Can You Replace One Section of Artificial Grass?

Yes, a damaged section of artificial grass can sometimes be replaced without lifting the entire lawn. Success depends on securing a stable base, creating a neat join and finding the closest possible match. 

Even with careful preparation, the repair may remain visible if the replacement differs in colour, pile direction or age. Before cutting into the lawn, identify what caused the damage. In many cases, diagnosing the problem is just as important as completing the repair itself.

Start by Checking Whether the Damage Is Localised

A local repair works best when the damage is confined to one area and the surrounding grass, joins and base remain secure. Widespread movement or drainage problems usually require more than a replacement patch.

Check the following:

• Damaged fibres or backing

• Lifting seams or edges

• Soft spots beneath the surface

• Standing water

• Damage extending beneath edging or furniture

• The original cause of the problem

A small burn may suit a local repair, while several failed joins are better addressed before replacing any grass. If the issue is seam-related, first learn how to fix an artificial grass seam.

Surface Damage

Burns, cuts, tears, stains and local crushing may be suitable for repair. Flattened fibres can sometimes recover after brushing.

Underlying Installation Problems

Failed joins, an uneven base, poor drainage, loose edges and widespread movement should be corrected before replacing any section of grass.

Which Types of Damage Can Usually Be Patched?

Burns, cuts, tears and isolated contamination can usually be repaired if the surrounding grass and base remain in good condition.

Repairing a local defect will not resolve widespread installation problems or a failing base.

Decide Whether to Patch a Small Area or Replace a Larger Strip

A small patch uses less material, although it may create several visible joins. Replacing a larger strip to an existing edge or seam can sometimes produce a neater finish.

Choose the repair shape for the least noticeable result, not simply the smallest cut. If needed, first work out how much artificial grass you need before ordering replacement material.

Find the Closest Possible Match for the Existing Lawn

The best replacement is an offcut from the original installation or grass from the same product and production batch. Even then, new grass may still look different after installation.

Check your original order details or ask the installer if any spare material was retained. Compare pile height, density, blade shape, colour blend, backing and pile direction. View samples outdoors from your usual viewing position rather than relying on online images or pile height alone.

Why the Same Product May Still Look Different

Weathering, brushing, sand infill and normal use change how artificial grass looks over time. Production batches can also vary, so an exact match cannot be guaranteed. New fibres may blend more naturally after settling and regular brushing.

Check the Pile Direction Before Cutting

Match the pile direction with the existing lawn and mark it on the backing before cutting. Rotating an offcut to make it fit can make the repair far more noticeable.

Gather the Correct Tools and Joining Materials

A successful repair requires suitable tools and compatible joining materials. Always follow the manufacturer's guidance for any tape or adhesive.

You'll normally need:

• Replacement artificial grass

• Sharp utility knife

• Straight edge and tape measure

• Joining tape

• Compatible outdoor adhesive

• Artificial grass brush

• Sand infill, where required

• Weights or boards during curing

A sharp blade produces cleaner cuts and neater joins. Choose joining products designed for artificial grass, and check manufacturer instructions for compatibility, application and curing before starting the repair.

Remove the Damaged Section Without Harming the Surrounding Grass

Remove only the planned repair area. Straight, controlled cuts create neater joins and reduce the risk of damaging surrounding fibres.

1. Mark the repair boundaries.

2. Cut through the backing using several controlled passes.

3. Lift the damaged section carefully.

4. Remove any failed tape or adhesive.

5. Inspect the exposed base.

Inspect the Base Beneath the Repair

Before fitting the replacement, check the base is firm, level and free from debris. Confirm drainage remains effective and repair any dips or movement before continuing. A stable base is essential for a secure, long-lasting repair.

Cut and Position the Replacement Piece

Cut the replacement slightly oversized, align the pile direction and trim gradually until the edges meet neatly without overlapping or leaving excessive gaps.

Dry-fit the replacement before preparing the join.

• Check the pile direction.

• Position the piece from the main viewing angle.

• Cut from the backing.

• Trim in small stages.

• Ensure the fibres remain clear of the edges.

• Confirm the replacement sits level with the surrounding lawn.

Resist the temptation to make one final cut immediately. Several small adjustments produce a more accurate fit than removing too much material in one pass.

Join the New Section to the Existing Artificial Grass

The replacement should be joined using materials designed for artificial grass, ensuring both backing edges are fully supported. Follow the manufacturer's instructions for any joining products.

1. Fold back the surrounding edges.

2. Position joining tape beneath the seam.

3. Apply compatible adhesive as directed.

4. Bring the backing edges together without overlap.

5. Keep fibres clear of the seam.

6. Protect the repair until fully cured.

Reapply Sand Infill Where Required

If your lawn uses sand infill, replace the specified amount and brush it evenly through the fibres. Avoid using infill to disguise a poorly aligned seam.

Make the Repair Less Noticeable

Correct pile direction, close seam alignment and careful brushing can reduce the visual difference, although they cannot guarantee an invisible repair.

Use this finishing checklist:

• Brush surrounding and replacement fibres in the same direction. Learn how to brush artificial grass correctly for the best results.

• Remove trapped fibres from the seam.

• Replace sand infill where required.

• Allow new fibres to settle naturally.

• Check the repair from normal viewing positions.

• Avoid disturbing the join once the adhesive has cured.

Why Might the Replacement Section Look Different?

A replacement piece may appear different because it is newer, more upright or supplied from another production batch. Weathering, brushing and normal use also influence how artificial grass looks over time.

Matching should consider blade shape, density, backing and pile direction, not colour alone.

When Is Replacing the Whole Artificial Lawn Better?

Replacing the entire lawn is usually the better choice when damage extends beyond one localised area, the base has failed or a suitable replacement cannot be sourced.

Consider full replacement if you have:

• Multiple damaged sections

• Several failed seams

• Widespread fading

• Persistent drainage problems

• An uneven or unstable base

• Loose edges across the lawn

• Grass that is no longer available

• Repair costs approaching replacement costs

• High expectations for a consistent appearance

Replacing one damaged section will not resolve poor installation or widespread structural issues. Taking time to compare repair and replacement options leads to a more informed long-term decision.

Prevent Similar Damage in Future

Preventing future damage starts with understanding what caused the original problem.

Helpful steps include:

• Keep barbecues and fire pits away from artificial grass.

• Fit protective feet to heavy furniture.

• Avoid dragging sharp objects across the surface.

• Repair loose edges promptly to help stop artificial grass edges lifting.

• Follow appropriate cleaning guidance.

• Check drainage after heavy rainfall.

• Store labelled offcuts from the original installation.

• Keep your product details and order information.

• Inspect joins regularly.

• Check product compatibility before using cleaning chemicals.

Keeping an original offcut can make future repairs far easier to match than sourcing replacement grass years later.

Frequently Asked Questions About Replacing Artificial Grass Sections

Can you patch artificial grass without joining tape?

Use joining products made for artificial grass to help create a secure repair.

Can you use a different artificial grass product?

Yes, although differences in colour, pile and backing may remain visible.

Will a patched section affect drainage?

Not if the repair, base and joining materials are suitable.

How long does a repair take to set?

Follow the adhesive manufacturer's curing instructions.

Can you repair artificial grass damaged by a pet?

Cleaning may resolve minor issues. Damaged fibres or backing may need replacing.

Should you repair it yourself or use an installer?

DIY suits straightforward repairs. Seek professional help for drainage, failed seams or uncertain product matching.

Replacing one section of artificial grass can be a practical solution when the damage is contained, the base remains stable and a close match is available. 

Before cutting, identify the cause, confirm the pile direction and decide whether a larger replacement strip would create fewer visible joins. If you're unsure about matching products or the condition of the base, ask Tuda Grass for advice before ordering replacement materials or starting the repair.
