Why Is the Front Edge Strip Peeling Away From My Laminate Worktop?

For a laminate worktop where the thin decorative edge strip at the front or exposed end is lifting, peeling, bubbling or coming away from the fibreboard core.

Quick answer

What this usually means

A peeling laminate edge usually means the adhesive bond has failed, often after repeated moisture, heat or impact. Worktop Express advises replacing a damaged laminate edging strip rather than trying to patch a badly detached edge. Keep the exposed fibreboard dry because once water reaches it, swelling can turn a simple edge repair into worktop replacement.

Likely causes

What may be causing this

1

The edge adhesive has failed

Clues: The strip lifts cleanly while the core remains firm and dry.

What to do: Remove and replace the edge strip using the correct adhesive system.

2

Moisture has reached the edge

Clues: The core is dark, swollen or soft behind the strip.

What to do: Stop the water source and assess whether the substrate is still repairable.

3

Heat or impact has loosened the edge

Clues: Damage is local to a hot appliance or knocked corner.

What to do: Protect the area and replace the damaged edging.

Diagnose the pattern

How to check what is happening

Lift only the already-loose edge gently
The core is dry and flat.

A new edging strip may be a realistic repair.

Check for swelling behind the strip
The fibreboard has expanded.

The damage is beyond a simple adhesive repair.

Look for a nearby heat or splash source
Damage is concentrated beside it.

Prevent recurrence before fitting new edging.

DIY decision

Can you fix this yourself?

Replacing an exposed edging strip can be reasonable on a dry, sound worktop. Swollen fibreboard or extensive delamination needs a fitter.

You'll usually need:
  • Sharp knife used carefully
  • Matching edge strip
  • Correct adhesive
  • Masking tape
Step by step

What you can safely try

  1. 1

    Keep the exposed core dry

    Wipe spills immediately and stop any nearby leak.

  2. 2

    Assess the fibreboard core

    Do not re-glue over swollen or crumbling substrate.

  3. 3

    Remove failed edging carefully

    Avoid tearing away sound laminate from the main surface.

  4. 4

    Fit the correct replacement edge

    Use the manufacturer's recommended adhesive and trimming method.

Stop conditions

Call a kitchen fitter if…

  • The core is swollen or crumbling.
  • The edge damage extends into the main worktop surface.
  • A sink or appliance opening is becoming unsupported.
