Material estimate
Calculator: Paint & enamel · Date: · Materia
Input data
- Surface area: 42 m²
- Subtract openings: 0 m²
- Paint type: Water-based (acrylic) paint
- Coats: 2
- Coverage: 8 m²/l
- Surface: Smooth
- Reserve: 10 %
- Can volume, l: 2.5 l
Materials to buy
| Item | Quantity | Unit | Note |
|---|---|---|---|
| Water-based (acrylic) paint, 2.5 l can | 5 | pcs | 2.5 l each = 12.5 l |
| Thinner: Water | 0.92 | l | 5–10 % |
Calculation
42 m² × 2 coats ÷ 8 m²/l = 10.5 l, + 10% reserve = 11.6 l → 5 tins of 2.5 l (12.5 l).
Check the thinner against the specific manufacturer instructions. Do not mix incompatible solvents — the paint may curdle. Work in a ventilated area: solvents are flammable.
The calculation is approximate. Verify consumption against the specific material manufacturer instructions.
