Engineered Wood Flooring Installation 2025 Guide

Engineered wood flooring has become a top choice for homeowners and professionals alike—offering the rich, natural appearance of solid wood with added strength and flexibility. Whether you’re tackling a full home renovation or refreshing a single room, installing engineered wood flooring can dramatically elevate your interior. In this 2025 guide, we’ll walk you through everything you need to know to achieve a flawless, long-lasting installation.

What is Engineered Wood Flooring?

Engineered wood flooring is crafted from multiple layers of high-quality materials, typically consisting of a core of plywood, HDF (High-Density Fibreboard), or softwood, topped with a real hardwood veneer. This layered construction gives engineered wood flooring its key advantage: dimensional stability. Unlike solid wood, which is cut from a single piece of timber, engineered flooring is far less susceptible to warping, swelling, or shrinking due to changes in temperature and humidity.

The top layer, also known as the wear layer, is made from genuine hardwood such as oak, walnut, or ash—giving it the same rich, natural appearance as traditional solid wood flooring. However, because the core layers are made from more abundant materials, engineered wood flooring uses less slow-growing hardwood, making it a more sustainable choice without compromising on looks or performance.

Its construction allows it to be installed in places where solid wood might not be suitable, such as over underfloor heating or in areas with fluctuating moisture levels. These qualities make it a go-to solution for homeowners and trade professionals seeking a balance of beauty and resilience.

Benefits of Engineered Wood Flooring

Engineered wood flooring comes with a range of advantages that make it stand out in both domestic and commercial settings:

1. Exceptional Stability

Thanks to its layered construction, engineered wood is far more resistant to the natural expansion and contraction that occurs with changes in humidity. This makes it a dependable choice for areas with variable climate conditions or where central heating is used frequently.

2. Compatible with a Wide Range of Subfloors

One of the biggest practical advantages is that engineered wood can be installed over concrete, plywood, existing floorboards, and even some types of vinyl or tile. This versatility makes it a favourite in renovation projects where the subfloor may vary between rooms.

3. Underfloor Heating Friendly

Unlike solid wood, engineered wood flooring is suitable for use with underfloor heating systems, provided the right specifications and installation methods are followed. The stability of its structure allows it to tolerate temperature changes without damage—offering warm comfort underfoot without compromising the integrity of the floor.

4. Environmentally Responsible

Engineered wood flooring is an eco-friendlier alternative to traditional solid wood. Since only the top layer is made from slow-growing hardwoods, and the core can be manufactured from faster-growing, sustainable timber or recycled wood fibres, it helps to reduce the environmental impact without sacrificing visual appeal.

5. Real Wood Look and Feel

With its genuine hardwood top layer, engineered wood looks and feels just like solid wood. It can even be sanded and refinished—depending on the thickness of the veneer—extending its lifespan and maintaining its visual charm over the years.

When to Choose Engineered Wood Flooring

Engineered wood flooring is a highly adaptable option that suits a wide variety of spaces in both residential and commercial environments. Here’s when and where it really shines:

Living Rooms and Bedrooms

These are ideal settings for engineered wood. In these lower-moisture environments, the floor’s natural look enhances warmth and comfort, while its stability ensures long-term performance.

Kitchens

Engineered wood can be used in kitchens, provided care is taken. Spills should be wiped up promptly, and adequate ventilation should be maintained to control humidity. Choosing an engineered wood floor with a strong finish or additional moisture-resistant core can help enhance its performance in these spaces.

Hallways and Dining Areas

These high-traffic areas benefit from engineered wood’s robust construction and stylish appearance. A durable lacquer or oil finish will help the surface resist scratches and scuffs from daily use.

Home Offices and Spare Rooms

For multi-purpose spaces, engineered flooring offers an attractive yet practical solution. It pairs well with modern interiors and provides a professional finish.

Avoid in High-Moisture Areas

While engineered wood is more moisture-resistant than solid wood, it’s still not ideal for bathrooms, utility rooms, or wet areas where standing water or excessive humidity is a concern. In such cases, luxury vinyl or specially treated waterproof flooring may be more appropriate.

Pre-Installation Planning & Preparation (Crucial for Success)

Proper planning and preparation are the foundations of a successful engineered wood flooring installation. Skipping or rushing through these steps can lead to costly issues down the line, such as cupping, gapping, or even complete floor failure. By carefully assessing site conditions, acclimating your flooring correctly, and ensuring the subfloor is properly prepared, you’ll lay the groundwork for a long-lasting and visually stunning finish.

Site Conditions and Environment

Before a single plank is laid, the room’s environment must be suitable for engineered wood flooring. Wood is a natural, hygroscopic material—it absorbs and releases moisture depending on its surroundings. That’s why stabilising temperature and humidity is so important.

Temperature and Humidity

The room should be kept at a consistent temperature between 18–24°C and a relative humidity (RH) level of 45–65% for at least 7 days before installation, throughout the installation process, and afterwards. Maintaining these conditions helps prevent common post-installation issues like:

• Warping – boards becoming uneven or curved

• Gapping – unsightly spaces forming between planks

• Cupping – edges rising higher than the centre of the board

Make sure heating or air-conditioning systems are running normally to reflect the room’s actual living conditions.

Wet Trades Must Be Completed

All “wet trades” such as plastering, painting, screeding, or tiling must be fully completed and completely dry before engineered wood flooring is delivered to site. Excess moisture in the air or substrate can transfer to the floor and cause long-term damage. Use moisture metres to confirm that walls and floors are fully dry before proceeding.

Acclimation of Engineered Wood Flooring

Why Acclimate?

Engineered wood flooring, though more stable than solid wood, still reacts to the environment. It expands and contracts slightly depending on the ambient moisture content. Allowing the boards to acclimate helps them adjust to the room’s specific conditions, greatly reducing the risk of dimensional movement after installation.

How to Acclimate

• Keep boards in their sealed packaging (unless otherwise instructed by the manufacturer).

• Alternatively, lay them flat in stacks with small gaps between each box to allow air circulation.

• Place them in the room where they will be installed – not in a different area or garage.

• Acclimation time: Typically 48–72 hours, although longer periods may be necessary for large areas, colder climates, or buildings with varying humidity levels.

Subfloor Preparation – The #1 Cause of Problems

The most common cause of flooring failure is poor subfloor preparation. Regardless of your chosen installation method (floating, glue-down, or nail-down), the subfloor must be clean, dry, level, and structurally sound.

Essential Checks

Cleanliness

Remove all traces of:

• Dust, dirt and debris

• Old adhesives or glue residue

• Paint splashes or plaster spots

Thoroughly sweep, vacuum and inspect the surface to ensure it is pristine before any underlay or flooring is installed.

Dryness

Moisture is the biggest enemy of wood flooring. It is absolutely essential that your subfloor is completely dry before proceeding.

Moisture Testing Methods

• Concrete or Screed Subfloors:
  Use tools such as:

  • A hygrometer hood or in-situ RH probe

  • A CM device (calcium carbide method)

  Acceptable readings:

  • <75% RH for floating installations

  • <65% RH for full glue-down installations

  • <2.5% CM for cement-based screeds

  • <0.5% CM for anhydrite screeds

• Wooden Subfloors (Plywood or Floorboards):
  Use a wood moisture meter and aim for:

  • <12–14% moisture content (MC)

  • The subfloor’s MC should be within 2–4% of the engineered wood flooring’s MC

Damp Proof Membrane (DPM)

If you’re installing over a concrete subfloor or in a moisture-prone area:

• Use a liquid-applied DPM or

• Lay a minimum 0.25mm (1000 gauge) polyethylene sheeting as a physical barrier

The DPM should be continuous, sealed at overlaps, and run slightly up the walls to create a sealed moisture barrier.

Flatness and Levelness

Tolerance Limits

Your subfloor should be no more than 2–3mm out of level over a 2-metre span. Anything beyond this can cause movement, creaking, and joint failure.

How to Address Unevenness

• Concrete Subfloors:
  Use a self-levelling compound to smooth out dips or high spots. Follow the manufacturer’s drying times carefully before proceeding.

• Wooden Subfloors:

  • Secure any loose or squeaky boards with screws

  • Replace damaged or rotten boards

  • Sand down high areas

  • Overlay with minimum 6mm plywood or OSB for a flat, consistent surface

Soundness

The subfloor must be solid and free from movement. A subfloor that flexes, creaks or shifts can lead to structural issues and wear on the joints of your flooring.

Installation Methods Explained

Engineered wood flooring can be installed using a variety of methods, each with its own tools, adhesives, and subfloor requirements. Whether you’re opting for a floating, glue-down, or nail-down installation, the success of your project hinges on following essential principles that apply across all methods. Get these right, and you’ll enjoy a professional-looking, long-lasting floor.

General Principles for All Methods

Regardless of how you plan to fit your engineered wood flooring, the following practices are critical to achieving a flawless, high-performance result.

Expansion Gaps – Allowing the Floor to Breathe

Wood is a natural material that expands and contracts in response to changes in humidity and temperature. Even engineered wood—designed for added stability—is not immune to this movement. That’s why it’s vital to leave a 10–12mm expansion gap around the entire perimeter of the room, as well as around any fixed obstacles such as:

• Walls

• Door frames and architraves

• Radiator pipes

• Kitchen islands and units

• Fireplaces and hearths

These gaps prevent the floor from buckling or lifting as it expands. Don’t forget: if the floor spans across multiple rooms or particularly large areas (over 8–10 metres), you may need to include expansion joints or transitions to allow for additional movement.

Expansion gaps can be neatly concealed using scotia beading, skirting boards, or pipe roses once the floor is fully installed.

Planning Your Layout

A well-thought-out layout doesn’t just enhance the visual appeal of the floor—it also contributes to its long-term stability. Take the time to carefully plan the direction and positioning of the planks before installing your first board.

Direction of Planks

For the most pleasing appearance and natural flow:

• Lay the boards parallel to the longest wall in the room, or

• Lay them in the direction of the main source of natural light (usually towards a large window or glass door)

This helps accentuate the length of the room and reduces the appearance of joints.

Staggering End Joints

To avoid weak spots and repetitive patterns, end joints between boards should be staggered with a minimum offset of 300–500mm. This creates a random, more natural look and ensures:

• Better structural stability

• Reduced risk of joint failure

• A more aesthetically pleasing, professional finish

Avoid repeating patterns such as:

• “H” joints (where joints line up every other row)

• Regular brick-style offsets, which can look artificial and repetitive

Aim for a varied joint layout throughout.

First and Last Rows

Measure the room and calculate how many rows will be required. Ensure that neither the first nor the last row is narrower than 50mm. If necessary, trim the first row to achieve a balanced width for the final plank. This avoids awkward, weak slivers at the edges and provides a cleaner finish.

Mixing Planks – Achieving a Natural Look

Engineered wood is a natural product, and no two boards are exactly alike. To achieve a balanced and harmonious blend of grain, tone, and character, it’s best to work from 2–3 packs of flooring at the same time.

Mixing boards from different boxes ensures:

• A more even distribution of natural colour variations

• A more attractive, authentic finish that mimics traditional wood floors

• Avoidance of “patches” of dark or light boards clustered together

Lay out a few rows in advance (dry laying) to visualise the effect before committing to placement.

Inspecting Boards Before Installation

Before fixing any planks in place, inspect each board carefully. Look for:

• Surface damage or scratches

• Splits or cracks

• Manufacturing defects

• Damage from transport or handling

Do not install boards that are obviously defective. Most manufacturers will not accept claims on flooring that has already been installed. Set aside any boards you’re unsure about and contact your supplier if needed. A few extras are usually included in your order to account for this.

Method 1: Floating Installation (Most Popular DIY Method)

The floating installation method is by far the most popular choice for DIYers and home renovators due to its ease of installation and minimal reliance on adhesives or specialised tools. In this method, engineered wood planks are secured to each other, either via a click-lock mechanism or traditional tongue-and-groove (T&G) joints, and the entire floor forms a single, cohesive structure that “floats” freely above the subfloor.

There is no direct attachment to the subfloor itself, which makes this method both versatile and forgiving—ideal for those with basic carpentry skills.

Suitable For

• Most engineered wood flooring with click-lock or tongue-and-groove profiles

• Concrete, plywood, chipboard, vinyl, or existing wood floors (provided they are level and sound)

• Domestic settings including living rooms, bedrooms, dining rooms, and home offices

Note: Always follow the manufacturer’s installation instructions, as not all engineered flooring types are approved for floating installation.

Underlayment: What It Is and Why You Need It

A crucial component of any floating floor installation is the underlayment. This layer sits between your subfloor and the flooring planks, and its role is both functional and protective.

Purpose of Underlayment

• Provides cushioning for underfoot comfort

• Acts as a sound insulator, reducing footfall noise

• Adds thermal insulation

• Helps smooth out minor subfloor imperfections

• Offers moisture protection, particularly important when installing over concrete

Types of Underlay

• Foam – Lightweight and economical

• Felt – More durable, with better sound absorption

• Cork – Eco-friendly, naturally mould- and mildew-resistant

• Rubber – Premium choice, great for sound and thermal insulation

Some underlays also come with an integrated Damp Proof Membrane (DPM), making them ideal for installations over concrete subfloors or areas prone to moisture.

Installation Tips

• Lay the underlay flat and wall-to-wall, ensuring no wrinkles or bunching

• Tape all seams with appropriate underlay tape to hold them in place

• If using underlay with a DPM, allow it to run slightly up the wall around the perimeter to create a moisture barrier

Step-by-Step Guide to Floating Installation

Follow these steps for a smooth, professional-looking floating floor:

1. Lay the Underlay

   • Start with a clean, dry subfloor.

   • Install the underlay across the room, ensuring seams are taped and the DPM (if present) runs slightly up the walls.

2. Place Expansion Spacers

   • Insert 10–12mm spacers between the wall and the first row of planks. These will maintain the required expansion gap.

3. Start the First Row

   • Begin in a corner of the room, with the groove side of the plank facing the wall.

   • Click or slot each board into the next, using a tapping block and rubber mallet to ensure a snug fit without damaging the edges.

4. Cut End Planks to Size

   • Measure and trim the final board in each row to allow for the expansion gap.

   • Use a mitre saw or jigsaw for clean, accurate cuts.

5. Stagger the Joints

   • Begin the second row with the offcut from the previous row (minimum 300mm long) to create a staggered pattern.

   • This enhances stability and gives the floor a more natural appearance.

6. Join the Second Row

   • Angle the long edge of the plank into the groove of the first-row board and lower it down until it clicks into place.

   • Tap gently along the short edge to lock it firmly.

7. Continue Row by Row

   • Repeat the process across the room, maintaining the expansion gaps and checking for straight lines and tight joints as you go.

8. Handle Obstacles

   • Carefully mark and cut planks to fit around pipes, door frames, or fixed features.

   • Leave adequate expansion space and use pipe covers or flexible sealant to finish the look neatly.

9. Install the Last Row

   • Often the final row will need to be ripped lengthwise to fit.

   • Use a table saw for long, accurate cuts and a pull bar to fit the final planks securely into place.

Important Considerations for Floating Floors

While floating floors offer simplicity and flexibility, they come with certain caveats:

✅ Pros:

• Fast, glue-free installation

• Easy to replace or remove planks in future

• Suitable for most subfloors with minimal preparation

⚠️ Cons:

• May feel slightly hollow or “springy” underfoot, especially with thinner underlay

• Not suitable under heavy fixed furniture like kitchen islands, built-in wardrobes, or cast-iron baths

  • Heavy loads can pin the floor in place, restricting its ability to move naturally and potentially causing peaking, buckling, or joint failure

  • Many manufacturers will void warranties if floating floors are installed beneath fixed, heavy objects

For such installations, a glue-down method is often the better long-term solution.

Method 2: Glue-Down Installation

The glue-down method is a robust and long-lasting way to install engineered wood flooring, particularly suited for environments where stability and durability are key. In this method, the flooring planks are bonded directly to the subfloor using a flexible, professional-grade wood adhesive, creating a strong, stable, and acoustically solid surface.

Although it requires more time, precision, and clean-up than a floating installation, it delivers a more solid feel underfoot and allows for larger floor spans without expansion profiles—making it ideal for open-plan spaces and areas with heavy furniture or fitted kitchens.

Suitable For

• Engineered wood flooring with tongue-and-groove (T&G) or certain click-lock systems (always confirm with the manufacturer)

• Concrete or screed subfloors

• Wooden subfloors that are clean, dry, flat, and stable

• Rooms with heavy, fixed furniture (e.g., kitchen islands) where a floating floor could be compromised

Adhesive Type

Use a flexible, high-performance wood flooring adhesive, such as an MS Polymer-based adhesive. These are specifically designed for timber products and accommodate the natural expansion and contraction of engineered wood without becoming brittle over time.

Important:

• Always follow the adhesive manufacturer’s guidelines for spread rate, open time, and application method

• Check compatibility with both the flooring product and the subfloor type

• Avoid standard PVA or water-based glues unless specifically approved

Step-by-Step Guide to Glue-Down Installation

1. Subfloor Preparation

This method requires a perfectly prepared subfloor. Refer back to your earlier preparation checklist to ensure:

• The surface is clean, dry, and flat (no more than 2–3mm deviation over 2 metres)

• Moisture levels are within the required limits

• A Damp Proof Membrane (liquid DPM or sheeting) is in place if needed

2. Plan Your Layout

Dry lay the first few rows to check layout and direction. Make sure expansion gaps (10–12mm) are maintained around the perimeter and any fixed structures.

3. Apply the Adhesive

• Using a notched trowel, spread the adhesive evenly over a small section of the subfloor, starting from one corner.

• Only cover an area that can be laid within the adhesive’s open time (usually around 15–30 minutes depending on product and conditions).

• Do not spread glue over the entire floor at once—this risks premature curing and bonding failure.

4. Lay the Planks

• Place each plank into the wet adhesive and press it firmly down.

• Use a gentle sliding or twisting motion to ensure full contact with the adhesive bed.

• Tap planks together (if T&G or click system) using a tapping block and rubber mallet.

• Continue staggering joints (300–500mm minimum offset) to maintain visual appeal and structural integrity.

5. Maintain Expansion Gaps

• Continue to use spacers around the perimeter and any obstacles to maintain the recommended expansion gap.

• Do not glue planks together unless instructed by the manufacturer—most T&G installations do not require glue in the joints if the floor is fully bonded.

6. Clean Excess Adhesive Immediately

• Wipe away any glue residue from the surface of the planks before it sets.

• Use manufacturer-recommended adhesive wipes or cleaners to avoid damaging the finish.

7. Roll the Floor (If Advised)

• Some adhesive manufacturers recommend using a floor roller (approx. 45–70kg) after installation to ensure even contact and eliminate air pockets.

• Roll the floor in multiple directions if required.

Considerations for Glue-Down Installation

✅ Advantages

• Solid, stable feel underfoot – less movement, no hollow sound

• No need for underlay

• Ideal for large, open-plan spaces – allows wider spans without transition strips

• Better for fixed furniture – kitchen islands and other heavy items won’t restrict floor movement

• Improved acoustics – reduced footfall noise, less echo

⚠️ Disadvantages

• More time-consuming and labour-intensive

• Can be messy – adhesive must be handled carefully to avoid damaging the floor surface

• Difficult to remove – glued floors are harder to lift and replace

• Requires perfect subfloor prep – moisture and levelness must be spot on

Method 3: Nail-Down Installation (Less Common for Engineered Flooring)

The nail-down installation method is a more traditional technique, commonly associated with solid wood flooring, but still used with certain types of thicker engineered wood planks. In this method, boards are secured directly to a wooden subfloor using a flooring nailer or stapler, which drives nails or staples at an angle through the tongue of each plank – a technique known as secret nailing or blind nailing.

While it delivers a highly secure and solid floor, this approach is less common with engineered wood and is generally best suited to experienced installers or trade professionals.

Suitable For

• Engineered wood flooring that is specifically rated for nail-down installation

  • Typically thicker boards (e.g., 18–21mm), with robust tongue-and-groove profiles

• Wooden subfloors only, including:

  • Structural plywood

  • OSB (Oriented Strand Board)

  • Existing, sound floorboards

• Not suitable for installation over concrete or screed

Always check manufacturer guidelines before nailing engineered flooring—many thinner or click-lock boards are not designed to be nailed and may split or become unstable if fixed this way.

Required Tools

To carry out a nail-down installation, you’ll need the following specialised tools:

• Flooring nailer or stapler (pneumatic or manual)

• Compressor (for pneumatic tools)

• Flooring nails or staples – selected to match the board thickness and subfloor material

• Hammer (for starting rows or tight spaces)

• Punch and nail set (for face-nailing)

• Standard tools: tape measure, saws, spacers, spirit level, chalk line

Step-by-Step Guide to Nail-Down Installation

1. Inspect and Prepare the Wooden Subfloor

• Ensure the subfloor is dry, clean, and level (no more than 2–3mm deviation over 2 metres)

• Check that it is structurally sound and secure any squeaky or loose boards with screws

• Remove protruding nails or fixings

• Sweep and vacuum thoroughly

2. Plan Layout and Positioning

• Decide on the plank direction—typically parallel to the longest wall or main light source

• Mark a starting line using a chalk line, factoring in the 10–12mm expansion gap from the wall

3. Lay the First Row

• Place spacers along the starting wall to maintain the expansion gap

• The first row must be face-nailed, as secret nailing through the tongue isn’t possible against the wall

• Use finishing nails or screws, which will be hidden by skirting or beading

4. Begin Secret Nailing

• Starting from the second row, use a flooring nailer or stapler to drive nails or staples at a 45° angle through the tongue of each plank into the subfloor

• This blind-nailing technique conceals the fixings as subsequent rows cover the fasteners

• Ensure consistent spacing (typically every 150–200mm) and place nails at least 50mm from board ends to prevent splitting

5. Continue Across the Room

• Continue secret-nailing each board into place, staggering joints by at least 300–500mm

• Keep checking alignment and expansion gaps as you work across the room

6. Fit the Final Row

• As with other methods, the final row may need to be ripped lengthwise to fit

• If the flooring nailer doesn’t fit into the final row’s tight space, use a manual hammer and finishing nails, then punch the heads below the surface

• Cover expansion gaps with skirting, beading, or scotia mouldings

Considerations for Nail-Down Installation

✅ Advantages

• Extremely secure – creates a firm, long-lasting bond to the subfloor

• No adhesive required

• Excellent underfoot feel – minimal movement or bounce

• Ideal for multi-room continuous installations, as it allows wide spans without transition strips

⚠️ Disadvantages

• More complex – requires specialist tools and a good level of carpentry skill

• Not DIY-friendly, especially for beginners

• Only suitable for wooden subfloors – cannot be used over concrete or screed

• Not recommended for thinner engineered planks – may cause splitting or structural issues

• Harder to remove or replace individual boards compared to floating methods

Installation Methods Compared

Choosing the right installation method for your engineered wood flooring depends on your subfloor, room conditions, and skill level. Each method has its own advantages and considerations—what works perfectly for one project may not suit another.

Here’s a side-by-side comparison of the three most common installation methods to help you decide which is best for your space:

Comparison Table: Engineered Wood Flooring Installation Methods

Handling Obstacles and Tricky Areas

Even in the most straightforward rooms, flooring installations often involve working around fixed features like door frames, radiator pipes, and irregular architectural details. With the right techniques and a little patience, you can achieve a professional, seamless finish that doesn’t compromise the floor’s structural integrity or expansion requirements.

Door Frames and Architraves

Undercutting for a Seamless Finish

Instead of trying to cut the floorboard to match the exact contour of a door frame or architrave, it’s far neater—and structurally sounder—to undercut the woodwork and allow the floorboard to slide underneath.

How to do it:

1. Take an offcut of your engineered flooring and place it flat on the subfloor up against the architrave or door casing.

2. Lay a fine-toothed hand saw or oscillating multi-tool flat on the offcut and gently saw through the architrave. This will leave just enough clearance for the board (plus underlay, if used) to slide underneath.

3. Clean away any debris and test the fit with a full-length board before proceeding.

4. Always maintain the 10–12mm expansion gap, even under the frame—do not jam the board in tightly.

This technique creates a clean, integrated look and allows the wood to move naturally with changes in humidity.

Radiator Pipes

Cutting Around Pipes with Precision

Radiator pipes are a common challenge, especially in older properties. Engineered wood can still be installed cleanly around them with careful measuring and cutting.

Steps:

1. Lay the plank in position without fixing it.

2. Measure and mark the exact centre point of the pipe on the plank.

3. Use a drill with a sharp wood bit to create a hole 2–3mm wider than the pipe diameter—this allows room for expansion.

4. Next, make a straight cut from the edge of the plank to the drilled hole, creating a small wedge or segment.

5. Install the plank in place around the pipe.

6. Glue the removed wedge back into position behind the pipe using wood glue. For a neater finish, cover the gap with a pipe rose (pipe collar).

This approach ensures the flooring can expand and contract as needed, without leaving unsightly gaps.

Curved Walls and Irregular Shapes

Using Templates for Accuracy

Curved or unusually shaped areas—such as bay windows, rounded alcoves, or decorative architectural features—require more care and creativity.

Best practice:

1. Use cardboard or thick paper to create a template. Press it against the curved wall or feature, and trace the outline.

2. Place the template onto the plank and carefully trace the shape onto the wood.

3. Cut the board using a jigsaw with a fine blade, taking care to follow the line smoothly.

4. Dry-fit the piece first, adjusting as needed before final installation.

5. Remember to maintain the correct expansion gap even around curves.

This method avoids awkward, jagged cuts and helps achieve a clean, tailored finish in challenging spaces.

Fireplaces and Hearths

Preserving Expansion Around Fixed Features

Where a floor meets a fireplace hearth, it’s essential not to butt the flooring tightly against the stone or brickwork.

Key points:

• Leave a consistent 10–12mm expansion gap around all edges of the hearth or fireplace surround.

• This gap can be covered neatly using flexible sealant, scotia trim, or a threshold bar, depending on the look you want and the materials used.

• Never glue the planks directly to a hearth or bridge the expansion gap with beading or silicone.

Proper spacing allows the flooring to shift slightly without lifting, warping, or cracking over time.

Finishing Touches

Once your engineered wood flooring is fully installed, the job isn’t quite finished—the final details matter just as much as the installation itself. These finishing touches not only enhance the visual appeal of the floor but also ensure it performs correctly over time. Taking care at this stage helps preserve expansion allowances, improve transitions between rooms, and give your flooring a clean, refined finish.

Removing Spacers

After the last plank is fitted and—if using adhesive—the glue has had time to fully cure (as per the manufacturer’s instructions), it’s time to remove all the expansion gap spacers placed around the perimeter of the room and obstacles.

Removing these spacers:

• Releases the floor, allowing it to expand and contract as needed

• Prepares the space for installing skirting boards or beading to conceal the gaps

Never leave spacers in place, as this can prevent movement and lead to problems such as buckling or peaking.

Installing Skirting Boards or Baseboards

Skirting boards serve a dual purpose: they conceal the expansion gap around the room’s perimeter and protect the base of the walls from knocks and scuffs.

Best practices:

• Nail or screw skirting boards into the wall, never into the flooring itself

• Fixing to the floor will restrict natural movement, potentially causing the boards to warp or lift

• If you’re replacing skirting, consider a style that complements the new flooring for a cohesive finish

Tip: Use flexible decorator’s caulk along the top edge of the skirting for a smooth, professional seal against the wall.

Installing Beading or Scotia Trim

If you prefer not to remove existing skirting boards, beading (also called scotia trim) offers a practical and attractive alternative.

• Installed directly in front of the expansion gap

• Fixed to the skirting, not the floor

• Available in wood, MDF, or PVC, and can be matched to your floor or painted for contrast

Beading is particularly useful in renovation projects where removing and replacing skirting would be too disruptive.

Fitting Transition Strips and Door Bars

Where your new engineered floor meets other flooring types or thresholds (e.g., at doorways), transition strips ensure a safe, smooth and visually consistent join.

Why They Matter:

• Create seamless transitions between rooms with different flooring

• Cover expansion gaps

• Reduce trip hazards

• Allow movement between independently expanding surfaces

• Break up large floor spans (especially for floating floors over 7 metres in length, where an expansion joint is often required)

Common Types:

• T-Moulding: For transitions between two floors of equal height

• Reducer Strip: For bridging different heights (e.g. engineered wood to tile or vinyl)

• Threshold Bar: Used in doorways to bridge gaps between different flooring types or finishes

All transition profiles should be securely fixed to the subfloor, not to the floating flooring, to preserve movement allowance.

Cleaning Up

With the floor fitted and all trims in place, finish your installation with a thorough clean-up:

• Remove all offcuts, dust, and debris

• Use a soft brush or vacuum with a hardwood-safe attachment to clear the floor surface

• Wipe down the floor with a damp (not wet) microfiber cloth to remove residue or fingerprints

• Avoid using harsh chemicals or excessive water

Your new floor is now ready to enjoy—clean, stylish, and professionally finished.

Common Mistakes and Troubleshooting

Even with high-quality engineered wood and good intentions, mistakes during installation can lead to frustrating—and often costly—problems. Understanding common pitfalls and how to avoid or resolve them is essential for achieving a professional finish and long-term floor performance.

Poor Subfloor Preparation

One of the leading causes of flooring failure is inadequate subfloor preparation. If the surface is uneven, contaminated, or damp, the results can include:

• Squeaking or creaking underfoot

• Humps or dips that affect board alignment

• Gaps between planks

• Buckling or lifting due to trapped moisture

Solution: Always ensure the subfloor is clean, dry, flat, and structurally sound before installation. Use self-levelling compounds, secure loose boards, and test moisture levels thoroughly.

Insufficient Acclimation

Engineered wood is still a natural product and needs time to adjust to its environment. Failing to acclimate flooring properly can lead to:

• Gapping as boards contract after installation

• Warping or cupping as boards expand unevenly

• Buckling, particularly in humid or variable conditions

Solution: Acclimate boards in the installation room for 48–72 hours, or longer in large areas or high-humidity settings. Always follow the manufacturer’s acclimation guidance.

Inadequate Expansion Gaps

Expansion gaps are critical to allow for the natural movement of the floor. Too little space around the edges can cause:

• Peaking – when boards push upward at the joints

• Buckling – floorboards lifting or becoming distorted

• Planks pulling apart under stress

Solution: Maintain a consistent 10–12mm gap around the entire perimeter and around fixed objects. Never fix skirting, beading, or heavy furniture directly to the floor surface.

Incorrect Installation Method or Adhesive

Using the wrong method or adhesive type for your flooring can result in:

• Loose or unstable planks

• Joint failure or separation

• Voided manufacturer warranties

Solution: Ensure you’re using the correct installation method (floating, glue-down, or nail-down) based on the product specification. Use only flexible, wood-specific adhesives for glue-down installs.

Misaligned or Unstaggered Joints

Failing to stagger joints or align planks correctly weakens the structure and creates a disjointed, unprofessional look.

Common signs:

• “H” joints – where end joints align in every other row

• Repetitive patterns that draw the eye

• Visually awkward or structurally weak joint placements

Solution: Always stagger joints by 300–500mm and aim for a randomised, natural appearance. Take time to dry-lay rows before committing.

Cutting Errors

Rushed or inaccurate cuts can lead to:

• Wasted material

• Visible gaps or poor fitting

• Boards that are too short to provide proper support

Solution: Measure twice, cut once. Use the correct tools for the type of cut (e.g. jigsaw for curves, mitre saw for ends) and always factor in expansion spacing.

Heavy Objects on Floating Floors

Placing heavy, fixed furniture (e.g. kitchen islands, built-in wardrobes) directly on a floating floor can:

• Prevent natural expansion and contraction

• Cause peaking, buckling, or joint failure

• Invalidate the product warranty

Solution: In areas with heavy furniture or permanent fixtures, consider using a glue-down installation method for maximum stability.

Addressing Squeaks

Squeaks are typically caused by movement between boards or between the floor and subfloor.

Troubleshooting tips:

• Identify the source by walking the floor and listening carefully

• Check for loose boards or insufficient fixings

• For wooden subfloors, secure with screws through the subfloor to the joists

• In floating floors, ensure underlay is properly installed and spacers were removed

Gaps Appearing Between Boards

Gaps may develop due to:

• Poor acclimation before installation

• Moisture loss (e.g. heated environments causing shrinkage)

• Inadequate tapping during installation

Solution: Ensure proper acclimation and use a tapping block during installation to close joints tightly. Gaps may close naturally in seasonal changes, but severe gaps may require boards to be reinstalled.

Cupping and Crowning

These are moisture-related distortions:

• Cupping: Edges of the plank rise higher than the centre

• Crowning: Centre of the plank rises above the edges

Common causes:

• Excessive moisture from below or above

• No or inadequate Damp Proof Membrane (DPM)

• Wet cleaning methods or leaks

Solution: Identify and resolve the moisture source. If the floor dries out naturally, minor cupping may correct itself. Severe issues may require board replacement and improved moisture protection.

Post-Installation Care & Maintenance

Once your engineered wood flooring is installed, proper care and environmental management are essential to preserve its appearance, durability, and performance over time. Following a few simple maintenance practices will help keep your floor looking beautiful for years to come, while also protecting your investment from avoidable damage.

Initial Curing Time

If you’ve opted for a glue-down installation, it’s important to allow the adhesive to fully cure before subjecting the floor to heavy use.

• Avoid walking on the floor for at least 12–24 hours (check the adhesive manufacturer’s recommendation).

• Do not move or place heavy furniture on the flooring until the adhesive has cured completely—this could dislodge planks or create uneven bonding.

• Floating and nail-down installations typically require less downtime, but it’s still advisable to wait until all finishing touches (e.g. skirting, beading, transitions) are in place.

Cleaning Your Engineered Wood Floor

Keeping your floor clean doesn’t require elaborate routines, but it’s crucial to use the right methods and avoid damaging materials.

Daily/Weekly Maintenance:

• Sweep regularly with a soft-bristled broom or use a vacuum with a hardwood floor attachment (avoid rotating brushes which may scratch the surface).

• Clean up dust, grit, and debris promptly to avoid surface scratches.

Spills and Spot Cleaning:

• Wipe spills immediately using a slightly damp (almost dry) microfibre cloth.

• Never allow water to pool on the surface—engineered wood is moisture-resistant, not waterproof.

What to Avoid:

• Excessive water or wet mops

• Steam cleaners (they force moisture into the wood)

• Harsh detergents or ammonia-based products

• Wax or oil-based polishes unless specifically approved for your floor finish

For best results, use manufacturer-approved hardwood floor cleaners that are pH neutral and specifically formulated for engineered flooring.

Protecting Your Floor from Wear and Damage

Engineered wood is designed to be durable, but it’s still susceptible to dents, scratches, and everyday wear without the right precautions.

Essential Protection Tips:

• Attach felt pads to the base of all furniture legs to prevent scratching.

• Always lift furniture when moving it—never drag heavy items across the floor.

• Place doormats at all external entrances to trap dirt, grit, and moisture.

• Trim pet nails regularly to reduce surface scratching.

• Avoid walking on the floor in high heels or abrasive-soled shoes that can dent or scuff the wood.

Consider using rugs or runners in high-traffic areas such as hallways and entrances to add an extra layer of protection.

Refinishing (If Applicable)

One of the benefits of engineered wood flooring is that it can be sanded and refinished, depending on the thickness of the real wood wear layer.

• Floors with a wear layer of 3mm or more can usually be sanded 1–3 times over their lifespan.

• Refinishing can remove surface scratches, refresh tired finishes, and even change the stain colour if desired.

Note: Always consult the flooring manufacturer or a professional before attempting refinishing, especially with thinner wear layers (under 3mm), as sanding may cause permanent damage.

Environmental Control

Engineered wood flooring performs best in a stable indoor environment. Sudden fluctuations in temperature or humidity can cause the boards to expand or contract, leading to gapping, cupping, or crowning.

Ideal Conditions:

• Room temperature: 18–24°C

• Relative humidity (RH): 45–65%

Tips to maintain consistency:

• Use humidifiers in winter when indoor air is dry

• Use dehumidifiers in summer or in coastal/damp areas

• Avoid prolonged direct sunlight exposure—use blinds or curtains to reduce UV fading

Keeping your indoor environment within these ranges will extend the life of your floor and help it retain its natural beauty and structure.

When to Call a Professional

While engineered wood flooring is often marketed as DIY-friendly—especially with floating click-lock systems—there are situations where bringing in a professional installer is the smartest decision. Knowing when to call in expert help can save time, reduce stress, and protect your investment, especially in more complex scenarios.

Complex Subfloor Issues

If your subfloor presents challenges such as:

• Significant unevenness that requires extensive levelling

• Moisture issues that persist even after basic DPM applications

• Structural damage or uncertainty about the subfloor’s soundness

…it’s best to consult a professional flooring installer. They have the tools and expertise to assess, correct, and prepare the subfloor to industry standards—ensuring a stable and long-lasting installation.

Unusual Room Shapes or Intricate Layouts

Rooms with:

• Curved walls

• Multiple nooks and recesses

• Steps, split levels, or complex transitions

• Built-in features such as fireplaces, alcoves, or sloping ceilings

…can make even confident DIYers think twice. Professionals can handle accurate templating, precision cutting, and tricky layouts with ease, ensuring clean, seamless results that enhance the overall aesthetic of your floor.

If You’re Unsure or Uncomfortable

Installing flooring is a precise task that requires patience, attention to detail, and confidence using tools. If you’re unsure about:

• How to acclimate or prepare the floor correctly

• Using a flooring nailer or applying adhesive

• Measuring and cutting around obstructions

…it’s often better to hire an experienced installer than to risk costly mistakes. A poorly installed floor may require sections to be re-laid—or worse, replaced entirely.

For Warranty Purposes

Some engineered wood flooring manufacturers require professional installation for the product warranty to remain valid. This is especially true for:

• Glue-down or nail-down installations

• High-end or large-format boards

• Commercial or high-traffic environments

Always check the warranty terms before proceeding. Hiring a professional not only protects your warranty—it also ensures the flooring is installed to meet the manufacturer’s specifications.
