Häufig gestellte Fragen

Typical bag coverage?
A 1-kg bag typically covers 3–5 m² depending on brand and application technique. Check the manufacturer datasheet.
Why a waste allowance?
Liquid wallpaper has drying and mixing losses. A 10% allowance is the usual default for experienced applicators; DIYers should use 15%.
Do I subtract windows and doors?
Yes — compute net wall area first (total wall − openings) before entering it here.
