Ghid Complet pentru Calculator Vopsea

Camera, usi, ferestre si straturi: suprafata, litri si galeti.

Examples

  • 4×5m room, H2.7m, 1 door 1 window: wall 48.6, net 45.2 m², 10 m²/L 2 coats → 9.0 L → 9×1L or 2×5L.
  • 3×3m, H2.5m, no openings, 1 coat 12 m²/L → 2.5 L → 3 cans 1L.

⚠ Common mistakes

  • Forgetting to subtract doors/windows — overbuys 3-4 m² per opening.
  • One coat math when you need two — most colors need two coats for opacity.
