How to lay a floating floor

Before laying laminate flooring, an underlay should be fitted to your floor. If you are unsure which underlay to use, chat to the staff at your local Mitre 10. On a concrete slab, it will be covered with a damp-proof underlay.

Project Checklist


  • Laminate floor boards
  • Foam underlay
  • Trim
  • Expansion blocks
  • Utility knife
  • Knee pads

Step 1: Lay the Underlay

Step 1: Lay the Underlay

Lay the underlay over the floor area and place the lengths side by side. Trim it to fit with a utility knife. Tape the joins and make sure that they don’t overlay- tape is usually provided with underlay, if not use 48mm PVC tape.

Step 2: Laying Boards

Step 2: Laying Boards

Begin laying the boards in a left hand corner with the short tongue against the wall. Place the expansion block against the end of the board and at intervals along the wall. If you have a section left over from the first row, you can use this to start the second row. You'll need to stagger the joints between the boards randomly to get a good result, so make sure the planks are about 400mm on either side of the join in the previous row.

Step 3: Remove Expansion Blocks

Step 4: Look after your new floor

Now to look after your new laminated floor, wipe everyday marks away pretty quick and easy with just a damp cloth. But stay away from any abrasives.

So there it is… a brand new floor that you can do yourself and looks fantastic!
