How to Install Wall Panels Bunnings & Wood Wall Panelling (Complete DIY Guide)

Most wall panel installations go wrong before a single panel touches the wall.

Not because the panels are poor quality. Not because the materials are difficult to work with. And not because decorative wall panelling is overly complicated.

The problem is usually the same thing.

Rushed preparation.

People skip checking whether the wall is level, underestimate how many panels they need, use the wrong adhesive, fail to mark stud locations, or begin installation without a proper reference line. The result is predictable — uneven spacing, drifting alignment, visible gaps, loose panels, and a finished wall that looks nothing like the inspiration image they started with.

That is entirely avoidable.

Wall panels are one of the fastest and most effective ways to transform a room. Whether you choose wall slat panels, decorative MDF panels, tongue and groove boards, or solid timber wall panelling, the right installation can completely change the feel of a space.

They add texture, depth, warmth, and architectural detail that paint alone cannot provide.

This guide explains exactly how to install wall panels from Bunnings and similar hardware systems, how to attach wall panels correctly, how to cut wood panels for walls, and how to avoid the installation mistakes that ruin otherwise good DIY projects.

Read the full process before starting.

What Are Wall Panels?

Wall panels are decorative or functional coverings installed directly onto interior walls to improve appearance, add texture, or enhance acoustic performance.

Unlike flat painted walls, wall panelling creates dimension and visual depth through raised surfaces, slats, grooves, or layered finishes.

Wall slat panels differ from traditional tongue and groove panelling because they intentionally include spacing between each slat. That spacing creates shadow lines that give slat walls their clean, modern architectural appearance.

Common Materials Used for Wall Panels

Solid Wood

Real timber delivers warmth, visible grain texture, and a premium natural finish.

Best for:

• feature walls

• natural timber interiors

• stained finishes

• long-term durability

MDF Panels

MDF wall panels are affordable, smooth, stable, and ideal for painted finishes.

Best for:

• budget DIY projects

• modern interiors

• painted wall panelling

• easy installation

Acoustic Felt-Backed Panels

These combine decorative slats with sound-absorbing felt backing that reduces echo and improves room acoustics.

Best for:

• home offices

• media rooms

• open-plan spaces

Engineered Timber

Offers greater stability than solid timber with less risk of warping or expansion.

Why Choose Wall Panels?

Wall panels are not only decorative.

When installed properly, they improve both the appearance and function of a room.

Main Benefits of Wall Panels

• Create modern feature walls quickly

• Add depth and architectural texture

• Cover imperfect wall surfaces

• Work with contemporary and classic interiors

• Faster to install than traditional renovation methods

• Available in MDF, wood, decorative, and acoustic finishes

• Suitable for beginners and experienced DIY renovators

Many homeowners choose wall panelling because it creates a high-end result without requiring specialist tools or expensive construction work.

Planning Before Installation

Most installation problems begin during the planning stage.

Proper preparation prevents wasted materials, uneven alignment, and poor finishing later.

Measure the Wall Area Correctly

Measure:

• wall width

• wall height

• window openings

• doors

• electrical outlets

• switches

• alcoves and recesses

Never assume walls are perfectly square.

Older properties especially tend to have:

• bowed walls

• uneven plaster

• irregular corners

• slight height variation

Measure multiple points across the wall and use the most restrictive measurement.

Always add an extra 10–15% material allowance for:

• waste

• cuts

• mistakes

• offcuts

Check the Existing Wall Surface

Wall panels can be installed on:

• drywall

• plasterboard

• brick walls

• concrete walls

• tiled walls

• timber-framed walls

Before installation, repair:

• cracks

• loose plaster

• damp areas

• uneven surfaces

• damaged sections

Wall panels follow the surface behind them. If the wall is uneven, the finished installation will also appear uneven regardless of how carefully the panels are fitted.

Choose the Right Panel Material

MDF Panels

Best for:

• painted finishes

• budget-friendly projects

• stable indoor environments

Solid Wood Panels

Best for:

• natural warmth

• premium finishes

• feature walls

Acoustic Panels

Best for:

• reducing echo

• improving sound quality

• modern offices and media rooms

Moisture-Resistant Panels

Essential for:

• bathrooms

• kitchens

• humid environments

Decide on Layout and Direction

Vertical wall panels make ceilings feel taller.

Horizontal panels make narrow spaces feel wider.

Full wall installations create dramatic visual impact, while half-wall panelling offers a more subtle and affordable option.

Tools and Materials Needed

Before starting installation, prepare all tools and materials first.

Stopping halfway through installation to buy missing materials often leads to rushed decisions and mistakes.

Tools

• tape measure

• pencil

• spirit level

• laser level

• stud finder

• circular saw or mitre saw

• drill

• nail gun or hammer

• caulk gun

• sanding block

Materials

• wall panels

• construction adhesive

• screws or finishing nails

• timber battens

• wood filler

• caulk

• primer

• paint, stain, or sealant

How to Prepare a Wall for Panelling

Preparation is what separates professional-looking installations from amateur ones.

Clean the Wall Thoroughly

Remove:

• dust

• grease

• loose paint

• wallpaper residue

• old adhesive

• protruding nails and screws

Construction adhesive bonds poorly to dirty or unstable surfaces.

Locate and Mark Wall Studs

If you plan to use screws or nails, locate wall studs before installation begins.

Mark stud positions lightly in pencil so panels can be fixed securely.

Check for Level and Plumb

Use a spirit level to create:

• a horizontal starting reference line

• vertical plumb lines across the wall

Never trust ceilings, skirting boards, or corners to be straight.

They often are not.

Acclimate the Panels

Allow MDF or timber panels to rest flat in the room for at least 24–48 hours before installation.

This helps minimise movement caused by temperature and humidity changes after fitting.

How to Install Wall Panels Bunnings Step by Step

This is the core installation process.

Follow each stage carefully and avoid rushing ahead.

Step 1: Plan the Panel Layout

Decide whether your panels will run:

• vertically

• horizontally

Plan:

• corners

• joins

• outlet positions

• switch cut-outs

• visible edge finishes

Avoid layouts that leave thin awkward strips at wall edges.

Adjust the starting position if necessary to create balanced spacing.

Step 2: Cut Wood Panels for Walls

Measure every panel carefully before cutting.

For clean cuts:

• support the panel properly

• use a fine-tooth blade

• cut slowly and steadily

• sand rough edges afterwards

When cutting around outlets or switches:

• measure twice

• mark clearly

• cut carefully

Poor cuts are difficult to hide later.

Step 3: Install Battens if Required

Battens are timber strips fixed to the wall before the panels.

Battens are useful when:

• walls are uneven

• surfaces are brick or concrete

• additional support is required

• airflow behind panels is needed

Secure battens into studs or masonry using suitable screws and wall plugs.

Check each batten carefully for level before fixing permanently.

Step 4: Install the First Panel

The first panel determines the alignment of the entire wall.

If it is not level, every panel installed afterwards will magnify the error.

Use your reference line and check the panel with a spirit level before fixing.

Secure using:

• construction adhesive

• finishing nails

• screws where required

Double-check alignment before continuing.

Step 5: Attach Wall Panels

There are three main fixing methods.

Adhesive Method

Apply construction adhesive in a zigzag pattern across the back of the panel.

Press firmly against the wall.

Best for:

• lightweight MDF panels

• smooth plasterboard walls

• decorative panels

Nail Fixing Method

Use finishing nails or a nail gun to secure panels into studs or battens.

Best for:

• timber-framed walls

• additional holding strength

Screw Fixing Method

Screws provide stronger support for:

• solid timber panels

• acoustic panels

• uneven surfaces

• masonry walls

Countersink screw heads slightly below the surface before filling.

Combination Method

For the strongest installation, combine adhesive with nails or screws while the adhesive cures.

Step 6: Continue Installing Remaining Panels

Work steadily across the wall.

After every few panels:

• step back

• check alignment

• verify spacing

• confirm everything remains level

Small alignment problems become obvious quickly if ignored.

Step 7: Finish Edges and Corners

Edges and corners are where installation quality becomes most visible.

Use:

• trims

• end caps

• mouldings

• mitred joins

Fill:

• nail holes

• small gaps

• imperfections

Sand smooth before painting or staining.

Apply caulk where panels meet ceilings, skirting boards, or adjoining walls.

Step 8: Paint, Stain, or Seal the Panels

MDF Panels

Prime first using MDF primer, then apply paint evenly.

Timber Panels

Sand thoroughly before applying:

• oil

• stain

• wax

• varnish

• paint

Acoustic Panels

Do not paint the felt backing because this reduces acoustic performance.

Allow finishes to cure fully before reinstalling outlet covers or fixtures.

How Are Wall Panels Installed on Different Wall Types?

Drywall and Plasterboard

Adhesive usually works well for lightweight panels. Heavier panels benefit from nails or screws into studs.

Plaster Walls

Check for hollow or loose plaster before installation.

Use masonry fixings for heavy panels where necessary.

Brick and Concrete Walls

Battens are often the best solution because they create a flat fixing surface.

Tiled Walls

Panels can sometimes be glued directly over tiles if the tiles are secure and the surface is lightly sanded first.

How to Install Decorative Wall Paneling

Decorative wall panelling is designed mainly for visual impact.

Popular styles include:

• geometric panels

• raised moulding panels

• feature wall systems

• shaker-style panelling

For best results:

• measure carefully

• maintain consistent spacing

• dry-fit panels before permanent fixing

Painting decorative panels the same colour as the wall creates a clean designer-style finish.

How to Install Wall Slat Panels

Wall slat panels are one of the most popular modern interior trends.

They use evenly spaced timber or MDF slats to create texture and shadow lines across the wall.

Vertical Slat Panels

Best for:

• increasing perceived ceiling height

• narrow rooms

Horizontal Slat Panels

Best for:

• widening visual space

• contemporary interiors

Maintain perfectly consistent spacing throughout installation for the cleanest appearance.

How to Do Tongue and Groove Wall Panelling

Tongue and groove boards interlock together for a seamless finish.

Installation process:

1. Start with a perfectly level first board

2. Slot each board into the previous board

3. Secure through hidden edges where possible

4. Continue checking alignment regularly

This method creates a durable and clean traditional wall finish.

How to Attach Wall Panels Securely

The correct fixing method depends on:

• wall type

• panel weight

• moisture exposure

• panel material

Adhesive Only

Best for:

• lightweight MDF

• smooth indoor walls

Nails or Screws

Best for:

• solid timber

• acoustic panels

• uneven walls

Combined Fixing

Provides maximum long-term durability.

Can You Buy Panelling for Walls?

Yes.

Bunnings and similar hardware stores stock:

• MDF wall panels

• timber slat panels

• acoustic panels

• decorative feature panels

• tongue and groove boards

You can purchase:

• full panel kits

• individual boards

Common Mistakes to Avoid

Starting Without a Level Reference

Even a small alignment error becomes obvious across a full wall.

Skipping Wall Preparation

Panels fixed over damp or unstable surfaces eventually loosen or fail.

Incorrect Measurements

One inaccurate cut can waste an entire panel.

Using Too Much Adhesive

Excess adhesive causes:

• messy joins

• uneven alignment

• difficult cleanup

Ignoring Expansion Gaps

Solid timber naturally expands and contracts.

Without gaps, panels may:

• buckle

• split

• separate from the wall

How Much Does It Cost to Install Wall Panels?

Costs vary depending on:

• material choice

• wall size

• installation complexity

• DIY vs professional fitting

Approximate DIY Material Costs

MDF Panels

Usually the most affordable option.

Solid Timber Panels

More expensive but provide premium finishes.

Acoustic Panels

Typically cost more because of specialised backing materials.

Additional costs include:

• adhesive

• fixings

• primer

• paint

• trims

Professional Installation Costs

Professional labour costs increase when:

• walls require repairs

• battens are necessary

• complex cuts are involved

• premium timber finishes are selected

DIY feature walls are significantly cheaper than full professional installations.

Cleaning and Maintenance

Well-installed wall panels are relatively low maintenance.

Routine Cleaning

Use:

• a soft cloth

• microfiber dusters

• vacuum brush attachments

Avoid excessive moisture on MDF panels.

Repainting and Refinishing

Painted MDF can be lightly sanded and repainted over time.

Solid timber panels may require re-oiling or re-staining every few years depending on wear.

Repairing Damaged Panels

Individual slats or sections can often be replaced without removing the entire wall.

Keep spare offcuts from the original installation whenever possible.
