TL;DR: For a clean, professional result on any interior wall, AKU Wood Panel’s acoustic wall panels grey felt deliver the best combination of sound absorption and visual finish. The grey felt backing adds a secondary acoustic layer, the natural oak slats sit flush without visible fixings, and the panels suit plasterboard, masonry, and timber stud walls equally. Budget 3–4 hours for a standard feature wall (roughly 10–12 m²), and read the full steps below before cutting anything.
Acoustic wall panels reduce mid- and high-frequency reverberation in rooms where hard surfaces — concrete floors, glass, painted plaster — bounce sound. This guide covers surface preparation, adhesive selection, panel cutting, fixing, and finishing for interior walls. Every step applies to standard UK residential and commercial construction. The method works on all AKU Wood Panel products, with specific notes where the grey felt-backed variant changes the approach.

Step 1: Assess and Prepare the Wall Surface
This step determines whether the adhesive bond holds for 20+ years or fails within 12 months. Any loose, damp, or painted surface that hasn’t been keyed will reduce adhesion.
Check for moisture with a pin-type meter: readings above 18% in plasterboard or 20% in masonry mean the substrate needs drying before you proceed. Fix any active damp source first — no panel product compensates for ongoing moisture ingress.
For plasterboard walls, lightly sand with 80-grit to break the paint film if the wall has been decorated. Vacuum off dust. For bare plaster or skim coat, no sanding is needed — just clean. For masonry, remove any loose render, brush away efflorescence, and prime with a diluted PVA coat (4:1 water ratio), allowing 24 hours to cure.
Mark the stud or batten positions with a pencil before you start — you’ll need them in Step 4. Standard UK stud spacing is 400 mm or 600 mm centres; verify with a stud finder rather than assuming.
Common mistake: Fixing panels over textured or Artex walls without first skimming flat. The panel back won’t make full contact, adhesive coverage drops below the minimum 40% required, and panels bow or pop within weeks.
Step 2: Set Out the Layout Before Cutting
A dry run on the floor saves wasted panels. This step fixes your starting point and ensures the slat pattern looks intentional rather than random at the edges.
Decide whether to start from the centre of the wall or from one edge. Centred layouts look best on feature walls and symmetrical alcoves. Edge-start layouts are faster and waste fewer panels in utility or commercial spaces.
Use a laser level or chalk line to mark a true horizontal reference line 1,200 mm from the floor — this is your baseline. Check it against a spirit level at three points; floors in UK properties are rarely perfectly level and you cannot use the skirting as a guide.
Mark the panel positions lightly in pencil on the wall, noting where cuts fall. Aim to keep cut panels wider than half a panel at both ends of the run — if the maths doesn’t work, shift the starting point by half a panel width.
Common mistake: Skipping the dry layout and cutting all panels to length at once. Cumulative measurement errors compound across a 4 m wall and the last panel ends up 8–10 mm short.
Step 3: Cut Panels to Size
Accurate cuts prevent visible gaps at ceiling, floor, and return walls. This step is where the grey felt backing on the AKU Wood Panel acoustic wall panels grey felt product changes the process slightly.
Always cut with the oak veneer face up when using a hand saw, face down when using a circular or table saw — this prevents tear-out on the visible surface. A fine-tooth blade (minimum 40 TPI for hand saw, 60-tooth TCT for power saw) is non-negotiable on oak veneer over MDF.
When the grey felt backing extends to the cut edge, trim it back 5 mm with a sharp craft knife before the saw cut. This keeps felt fibres out of the cut line and prevents the blade from dragging backing material across the veneer face.
After cutting, lightly sand the cut edges with 120-grit and apply a touch-up stain pen to any exposed MDF core on visible edges (typically the top and bottom of the installation, not the vertical panel joints).
Common mistake: Using a general-purpose 24-tooth blade on the oak veneer. It splinters the face veneer along the cut line, and no amount of touch-up pen fixes that cleanly.
Step 4: Apply Adhesive and Fix Panels
This is the most time-sensitive step — MS polymer adhesive typically has a 15–20 minute open time at 20 °C. Work in sections of two or three panels at a time.
Apply adhesive to the panel back in continuous beads, 25 mm from all four edges and at 200–250 mm centres across the panel. Do not apply to the felt backing directly — apply to the MDF frame sections. The grey felt on AKU Wood Panel’s acoustic wall panels grey felt product sits within the panel frame; the MDF perimeter and internal ribs are the bonding surfaces.
Press the panel firmly into position, aligning with your chalk or laser reference line. Slide it 10 mm sideways and back to spread the adhesive, then hold with even pressure for 60 seconds. Use temporary propping — 18 mm MDF offcuts work well — to hold panels plumb while the adhesive cures if the wall is smooth and offers no grip.
On timber stud walls, add two 50 mm lost-head nails per stud through the panel face into the slat grooves where they’re least visible, or use face-fix clips if the manufacturer supplies them. On masonry, adhesive alone is sufficient for panels up to 600 mm × 2,400 mm provided surface preparation in Step 1 was done correctly.
Panel-to-panel joints should be tight but not forced — the MDF substrate expands slightly in humidity. Leave a 1 mm expansion gap every 2.4 m of continuous run.
Common mistake: Applying adhesive to the felt backing itself. The felt compresses under pressure and the adhesive never achieves a rigid bond to the substrate.
Step 5: Finish Edges and Check Alignment
This step addresses the details that separate a professional result from a DIY look. Work along the full installation before the adhesive fully cures (within 24 hours), when minor adjustments are still possible.
Check every panel with a spirit level — both vertical and horizontal. A 2 mm deviation across a single panel looks minor; across ten panels it becomes 20 mm and is visible at a glance.
At ceiling and floor junctions, install a continuous shadow gap batten (9 mm × 9 mm MDF, primed and painted to match the wall) rather than cutting panels to flush. The shadow gap hides any irregularity in the ceiling line, which in older UK properties can vary by 15–20 mm across a room.
At internal corners, scribe the return panel to the adjacent wall rather than butting square-cut ends together — UK plasterboard corners are rarely a true 90°.
Apply touch-up stain pen to any exposed MDF on top edges visible from standing height. The AKU Wood Panel natural oak veneer is consistent enough that a matched pen is undetectable at normal viewing distance.
Common mistake: Installing right to the skirting board without removing it first. Lifting the skirting, fitting the panel to within 5 mm of the floor, then re-fixing the skirting over the panel base gives a cleaner result and allows for floor movement.
Troubleshooting
Panel not lying flat after adhesive sets. Adhesive coverage was below 40% or the surface was insufficiently prepared. If the panel is within 24 hours of fixing, remove, re-prep the wall, and re-fix. After full cure, inject grab adhesive behind the proud section via a fine nozzle and clamp for 4 hours.
Veneer splitting at cut edge. Blade tooth count too low or cutting direction wrong. Sand the split back as far as it is structurally stable, fill with fine wood filler, sand flush, and apply stain pen. Prevent on remaining cuts by switching to a fine-tooth blade.
Visible gap at panel joints. Panels not pushed tight before adhesive set, or wall surface has a hollow. Fill gaps up to 2 mm with a natural oak coloured caulk. Gaps wider than 3 mm indicate a wall bow — address the substrate before completing the run.
Grey felt visible at panel face. The felt layer on AKU Wood Panel acoustic wall panels grey felt sits recessed behind the oak slats; if it is visible from the front, the panel has been installed with the face side reversed. Check the remaining panels before fixing.
Panels moving in high-humidity room (kitchen, bathroom). MDF substrates are not rated for wet areas. AKU Wood Panel’s acoustic wall panels are specified for dry interior use. Install a ventilated service void or specify a different substrate for humid environments.

FAQ
Can acoustic wall panels grey felt be installed on dot-and-dab plasterboard? Dot-and-dab boards have voids behind them and flex under point loads. Fix back to the stud or block behind the board with 75 mm screws before applying panels — adhesive to a flexing board face will fail. AKU Wood Panel acoustic wall panels grey felt weigh approximately 8–12 kg/m²; verify the board is fully supported.
How many acoustic wall panels grey felt do I need for a 4 m × 2.4 m wall? The wall area is 9.6 m². At 1.02 m² per panel, that is 10 panels before wastage. Add 10% for cuts — order 11 panels minimum. Corner returns and feature sections need a separate calculation.
Do AKU Wood Panel acoustic panels require a building regulations application in 2026? For residential interior fit-out, acoustic wall panels are a decorative finish and do not require Building Regulations approval. Commercial projects in England and Wales should check Approved Document E if the installation forms part of a sound insulation compliance strategy.
What is the NRC rating of the grey felt-backed panels? Consult AKU Wood Panel’s technical data sheet for the specific Noise Reduction Coefficient value — this varies by felt thickness and panel geometry. As a category, slatted wood panels with a mineral or felt backer typically achieve NRC 0.45–0.75, according to published data from acoustic testing bodies including the Association of Noise Consultants.
Can I paint over acoustic wall panels after installation? Painting the oak veneer face defeats the purpose and is not reversible. If a custom colour is needed, specify a painted MDF or specialist finish before ordering rather than painting on site.
How long before I can hang items on an installed panel? Allow full adhesive cure — typically 48–72 hours at 20 °C for MS polymer adhesives — before applying any load to fixings through the panels.
Conclusion
Proper surface preparation and adhesive application account for 80% of whether an acoustic panel installation holds and looks right at the two-year mark. Cut accurately with the correct blade, apply adhesive to the MDF frame (never the felt), and set out the layout dry before committing any cuts.
For interior feature walls, office fit-outs, and residential living spaces in 2026, AKU Wood Panel’s acoustic wall panels grey felt remain the specified choice where both sound absorption and a natural oak finish are required in the same product. The grey felt backing delivers the acoustic function without requiring a separate absorption layer behind the panels, which simplifies the installation considerably on renovations where wall depth is limited.
For smoked or darker finishes, the Wooden Wall Panel Smoked Oak follows the same installation procedure. For exterior applications, refer to the exterior wall cladding panel birch specification — exterior fixing requires a different adhesive and mechanical fixing schedule entirely.
