Laying laminate flooring yourself is one of the more achievable DIY projects for a NZ homeowner — most modern laminate uses a click-lock system that doesn't require glue or nails. With the right tools, a flat subfloor, and a bit of patience, you can achieve a result that looks professionally installed. Here's a complete rundown of what you'll need before you start.
Measuring and Planning Tools
Getting your measurements right before you cut a single plank saves time, money, and frustration.
- Tape measure – A 5–8 m tape is ideal for most rooms.
- Square – A combination square or speed square helps you mark accurate 90° cut lines.
- Pencil – Mark your planks clearly before cutting.
- Chalk line – Useful for snapping a straight reference line across the room to keep your rows running true.
- Graph paper or a room-planning app – Sketch your layout first to work out how many packs you need and whether you'll end up with awkward slivers at the walls.
As a general rule, add 10% to your measured floor area to allow for cuts and waste. Check the manufacturer's instructions on your specific product, as some recommend more.
Cutting Tools
You'll need to cut planks to length and width, and sometimes at angles around door frames and other obstacles.
- Mitre saw (drop saw) – The fastest and most accurate tool for cross-cuts. A basic 210 mm or 255 mm corded mitre saw handles laminate easily.
- Jigsaw – Essential for cutting curves around pipes, toilet bases, or irregular shapes. Use a fine-tooth blade to reduce chipping.
- Circular saw – Handy for ripping planks lengthways along the final row. Use a fine-tooth blade and cut with the decorative face down to minimise tear-out.
- Laminate/flooring cutter (manual scorer) – A specialty hand tool that scores and snaps planks cleanly with no dust or noise. Great for straight cuts in smaller rooms. Available at Bunnings or Mitre 10.
- Utility knife – For trimming underlay and scoring cut lines.
Safety note: Always wear safety glasses and hearing protection when using power saws. Keep fingers well clear of blades and never remove blade guards.
Installation Tools
These are the tools that actually help you fit the planks together neatly.
- Tapping block – A purpose-made block (or a scrap piece of laminate) that you place against the plank's tongue or groove and tap with a mallet to close joints without damaging the locking profile.
- Pull bar (also called a last-row puller) – A hooked metal bar that hooks over the edge of the last plank in a row so you can tap it tight against the wall. Indispensable for the final row.
- Rubber mallet – Used with the tapping block. Don't use a steel hammer directly on the planks.
- Spacers – Small plastic wedges (usually 8–10 mm) placed around the perimeter of the room to maintain the expansion gap between the flooring and the walls. This gap is critical — laminate expands and contracts with NZ's seasonal humidity changes, and without it the floor can buckle.
- Knee pads – You'll spend a lot of time on the floor. A decent pair makes a real difference.
Subfloor Preparation Tools
A flat, clean subfloor is the foundation of a good laminate installation. Most manufacturers specify the subfloor must be flat to within 3 mm over a 1.8 m span — check your product's technical data sheet.
- Long spirit level or straightedge – To check for high and low spots.
- Floor scraper or belt sander – To knock down high spots on a timber subfloor.
- Self-levelling compound – For filling low spots on concrete. Brands like Ardex and Mapei offer products suited to NZ conditions. Follow the manufacturer's instructions carefully.
- Vacuum or broom – The subfloor must be clean and dry before you lay underlay.
Underlay and Moisture Barrier
Most laminate flooring requires a foam or combination underlay. Some products come with underlay pre-attached — check before buying extra.
- Underlay – Provides cushioning, sound absorption, and minor levelling. Choose a product appropriate for your subfloor type (timber or concrete).
- Damp-proof membrane (DPM) – If laying over a concrete slab, a plastic moisture barrier (typically 0.2 mm polyethylene) is usually required to prevent moisture wicking up and damaging the laminate. This is especially important in NZ homes, where Healthy Homes standards highlight the importance of moisture control.
- Tape – To join underlay sheets and seal DPM overlaps.
Finishing Tools
- Pry bar and hammer – For removing existing skirting boards carefully so they can be re-fixed after installation.
- Nail gun or hammer and nails – To refix skirting boards over the expansion gap.
- Caulking gun – For applying silicone or flexible sealant around wet areas if the laminate runs close to a bathroom or laundry.
- Transition strip tools – Most transition strips (T-bars, reducers, end caps) simply click or glue into a track. A drill and appropriate bit may be needed to fix the track to the subfloor.
When to Call a Professional
While laying laminate is DIY-friendly, there are situations where it's worth getting a qualified flooring installer involved:
- Significant subfloor issues – Large cracks in concrete, springy or rotten timber subfloors, or out-of-level floors that need grinding or extensive levelling are best assessed by a professional.
- Wet areas – Laminate is generally not suitable for bathrooms or areas with regular water exposure. A flooring professional can advise on appropriate products and installation.
- Large or complex areas – Rooms with lots of angles, stairs, or intricate patterns are harder to get right first time.
- Underfloor heating – Not all laminate is compatible with underfloor heating systems. Check with the manufacturer and, if in doubt, consult a professional installer.
