additional stress is placed on the surface.
Installing Sleeves, Cups and Flags For Putting Greens
- Once base is prepared and compacted (for crush stone only) holes should be dug.
- For concrete surfaces, holes should be formed before concrete is poured. Add sleeves after concrete cures. Cups and flags will be added after putting green is installed.
Rooftop Installs (Suggestions Only)
*As we are not roofers, we cannot recommend installation procedures on all rooftop applications. The notes and guidelines below are simply suggestions from installers on previous rooftop installations. BE CAREFUL NOT TO PUNCTURE ROOFING MATERIAL.
- No nails or screws are to be used unless a nailer board has been installed around the perimeter, by others.
- Seaming layout should be done, keeping in mind that small length rolls are easier to handle (most rooftops do not have access and elevator shafts that can handle full size rolls of turf).
- Once again, roll out turf and trim salvage edges for seaming.
- Align rolls keeping turf fiber direction the same.
- See previous steps on adhering rolls of turf to seaming tape (be sure to leave at least 3/4″ around seaming tape edge so adhesive will not stick to turf and roof material).
- Rooftop terraces do not require and are not suggested to have infill. This is due to keeping less weight on roof structure.
- TurfOutlet.com makes no guarantee as to weight bearing capacity of existing work areas. Consult with a local engineering firm, contractor, or roofing supplier.
