Consumption
| Layer | Product | Consumption |
| Primer | Sikafloor®-150 Sikafloor®-150 Plus Sikafloor®-151 Quartz sand (0.3–0.8 mm) or Sika® Aggregate-501 | 1–2 × 0.3–0.5 kg/m² (~0.2-0.4L/m2) per layer 1.0 kg/m2 broadcast |
| Waterproofing membrane | Sikafloor®-376 | 1.9–3.0 kg/m2 (~1.6-2.5L/m2) |
| Wearing layer | Sikafloor®-377 filled 1 : 0.4 with Quartz sand (0.1–0.3 mm) Sika® Aggregate-508 Broadcast to excess with Quartz sand (0.3–0.8 mm) Sika® Aggregate-501 | 1.7 kg/m2 ( ~1.25L/m2)resin + 0.85 kg/m2 (quartz sand filler) Sika® Aggregate-508 4–6 kg/m² (broadcast) Sika® Aggregate-501 |

The application rate of Sikafloor®-376 is dependant on the substrate surface roughness, Rz:
| Rz = 0.0 | 1.9 kg/m² (~1.6L/m2) |
| Rz = 0.5 | 2.5 kg/m² (~2.1L/m2) |
| Rz = 1.0 | 3.0 kg/m² (~2.5L/m2) |
Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.
