What to know about this material
- Boxes are sold whole — always round up, never down.
- Buy all boxes from one batch so the colour and grain match.
- Keep one spare pack sealed for repairs; discontinued ranges are hard to match later.
Frequently asked
- How much flooring waste should I add?
- 10% for a straight lay in a simple room, 15% for diagonal or busy layouts, and up to 20% for herringbone or rooms with lots of alcoves.
- Do I include closets and doorways?
- Yes if you are flooring them. Add the closet footprint and about 0.2 m² per doorway threshold.
- How do I work out boxes?
- Divide the total area including waste by the coverage printed on the box, then round up to the next whole box.
- Do I need underlay?
- Most floating floors do. Buy roughly the room area plus 5% for overlaps.
