How to use it
- Pick what to cover
The walls, the ceiling or both, in feet or metres.
- Type the room
Its length, width and height, and how many doors and windows it has.
- Set the sheet
Type your sheet size or tap a usual one, and the extra for waste.
Tips
- Longer sheets
Longer sheets leave fewer joints to tape. Check they fit through the door and up the stairs.
- Over the openings
Hang sheets right over doors and windows and cut the openings out afterwards: fewer joints at the corners.
- Waste
10% extra covers the cuts in a plain room. Add more for many corners, angles or openings.
