If brush or roller is used, multiple coats are required to obtain the specified dry film thickness. Do not thin the components separately — thinning after mixing is permitted. The pot life of water-borne two-component epoxy and polyurethane cannot be determined by the appearance change of the coating itself. In addition, unlike other coatings, the pot life shortens as the temperature decreases. Discard remaining paint beyond the pot life. Keep thinning to a minimum. Spray parameters are indicative and may be adjusted to site conditions. Pressure values apply to material at 20 °C. (*For other application methods, consult a company representative!).
| Specification range | Low | High | Recommended |
| Dry Film Thickness | 50 µm | 100 µm | 75 µm |
| Wet Film Thickness | 89 µm | 179 µm | 134 µm |
| Theoretical Spreading Rate | 11 m²/L | 5.6 m²/L | 7.5 m²/L |
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.
- Before switching between solvent-borne and water-borne coatings, consult Hempel regarding pump cleaning.
- If brush or roller application is used, more coats are required to achieve the specified dry 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.
- Avoid exposing touch-up areas, full coats and intercoat intervals to high humidity during application.
