ᐅ Placing a BILLY bookshelf made of wood – how to avoid splintered edges?

Hello everyone,

I recently bought the Billy shelf from IKEA and would like to assemble it using wood. However, I have a common problem: the edges, especially where the boards are joined or where the shelves rest, often chip easily.

My question is: how can I set up the BILLY shelf made of wood without the edges chipping during assembly or when placing the shelves? Are there specific techniques, preparation steps, or tools that can prevent this? I want to avoid having broken spots or rough edges after just a few days, as the wood seems quite sensitive.

Thanks for your tips!

To avoid splitting edges, I recommend the following steps:

1. Carefully prepare the edges by lightly sanding them with fine-grit sandpaper (220 grit or finer). This smooths out any irregularities that could cause splitting during assembly.

2. Use assembly aids such as felt pads or thin sealing tape at contact points to reduce mechanical stress on the edges.

3. When assembling, make sure to pre-drill and countersink holes for screws or dowels using the appropriate drill bits to prevent the wood from splitting under pressure.

4. Finally, apply a thin coat of wood preservative or clear varnish to the cut and edge surfaces to make the wood more resistant to moisture and minor mechanical impacts.

Combined, these measures usually prevent splitting.

I’m happy to add to hauklo’s points with a brief guide on how to avoid splintering, especially when assembling and installing the BILLY shelves:

1. Edge preparation: As mentioned earlier, lightly sand the edges with fine sandpaper. Always sand in the direction of the grain, never across it, to avoid roughening the wood fibers.

2. Drilling and screwing: It’s important to pre-drill and use a countersink bit so that screw heads don’t cause the wood to split. I recommend inserting screws slowly and carefully, applying gentle pressure.

3. Assembly aids: I often use small felt or rubber pads on the shelf support surfaces. This cushions minor stresses and prevents pressure marks that could later cause splinters.

4. Finishing: If you like, you can seal the edges with a lacquer pen or hard wax oil. This creates smoother edges and protects against moisture, which also helps reduce splintering.

5. Tools and environment: Make sure your tools are sharp and clean—dull saw blades or drill bits increase the chance of splinters. Also, the boards should not be too dry or too damp during assembly, as this affects how easily they may crack.

I hope these steps are helpful!

That is indeed very important. Dull knives or drill bits can easily cause splintering.

My tip: Smooth the edges with 240-grit sandpaper, then rub in hard wax oil, which provides good protection.

I also had problems with splintering edges when assembling my BILLY shelf. It was really frustrating because I wanted to keep the wood in good condition.

What helped me was approaching the task calmly and patiently. I first sanded the edges, then carefully inserted the shelves—not forcing them, but very gently.

After assembly, I also worked on the edges again using fine sandpaper. The result was much better than before.

You shouldn’t let yourself get stressed because if you work hastily, accidents can happen quickly.

I understand how annoying that is—but with the right preparation, it works out!

I always wonder if the issue with splintering edges on the BILLY shelf is due to the inexpensive particleboard or fiberboard used. If you want a sturdy, real wood shelf, you might be better off buying something else—whether solid wood or plywood.

You can sand and paint as much as you like, but with a cheap substrate, there are clear limits.

To me, the discussion about how to get a BILLY shelf without splinters feels like trying to find the best workaround for a product of inherently low quality.

That’s why I’d simply recommend buying a different shelf altogether—you won’t have that problem in the first place.
