If brush or roller application is used, multiple coats are needed to achieve the specified dry film thickness. To reduce dry spray at high temperatures, additional thinning may be needed. At low paint temperatures, additional thinning may be needed, which will result in lower film build and slower drying. Spray parameters are indicative and can be adjusted according to site conditions. Pressure values apply to material at 20 °C. (*Consult the company representative if other application methods are needed!)

| Theoretical Spreading Rate | 16 m²/L | 7 m²/L | 10 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.
- Ideal spray performance is obtained at paint temperatures of 15–30 °C [59–86 °F]; outside this range, additional thinning may be required.
- If brush or roller application is used, more coats are required to achieve the specified dry film thickness.
