Timber Wall Panelling
Wall panelling for a feature wall, hallway, bedroom or stairwell — from simple painted MDF tongue-and-groove to full solid hardwood Shaker panels. Adds character that paint alone cannot match.
What you'll need
Materials
- Panel boards (MDF for painted, solid timber for stained/oiled), 18-22mm rails and stiles, 6-9mm panel infill (MDF or plywood for painted, solid timber for natural finish), grab adhesive, brad nails, caulk, primer and paint or oil.
Tools
- Mitre saw, brad nailer with finish nails (or hammer + nail set), spirit level (long), tape measure, stud finder, decorator's caulk gun, sandpaper, paint or oil supplies.
Material complexity: Medium
Allow 10% on MDF for rips and the boards you reject at the wall. Oak needs more — buy an extra stile length.
Main risk: Setting-out that is not centred on the wall — the grid looks drunk, and you only notice when the paint is dry.
Cut list
One typical 4m dado wall, 1200mm high. Painted MDF is the lower cost band; oak the upper.
- Horizontal rails ×218×95mm × 4000mm (bottom/skirting line and dado rail). Join on a stud if you cannot buy 4m
- Vertical stiles ×518×95mm × 1010mm (1200 minus two 95mm rails) — two ends and three intermediates, giving four panels about 850mm wide on a 4m wall
- Panel infill ×46–9mm MDF or plywood, sized to the openings minus a 2–3mm movement gap all round for oak; painted MDF can sit tighter
- Painted version: two 2440×1220mm sheets of 18mm MDF for rails/stiles (rip them down) plus one 6mm sheet for infill, grab adhesive, 18-gauge brads, caulk, primer and paint
- Oak version: the same rail and stile count in 18–20mm oak, oak-veneered or solid panels, grab adhesive plus hidden screws or traditional joints, then oil
Step-by-step
Draw the whole wall in pencil
Mark a 1200mm dado line, level, across the 4m. Divide the width so you have four equal panels and five stiles (two ends, three middles). Stand at the door and look. Move the lines until the end panels match — do not start from one corner and hope.
Tip: A paper storey rod (a stick marked with every rail and stile) is faster than measuring from the tape fifty times.
Rip the rails and stiles
From 18mm MDF (or oak), rip 95mm-wide rails and stiles. Cut two 4000mm rails and five 1010mm stiles for a 1200mm dado. Ease the show arrises slightly so paint does not chip.
Fix the rails, then the stiles
Find the studs. Bed the bottom rail and the dado rail in grab adhesive and brad them into studs. Drop the stiles in on your pencil marks, same method. Check every opening with a tape — this is your last chance to keep the grid even.
Watch out: Adhesive on loose wallpaper or blown plaster is not a fixing. Cut back to sound plaster or hit a stud.
Drop in the panels
Cut 6–9mm infill to each opening. Painted MDF can sit close. Oak veneer or solid panels need a 2–3mm gap all round and must not be glued on all four edges — they have to move. A few dots of adhesive in the centre of an MDF panel is enough.
Caulk, prime and paint — or oil
Caulk every line against the wall and every internal corner. Sand the caulk smooth. Prime MDF (it drinks the first coat) then paint. Oil oak and keep a little leftover for the first heating-season touch-up, when caulk lines sometimes crack at the corners.
Tip: Painted panelling lives or dies on the caulk line. Take an evening over it.
Tips & traps
- Starting at one end and finishing on a 40mm sliver.
- No stud finding — adhesive on wallpaper over blown plaster.
- Skipping caulk, so every shadow line looks like a gap.
- Gluing a solid oak panel in tight — it will split when the heating comes on.
Planning & timber detail
Why build this?
Wall panelling is the highest-impact interior change you can make in a weekend per wall. It adds depth that paint alone cannot. A Shaker grid is now the usual UK hallway and bedroom upgrade, and it is within reach if the setting-out is honest.
Where it works best
Hallways, stairwells, bedrooms, dining rooms. Avoid bathrooms unless you use moisture-resistant materials throughout. Works on flat plaster; uneven walls need shimming behind the frame.
Planning notes
Mark the whole wall in pencil before you fix anything. Stand back — proportions read differently in the room than on paper. Adjust panel widths so the run starts and ends with equal panels, not one full and one tiny.
Typical sizes
Default: 4m-long dado at 1200mm high. Five vertical stiles (two ends plus three intermediates) and two horizontal rails (skirting line and dado rail), 18–22mm × 70–95mm, with 6–9mm panel infill.
Panel proportions around 1:1.4 read best. Adjust widths so the wall starts and ends with equal panels, not one full and one sliver.
Default dimensions
Default wall: 4m long, dado at 1200mm.
Rails and stiles: 18–22mm × 70–95mm.
Stiles: 4–5 on a 4m wall. Panel infill 6–9mm.
Panel width: 600–900mm. Aim for even end panels.
Design variants
Painted MDF Shaker (this page) — the usual hallway upgrade. Fast, stable, takes paint well.
Oak Shaker — same grid, more money, more movement. Leave the panels floating in the frame.
Tongue-and-groove dado — 95–145mm boards, no grid. Faster, more cottage than Shaker.
Above-door height — 1800mm instead of 1200mm. More timber, same method.
Suitable timber options
MDF for painted grid panelling — the universal default. Solid oak for natural-finish premium look. Pine for budget natural or painted character. Birch ply for a modern flat-panel modernist look. Walnut or dark-stained ash for dramatic feature walls.
Fixing and finishing
Grab adhesive plus a few 18-gauge brads into studs is the standard for painted grid panelling. Find the studs first. Caulk every joint to the wall and every internal corner; sand smooth before primer. For oak frame-and-panel, use pocket-holes or mortise-and-tenon on the frame and let the panels float — do not glue a solid oak panel in on all four edges.
Use grab adhesive plus brad nails into studs for grid panelling — much faster than fully traditional joinery and indistinguishable when painted. Caulk every joint between panelling and wall, plus every internal corner. Sand caulk smooth before priming.
Maintenance
Touch up paint scuffs annually. Re-oil natural finishes every 3-5 years. Caulk lines may crack at corners after first heating season — re-caulk and repaint.
After first heating season, walk the panelling and re-caulk any cracks at corners. Spot-prime and repaint affected areas.
Timber behaviour
Durability
Indoor work, so this is about knocks, not rot. Hallways and stairwells take the hits — MDF or hardwood, not soft pine if you do not want to retouch every month. Skip bathrooms unless every piece is moisture-resistant. MDF is stable; solid oak panels must be able to move inside the frame.
Movement
MDF is essentially stable. Solid timber panelling moves with humidity — design with the movement (rails fixed, panels floating in grooves, traditional frame-and-panel). Modern grid panelling (rails glued to flat wall) ignores this because rails are short enough not to crack.
