Synthetic grass can be used in a wide variety of
applications and the installation techniques will vary depending on the
style of grass. There are a number of basic principles, however, which
should always be followed.
- In all cases it is essential to ensure that
the sub-base on which the synthetic grass is to be laid is of good
standard. Being a flexible product synthetic grass will reflect any
deficiencies in the sub-base. Bumps and lumps in the sub-base will
be repeated in the synthetic grass surface. Similarly “bird baths”
or “depressions” in the sub-base will allow water to pond on the
- The sub-base should be properly compacted and
adequately drained. For tennis courts and similar installations the
sub-base should have a slope of 1% in any one single plain. This can
be from side to side, front to rear or diagonal corner to diagonal
- Yarn dye batches can vary but unless advised
otherwise each roll of synthetic grass product when supplied as part
of a specific order will be of compatible dye batch. A coloured
stitch line on the right side of the roll identifies pile direction.
REQUIRED TOOLS FOR SYNTHETIC GRASS INSTALLATION:
- Tape measure
- Chalk line and Chalk
- Stanley knife
- Metal straight edge
- Notched trowel
- Carpet trolley
- Ashford Green synthetic grass adhesive
- Sand spreader/ Wheelbarrow
INSTALLATION CHECKLIST: BEFORE YOU START LAYING
- Check you have sufficient quantity of
synthetic grass, joining tape, adhesive, sand and rubber if required
- Your tools are cleaned and ready for work
- The base is adequately prepared
- The weather conditions are adequate (outdoor
SYNTHETIC GRASS INSTALLATION:
- As soon as possible after delivery, packing
bands around rolls should be released.
- Rolls are to be rolled out in their
approximate position and allowed 30 minutes to relax before cutting.
- Carpet and tape should not be adhered to base.
(Tensioning by stop nails is an advantage, providing nails are
removed from final court or landscaped area).
- Tape will be spread with adhesive to a minimum
width of 40cm.
- Seam joins should be slightly loose to avoid
peaking (undercut rather than over cut by no more than a stitch row
- All seaming joins should be “hand teased”
together, then rolled with a hand roller.
- It is recommended that only joining tape
supplied by Ashford Green Synthetic Lawn will be used.
- Edges for tennis courts will not be glued down
unless instructed otherwise, or at the junction of the courts if
there is more than one court involved.
- It is recommended that only Ashford Green
Synthetic Lawn adhesive be used.
- Adhesive will be spread in strict accordance
with Ashford Green’s instructions, which are printed on the drum
labels – the spread rates and trowel sizes must be adhered to:
Trowel size: 3.5mm x
3.5mm x 3.5mm V or square notch.
Coverage: 1 – 3 m2 per
- Be very careful to avoid getting adhesive on
the pile face. If adhesive does spill or come into contact with the
yarn, dissolve immediately with thinners. (mineral turpentine does
work, but not as well as thinners)
- Lay back carpet edges and place joining tape
evenly either side of join. Securing one end can help with
trowelling the adhesive and avoiding movement.
- For hard to hold carpet or when installing
over low absorbent substrates, it may be necessary to allow a short
tack up time of 10mins. However, roll back edges of carpet within 1
hour of applying adhesive.
- Lightly roll or tamp down carpet with feet to
ensure a firm bond. Do not allow traffic for 48 hrs.
- If using adhesive to stick carpet to a hard
subfloor, the subfloor must be clean, structurally sound, dry and
free from all contaminants which will inhibit good adhesion – this
includes polishes, paint, waterproofing membranes, concrete curing
agents and laitance. Deep indentations and cracks should be treated
with the appropriate cementitious screed in accordance with
APPLYING THE INFILL
- Other than basic sand filling techniques the
infill and fibrillation techniques are reasonably involved and need
to be discussed with Ashford Green installers.
- Sanding can be commenced after joint adhesive
has cured (other than in Tennis court application)
- The use of a suitable fertilizer spreader is
an excellent way of distributing kiln dried sand through the carpet
pile. Recommended depths and infill type vary depending on the
- Brooming sand with a stiff broom or powered
broom is recommended after Spreading.
* Notes on Tennis Court installation
- Roll out carpet piece and align to chalk
- Allow to relax.
- Commence sanding from center.
- Continue to sand out to 300mm-450mm from
- Cut and glue join.
- Sand joint immediately to avoid any seam
peaking, brushing along the grain, not across.
- On completion, sand will be topped up and
leveled out properly.
All lines are tufted in
with the exception of the service line, which should be laid (cut in)
last. Lines for service line from extra base and center lines.
On completion and before
the final sand, all joins should be checked.
NO JOINS SHOULD BE
VISIBLE by either a change in pile or too big a cut.
