Step 1 – Position the Artificial Grass Rolls
Roll out both artificial grass pieces onto the prepared sub-base and position them exactly where the join will occur.
Allow the two grass rolls to overlap by approximately 100mm where the join will be made. This overlap allows the edges of both rolls to be trimmed accurately to create a straight and clean seam.
Step 2
Fold back both artificial grass rolls and carefully trim approximately 4 stitches (around 50mm) from each roll using a sharp Stanley knife.
Cut through the backing material as close to the grass seam as possible. Trimming both edges ensures the two pieces of artificial grass fit neatly together when positioned back into place.
Take care to cut the full length of both rolls so the join remains straight and consistent
Step 3 – Position the Join Correctly
After trimming the edges, carefully position both grass rolls back into place.
Leave a small 3mm gap between the backing of the two artificial grass pieces. This small gap allows the grass fibres to sit naturally without creating a visible ridge or seam.
Important Joining Tip:
- If the rolls are pushed too tightly together, a white visible line or 'Mohawk effect' may appear along the join.
- If the gap is too wide, the grass fibres may separate and reveal a dip in the pile which will create a white visible line or 'Valley effect.
Step 4 – Apply Joint Tape and Adhesive
Once the positioning is correct, fold both rolls back again and place a length of artificial grass joint tape along the full length of the join.
The most fibrous side of the tape should face upward (The adhesive side) with the smooth green side facing the ground.
Apply a thin layer of artificial grass joint adhesive to the tape using a zig-zag pattern. Ensure the adhesive is spread evenly along the entire seam to create a strong bond.
Step 5 – Secure the Artificial Grass Join
Carefully fold both grass rolls back down onto the adhesive tape, ensuring no grass blades become trapped beneath the join.
Press firmly along the entire seam to create a secure bond. Artificial grass securing U-pins can also be installed along the length of the join if required.
To ensure a strong seal, place a timber batten or weight along the seam and allow the adhesive to cure for a few hours.
Once set, brush the grass fibres using a stiff broom or power brush to blend the fibres together and create a natural finish.
