| Tools | Application parameters |
| Airless Spray | Not applicable. |
| Brush | Not applicable. |
| Roller application | Not applicable. |
With brush or roller, multiple coats are required to reach the specified dry film thickness. Thinning is generally not recommended. To reduce dry spray at high temperature, additional thinning may be required. At low paint temperature, additional thinning may be required, which gives lower film build and slower drying. Spray parameters are indicative and can be adjusted on site. Pressure values apply to material at 20 °C. (*For other application methods, consult the company representative!).

To achieve optimum performance, avoid excessive film thickness. Depending on the end use and service area, the product may be specified at film thicknesses other than those indicated. This will alter the spreading rate, drying and curing times and recoat interval. The practical consumption factor may vary with application conditions, equipment and workmanship. Checking paint consumption against area improves film thickness control.
- If brush or roller application is used, more coats are required to achieve the specified dry film thickness.
| Surface temperature | 20°C |
| Surface Dry | 60 min |

Dry film thickness measured at 25 µm under standard conditions; see Hempel's explanatory notes. To determine the drying state, refer to the application specification COP FP1401-1 (drying test for high film thickness)
For products of the same generic chemical composition, recoat times are for reference only.
For further information, refer to Hempel's specifications.
- To achieve the stated drying times, adequate ventilation during application, drying and curing is essential.
