Flooring Fundamentals
Main Types of Flooring Used in Melbourne
Melbourne homeowners can choose from several major flooring
categories. Each behaves differently in terms of moisture,
impact resistance, acoustics, installation method, maintenance
and appearance.
Hybrid Flooring
A rigid floating floor typically built around a composite core
with a decorative surface and protective wear layer. Hybrid is
popular in residential applications because it combines easy
maintenance with good dimensional stability and moisture resistance.

Laminate Flooring
Laminate uses a high-density core with a printed décor layer and
durable surface coating. It is generally installed as a floating
floor and is commonly chosen for value, scratch resistance and
realistic timber visuals.
Explore Laminate Flooring
Engineered Timber
Engineered timber combines a real timber wear layer with a
multi-layer structural core. It provides the appearance and feel
of natural timber while offering improved dimensional stability
compared with many traditional solid timber applications.
Explore Engineered Timber
Herringbone & Chevron
Herringbone and chevron floors use shorter timber boards arranged
in geometric patterns. Correct layout, adhesive selection and
subfloor preparation are particularly important for these installations.
Explore Herringbone & Chevron
Bamboo Flooring
Bamboo flooring is manufactured from compressed bamboo fibres
rather than traditional timber boards. Depending on the product,
it can provide a hard and durable surface with distinctive grain
characteristics.
Explore Bamboo Flooring
Carpet
Carpet provides softness, thermal comfort and acoustic absorption.
Fibre type, pile construction, density, underlay and intended use
all affect how a carpet performs.

Buying Advice
How Do You Choose the Right Flooring?
There is no single flooring type that is best for every home.
The right choice depends on the room, household, subfloor,
budget and the performance characteristics that matter most to you.
Quick answer:
Start by deciding what matters most: natural appearance, water
resistance, scratch resistance, comfort, acoustics, price or ease
of maintenance. Then eliminate flooring types that do not suit the
installation environment or subfloor.

do not remove waterproofing requirements for building elements in wet
areas.
Installation Methods
Floating vs Glue-Down Flooring Installation
The installation method can affect how a floor feels underfoot, how it
handles movement, how easily it can be repaired and what subfloor
preparation is required. The correct method depends on the flooring
product, manufacturer requirements and the condition of the substrate.
Floating Installation
A floating floor is not permanently bonded to the subfloor. The boards
connect to each other and sit over an approved underlay or attached pad.
- Common for hybrid and laminate flooring.
- Also used with selected engineered timber and bamboo products.
- Requires perimeter expansion space.
- Subfloor flatness is still critical.
- Usually faster to install than full-spread adhesive systems.
Glue-Down Installation
Glue-down flooring is bonded directly to the prepared substrate using
an adhesive system approved for the flooring product and site conditions.
- Common for engineered timber and herringbone flooring.
- Standard method for many vinyl / LVP products.
- Can provide a firmer, more solid feel underfoot.
- Requires careful substrate preparation and adhesive selection.
- Moisture conditions must be assessed before installation.
Quick answer:
Floating installation is typically simpler and allows the floor to move as
a connected system. Glue-down installation bonds the floor directly to the
substrate and generally provides a more fixed feel. Neither method is
automatically better in every situation; the product specification and
site conditions should determine the method.
Before Installation
Why Subfloor Preparation Matters
A high-quality floor can still perform poorly if it is installed over an
unsuitable substrate. Flatness, stability, moisture, cleanliness and
structural condition should be checked before installation begins.
01
Inspect
Check the substrate for movement, damage, contamination, cracks and
obvious high or low areas.
02
Measure
Assess flatness and levels using appropriate measuring equipment and
compare the result with the flooring manufacturer’s requirements.
03
Prepare
Grinding, patching or self-levelling compounds may be required where
the substrate is outside the permitted tolerance.
04
Recheck
The prepared substrate should be checked again before the flooring
installation starts.
Important:
There is no single flatness number that should be assumed for every floor.
Requirements can vary between flooring systems and manufacturers. Always use
the installation specification for the exact product being installed.
Floor Preparation
Floor Levelling, Grinding and Patching
Levelling does not necessarily mean making the entire floor perfectly
horizontal. In flooring work, the key objective is usually to create a
sufficiently flat and stable surface for the selected flooring system.
Grinding
Grinding is commonly used to reduce isolated high spots, remove
contamination or improve transitions between areas.
Self-Levelling Compound
Self-levelling or smoothing compounds can be used to fill low areas and
improve substrate flatness when applied over a suitably prepared and
primed surface.
Key distinction:
“Level” and “flat” are not the same thing. A floor can be slightly sloped
but still be flat enough for installation. Flooring manufacturers usually
focus primarily on flatness tolerance and substrate suitability.
Moisture Management
Moisture Testing Before Flooring Installation
Moisture can affect adhesives, timber-based flooring, coatings and
dimensional stability. Concrete slabs and timber substrates should be
assessed where required before installation, particularly for glue-down
systems and moisture-sensitive products.
Concrete Subfloors
New or existing concrete can contain moisture that is not visible at the
surface. Where required, moisture testing should be carried out using a
method appropriate to the flooring and adhesive system.
Timber-Based Subfloors
Particleboard, plywood and timber substrates can move with moisture
changes. Their condition, ventilation and moisture content should be
considered before installing sensitive flooring systems.
Do not rely on appearance alone.
A slab may look dry while still containing enough moisture to affect an
adhesive or flooring system. Product-specific testing and moisture limits
should be followed.
Existing Floors
Can New Flooring Be Installed Over Existing Floors?
In some cases, yes. The existing surface must be stable, clean, sufficiently
flat and compatible with the new flooring system. Door clearances, finished
floor height and transitions also need to be considered.
| Existing Surface |
Can It Sometimes Stay? |
Main Considerations |
| Tiles |
Yes |
Tiles must be secure and reasonably flat. Grout lines, height
differences and transitions may require preparation.
|
| Concrete |
Yes |
Flatness, cracks, contamination and moisture conditions must be checked.
|
| Existing Timber |
Sometimes |
Movement, squeaks, stability, ventilation and compatibility must be assessed.
|
| Carpet |
No for hard flooring |
Carpet and soft underlay are generally removed before hard flooring installation.
|
| Old Vinyl |
Sometimes |
Condition, adhesion, flatness and product compatibility must be confirmed.

Flooring Accessories
What Does Flooring Underlay Do?
Underlay can provide acoustic separation, cushioning, thermal performance
and support for a floating floor system. The correct type depends on the
flooring product and installation environment.
Hard-Floor Underlay
- Used under compatible floating flooring systems.
- Can help reduce impact sound.
- May provide vapour-management features depending on the product.
- Must meet the flooring manufacturer’s requirements.
Carpet Underlay
- Adds cushioning and comfort underfoot.
- Can improve thermal and acoustic performance.
- Can influence the way carpet feels and performs.
- Should suit the carpet type and intended use.
Detail Work
Flooring on Stairs and Stair Nosing
Stair installations require more detailed cutting and finishing than
standard floor areas. Nosing profiles, tread dimensions, substrate
condition and product suitability should all be considered.
Why stair nosing matters:
The nosing forms the visible front edge of the stair tread and helps create
a clean, finished transition. Depending on the flooring system, it may be
manufactured from matching flooring or supplied as a dedicated profile.
Bathrooms & Wet Areas
Does Waterproof Flooring Replace Bathroom Waterproofing?
No. A flooring product described as waterproof does not remove the
waterproofing requirements that apply to the building elements beneath
and around it.
Australian building requirements:
NCC wet-area provisions distinguish between waterproof and water-resistant
building elements. For example, timber-based floors in certain wet-area
locations require waterproofing. Product marketing claims for a floorboard
do not replace these building requirements.
Everyday Living
What Flooring Is Best for Homes With Pets?
Pet-friendly flooring should balance scratch resistance, moisture
resistance, comfort, traction and ease of cleaning. No flooring is
completely scratch-proof, so product construction and surface finish
matter more than marketing labels alone.
Hybrid Flooring
Often a practical choice for pets because many hybrid products combine
moisture-resistant construction with durable wear layers and easy cleaning.
Laminate Flooring
Many laminate floors provide strong surface abrasion resistance, although
water resistance varies significantly between products.
Engineered Timber
Real timber provides a premium natural surface, but claws, grit and
furniture movement can mark the coating or timber depending on species
and finish.
Pet-owner tip:
Keeping claws trimmed, using entry mats and removing grit regularly can reduce
visible scratching on almost any hard floor.
Family Homes
Flooring for Families and High-Traffic Homes
In busy homes, durability is only one part of the decision. Cleaning,
acoustics, comfort, slip characteristics and how easily damage can be
repaired should also be considered.
Easy Cleaning
Smooth hard floors are generally easier to sweep and mop after everyday
spills, crumbs and pet hair.
Comfort & Noise
Carpet offers greater softness and sound absorption, while hard floors
may benefit from acoustic underlay where the flooring system allows it.
Durability
Look beyond the product name and compare the actual wear layer, surface
rating, warranty conditions and intended use classification.
Surface Performance
Scratch Resistance vs Dent Resistance
Scratch resistance and dent resistance are different properties. A floor
can resist indentation well while still showing surface scratches, or have
a durable coating over a comparatively softer core.
Scratch Resistance
Scratch resistance mainly relates to the surface coating, wear layer,
finish and how abrasive particles interact with the floor.
Dent / Indentation Resistance
Dent resistance refers more closely to how the material responds to
concentrated pressure or impact from furniture, heels or dropped objects.
Timber Hardness
What Is the Janka Hardness Rating?
The Janka test measures a timber species’ resistance to indentation.
It is commonly used to compare the hardness of different timbers, but it
should not be treated as a direct measure of scratch resistance.
Quick answer:
A higher Janka value generally means the timber is more resistant to
indentation. It does not automatically mean the surface coating is more
resistant to scratching.
Technical reference:
ATFA describes timber hardness as resistance to indentation and notes that
the most commonly used hardness figures are obtained using the Janka test.
Laminate Performance
What Does an AC Rating Mean on Laminate Flooring?
AC ratings are used to communicate the abrasion and wear performance of
laminate flooring. Higher classifications are generally intended for
heavier traffic conditions, although suitability should always be checked
against the specific manufacturer’s product documentation.
Do not choose laminate on AC rating alone
Thickness, locking system quality, moisture resistance, edge treatment,
core density and warranty conditions can all affect real-world performance.
Two laminate products with similar AC ratings can still behave differently
in moisture exposure, sound, feel and dimensional stability.
Product Construction
What Is a Flooring Wear Layer?
The term wear layer refers to the surface layer designed to protect the
decorative or structural layer beneath it. How it is measured depends on
the flooring category.
Hybrid & Vinyl
Wear layers are commonly described by thickness or product-specific
performance classifications.
Engineered Timber
The timber veneer or lamella thickness influences how much real timber
is available above the structural core.
Laminate
Laminate performance is usually described through its protective overlay,
abrasion classification and manufacturer specification rather than a
timber-style veneer thickness.
Floor Movement
Why Do Floors Need Expansion Gaps?
Many flooring products change dimension as temperature and moisture
conditions change. Expansion allowance helps prevent the floor from being
trapped against walls, cabinetry or other fixed objects.
Perimeter Expansion
Expansion space is generally left around walls and fixed vertical
structures, then concealed by skirting, scotia or another approved profile.
Intermediate Expansion
Large floor areas, long runs or particular product systems may require
additional movement joints within the floor. Manufacturer instructions
determine when these are necessary.
Technical reference:
ATFA notes that seasonal moisture changes can cause timber-related flooring
products to expand and contract, so suitable expansion allowance needs to be
incorporated during installation.
Finishing Details
Skirting Boards, Scotia and Caulking Explained
Perimeter finishing is both visual and functional. The selected detail
should conceal required movement space without restricting normal floor movement.
Skirting Boards
Skirting can be installed or reinstalled over the flooring perimeter to
conceal expansion space and provide a traditional wall-to-floor finish.
Scotia
Scotia is a small trim fixed around the perimeter when existing skirting
remains in place. It covers the expansion gap without removing the skirting.
Caulking
Flexible sealants are useful in selected finishing situations, but rigidly
sealing a floor that needs movement space can interfere with its ability
to expand and contract.
Floor Care
Flooring Cleaning and Maintenance Basics
Correct maintenance helps preserve appearance, performance and warranty
coverage. Always follow the care instructions supplied for the exact product.
Remove Grit
Sweep or vacuum regularly because loose grit can act like an abrasive
under footwear and furniture.
Clean Spills Quickly
Promptly remove spills using a method suitable for the flooring product
rather than allowing liquid to sit unnecessarily.
Protect Furniture
Use suitable protective pads and avoid dragging heavy furniture directly
across the floor.
Follow Warranty Care
Cleaning products and equipment should be compatible with the flooring
manufacturer’s warranty requirements.
For carpet:
The Carpet Institute of Australia recommends regular vacuuming, prompt spot
treatment and professional corrective cleaning at suitable intervals, while
also following the carpet manufacturer’s care and warranty instructions.
Troubleshooting
Common Flooring Problems and What Can Cause Them
Flooring problems are not always caused by the floorboard itself.
Installation, moisture, site conditions, maintenance and building movement
can all affect how a finished floor performs.
Buckling or Lifting
Possible causes include insufficient expansion allowance, moisture,
restricted movement, unsuitable substrate conditions or installation issues.
Gapping
Timber and timber-related flooring may show gaps as moisture content and
relative humidity change. Seasonal movement can be normal within appropriate limits.
Squeaking or Movement
Possible causes include substrate movement, uneven surfaces, structural
movement or interactions between flooring components.
Visible Scratches
Grit, pet claws, furniture movement and hard debris can mark the surface
even when a product is marketed as scratch-resistant.
Cupping or Crowning
Timber distortion can relate to moisture imbalance, environmental changes
or conditions affecting different parts of the board.
Edge or Joint Damage
Excessive movement, moisture exposure, damaged locking systems or poor
substrate conditions may contribute to joint-related problems.
Important:
Diagnosing a flooring issue properly often requires looking at the whole system:
product, subfloor, installation method, moisture conditions, expansion allowance
and how the space has been used.
Budget Planning
What Affects Flooring Cost in Melbourne?
The final cost of a flooring project depends on much more than the price
per square metre of the product. Installation method, floor preparation,
removal work, stairs, trims, access and site conditions can all affect
the total project cost.
Flooring Product
Product cost varies according to construction, thickness, surface finish,
timber species, wear layer, brand and warranty.
Installation Method
Floating installation, glue-down installation and patterned layouts such
as herringbone require different levels of labour, materials and preparation.
Subfloor Preparation
Grinding, patching, moisture treatment and levelling can add significantly
to project cost when the existing substrate is outside the required tolerance.
Removal & Disposal
Removing carpet, tiles, laminate, timber or other existing floor coverings
can involve additional labour, disposal and preparation work.
Stairs & Finishing
Stair nosing, skirting, scotia, trims and transition profiles involve
additional cutting, finishing and material.
Site Access
Apartments, restricted parking, upper levels, furniture movement and
difficult delivery access can affect labour and logistics.
Buying tip:
Compare complete project quotes rather than product price alone. A lower
board price may not result in a lower installed cost if preparation,
accessories or installation scope differ.
Room-by-Room Guide
Best Flooring Options by Room and Lifestyle
Different rooms place different demands on flooring. Moisture exposure,
traffic, acoustics, comfort and cleaning requirements should all influence
the final choice.
Living Rooms
Hybrid, laminate, engineered timber and carpet can all work well depending
on the desired balance of durability, appearance and comfort.
Bedrooms
Carpet is popular for softness and acoustic comfort, while timber-look
hard floors provide easy cleaning and visual continuity.
Kitchens
Moisture resistance and easy cleaning are usually priorities. Product
suitability should be confirmed before installation.
Upstairs Areas
Acoustic performance becomes more important upstairs, particularly in
multi-storey homes and apartments.
Rental Properties
Durability, maintenance requirements, replacement cost and appearance
are often key considerations.
Homes With Pets
Durable surfaces, straightforward cleaning and moisture resistance are
commonly prioritised, while traction and comfort should also be considered.
Local Conditions
Melbourne Climate and Flooring Movement
Indoor temperature and humidity can change throughout the year, and
timber-based flooring responds to changes in moisture conditions.
Installation and ongoing care should allow for normal dimensional movement.
Why indoor conditions matter
Timber and timber-related flooring can expand when moisture content rises
and shrink when conditions become drier. This is why correct expansion
allowance, acclimatisation where required and stable indoor conditions are important.
Direct sunlight, heating, cooling and ventilation can also create localised
differences across a floor. Manufacturer instructions should be followed
for the exact product and installation system.
Apartments & Multi-Residential
Acoustic Flooring Requirements in Apartments
Flooring in apartments may need to satisfy acoustic requirements in addition
to the flooring manufacturer’s installation instructions. Impact sound from
footsteps and hard flooring can transfer through the floor structure to
neighbouring apartments.
Before Choosing the Floor
- Check owners corporation or body corporate requirements.
- Confirm whether acoustic test reports or certificates are required.
- Check the approved underlay or flooring system.
- Confirm finished floor height and transitions.
Why Hard Flooring Changes Noise
Carpet naturally absorbs more impact sound than many hard flooring
finishes. When carpet is replaced with timber, laminate, hybrid or other
hard flooring, an appropriate acoustic system may be needed to control
impact noise.
Apartment owners:
Do not assume that a product’s acoustic underlay automatically satisfies your
building’s requirements. The complete flooring system and the building’s
applicable acoustic criteria should be checked before installation.
Technical reference:
The National Construction Code includes requirements for controlling airborne
and impact sound transmission through floors in Class 2 and Class 3 buildings.
ABCB guidance also notes that replacing carpet with hard flooring can reduce
impact-sound isolation performance.
Flooring FAQ
Frequently Asked Flooring Questions
These answers cover common questions we hear from Melbourne homeowners
comparing flooring products, installation methods and floor preparation.
What flooring is best for Melbourne homes?
There is no single best flooring type for every Melbourne home.
Hybrid and laminate are often chosen for low-maintenance living,
engineered timber for a real timber finish, carpet for softness and
acoustics, and vinyl / LVP for low-profile resilient applications.
Is hybrid flooring waterproof?
Many hybrid products use water-resistant or waterproof core materials,
but performance claims vary by manufacturer. Waterproof flooring does
not replace building waterproofing requirements in bathrooms and other wet areas.
Is laminate flooring waterproof?
Some laminate products offer enhanced water resistance, while others
are more moisture-sensitive. Always check the exact product specification
and warranty conditions.
What is the difference between hybrid and laminate flooring?
Hybrid generally uses a rigid composite core and is commonly selected
where moisture resistance is a priority. Laminate typically uses a
high-density fibreboard core with a decorative layer and protective overlay.
Is engineered timber real timber?
Yes. Engineered timber has a genuine timber surface layer bonded to
a multi-layer structural core.
What is LVP flooring?
LVP stands for Luxury Vinyl Plank. It is a resilient flooring product
designed to replicate timber or other decorative finishes and is commonly
installed using adhesive systems.
What is SPC flooring?
SPC usually refers to Stone Plastic Composite or Stone Polymer Composite
flooring. It uses a rigid mineral-filled core and is common in hybrid
flooring products.
Do I need underlay under my flooring?
That depends on the flooring system. Floating laminate, engineered timber
and some other systems may require approved underlay. Some hybrid products
include an attached pad. Glue-down systems generally use adhesive instead
of traditional floating-floor underlay.
Can flooring be installed over tiles?
In some situations, yes. Existing tiles must be stable, clean and sufficiently
flat. Finished floor height, grout lines, transitions and manufacturer
requirements should also be considered.
Can flooring be installed directly over concrete?
Many flooring systems can be installed over concrete when the slab is
suitable. Flatness, surface condition, cracks and moisture should be
assessed before installation.
Does my floor need to be level before installation?
The important requirement is usually flatness rather than making the
entire floor perfectly horizontal. The substrate must meet the tolerances
specified by the flooring manufacturer.
What is the difference between floating and glue-down flooring?
Floating floors connect to each other and are not fully bonded to the
substrate. Glue-down flooring is adhered directly to the prepared subfloor.
Product type, site conditions and manufacturer requirements determine
which method is appropriate.
Which flooring is best for dogs?
Many pet owners choose hybrid or laminate because they can offer durable
surfaces and straightforward cleaning. No floor is completely scratch-proof,
so claw maintenance, mats and regular cleaning remain important.
What does Janka hardness mean?
Janka measures a timber species’ resistance to indentation. A higher Janka
value generally indicates greater resistance to denting, but it is not a
direct measurement of surface scratch resistance.
Why do timber floors expand and contract?
Timber and timber-related flooring respond to changes in moisture and
relative humidity. More humid conditions can increase moisture content
and cause expansion, while drier conditions can cause shrinkage and gapping.
Why do floors need expansion gaps?
Expansion gaps provide space for normal dimensional movement. Without
enough allowance, the floor may become restricted against walls or fixed
objects and develop performance problems.
Can you use caulking around a floating floor?
Caulking may be appropriate in selected finishing details, but it should
not prevent required floor movement. The flooring system’s expansion
requirements must always be maintained.
What is the difference between skirting and scotia?
Skirting is the larger trim fixed to the base of the wall. Scotia is a
smaller profile often used when existing skirting remains in place and
an expansion gap needs to be concealed.
How long does flooring installation take?
Installation time depends on area size, product type, pattern, floor
preparation, stairs, furniture and access. Subfloor preparation can add
significant time where grinding, patching or levelling is required.
What causes flooring to buckle or lift?
Possible causes include restricted expansion, moisture, unsuitable
substrate conditions, installation issues or fixed objects preventing
the floor from moving normally.
Why are gaps appearing in my timber floor?
Timber can shrink during drier conditions and expand when humidity rises.
Seasonal gapping can occur depending on timber species, board width,
installation conditions and indoor climate.
How should carpet be maintained?
Regular vacuuming, prompt treatment of spills and stains, suitable entrance
matting and periodic professional cleaning are key parts of carpet maintenance.
Always follow the manufacturer’s care and warranty instructions.
