Why Edging on Melamine Boards Matters (and How Water Affects It)

When choosing cabinetry or custom-built cupboards for kitchens, bathrooms, or offices, melamine boards are a popular and practical choice. They offer durability, a sleek finish, and a variety of colour options. But one detail that's often overlooked — yet incredibly important — is edging.

In this post, we’ll explore why edging matters and how exposure to water can affect unedged or poorly edged melamine boards.

What is Melamine?

Melamine boards are engineered wood panels (usually chipboard or MDF) coated with a hard resin-impregnated paper surface. This gives them a durable outer finish that is scratch-resistant, easy to clean, and comes in various colours and textures.

But while the top and bottom surfaces are sealed and protected, the sides (or edges) are raw and highly absorbent unless properly finished.

Why Edging is So Important

Edging is the thin strip of material (usually PVC, ABS, or melamine) that’s bonded to the edges of the board. Here’s why it’s critical:

1. Moisture Protection

• The biggest enemy of unsealed melamine edges is water.

• Bathrooms, kitchens, sculleries, and even office cleaners using a wet cloth can expose cupboards to moisture.

• Without edging, water seeps into the board, causing swelling, warping, or even delamination.

2. Durability

• Edging helps prevent chipping and splintering of the corners and edges.

• It protects the board during transport, installation, and daily use — especially in high-traffic areas.

3. Hygiene & Easy Cleaning

• Proper edging creates a sealed surface, leaving no room for dirt, bacteria, or mould to collect in raw areas.

4. Professional Appearance

• Edging gives cupboards and panels a clean, finished look.

• It improves the aesthetic of the joinery and adds value to your space.

  
  

 What Happens When Water Gets into Unedged Melamine?

Where we often use melamine in sculleries, kitchens, and bathrooms — water exposure is common. Here’s what to expect when moisture reaches unprotected edges:

• Swelling: The chipboard core absorbs water like a sponge and expands.

• Peeling or Bubbling: The surface may lift or bubble over time.

• Structural Weakness: Joints become compromised, and shelves or doors may sag or warp.

• Permanent Damage: Swollen board cannot return to its original shape and often needs to be replaced.

  
  

Once melamine absorbs water, it cannot be repaired — only replaced.

Quality Edging Makes a Difference

At BTM Joinery, we use high-quality edge-banding machines to ensure each panel is sealed properly on all sides. We also match the edging to your colour and thickness for a seamless, professional result.

Whether it’s a high-gloss kitchen, a utility cupboard in a garage, or a sleek office cabinet — we never compromise on the finish.
