How to Stop Artificial Grass Edges Curling Up

Artificial grass edges usually curl when perimeter fixings, adhesive, edging or the supporting base stop holding the backing flat. Keep people and pets away from a raised section first, then inspect the backing and perimeter support before adding adhesive or new fixings.

Finding the cause matters. Covering a loose edge without checking what sits underneath can leave the original fault unresolved and create another repair later.

Why Do Artificial Grass Edges Curl Up?

Edges curl when the backing loses secure contact with the perimeter. Loose fixings, failed adhesive, damaged edging, settlement, debris or movement beneath the grass can all contribute.

The visible curl may be a symptom rather than the whole problem.

Is It Edge Lifting or a Seam Opening?

Edge lifting affects the outer perimeter, while seam separation occurs where two pieces of grass meet. Each needs a different repair approach.

Is the Backing Still Flexible and Undamaged?

Inspect the backing for tears, cracks or permanent creases. Intact backing may be suitable for refitting, while badly damaged sections may require replacement.

Is the Curled Edge a Minor Repair or a Wider Problem?

A small isolated lift with firm support and intact backing may be suitable for local repair. Several lifting areas, recurring movement or a soft base suggest a wider installation issue.

Photograph the affected area before disturbing it. This gives Tuda Grass or your installer useful information if further advice is needed.

Make the Lifted Edge Safe Before Repairing It

Restrict access to a raised edge until it has been secured, particularly near doors, paths or areas used by children, pets and older people.

Move furniture, toys and pet bowls away from the area. Avoid improvised screws, pins or coverings which could introduce another hazard.

If the installation is recent, check any installer guarantee before carrying out repair work. Photograph the fault first and identify where movement starts and ends.

Check the Edging and Base Before Adding New Fixings

New fixings only work if the edging and base remain stable. Check the perimeter for movement, damage or deterioration, then inspect beneath the lifted edge for loose material, hollows, water or pet disturbance before carrying out repairs. If you're unsure how the original base was constructed, see our guide on how to install artificial grass. 

What If the Base Is Soft or Wet?

Investigate the cause before adding fixings or adhesive. Ongoing movement may need professional assessment.

What If Pets Have Dug Near the Edge?

Restore the base first, then check the edging still provides secure support.

Secure the Edge With the Correct Fixing System

Use a fixing system compatible with the artificial grass backing, perimeter edging and supporting base. Identify the original installation method before carrying out repairs, as different surfaces may require different approved fixings.

Should You Add More Pins or Nails?

Only if the edging and base remain stable. Extra fixings will not solve movement beneath the grass.

Can You Secure an Edge With Adhesive and Fixings?

Some systems combine both. Check compatibility first and avoid blocking drainage or trapping the pile.

Repair the Edging System Before Refitting the Grass

If the edging moves, has deteriorated or no longer holds the grass in position, repair the restraint before securing the backing again.

Inspect the full affected run rather than only the most visible corner. Look for rot, cracking, corrosion, movement and alignment problems.

Keep drainage routes clear and ensure repaired edging works with the intended fixing method. A neat perimeter depends on stable support as well as accurate cutting.

Cut the Artificial Grass Edge Accurately

The edge should meet the perimeter without being stretched or forced into place. Only trim once the grass is correctly positioned, using a sharp, suitable knife and controlled cuts. Avoid removing more material from an already short edge, as this may prevent a secure repair.

Should You Trim a Curled Edge Before Refitting It?

Do not trim purely because an edge has curled. First check whether the backing can still lie flat and reach the restraint. Permanently damaged sections may require replacement rather than further cutting.

Apply Artificial Grass Adhesive Correctly

Use only an exterior adhesive approved for the artificial grass backing and supporting surface. Prepare the area according to the manufacturer's instructions, keeping it clean, stable and free from loose debris or standing water. Follow all application, curing and safety guidance.

How Long Should the Repaired Edge Be Left Alone?

There is no universal curing time. Leave the repaired edge untouched for the period stated by the adhesive manufacturer, and keep children, pets and furniture away until the adhesive has fully cured.

Allow the Grass to Relax Before Final Installation

For new installations, artificial grass should be positioned and allowed to relax in line with product instructions before final cutting and fixing.

This helps reduce roll tension before the perimeter is secured. Keep pile direction consistent and avoid stretching the material towards an edge.

Relaxation is mainly a prevention measure. It should not be treated as a guaranteed way to correct old, creased or damaged backing.

Keep Edges Clear of Weeds, Soil and Debris

Clear leaves, loose soil, weeds and garden debris from the perimeter to keep the edge visible and make developing movement easier to spot.

Pay particular attention beside flower beds, raised planters and plant pots. Soil can work beneath an already loose edge and obstruct inspection.

Avoid repeatedly lifting the grass for cleaning. Check perimeter areas after heavy gardening work or periods of wet weather.

Avoid Pulling or Repeatedly Lifting the Grass

Repeatedly lifting an edge can stretch or crease the backing and weaken the existing fixing point.

Avoid dragging furniture across the perimeter or pulling the grass towards a restraint. Where drains or inspection covers need regular access, plan access carefully rather than repeatedly peeling back an unsecured edge.

Frequently used routes beside paths and doorways deserve regular checks for early movement.

How Do You Repair a Curled Artificial Grass Edge?

A repair should address the underlying fault before the backing is secured again.

1. Restrict access.

2. Photograph the area.

3. Identify the base and fixing system.

4. Lift only the necessary section.

5. Inspect the backing.

6. Remove loose debris.

7. Repair unstable edging or base material.

8. Check the grass still reaches the perimeter.

9. Use an approved fixing or adhesive system.

10. Realign the edge and pile.

11. Follow curing instructions where adhesive is used.

12. Check for movement before normal use resumes.

If you're unsure which repair method is suitable or discover damaged backing, contact Tuda Grass for product-specific guidance before continuing.

When Should a Damaged Edge Be Replaced?

Replacement may be the better option if the backing is torn, permanently creased or cut too short to reach the perimeter. Matching an existing lawn also requires consideration of pile direction, weathering and product availability. 

If a replacement is needed, explore the artificial grass range to find the closest match before planning a repair.

When Should You Ask a Professional for Help?

Seek professional advice when several edges are lifting, the base is soft or wet, edging has failed across a longer section or previous repairs keep moving.

Support is also sensible where the grass is fully bonded to a hard surface, a seam is opening nearby or damaged backing needs matching and joining.

When you contact Tuda Grass, include photographs, the product name if known, installation date, base type, edging material, affected area and details of previous repairs.

Frequently Asked Questions About Curling Artificial Grass Edges

Can You Glue a Curled Artificial Grass Edge Down?

Yes, if the backing, base and surface are suitable, and you use an approved exterior adhesive. Do not bond over damp or loose material.

Why Does the Same Edge Keep Lifting?

Repeated lifting usually points to an unresolved issue, such as movement in the base, failed edging or damaged backing.

Can You Use Carpet Adhesive?

No. Choose an adhesive approved for exterior artificial grass and the supporting surface.

Can Heat Flatten a Curled Edge?

Do not use heat guns or boiling water, as these can damage the fibres, backing or adhesive.

Can Pets Cause Edges to Lift?

Digging or repeated activity can loosen an already vulnerable edge, although the base and fixing system should also be checked.

Is a Lifted Edge Covered by a Warranty?

It depends on the product, installer and warranty terms. Check your documentation and contact the original installer before carrying out repairs.

Can You Replace Only the Damaged Edge?

Sometimes. Product matching, pile direction and the condition of the surrounding lawn all influence whether a partial replacement is practical.

A raised artificial grass perimeter needs more than a cosmetic fix. Make the area safe, identify why it has moved and inspect the backing, edging and base before choosing a repair.

Use a fixing or adhesive system suited to the actual installation. Where the backing is damaged, the base keeps moving or repairs repeatedly fail, professional assessment can prevent further work being carried out on an unresolved fault.
