The following sections explain pre-installation checks, tools, installation steps, subfloor-specific installation, and common problems.

Pre-Installation Checks

Before installing laminate flooring, check the following conditions. If these conditions are not met, installation may fail.

Subfloor Flatness

Check the subfloor flatness against the manufacturer's specification. Uneven subfloors can cause lipping at joints, gaps, and locking system failure.

Moisture

Check the subfloor moisture content. Concrete subfloor moisture content must be verified before installation. High moisture can cause adhesive failure, mould growth, and damage to the flooring. A moisture meter or calcium chloride test can be used.

Room Conditions

Check the room temperature and relative humidity. The installation area should be at a stable temperature, typically 18–25°C, with relative humidity typically 40–65%. Acclimate the flooring in the installation area before installation. If the room conditions are outside these ranges, adjust the HVAC system or wait for conditions to stabilise before installation.

Expansion Requirements

Check the expansion requirements for the product and the room size. Expansion gaps must be provided at the perimeter and at intermediate intervals. The required gap depends on the room size and the expected temperature variation. Follow the product installation manual.

Product Compatibility

Check that the product is compatible with the substrate and the intended use. For example, verify that the product is suitable for underfloor heating if underfloor heating is present.

Underfloor Heating

If underfloor heating is present, verify the product's underfloor heating compatibility and follow the underfloor heating manufacturer's instructions.

Note: Technical parameters such as AC3/AC4/AC5, HDF density, and locking strength are product selection considerations. For installation, the key factors are subfloor condition, moisture, room conditions, and expansion requirements. See the laminate hardwood flooring page for product selection guidance.

Tools Needed to Install Laminate Flooring

How to Install Laminate Flooring Step by Step

The following steps describe the laminate flooring installation process. For specific installation requirements, always follow the manufacturer's instructions.

Step 1: Prepare the Subfloor

Clean the subfloor thoroughly. Remove debris, oil, and grease. Level any uneven areas with self-levelling compound. Allow the compound to cure fully before installation.

Step 2: Check Moisture and Flatness

Verify subfloor moisture content and flatness against the manufacturer's specification. Address any issues before proceeding.

Step 3: Acclimate the Flooring

Acclimate the laminate flooring in the installation area before installation, with packaging opened, so the planks can adjust to the room conditions. Follow the manufacturer's acclimation instructions. Acclimation allows the product to adjust to the room temperature and humidity.

Step 4: Install Vapor Barrier When Required

If a vapour barrier is required (typically for concrete subfloors), install it with taped seams, extended up the walls. Follow the manufacturer's instructions.

Step 5: Install Underlayment

If underlayment is required, install it according to the manufacturer's instructions. Underlayment provides acoustic performance and minor subfloor tolerance.

Step 6: Plan the First Row

Plan the installation layout before starting. Determine the direction of the planks and the starting point. For the first row, cut the planks to size if needed, allowing for the expansion gap.

Step 7: Install the First Row

Start installation from the longest wall. Maintain the required expansion gap at all walls using spacers. Install the first row with the tongue facing the wall.

Step 8: Install Remaining Rows

Connect the planks using the click-lock system. Insert the plank at the required angle and engage the lock. Use a tapping block (not a mallet) to ensure full engagement. For the last plank in a row, cut it to size and use a pull bar to engage the lock. Cut around obstacles such as door frames and pipes as you work, allowing for the expansion gap.

Step 9: Install Transitions

Install transition profiles at doorways and at the junction between laminate and other flooring types.

Step 10: Check Expansion Gaps

Verify that the expansion gaps are maintained at all walls and at intermediate intervals. For large rooms, install expansion profiles at the required intervals.

Step 11: Final Inspection

Inspect the finished floor for gaps, lipping, and joint engagement. Verify that the expansion gaps are maintained. Clean the floor and remove any debris. Install baseboards or quarter-round moldings to cover the expansion gap at the perimeter.

Installation Quality Checklist

After installation, check the following:

• Expansion gaps maintained at all walls.

• Joints fully engaged (no visible gaps between planks).

• No lipping at joints.

• Transition profiles installed correctly.

• Baseboards or moldings installed.

• Floor clean and free of debris.

• No hollow or clicking sounds when walking on the floor.

How to Install Laminate Flooring Over Different Subfloors

Installation requirements vary by substrate. The following sections explain the key considerations for each substrate type.

Over Concrete

Key considerations: Moisture test, vapour barrier, flatness.

Concrete subfloors must be dry, flat, and clean. Verify moisture content before installation—typically ≤2.5% for laminate, depending on the product specification. Install a vapour barrier with taped seams, extended up the walls. Level any uneven areas with self-levelling compound and allow the compound to cure fully before installation. If the concrete is new, allow it to cure for the recommended period before installation. Verify the concrete surface is free of curing compound, oil, and grease—grinding or shot-blasting may be required.

Installation notes: Vapour barrier is required for concrete subfloors. Expansion gaps must be maintained at all walls. For large rooms, install expansion profiles at intermediate intervals.

For detailed installation over concrete, see the laminate flooring installation over concrete page.

Over Wood Subfloor

Key considerations: Structural stability, loose boards, moisture, flatness.

Wood subfloors must be sound, flat, and securely fastened. Repair or replace loose boards before installation. Verify moisture content—wood subfloor moisture content should be within the range specified by the manufacturer. Level any uneven areas with appropriate materials. If the wood subfloor is installed over a crawl space, verify that the crawl space is properly ventilated and that a vapour barrier is installed.

Installation notes: A vapour barrier may not be required over wood subfloors, depending on the manufacturer's instructions. Expansion gaps must be maintained at all walls.

For detailed installation over wood, see the laminate flooring installation over wood page.

Over Existing Tile

Key considerations: Tiles firmly bonded, grout and height, flatness, underlayment.

Laminate can be installed over existing tile if the tile is firmly bonded, flat, and clean. Loose tiles must be removed and the area levelled. Grout lines may need to be filled if they create unevenness beyond tolerance. Underlayment may be required to provide a smooth surface. Verify that the tile surface is free of wax, sealant, and other contaminants.

Installation notes: A vapour barrier may be required depending on the substrate beneath the tile. Expansion gaps must be maintained at all walls. The additional height of the laminate over the tile must be considered at doorways and transitions.

For detailed installation over tile, see the laminate flooring installation over tile page.

Common Laminate Flooring Installation Problems

The following problems are commonly observed in laminate flooring installations. Each entry explains the cause and the solution.

Problem 1: Planks Separate

Cause: The locking system is not fully engaged, the subfloor is uneven, or the installation angle was incorrect.

Solution: Check the subfloor flatness and address any unevenness. Use a tapping block and pull bar to ensure full engagement of the locking system. Follow the locking-system instructions for the correct installation angle. If the planks have already separated, disassemble the affected area and reinstall with correct technique.

Problem 2: Floor Buckles

Cause: Insufficient expansion gap, moisture, or a large uninterrupted floor area.

Solution: Increase expansion gaps and install expansion profiles at intermediate intervals. Address the moisture source. For large rooms, ensure that expansion profiles are installed at the required intervals.

Problem 3: Clicking or Hollow Sound

Cause: Uneven subfloor, inadequate underlayment, or debris beneath planks.

Solution: Address subfloor flatness. Verify underlayment installation. Clean the subfloor before installation to remove debris that could cause hollow spots.

Problem 4: Edge Swelling

Cause: Moisture, unsuitable substrate, or water exposure.

Solution: Address the moisture source. Verify substrate suitability for laminate flooring. Clean up spills promptly and avoid excessive water during cleaning.

Problem 5: Damaged Locking Edges

Cause: Direct hammering, wrong installation angle, or forcing boards together.

Solution: Replace damaged planks. Use a tapping block (not a mallet) and follow the correct installation angle. Do not force boards together—if a board does not engage easily, check the alignment and the locking profile.
