Filler panels are typically used with kitchen cabinetry. Yet, you can use filler panels anywhere to give freestanding cabinets a more custom look. We did just that with the PAX cabinets in our nursery.
We added filler panels beside and along the tops of the cabinets and painted them the wall colour. Its a small detail but one which creates a much more finished look. You can see what the nursery looked like before here.
Installing filler panels is easy and there are different ways to go about it. This is the method we use:
1. Find your materials to make the filler. Ikea sells various sizes of filler panels or you can use toe kicks too. We usually just dig into our MDF scraps to make our fillers.
2. Make the cleat. The cleat is the supporting strip of wood that sits behind the filler panel. It provides stability and something for the filler to adhere to. Measure the depth of your filler panel (we used 1/2" MDF) and set the cleat that distance back from the face of the cabinet. We used carpenter's glue to attach the cleat to the wall and held it in place with painter's tape while the glue dried.
3. Attach the filler panel to the cleat. Again, we used carpenter's glue to adhere the filler to the cleat. The filler likely won't be touched much so glue is strong enough for this application.
4. Fill in any gaps with paintable silicone. Oh, DAP, you hide so many secrets :)
And there you go - the cabinets look much nicer, don't you think? Its amazing how such a small detail can enhance the look and feel of a room.
