7. Seaming Two Rolls of Turf
Omit this step if you are installing a
green 12 or 15 ft. wide.
 For
Polypropylene Turfs : On a hard surface, other
than your sub-base, lay the two rolls of turf side by side,
green side up to determine where you want them joined. Make
sure the "grain" from each roll of putting turf is
going the same direction. Once you have determined the
location of the seam, flip each roll over so the back side
is up. Use a knife with a brand new blade and cut between
the first and second row of stitching of the turf. Do this
slowly to avoid cutting any stitching so that the cut will
create a straight line for a tight fit.
For Nylon Foam Backed Turfs: Do not cut a
straight line in a turf with a foam backing for seaming,
because you cannot see the rows of stitching. If you
want to seam sections together yourself, ask us to cut the
sections at the factory so that the seams will fit together
correctly or employ a professional carpet layer. It is
easy to round off the corners or make it a kidney shape.
However, we recommend that you do not make a straight
cut yourself.
Flip the golf putting green back over so that the green is
facing up. Make sure the seam fits cleanly together and is
tight for the full length of the seam. Once you are
satisfied with the seam, move the pieces of turf to your
sub-base.
Position the pieces of turf to be seamed on the sub-base.
Place the two pieces of turf together to form a tight seam.
Position the seaming strip on the sub-base under the
seam. Make sure there is an equal amount of seaming
strip on each side of the seam. Pour the adhesive into
a smaller container and let set 5 minutes before applying.
Spread the adhesive over the entire area of the seaming
strip. If you use an adhesive from a calking gun,
spread it out in a spider-web format. The thickness of
the adhesive should not exceed 1/8".
Starting at one end of the artificial putting green, fold the pieces of turf
back together. Press the seam in place as you
go, applying pressure for good contact. After the entire
seam has been placed together, walk over the joined area
several times. Try not to walk directly on the seam. The
adhesive should appear in the seam, but be careful not to
allow adhesive to seep through the seam. Allow at least one
hour of cure time before finishing the installation process.
