Delamination of a kitchen worktop edge is one of the most common worktop problems in the UK — the thin decorative layer of the worktop peels away from the substrate underneath, usually starting at the edge or a joint. On laminate worktops, this manifests as the top layer (or the edging strip) lifting and curling. On post-formed worktops, it’s often the radius edge that starts to lift.
Why Does Worktop Delamination Happen?
- Water damage — the most common cause; water penetrating the edge of a laminate worktop (particularly around the sink) breaks down the adhesive bond between the laminate skin and the chipboard or MDF substrate
- Impact — a sharp knock to a worktop edge can crack the bond and start delamination
- Age and UV — older laminate worktops may delaminate simply from age, particularly in sunny kitchens where UV exposure has affected the adhesive
- Poor original installation — inadequate adhesive or poor edge sealing during fitting can lead to early delamination
Can Delamination Be Repaired?
In many cases, yes. If the delamination is caught early — before the substrate has absorbed significant moisture and swelled — the lifted section can often be re-adhered using appropriate contact adhesive or expanding PU adhesive, clamped, and finished. The result is often invisible or nearly invisible.
If the substrate (chipboard or MDF) has already swelled significantly from water damage, repair becomes more difficult. Swelled substrate changes the geometry of the worktop and the surface will not lie flat even if re-adhered. In this case, section replacement or full worktop replacement may be necessary.
Edge Strip Repairs
If the edging strip on a worktop has lifted or come away, this is almost always repairable — the original strip can often be re-bonded, or a replacement matching strip sourced and fitted. Edging strip repair is straightforward and inexpensive.
