Edge banding fails at the joint, the end and the water line, not on the face. Thickness, adhesive and colour matching decide whether the edge survives a wet kitchen. Use 1–2 mm banding and PUR adhesive in wet areas, match the colour within about 1 mm, and seal the ends and joints.
0.4–0.8 mm for dry areas, 1–2 mm for wet areas.
PUR adhesive for moisture and heat.
Match the face colour, not the batch number.
Seal the ends and joints.
The edge fails before the face.
1. Why edges fail
Edge banding covers the raw core of the board. It is thin, it takes the first impact, and it is where water enters. A band that lifts at the end or the joint lets water into the core, and the board swells. The face rarely fails first; the edge does.
2. Thickness by use
| Utilisez le | Grosor | Adhésif |
|---|---|---|
| Armoires sèches | 0.4 – 0.8 mm | EVA |
| Kitchen general | 1 mm | EVA ou PUR |
| Zones humides | 1 – 2 mm | PUR |
| Usage intensif | 2 mm | PUR |
| Bords visibles | 1 – 2 mm | PUR |
Thicker banding costs more but resists impact and moisture far better. In a wet area, the difference is not cosmetic.
3 Adhésif
EVA is the standard hot-melt and is adequate for dry areas. PUR is more moisture-resistant and handles heat better, which is why it is specified for wet areas and heavy use. The adhesive matters as much as the band thickness, and it is often the line that is cut first.
4. Colour matching
Match the band to the face under normal light, within about 1 mm. A visible line at the edge is the most common complaint, and it is usually a colour match issue, not a thickness issue. Keep a sample of the batch for later repairs.
5. Radius and profile
A softer radius at the edge resists impact better than a sharp square edge. On a door, the radius also affects how the edge catches light. The guide des finitions de portes covers how the edge interacts with the face finish.
6. Moisture and sealing
Seal the ends and joints, especially in wet areas. A band that is glued but not sealed at the end still lets water in. In a sink run, the cut-outs and the raw edges matter as much as the band.
7. Specifying edge banding
Name the thickness, the adhesive, the colour and the sealing requirement. A specification that says matching edge without a thickness is not checkable. The carcass guide covers the board the band protects.
8. Checking at inspection
Check three things: the band is adhered along the full length, the colour matches the face, and the ends are sealed. Run a fingernail along the edge; a lift is a failure even if it is small.
9. Une liste de vérification avant de s'engager
Avant de signer, veuillez confirmer six points : la qualité du circuit imprimé, le modèle de matériel, le système de finition, les normes d’emballage, le périmètre d’inspection et les modalités de paiement. Chaque point doit être confirmé par écrit, et non par téléphone. La liste de vérification du devis permet de synthétiser ces six éléments en un tableau comparatif d’une seule page.
10. Erreurs courantes
L'erreur la plus fréquente consiste à comparer le prix d'usine avec le coût final. La deuxième est d'omettre l'inspection du budget. La troisième est de payer le solde avant la validation de l'inspection. Chacune de ces erreurs est évitable grâce à un cahier des charges écrit et une inspection avant expédition.
11. Comment mesurer la pièce
Mesurez chaque mur en trois points : en haut, au milieu et en bas, et retenez la plus petite mesure. Les murs sont rarement d'équerre, et une courbure de 10 mm sur trois mètres modifie le remplissage. Mesurez le plafond à chaque angle et repérez les prises électriques, les radiateurs et les canalisations d'évacuation avant de dessiner. Un relevé précis est plus rapide qu'un dessin, et le guide de mesure est fourni avec une fiche imprimable.
13. Liste de contrôle des spécifications
Pour chaque matériau, indiquez quatre lignes : le nom du produit, sa nuance, son épaisseur et le traitement de surface ou de bord. Si le matériau est uniquement désigné par son nom, la nuance est laissée à l’appréciation du fabricant ; or, c’est la nuance qui détermine le coût et les performances.
14. Questions que l'usine posera
Attendez-vous à quatre questions : quelle nuance, quelle épaisseur, quel type de chant et de lot. Les réponses devraient déjà figurer dans le cahier des charges. Dans le cas contraire, l’usine choisira la solution la moins chère conforme au plan.
Foire aux questions
What thickness of edge banding should I use?
0.4–0.8 mm for dry areas and low-cost work; 1–2 mm for wet areas, heavy use and visible edges. Thicker banding resists impact better.
What is the difference between EVA and PUR adhesive?
EVA is the standard hot-melt and is fine for dry areas. PUR is more moisture-resistant and suits wet areas and higher heat.
Why does edge banding peel?
Usually because the edge was not clean, the adhesive was too cool, or the banding was too thin for the impact. Water and heat accelerate it.
How close should the colour match?
Within about 1 mm of the face colour under normal light. A visible line at the edge is the most common complaint.
Can edge banding be replaced?
Yes, a local repair is possible, but matching the colour and sheen after production is harder than matching at production.
Does edge banding affect compliance?
It affects moisture performance, which matters in wet areas. A thin band on an HMR board still leaves the core exposed if the joint is not sealed.
