Yield ~1.4 kg of dry mix per m² and mm of thickness. Finish coat is thinner (2–3 mm), base coat 10–20 mm.

How to calculate plaster consumption

Plaster consumption is calculated from the wall area, layer thickness, and the yield of the specific mix. Most dry plaster mixes use roughly 1.4 kg per m² for each millimetre of thickness:

consumption (kg) = area (m²) × thickness (mm) × 1.4

Example: 36 m² of wall (after subtracting windows and doors), a 10 mm layer → 36 × 10 × 1.4 = 504 kg, i.e. 17 bags of 30 kg. Don't forget to subtract the area of windows and doors.

Base coat vs. finish coat

The base (rough) coat is applied 10–20 mm thick and levels the wall. The finish coat is a fine, final 2–3 mm layer for a smooth surface. For a finish coat, enter a smaller thickness – consumption will be significantly lower.

Note: consumption is approximate and varies by the specific mix and the flatness of the surface. Follow the manufacturer's specifications.
