IKEA Kitchen Filler Pieces and Cover Panels: Complete Guide
IKEA Kitchen Filler Pieces and Cover Panels: Complete Guide
If the cabinets are the structure of your IKEA kitchen, then filler pieces and cover panels are the cosmetics. These finishing components close gaps, cover raw edges, and transform a collection of modular boxes into a cohesive, built-in-looking kitchen.
Filler pieces and cover panels are often overlooked during the planning phase, but they make a dramatic difference in the final appearance. A kitchen without them looks unfinished. A kitchen with well-installed fillers and panels looks like custom cabinetry.
This guide covers every type of filler and panel in the IKEA SEKTION system, with detailed instructions for measuring, cutting, and installing each one.
Understanding the Terminology
Filler Pieces (Filler Strips)
Filler pieces are narrow strips of material (matching your door finish) that close the gap between the last cabinet in a run and the adjacent wall. They come in standard widths and are cut to fit during installation.
Why fillers are necessary:
- IKEA cabinets come in fixed widths (12, 15, 18, 21, 24, 30, and 36 inches)
- The total width of your cabinet run rarely matches the exact wall-to-wall dimension
- The leftover gap between the last cabinet and the wall needs to be covered
- Fillers also ensure that doors and drawers on end cabinets have enough clearance to open without hitting the wall
Cover Panels (End Panels)
Cover panels are large, flat panels (matching your door finish) that attach to the exposed sides of cabinets. Any cabinet side that is visible — the end of a run, the side facing a doorway, the sides of an island — needs a cover panel to hide the unfinished particleboard.
Deco Strips (Trim Pieces)
IKEA's FORBATTRA deco strips are narrow trim pieces that attach to the tops and bottoms of cabinets and along edges where cover panels meet cabinet faces. They provide a finished frame around the cabinet fronts.
Where Fillers and Panels Are Needed
Walk through your IKEA kitchen plan and mark every location that needs finishing:
Filler Piece Locations
- Between the last cabinet and the wall — on each end of every cabinet run
- Between cabinets and appliances — small fillers next to the refrigerator, range, or dishwasher prevent doors from interfering with appliance handles
- In corner cabinets — where two runs of cabinets meet at a corner, fillers ensure doors from both runs clear each other
- Between upper and wall — if the upper cabinet run is shorter than the lower run, the gap at the end needs a filler
- Adjacent to windows — cabinets next to a window often need fillers to maintain consistent spacing
Cover Panel Locations
- End of cabinet runs — any cabinet side visible from living spaces
- Island sides — all four sides of an island typically need cover panels
- Peninsula sides — the exposed end of a peninsula
- Above refrigerator — the bottom of the cabinet above the fridge is visible and may need a panel
- Dishwasher end panel — if the dishwasher is at the end of a run, a cover panel finishes the adjacent cabinet side
Measuring for Fillers
Standard Filler Widths
IKEA sells filler strips in standard widths, but they are designed to be cut down:
- Cover panel/filler strips are typically sold in widths of about 25 inches (for base) and various widths for upper cabinets
- They can be ripped (cut lengthwise) to any width needed
How to Measure
Important rule: Always measure after cabinets are installed, not before. Real-world dimensions differ from the plan.
For a standard end-of-run filler:
- Install all cabinets in the run and secure them to each other and the wall
- Measure the gap between the last cabinet and the wall at the top, middle, and bottom
- If the wall is not plumb (common in older mid-Atlantic homes), these three measurements will differ
- The filler must be cut to accommodate the widest measurement, then scribed to fit
Scribing Technique
Scribing creates a custom edge on the filler that matches the exact contour of the wall.
Steps:
- Cut the filler strip slightly wider than the widest gap measurement
- Hold the filler strip plumb against the cabinet side, pushed into the corner
- Set a compass (scriber) to the distance between the filler edge and the wall at the widest gap
- Run the compass along the wall, with the pencil marking the filler. The pencil traces the exact wall contour onto the filler
- Cut along the scribed line with a jigsaw (use a fine-tooth blade to minimize chipping on laminate-faced material)
- Sand the cut edge smooth
- Test fit and trim as needed
Pro tip: For dark-colored fillers, use a white pencil or fine-point marker for the scribe line. For light-colored fillers, a standard pencil works fine.
Cutting Techniques
Tools
- Table saw: Best for ripping fillers to width (straight, consistent cuts)
- Circular saw with guide: A straightedge clamped to the filler provides a guide for the circular saw. Good for job-site cuts when a table saw is not available
- Jigsaw: Essential for scribed cuts that follow wall contours
- Router with flush-trim bit: Cleans up scribed edges to a smooth, consistent finish
- Fine-tooth hand saw: For small adjustments and delicate trim work
Minimizing Edge Chipping
IKEA filler strips and cover panels have a melamine or foil face that can chip during cutting. To minimize chipping:
- Score the cut line first with a sharp utility knife before cutting with a saw
- Use a fine-tooth blade (80-tooth or higher for a circular saw, fine-tooth blade for a jigsaw)
- Cut with the good face down when using a circular saw (the blade enters from the bottom, so chipping occurs on the top)
- Cut with the good face up when using a jigsaw (the blade enters from the top)
- Apply painter's tape over the cut line before cutting — this supports the surface fibers and reduces tear-out
Finishing Cut Edges
Raw cut edges on IKEA panels expose the particleboard core, which is not attractive and can absorb moisture. Finish cut edges with:
- Iron-on edge banding in a matching color (IKEA sells matching edge banding for most finishes)
- Touch-up paint or marker for edges that will be hidden against the wall (less critical, but prevents moisture absorption)
- Caulk along edges that meet the wall — this seals the edge and fills any remaining gap
Installing Fillers
Method 1: Screw Through the Cabinet Side
The most secure method:
- Position the filler against the cabinet side
- Clamp it in place with the scribed edge tight against the wall
- From inside the cabinet, drill pilot holes through the cabinet side panel into the filler
- Drive screws from inside the cabinet through to the filler (use screws that penetrate the filler by at least 1/2 inch but do not go all the way through)
- Countersink the screw heads inside the cabinet
Method 2: Construction Adhesive Plus Pin Nails
For fillers in less critical locations:
- Apply a thin bead of construction adhesive to the cabinet side
- Position the filler and press firmly
- Secure with 18-gauge pin nails (brad nailer) while the adhesive cures
- Fill pin nail holes with color-matched filler
Method 3: Pocket Screws
For a clean look with strong attachment:
- Drill pocket screw holes in the back of the filler strip using a pocket hole jig
- Position the filler against the cabinet
- Drive pocket screws from behind the filler into the cabinet side
- Pocket holes face the wall and are hidden
Installing Cover Panels
Measuring Cover Panels
Cover panels need to match the exact height of the cabinet (including the toe kick area for base cabinets) and the exact depth from front to back.
For base cabinet end panels:
- Height: From the floor to the top of the cabinet (typically 34.5 inches plus the toe kick height)
- Depth: From the front edge of the cabinet to the wall (24-5/8 inches for standard depth, adjust if the cabinet is pulled away from the wall)
For upper cabinet end panels:
- Height: Matches the upper cabinet height (30 or 40 inches)
- Depth: Matches the upper cabinet depth (15 inches for standard SEKTION uppers)
Attachment Methods
Construction adhesive plus screws:
- Apply adhesive in a zigzag pattern across the cabinet side
- Position the cover panel flush with the cabinet face
- Secure with screws through the cabinet side panel into the cover panel (from inside the cabinet)
- For additional security, drive a few finish nails through the cover panel face into the cabinet side
- Fill nail holes with color-matched putty
IKEA UTRUSTA bracket system:
IKEA sells cover panel brackets that mount inside the cabinet and grip the edge of the cover panel. This creates a clean, screw-free attachment but is slightly less rigid than adhesive plus screws.
Aligning Cover Panels
The cover panel face should be flush with — or very slightly proud of — the door faces. If the panel sits behind the door faces, it creates a visible step. If it protrudes significantly, it looks bulky.
Alignment tip: Before attaching the cover panel permanently, hold it in position and close the adjacent door. Check that the door face and panel face are aligned. Shim behind the panel if needed.
Common Filler and Panel Mistakes
- Not ordering enough material: Fillers and panels are easy to undercount. Walk through every visible edge and gap in your plan and order 15 percent extra.
- Not scribing to the wall: Cutting a straight edge and butting it against a wavy wall leaves visible gaps. Always scribe.
- Using the wrong adhesive: Hot glue, white glue, and wood glue do not bond well to IKEA's melamine surfaces. Use construction adhesive designed for non-porous surfaces.
- Forgetting to edge-band cut edges: Raw particleboard edges look unfinished and absorb moisture. Edge band every visible cut.
- Installing panels before doors and drawers: Mount doors and drawers first so you can verify panel alignment against the door faces.
Special Situations in Mid-Atlantic Homes
Older homes across the mid-Atlantic present unique filler and panel challenges:
Out-of-square corners: In homes built before modern framing standards, corners are rarely exactly 90 degrees. When two runs of cabinets meet at an out-of-square corner, the filler piece in the corner needs to compensate for the angle. This often means cutting a filler wider at one end than the other and scribing both edges (the wall side and the cabinet side).
Bowed walls: Plaster walls in older Philadelphia, Baltimore, and DC homes often bow in or out over their length. A filler piece against a bowed wall needs to be scribed with extra care — the scribe line will be a curve rather than a straight line. Test fit multiple times before making the final cut.
Non-standard ceiling heights: In homes with 9 or 10-foot ceilings, the gap between the tops of the upper cabinets and the ceiling may be too large for a single filler or trim piece. Consider a combination approach using a soffit or crown molding assembly at the top of the cabinets.
Multiple wall materials: Some older homes have walls made of different materials on different sides of the kitchen (plaster on exterior walls, drywall on interior walls added during a renovation). The texture and contour differences between these materials mean each filler needs to be scribed independently — you cannot assume one wall's contour matches another's.
Filler and Panel Costs
IKEA filler strips and cover panels are relatively inexpensive:
- Cover panels: $30-80 each (depending on size and finish)
- Filler strips: $10-30 each
- Edge banding: $5-15 per roll
Labor is where the cost adds up. Scribing, cutting, and installing fillers is detail-intensive work that takes an experienced installer 4 to 8 hours for a typical mid-size kitchen.
Professional Finishing Makes the Difference
Filler pieces and cover panels are where the difference between a DIY installation and a professional one becomes most visible. The measuring, scribing, and cutting require patience, precision tools, and experience with IKEA's materials.
