The two tricks to a good artificial grass join can be found in the spacing and in the joining of two pieces.
- The spacing.
Looking at the back of the artificial grass, you can see the spacing between the stitches. When joining two pieces, you will want to create a space that is consistent with this spacing. To do this, it is recommended that you carefully cut the edge of one of the pieces to be joined close to the stitch, and the other away from the stitch, to help keep the space between the two pieces consistent with the rest of the turf. Butting the pieces up too close to each other may “mo-hawk” the grass blades, meaning the extra thickness of the blades along the join will create a visible inconsistent line, and an ever-visible join.
2. The Joining.
When you have positioned your two pieces of artificial grass at a proximity from one another that you are happy with, and having brushed up the join with your hand to check that they blend together well, you will want to use joining tape down the entire length of the join to make your join flat and permanent.
Mark the centre of the join (with a score in your cracker dust for example) at both ends so you know where to run the tape before flipping the edge of both pieces of grass out of the way. Use turf pegs or nails to secure your taught length of joining tape, adhesive side up, along the length of your join. You may wish to place additional pegs at intervals along the tape if it is a longer length and/or there is any wind.
Remove the paper backing of the tape, revealing the strong adhesive. Flip your pieces of grass back over and down onto your joining tape from one end to the other. Apply pressure along the length of the join to make sure it is bonded all the way along.
