Required
12 m²
Incl. waste
13.8 m²
Leftover
13 m²
1 roll × 25 m²
How this is calculated
12.00 m² × 1.15 = 13.80 m²

Screed

Sand-cement dry mix (bagged)
Required
1,200 kg
Incl. waste
1,260 kg (+5%)
Leftover
75 kg
51 bags × 25 kg
How this is calculated
m = 12.00 m² × 50.0 mm × 2.00 kg/m²/mm × (1 + 5%) = 1260.0 kg → ⌈1260.0 / 25⌉ = 51 bags

Required
33.1 pcs (11.92 m²)
Incl. waste
37 pcs (+10%)
Leftover
6.9 pcs
10 boxes × 4 pcs
How this is calculated
N_net = 12.00 m² × 10⁶ / ((600 + 2) × (600 + 2)) = 33.11; N = ⌈33.11 × (1 + 10%)⌉ = 37; boxes = ⌈37 / 4⌉

Fixing

Tile adhesive (10 mm notch)
Required
48 kg
Incl. waste
52.8 kg (+10%)
Leftover
27 kg
3 bags × 25 kg
How this is calculated
notch 10 mm: c = 4.0 = 4.00 kg/m²; m = 12.00 × 4.00 × (1 + 10%) = 52.8 kg → ⌈52.8 / 25⌉ = 3 bags
Grout (cement)
Required
1.3 kg
Incl. waste
1.5 kg (+15%)
Leftover
0.7 kg
1 pack × 2 kg
How this is calculated
G = (600 + 600) / (600 × 600) × 2 × 10 × 1.6 = 0.107 kg/m²; 12.00 m² × 0.107 × (1 + 15%) = 1.47 kg

Incl. waste
14.52 m (+10%)
Leftover
3.6 m
7 boards × 2.4 m
How this is calculated
P = 14.00 m; P_sk = 13.20 m; 13.20 × (1 + 10%) = 14.52 m → ⌈14.52 / 2.4⌉ = 7 boards
