FAQ
Why do I need multiple coats?
Covering dark colors or significant color changes usually requires 2+ coats. Recommended: 1 coat primer + 2 coats top coat.
How much area can 1 liter cover?
Typically 8-12 m² per liter per coat. Actual coverage depends on wall texture, paint viscosity, and application method.
Should I add extra margin?
Add 10-15% extra for touch-ups and future repairs. Irregular walls or many corners may need more.
