Laminate Flooring Installation Guide: Preparation and How It Is Laid

Most laminate flooring uses a click system to form a floating floor. The boards join to each other over a prepared subfloor rather than being fixed down, which means flatness, moisture control and expansion space are essential. This guide explains the normal preparation and laying sequence.

Read the product instructions first

Confirm the board dimensions, joint profile, suitable rooms, moisture rating and underfloor-heating limits. Packs from different manufacturers can require different angles, tapping methods and row staggering. Check every pack for the correct decor and batch before opening.

Condition the laminate

Store unopened packs flat in the room for the period and conditions specified by the manufacturer. Keep them away from recently plastered, unheated or damp spaces. Stable room conditions matter more than following a generic acclimatisation rule.

Prepare the subfloor

  • Remove debris, high spots, loose fixings and material that could make the boards rock.
  • Confirm the surface meets the product’s flatness tolerance over the stated measuring distance.
  • Assess concrete and screeds for moisture, using the required vapour-control layer where specified.
  • Secure timber boards and correct movement or protruding fixings.
  • Do not rely on soft underlay to hide an uneven base; it can stress click joints.
  • Check finished floor height at doors, stairs, appliances and adjoining rooms.

Choose the correct underlay

Underlay should be compatible with the laminate, subfloor, click system and any underfloor heating. Some boards have an attached layer and must not receive an extra soft underlay. Where a separate vapour barrier is required, tape and turn-up details must follow the instructions.

Plan the layout

Decide the board direction and calculate the widths of the first and last rows. Adjust the start so the last row is not unnecessarily narrow. Plan doorway breaks and any movement profiles needed between rooms or across large areas. Measure fixed objects and mark a straight starting line rather than assuming walls are square.

How laminate is laid

  1. Place the underlay. Lay, join and seal it using the specified method without unnecessary overlaps or soft ridges.
  2. Start the first row. Orient the boards as directed and use spacers to maintain the required expansion gap from the wall.
  3. Join the boards. Engage the end and long joints using the product-specific angle or tapping procedure. Use a tapping block only where permitted; never strike the decorative edge directly.
  4. Stagger the rows. Keep end joints separated by at least the stated minimum and avoid a repetitive stair-step appearance.
  5. Cut around details. Undercut door linings where appropriate, leaving concealed movement space. Maintain clearance around pipes and fixed objects.
  6. Lay the final row. Measure at several points, allowing for the expansion gap, and use the correct pulling tool to close joints without damaging the edge.
  7. Fit trims. Remove spacers, then fix skirting or scotia to the wall rather than through the floating floor. Use transition profiles that do not restrict movement.

Underfloor heating

The heating system and laminate must be compatible. Follow the commissioning procedure, maximum surface temperature and rate-of-change limits supplied by both manufacturers. Heat should be distributed evenly; thick rugs or furniture arrangements can create local temperature differences.

After laying

Check that rows are straight, joints are fully closed and movement gaps remain clear. Vacuum with a hard-floor tool and use the recommended initial clean. Lift furniture into position with clean protective pads. Do not trap the floating floor beneath fixed cabinetry or screw thresholds through it.

Common problems to avoid

  • Installing over a damp or uneven subfloor.
  • Choosing incompatible or excessively soft underlay.
  • Omitting expansion gaps at walls, pipes and door frames.
  • Forcing a click joint that is not aligned.
  • Creating short, weak end pieces or closely repeated joints.
  • Restricting movement with fixed trims or heavy built-in items.
