ᐅ Working with Billy Regal Wood – Tips for Finishing and Touch-Ups

Hello everyone, I am planning to refinish a wooden Billy shelf to repair small scratches and uneven coloring. I am especially interested in the correct process for working with wood, for example, how to best remove scratches or small dents without causing further damage to the surface. Additionally, I would like to know which tools and abrasives are most suitable and how to renew the paint or finish to achieve a durable and even result. Are there any specific tips for refinishing the typical MDF boards used for Billy shelves? Thanks for your help!

Hello Zarfar, I think your question is well structured! For Billy shelves, it’s important to note that they are usually made from particleboard or MDF panels coated with a thin layer of melamine or lacquer. Small scratches or dents can best be initially treated gently with fine sandpaper (grit 320-400), but be careful not to remove too much material.

For touch-ups, I always recommend the following steps: first, sand gently, then repair the spots using a color-matched touch-up pen or lacquer pen. If the lacquer is peeling or heavily damaged, repainting with a matte acrylic lacquer can help. It’s important to apply thin layers and allow them to dry thoroughly.

Tools like soft sanding sponges or sanding blocks can help achieve a more even surface. Avoid aggressive abrasives that could damage the thin coating. 🙂

That’s a good approach, but I’d like to add some details that are important for achieving a perfect result. First, you should carefully inspect the Billy shelf: Where are the damages particularly deep? Are they really just scratches, or are there also slight dents in the surface?

For scratches, a wet sanding with very fine sandpaper (grit 400–600) is often sufficient. The sandpaper should always be used along the grain, even if the coating is melamine foil—this helps avoid dull spots or uneven sanding marks.

For deeper dents, you can apply wood filler that adheres well to the surface and can be smoothed out with a putty knife. After drying, fine sanding is essential to ensure the transitions to the rest of the surface are not visible.

For painting, I recommend acrylic or water-based clear lacquer, as these work better with melamine surfaces and do not darken over time. Important: apply very thin coats and allow at least 2–3 hours of drying time between each layer.

One more question: Do you plan to use the shelf heavily later on, or is it mainly for aesthetic improvement? This could influence your choice of finish.

As an addition: MDF or particle board shelves like those in the Billy bookcase are generally sensitive to moisture, which you should keep in mind during all sanding and painting work. It can be helpful to treat the surface with a special primer designed for wood-based materials before the actual painting, as this ensures better adhesion of the topcoat.

I agree with that; acrylic paint is ideal because of its flexibility and durability. It is also important not to apply a coat that is too thick to avoid runs. For the right tool choice, I recommend a high-quality fan brush or a small foam roller to achieve an even finish.

If you only want to visually conceal scratches without sanding, there are also so-called "furniture repair markers" that can be applied quickly and represent an acceptable everyday solution.

Interesting, but I’d like to question this briefly: Is it really effective to just cover a damaged melamine surface with paint? Melamine is basically a hard, wear-resistant coating – once it’s damaged, paint may not adhere well to the underlying board.

I would rather recommend completely stripping the damaged areas on Billy shelves or sanding them extensively, then applying a primer before repainting. Otherwise, there is a risk that the new paint will peel off again or apply unevenly.

Also, for worktops or heavily used surfaces, it’s worth considering replacing the panel or fully covering it with self-adhesive foil – simply touching up with paint is often only a temporary solution, especially with MDF-based products.

What do you think? Has anyone had long-term experience with just repainting Billy shelves?
