Here
is the information on gluing down the tee mats. It was sent to me by one
of our customers who, as I mentioned to you, is in the business of
installation of back yard putting greens using their own high pile
turf. You will note references to backer board as he need something
to elevate the height of the tee mats since they are only 1/4"
thick. Here it is:
1. Because the putting green turf we use is
taller than most, we had to find a way to raise the tee mats about 1/4" to
be flush to the surface.
2. We used Hardi-backer as a base for the mat - conveniently, the backer board is scored with 1" markings making it easier
to make a matching base.
3. I then marked the holes in the mat on to the
backer-board and "hinged" over the mat exposing the two surfaces to be
mated together.
4. I brushed on the DAP Weldwood contact cement
(brush included) around the edge and added two strips between the holes for
added grip. I paid very close attention to the corners because that is
usually where we had problems in the past. Contact cement takes a few
minutes to set up before you put the two parts together, so I had plenty of
time to apply the glue to both the top of the backer board and the tee mat
back. After letting them sit for just a couple more minutes I carefully
flipped the mat over and mated the two. Contact cement grabs quickly and
does not allow much movement once put together. If I were going to do
this a lot I'd create a jig that would hold both pieces inside a frame to
insure correct placement. Final step was to use carpet adhesive to put
the final assembly on concrete.
(Additional comments) It could be that mounting the mats
to a thin piece of stiff material might be the key. In the past, the
problem was always that the mat would not adhere directly to the
concrete. Maybe being adhered to an intermediate product and then
to the concrete will solve the problem.
Because, as I mentioned, this has always been an
open question, I can't give you any guarantees as to whether this will
work. I do think, rather strongly, that the adhesive is an extremely
important component to the success or failure in this project.
