The substrate temperature must not be below 5 °C and must be at least 3 °C above the air dew point. Temperature and relative humidity must be measured on the substrate near the work area.
Do not apply outdoors in adverse weather such as rain, fog, snow, strong wind and heavy dust;
| Mixing | This product is supplied as two containers forming one unit. Stir the base thoroughly with a power mixer, add the curing agent in the specified ratio, stir again with a power mixer, and add the recommended thinner to adjust to a suitable application viscosity. Once mixed, use within the specified pot life. |

Note: the above data are measured under well-ventilated conditions, at typical film thickness and 75% relative humidity, and are for reference only.
Actual drying times and the interval before recoating may be longer or shorter depending on film thickness, ventilation, humidity, the underlying paint, requirements for early handling and mechanical strength, and other factors.
| Preceding coat | Inorganic zinc-rich, inorganic zinc silicate, water-borne inorganic zinc-rich, water-borne zinc silicate, thermally sprayed metal |
|---|---|
| Subsequent coat | Epoxy paint, epoxy micaceous iron oxide intermediate coat, polyurethane paint |
If the substrate is heavily porous, apply several coats to fully seal the surface and avoid bubbles and pinholes when applying the next coat.
