how to lay laminate flooring

To lay laminate flooring, you’ll prep the room and subfloor, acclimate the boards, roll out underlay, then click planks together row by row with expansion gaps left at the edges. Below is a step‑by‑step, beginner‑friendly guide in a “Quick Scoop” style.

Quick Scoop

  • Laminate is a floating floor that locks together, not glued or nailed down.
  • The three big success factors: a flat and dry subfloor, correct underlay, and proper expansion gaps.
  • Most DIYers can do a bedroom in a day or weekend with basic tools and patience.

Tools and materials

Have everything on hand before you start for a smoother install.

Essential tools

  • Tape measure, pencil, combination square.
  • Handsaw, jigsaw, or laminate cutter for planks.
  • Rubber mallet and tapping block, pull bar for tight spots.
  • Spacers (to keep gap at walls), utility knife (for underlay and fine trims).
  • Spirit level to check flatness, broom or vacuum.

Materials

  • Laminate flooring planks.
  • Suitable underlay (with built‑in damp‑proof membrane over concrete).
  • Damp‑proof membrane if your underlay doesn’t include it and the subfloor is concrete.
  • Skirting boards or beading/trim, transition strips for doorways.

Safety

  • Knee pads, dust mask, safety glasses, hearing protection as needed.

Before you start: planning and acclimation

1. Measure and plan

  • Measure room length × width to work out area, then add 10% for waste (about 15% for herringbone or complex patterns).
  • Decide plank direction: usually along the longest wall or in the direction of natural light for a better visual flow.

2. Acclimate the laminate

  • Leave unopened packs of laminate in the room for at least 24 hours before installation, flat and supported.
  • Keep room temperature stable (around normal living conditions) so boards expand or contract before you fix them in place.

A quick mini‑story:
Imagine opening the packs and laying them the same hour in a cold, damp room—when heating goes on, boards expand, joints peak, and suddenly your “new” floor looks wavy. Acclimation is what prevents that.

Subfloor prep and underlay

3. Prepare the room

  • Remove all furniture, doors if needed, and existing floor coverings (carpet, old vinyl, loose tiles).
  • Take off skirting boards or, if keeping them, plan to finish with scotia/beading around the perimeter.

4. Check moisture and flatness

  • Subfloor must be clean, dry, and level.
  • Sweep or vacuum thoroughly; remove old adhesive lumps and drive protruding nails or screws below surface.
  • Use a spirit level to find high or low spots; sand down highs and fill lows with self‑levelling compound, let dry fully.
  • On concrete, add a damp‑proof membrane or use an underlay that includes one.

5. Roll out the underlay

  • Roll out underlay in the same direction you’ll lay the flooring, fitting it up close to walls.
  • Tape seams together so it doesn’t move while you’re working; avoid overlapping unless the manufacturer specifies it.
  • With concrete, ensure the moisture barrier layer reaches slightly up the wall (about 5 cm) to protect edges; trim later.

Laying the laminate: row by row

6. Decide your starting point

  • For standard single‑plank laminate, start along the longest, straightest wall.
  • Mix planks from different packs so colour and pattern variations are distributed evenly across the room.

7. Use spacers for expansion gaps

  • Place 10–12 mm (about ¼ inch) spacers between planks and walls, radiator pipes, and other fixed objects.
  • This expansion gap lets the floor move slightly with temperature and humidity; it will be hidden by skirting or beading.

8. Lay the first row

  • Position the first plank with its tongue side toward the wall, groove facing into the room.
  • Add the next plank by angling and clicking/tapping the short end into the previous one; continue along the wall.
  • For the last plank in the row, flip it end‑to‑end next to the gap, mark the cut, cut it, then fit it in place, keeping the spacer at the wall.

9. Stagger your joints

  • Use the offcut from the end of Row 1 to start Row 2 if it’s long enough; this staggers the joints.
  • Maintain at least about 30 cm (or 6 inches minimum) between end joints in adjacent rows for strength and appearance.

10. Continue with subsequent rows

  • Angle the tongue of the new plank into the groove of the previous row, click down, then tap the short end into the previous plank in the same row.
  • Keep checking that rows remain straight and gaps are tight; use a tapping block and mallet for snug joints without damaging edges.
  • Use a pull bar for the last plank in each row or where the wall prevents using a tapping block.

Dealing with obstacles and awkward areas

11. Door frames and architraves

  • A clean way is to undercut the door frame and architrave so a plank can slide under for a neat finish.
  • Lay a piece of underlay and a board against the frame, use a saw or multi‑tool resting on the board as a height guide, then cut the frame and remove the waste.

12. Radiator pipes and similar obstacles

  • Mark the pipe position on the board, drill a hole slightly larger than the pipe, then cut a small “V” or notch to the hole.
  • Fit the plank around the pipe and glue the small offcut behind the pipe; cover with a pipe rose for a tidy look.

13. Final row

  • Measure the remaining gap to the wall, subtract the expansion gap, and cut planks lengthwise to fit.
  • Use a pull bar to snug the final row into the previous one, maintaining the expansion gap using spacers.

Finishing touches and aftercare

14. Trim and cover gaps

  • Remove all spacers once the floor is laid so the boards can move.
  • Fit skirting boards or beading to cover expansion gaps, fixing them to the wall, not to the flooring itself.
  • Add transition strips at doorways where laminate meets another floor type for a smooth threshold.

15. Clean and protect

  • Vacuum or sweep and then damp‑mop lightly if the manufacturer allows it; avoid soaking the floor.
  • Add felt pads to furniture feet and avoid dragging heavy items across the new surface to prevent scratches.

Common mistakes to avoid

  • Skipping acclimation, leading to gaps or buckling later.
  • No expansion gaps or fixing boards hard against walls, causing tenting or squeaks.
  • Laying over an uneven or damp subfloor, which can damage joints and cause soft spots.
  • Not staggering joints sufficiently, making the floor weaker and less attractive.

Mini FAQ

Do I need underlay?
Yes; underlay cushions the floor, reduces noise, and helps with moisture control, especially over concrete.

Can laminate go in kitchens?
Many products can, but you must control moisture, wipe spills quickly, and follow the specific product’s guidance.

Can I install laminate over existing tiles?
Often yes, if tiles are firmly fixed, level, and dry, and you use a suitable underlay; check your laminate’s installation instructions.
