If brush or roller is used, multiple coats are required to achieve the specified dry film thickness. If a brush or roller is used, Hemucryl Brush Agent 99810 must be used. The spray parameters are indicative and may be adjusted according to site conditions. The pressure values apply to material at 20 °C.

| Theoretical Spreading Rate | 10 m²/L | 4.2 m²/L | 6.7 m²/L |
Depending on the use and the application area, the product can be specified at film thicknesses other than those indicated. This will change the spreading rate, drying and curing time and recoating interval. Over-thickness must be strictly controlled; locally, 160 µm [6.4 mil] DFT must never be exceeded. In the case of surface irregularities, particular care is recommended to avoid over-application.
