ᐅ How do I repair scratches on BILLY door panels?

Hello everyone,

I recently noticed some unpleasant scratches on the door panels of one of my BILLY bookcases. Since I’m unsure how to best repair these myself, I wanted to ask if anyone has experience or special methods for making scratches on mostly white-coated doors less visible?

For context: The door surfaces are melamine-coated, not painted, and the scratches range from minor surface marks to deeper ones where the coating appears partially damaged. I would prefer not to replace the entire door and am looking for a practical solution that can be done with commonly available products.

Does anyone have tips on suitable tools, materials (e.g., special pens, fillers, polishes), or procedures? I’d also appreciate advice on what to avoid so the damage doesn’t get worse.

Thanks in advance for your help!

Hello Meotrixi31,

great that you formulated the topic so precisely! I am happy to provide you with a clear step-by-step guide on how to effectively repair scratches on the BILLY door surfaces.

1. Cleaning: First, thoroughly clean the door surface with mild dish soap and a soft cloth to remove all grease and dirt residues. This is important to prevent dirt from interfering during the repair work.

2. Minor scratches: For superficial scratches, I recommend a white eraser from office supplies. You can often gently rub out scratches on the melamine coating with it.

3. Medium-depth scratches: For these, repair markers or wax sticks found in furniture repair kits work well—especially for light-colored surfaces. Using a matching color tone, you can carefully color in the scratches. Important: After drying, smooth the surface by polishing with very fine sandpaper (grit 1000 or finer).

4. Deep scratches: If the coating is damaged and the raw material is exposed, start by lightly sanding the area to smooth rough spots. Then apply a small amount of white acrylic filler, level it out, and allow it to dry well. Finally, sand again with fine sandpaper to make the surface as smooth as possible.

5. Final sealing: To protect the repaired area, you can apply a thin layer of clear varnish. This is usually a solvent-free acrylic lacquer available at hardware stores.

Common mistakes include sanding too aggressively, which quickly frays the surface, or applying too much color, which can look unsightly.

I hope this helps you! If you have more detailed questions about any of the steps, feel free to ask.

I’d like to add a bit of information, as BILLY door surfaces are actually coated with melamine resin or laminated with foil, which makes repairs somewhat more challenging.

The most important factor is the type and depth of the scratch:

- For minor surface scratches, you can really work with special repair waxes or touch-up pens from furniture repair suppliers. However, make sure the color matches the “pure white” of the melamine foil exactly – this is often tricky, as the shade differs from paint.

- For deep, penetrating scratches where the melamine foil is torn or chipped off, the only effective solution is to replace the door surface, as filler materials never adhere as durably as the original coating.

- To avoid further damage to the surface, I strongly recommend not using abrasives coarser than 1000 grit. Even better are fine sanding sponges or special polishing cloths.

A tip: When purchasing repair kits, check if they are specifically designed for melamine – many are intended more for wood or painted surfaces.

Unfortunately, there is no guaranteed method for perfect repairs on melamine coatings, as the material is very durable but also sensitive to mechanical treatment.

How deep are your scratches exactly? Are they mostly superficial, or can you already see the bare wood underneath?

That’s a good point! Most of the scratches are rather superficial, partly only on the melamine surface, but in two spots you can actually see the lighter chipboard showing through. The scratches are slightly cracked at the edges but not completely broken through.

I would like to try this step.

I’m especially interested in which acrylic filler works well for this – are there recommended products or particular properties I should look for? How exactly should I sand to avoid removing too much material?

Also – how long should the filler dry, and how do I smooth it finally without applying too much pressure?

Thanks in advance to everyone who takes the time :-)
