Seaming Basics — Premium Grass Blades
Seaming Basics
When installing artificial turf, creating seamless joins between sections of grass is crucial for both aesthetics and durability. These joins, known as seams, come in two main types — and getting them right can make the difference between a seamless look and a visible flaw.

Weighing Your Options
Advantages & Limitations
Head Seams
Grain-Perpendicular Seams
Head seams occur where two ends of turf rolls meet, running perpendicular to the stitch rows.
These seams are structurally sound but visually sensitive and should be used sparingly and only when necessary (e.g., managing offcuts or transitioning in tight spaces).
Side Seams
The Standard Method
Side seams are the standard method for joining two rolls of turf laid out side-by-side, running parallel to the stitch rows (grain) of the turf.
These seams typically stretch across the longer axis of the installation area.
How to Seam Artificial Turf
The 6-Step Seaming Process
01
Align the Turf Edges
- Lay the turf sections side by side, ensuring the blades lean in the same direction for a seamless appearance.
- To marry the seam, trim the edges at least three stitch rows to create clean, straight lines for better bonding.
02
Position Seam Tape
- Place seam tape centered underneath where the turf edges meet.
- Ensure the adhesive side faces up and runs the entire seam length. Use spikes if needed to secure the seaming tape in place temporarily. Before moving on, ensure the turf has not moved, and the seam is still optimal.
03
Remove the Adhesive Backing
- Carefully peel off the protective backing to expose the adhesive surface.
- Work in small sections to prevent premature sticking.
- Keep the turf slightly lifted while peeling to avoid debris or dust sticking to the adhesive.
04
Join the Turf Sections
- Carefully align the turf edges and press them firmly onto the adhesive. For best results, use 2–4 people and maintain an even gap throughout the process. Smooth the seam by hand to eliminate gaps.
- Follow the standard seaming process using the zipper method for a tight and secure seam.
05
Secure the Seam
- Place nails every 6 inches and 2 inches from the seam along the seam to provide additional reinforcement.
- Drive nails in at a slight angle to anchor the turf securely without pulling the fibres down.
06
Weigh Down the Seam
- Place weight along the seam to ensure a secure bond. The best method is to use 2×6 planks weighed down with sandbags for at least 24 hours.
- Remove or hammer down the temporary nails holding the turf in place.

Tips and Tricks for Perfect Seams
Work in Warm Weather
Turf is more pliable in warmer conditions, making seams easier to align and secure.
Use a Chalk Line
Mark a straight line where the turf edges will meet for precise alignment.
Minimize Head Seams
Avoid head seams (end-to-end joins) whenever possible, as they are harder to conceal. Side seams (lengthwise joins) are easier to blend.
Inspect Blade Direction & Best Practices
-
Check the Pile Direction: Ensure all turf sections have blades leaning in the same direction to avoid visible seams.
-
Use Weight for Drying: Place weights (e.g., sandbags) along the seam while the adhesive cures for a stronger bond.
-
Leave a Gap for Expansion: Leave a small gap between turf sections to allow for expansion and contraction in extreme temperatures.
-
Always Use a Sharp Utility Knife: This ensures clean cuts without fraying the backing.
-
Take Your Time to Make Precise Cuts: Rushing can result in uneven seams.
-
Inspect the Blades After Marrying the Seams: Ensure they are upright and uniformly aligned.
What Not To Do
-
Don't Rush the Adhesive Application: Ensure the adhesive on the pre-applied seam tape is evenly pressed along the edges.
-
Avoid Visible Gaps: Misaligned edges or uneven trimming create noticeable gaps in the seam.
-
Don't Skip the Seam Roller: Misaligned edges or uneven trimming create noticeable gaps in the seam.
-
Don't Overstretch the Turf: Pulling the turf too tightly can cause seams to separate over time.
-
Avoid Heavy Traffic on Fresh Seams: Allow adhesive to cure fully before walking or placing weight on the seams.
Key Guidelines for a Flawless Finish
The Difference Between Seamless and Visible
The most crucial step is to follow our seaming guidelines carefully — these simple techniques can make the difference between a seamless look and a visible flaw. The diagrams illustrate the most common seaming mistakes. By following our recommended approach, you’ll achieve clean, nearly invisible seams once your installation is complete. Note that the outer three rows of turf blades on each edge tend to lean outward.TO ENSURE THE BEST RESULTS:
- Trim off the outer three turf blade rows before beginning your seam.
- Leave a 3/8″ gap between the pieces. Too little space can create a noticeable "mohawk" effect along the seam, while too much space can result in a visible "valley."
