Why Proper Artificial Grass Joining Matters
Artificial grass is commonly supplied in rolls, meaning larger spaces often require two or more sections to be joined together. A properly installed seam should be secure, level and difficult to notice from normal viewing positions.
Correctly joining artificial grass helps achieve:
- A natural appearance: Neatly aligned edges help different turf sections blend together.
- Long-term durability: Suitable joining products help reduce unwanted seam movement.
- Better safety: Secure joins reduce the risk of raised edges becoming trip hazards.
- Consistent performance: Proper bonding helps the lawn withstand everyday use.
- Reduced maintenance: Well-installed joins are less likely to require early repairs.
- A professional finish: Matching fibre direction helps prevent obvious changes in colour or texture.
If you are installing an entire lawn, our artificial grass installation guide explains the wider installation process, including base preparation, laying and finishing synthetic turf.
Artificial Grass Joining Tape vs Adhesive
There are different ways to secure synthetic turf seams. The most suitable method depends on the type of grass, surface, project size and whether the installation is temporary or permanent.
Artificial Grass Joining Tape
Joining tape is positioned underneath two pieces of artificial grass to connect their backing materials.
Self-adhesive joining tape offers a convenient peel-and-stick solution that does not normally require separate glue.
Best suited to: Straightforward DIY projects and compatible permanent turf seams.
Artificial Grass Adhesive
Synthetic grass glue is designed to bond artificial turf to compatible surfaces or suitable joining materials.
It is commonly used for permanent installations, edge bonding and appropriate adhesive-and-seaming systems.
Best suited to: Applications requiring a strong adhesive bond, subject to product compatibility.
King Turf Tip: Self-adhesive joining tape and conventional seaming tape are not always interchangeable. Some products are designed to work independently, while others require a separate synthetic grass adhesive. Always check the manufacturer's instructions before installation.
What Is Artificial Grass Butyl Joining Tape?
Artificial grass butyl joining tape is a type of self-adhesive tape that uses a butyl-based bonding layer. It can provide a flexible, water-resistant connection when appropriately specified for synthetic turf.
However, not every self-adhesive artificial grass joining tape contains butyl. Product composition, bonding strength and surface compatibility vary between manufacturers.
If you are comparing butyl tape with other options, check the technical specifications and choose a product suitable for your turf backing and installation conditions.
King Turf offers commercial-grade artificial grass joining tape featuring a convenient peel-and-stick application.
Choosing the Right Joining Materials
Before purchasing installation accessories, consider the type of surface, the size of the project and the amount of traffic the lawn will receive.
| Joining Material | Main Purpose | What to Check |
|---|---|---|
| Self-Adhesive Joining Tape | Connecting compatible artificial grass sections without separate liquid glue. | Turf backing, surface preparation and outdoor suitability. |
| Butyl Joining Tape | Flexible pressure-sensitive bonding for suitable synthetic turf seams. | Butyl composition, compatibility and intended use. |
| Artificial Grass Adhesive | Bonding turf to suitable surfaces or compatible seaming materials. | Coverage, curing time, weather resistance and substrate. |
| Conventional Seaming Tape | Supporting turf joins when used with a compatible adhesive. | Required glue type, tape width and application instructions. |

How to Join Artificial Grass: Step-by-Step DIY Guide
Joining synthetic turf requires careful planning and accurate cutting. Follow these steps to create a secure seam and achieve a neat, natural-looking finish.
Step 1: Prepare the Base
Make sure the surface underneath your artificial grass is stable, level, clean and suitable for the intended installation.
For outdoor lawns, this generally involves preparing and compacting an appropriate aggregate base. Remove loose debris and correct uneven areas before positioning the turf.
Step 2: Position the Artificial Grass
Lay the artificial grass sections in their intended positions. Allow the rolls to settle according to the manufacturer's guidance before making final cuts.
Plan the layout to minimise unnecessary joins and reduce material wastage.
Step 3: Match the Pile Direction
Check that the grass fibres on both pieces lean in the same direction.
Different pile directions can reflect light differently, making a seam more noticeable even if the turf edges are perfectly aligned.
Stand back and inspect both sections from the main viewing area before cutting.
Step 4: Trim the Turf Edges
Using a sharp utility knife, carefully trim the backing of each turf section to create clean edges.
Cut from the backing side where practical to avoid damaging the grass fibres.
Bring both sections together and check that the backing edges meet neatly without overlapping or leaving large gaps.
Step 5: Position the Joining Tape
Fold back both turf edges and place the artificial grass joining tape centrally beneath the intended seam.
Keep the tape flat and straight to provide consistent contact with the turf backing.
For self-adhesive tape, follow the instructions for removing the protective liner and positioning each section.
Step 6: Apply Artificial Grass Adhesive if Required
If your joining system requires glue, apply the recommended amount of synthetic grass adhesive onto the compatible joining material or approved surface.
Spread it evenly according to the product instructions. Avoid excessive adhesive, which may squeeze through the seam and become trapped in the fibres.
Do not add liquid glue to self-adhesive joining tape unless its manufacturer specifically recommends doing so.
Step 7: Join the Turf Sections
Carefully lower the first section onto the joining material, followed by the second.
Align the edges gradually along the seam, ensuring there are no overlaps, trapped fibres or large gaps.
Avoid stretching the artificial grass to force the sections together.
Step 8: Apply Pressure and Allow the Bond to Set
Apply firm, even pressure using a method suitable for the tape or adhesive being used.
If liquid adhesive is involved, follow the manufacturer's curing requirements. Avoid foot traffic or movement until the bond is sufficiently secure.
Step 9: Brush and Inspect the Seam
Once the joining system has secured properly, gently brush the artificial grass fibres upright using a suitable turf broom.
Inspect the seam for raised backing, visible gaps and uneven fibres. Finish the remaining perimeter securing and grooming as required.
How to Avoid Visible Joins in Artificial Grass
One of the most common DIY concerns is how to make artificial grass joins less noticeable. Although complete invisibility cannot be guaranteed, careful installation can significantly improve the final appearance.
Match the Pile Direction
Always lay neighbouring sections with fibres facing the same way to reduce visible colour and texture differences.
Use Matching Turf
Where possible, join artificial grass from the same product and production batch to reduce differences in colour and pile height.
Cut Accurately
Use a sharp blade and carefully trim the backing. Uneven edges can create gaps or raised joins.
Avoid Overlapping
Keep the backing edges level and properly aligned. Overlapping can create a noticeable raised line.
Plan Seam Locations
Minimise the number of joins and, where practical, position them away from prominent viewing areas.
Brush the Fibres
After the seam has secured, brush the grass around it to help the fibres blend naturally.
Professional Tip: A well-prepared, level base is just as important as the tape or adhesive. Raised areas beneath a seam can remain visible even when the joining materials are applied correctly.
How Much Joining Tape and Artificial Grass Adhesive Do You Need?
Calculating materials before installation helps reduce waste and ensures you have enough products to complete every seam.
Calculating Artificial Grass Joining Tape
Measure the total length of all joins where separate pieces of artificial grass will meet.
For example:
- First seam: 4 metres
- Second seam: 6 metres
- Total seam length: 10 metres
For this project, you would need at least 10 metres of joining tape, plus a small allowance for trimming and adjustments.
King Turf's Artificial Grass Joining Tape comes in a 150mm x 15m roll, so one roll would be sufficient for this example.
Calculating Artificial Grass Adhesive
Adhesive requirements depend on the bonding area and the manufacturer's coverage instructions.
As a simple example, a 10-metre seam with a 150mm-wide application area has a bonding area of:
10m x 0.15m = 1.5m²
Compare this area with the adhesive's specified coverage rate and allow for any additional bonding required by the installation.
King Turf's 4L Synthetic Grass Glue lists approximately 16m² of coverage. Actual consumption depends on the substrate, application method and manufacturer instructions.
For larger projects, a 20L synthetic grass adhesive option is also available.
Common Artificial Grass Joining Mistakes to Avoid
Even small installation errors can affect how your artificial lawn looks and performs.
- Incorrect pile direction: Creates noticeable colour differences between adjoining sections.
- Uneven cutting: Leaves visible gaps or creates overlapping edges.
- Unsuitable adhesive: May fail to bond correctly or deteriorate under outdoor conditions.
- Too much glue: Can seep into grass fibres and leave visible hardened patches.
- Poor base preparation: May lead to raised joins, movement or uneven surfaces.
- Insufficient bonding pressure: Can reduce contact between the backing and joining material.
- Premature foot traffic: May disturb the join before the adhesive has properly cured.
- Unplanned turf layout: Can create unnecessary joins and additional material costs.
Taking extra care during preparation is generally easier than repairing a poorly installed seam later.
