How to Install Laminate Flooring: A Complete Step-by-Step Guide

Laminate flooring is one of the most popular choices for both professionals and DIY enthusiasts — and for good reason. It's affordable, durable, and with modern click-lock systems, you don't need glue, nails, or years of experience to get a great result. But here's the catch: the quality of your installation depends almost entirely on what you do before you lay the first board.

This guide walks you through the entire process, step by step, based on installation guidelines from leading flooring manufacturers.

What You'll Need

Before you start, gather everything so you're not running to the hardware store mid-project:

Tape measure and pencil
Spacers (8–12 mm, depending on your product)
Tapping block and rubber mallet
Pull bar (for the last row and tight spots)
Saw (jigsaw or circular saw; hand saw works in a pinch)
Underlayment (foam, cork, or felt — check your manufacturer's recommendation)
Vapour barrier (required for concrete subfloors)
Protective gloves for cutting

Step 1: Prepare the Subfloor

This is the step most people rush through — and the one that causes the most problems later. Your subfloor must be:

Level: No more than 2–3 mm deviation per metre. Use a long straightedge or spirit level to check. Sand down high spots and fill low spots with levelling compound.
Clean: Sweep and vacuum thoroughly. Even small debris under the underlayment can cause annoying creaks.
Dry: For concrete subfloors, perform a moisture test. Excess moisture will ruin your floor from below. If in doubt, use a vapour barrier sheet under the underlayment.

Remove any old flooring, carpet tack strips, or protruding nails. If you're laying over tiles, ensure no tiles are loose and joints aren't too deep.

Step 2: Acclimate Your Laminate

This isn't optional — it's essential. Laminate is a wood-based product that expands and contracts with changes in temperature and humidity. If you install it straight from a cold warehouse, it will shift after installation.

Lay the unopened packages flat in the room where they'll be installed
Wait at least 48 hours before starting
Keep the room at minimum 18°C with 40–70% relative humidity
Place packages at least 50 cm from exterior walls
Don't stack too high — allow air circulation around the boxes

This is what every major flooring manufacturer recommends. Skip it and you risk gaps appearing weeks after installation.

Step 3: Plan Your Layout

Before cutting a single board, do the maths:

Measure the room width and divide by the plank width. This tells you how many full rows you'll have.
Check the last row. If it would be narrower than 5 cm, trim the first row to balance both sides. Nothing looks worse than a sliver of laminate against the far wall.
Choose your laying direction. The general rule: lay parallel to the longest wall or in the direction of the main light source. Boards running toward a window create fewer visible joint shadows.
Decide on your pattern. Straight, 1/3 offset, 1/2 offset, or random — each has different staggering requirements and waste levels.

This is exactly where our layout planner saves you serious time. It calculates the optimal starting position, shows you every cut, and estimates material needs — before you touch a saw.

Step 4: Install the Underlayment

Roll out your underlayment across the subfloor:

Butt the seams (don't overlap foam underlayment) and tape them together
If using a separate vapour barrier, lay it first with 20 cm overlaps, taped at the seams
Some premium underlayments come with an integrated moisture barrier — check the product specs
Trim the underlayment flush with the walls

Only lay enough underlayment for the area you'll cover that session. Walking on exposed underlayment can damage it.

Step 5: Lay the First Row

The first row sets the foundation for everything else. Get this wrong and every subsequent row will be off.

Position the tongue side toward the wall (you'll cut the tongue off if your product instructions say so)
Insert spacers between the planks and the wall — 8 to 12 mm, as recommended by your manufacturer
Click the short ends of the planks together, working left to right
Cut the last plank to fit, leaving the expansion gap at that end too
If the offcut is at least 20–30 cm long, save it to start the next row

Pro tip: Don't lay the first row flush against the wall — walls are almost never straight. The spacers handle this, but always double-check with a level.

Step 6: Continue Row by Row

Now you're in a rhythm:

Start each new row with an offcut from the previous row (if it's long enough) or cut a new starter piece
Stagger the end joints by at least 20–30 cm from the row above. This prevents weak "H-joints" and looks far more natural
Angle the long side of each plank into the groove of the previous row (usually ~20–30°), then press down until it clicks flat
Use the tapping block and mallet to snug planks together — never hit the laminate directly
Check alignment every few rows. It's much easier to fix a slight drift now than to tear up half a floor later

Mix planks from different boxes to ensure natural colour variation across the floor.

Step 7: Handle the Last Row and Finishing

The final row usually needs to be cut lengthwise:

Measure the remaining gap at several points (remember — walls aren't straight)
Subtract your expansion gap (8–12 mm)
Mark and cut using a jigsaw. Position the plank decoration-side up when cutting
Use the pull bar to click the last row into place — there's no room for a tapping block here

Once all planks are down:

Remove all spacers
Install skirting boards to cover the expansion gaps. Critical: nail or glue the skirting to the wall only, never to the floor. The floor must be free to move underneath
Add transition strips at doorways and where the floor meets different flooring types

The Expansion Gap: The Rule You Must Not Break

This deserves its own section because it's the single most common cause of laminate floor failure.

Laminate flooring must have an expansion gap around every wall, pipe, door frame, and fixed object. The standard recommendation is 8–12 mm, but for larger rooms, manufacturers suggest a useful formula: 1.5 mm of gap per running metre of floor surface. A 10-metre-long room, for example, needs about 15 mm of expansion space at each end.

Without this gap, your floor has nowhere to go when it expands. The result: buckling, warping, and popping joints — sometimes weeks or months after installation, often in the middle of summer when humidity peaks.

Wrapping Up

Laminate flooring installation is genuinely achievable for anyone willing to respect the process. The boards click together easily. The tools are simple. The techniques aren't complex. What separates a professional-looking result from a frustrating one is preparation and planning.

Measure your room, acclimate your materials, level that subfloor, and plan your layout before you cut.
