Place your piece of tin flashing under the bottom roll that is being overlapped. The flashing will make for a solid and smooth cutting surface and cutting the seam will not disturb your smooth sub base.

Over lap the rolls about 2 inch the entire length at the seam so that the roll with the black strip still attached is on top.

Next, place bags of infill every 5 feet on both sides the length of the seam. The weight of the infill will not allow the rolls to move during the seaming process.

Starting at one end of the roll, cut the top overlapped roll of turf by following the edge of the bottom roll with your utility knife. Continue this process the full length of the seam. This technique will make for a perfect cut and seam.

Be sure to replace your utility knife blade after cutting eight to ten feet in length. The goal is to cut through the turf and not rip through it. After the seam has be cut, join the two pieces together to ensure a tight fit before gluing the rolls together.
