Filling the shelf pin holes is a super easy way to update your IKEA Billy Bookcases or other flat-pack bookcases. This easy, five minute update makes a huge impact with very little time or effort.
I love IKEA bookcases; they’re budget-friendly, have loads of storage, and are super easy to put together.
But there’s one thing I absolutely hate about them – those rows and rows of holes lining the insides.
Sure, it’s super handy that you can adjust the shelves to any height you want. But once your shelves are all placed, those holes just scream cheap.
A couple of months ago, I shared the big beautiful wall of built-in bookshelves I made from IKEA Billy bookcases.
To make the Billy bookcases look like actual built-in wood bookcases, I framed them with MDF, added trim, painted everything.
And at the end of all that work, when I stepped back and looked at them, they were gorgeous.
Or they would have been, except all I could see were those darn holes.
They were everywhere and they were making the entire thing look cheap and thrown-together.
So I did a bit of research and a bit of experimenting and found a very easy way to make those bookshelf holes disappear.
This easy method will work whether you’re doing a huge IKEA hack like I did or you simply want to give your basic IKEA bookcases a quick update.

How to Fill Holes in IKEA Billy Bookcases
IKEA actually sells little plastic plugs that you can stick in to plug the holes.
Unfortunately, these plugs are designed for plugging holes in their kitchen cabinets and not necessarily for bookcases.
I haven’t personally tried these because the nearest IKEA is three hours away.
However, I did find reviewers who shared that they fit the holes in older IKEA Billy bookcases, but not ones sold in the past five years.
They also don’t sit exactly flush with the sides of the bookcase, but have a slight dome to them. So even though those would be a very quick option, they weren’t for me.
Thankfully I found the perfect solution – basic spackling.
Spackling is very inexpensive, it is easy to apply, and it dries to a white that very closely matches most white bookcases.
Plus, it is not difficult to remove. If you decided you want to rearrange your shelves in the future, it is very simple to poke the spackling out with a screwdriver and stick a shelf pin in the hole.
Before beginning the spackling process, decide exactly how you want to arrange your shelves.
Remove the shelf boards to give yourself room to work, but leave the shelf pins in the holes you plan to use for your shelves.
You definitely don’t want to accidentally fill the holes you need!
I had seven bookcases and hundreds of holes to fill so I refined my process as I worked through them.
I started out applying the spackling with a plastic putty knife, but eventually I found that it was much faster to simply rub some into each hole using my finger.
Once you have applied spackling to each hole in one section, wipe off any excess with a slightly damp paper towel or with your finger.
Allow the spackling to dry fully.
As you can see, I always prefer to use DAP Drydex Dry Time Indicator spackling.
It is pink when you apply it and turns white when it is fully dry.
I tend to get impatient to move on to the next step when doing projects and this keeps me from jumping ahead too quickly.
This picture was taken when I first started. You can see that I hadn’t yet figured out that it is much easier to wipe off the excess spackling before allowing it to dry. From left to right: freshly applied spackling, mostly dried spackling, and smoothed spackling.
Once it is dry, you don’t even have to sand it. Since you already removed most of the excess spackling, just gently rub a damp paper towel over the spackling to wipe away any rogue spots.
Since IKEA Billy bookcases are laminate and non-porous, the spackling doesn’t stick well to it and any excess easily wipes away.
The spackled holes blend in beautifully with the white bookcases.
Filling holes for bookcases that are not white
This solution worked beautifully for me because my bookcases are white and so is the spackling, but what if your bookcases aren’t white?
If you are planning to paint your bookcases anyway, simply apply the spackling before painting.
If your bookcases are already painted a color other than white, find the paint swatch that most closely matches your bookcases and use a sample of that paint to paint over just the white spackling circles to make it blend.
And if your bookcases are wood color, you can either find a paint that is a similar color to the wood to paint over just the tiny spackled holes, or you can find wood look hole plugs online – just be sure to measure first so you get the right size for the your bookshelf holes.
Such a quick and easy update and it truly makes such a difference!
Once all the holes had disappeared, I could finally look at my new wall of bookcases with a real sense of pride and satisfaction.
