RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES
Substrate conditions
- Previous coat (epoxy or polyurethane) must be dry and free from any contamination
- Previous coat: surface should be sufficiently roughened if necessarySubstrate temperature and application conditions
- Substrate temperature during application at -5°C (23°F) is acceptable; provided the substrate is free from ice and dry
- Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
- Relative humidity during application and curing should not exceed 85%
- Should condensation on the surface occur during, or soon after application, this could result in color and gloss change
INSTRUCTIONS FOR USE
Mixing ratio by volume: base to hardener 88:12
- The temperature of the mixed base and hardener should be above 10°C (50°F), otherwise extra thinner may be required to obtain application viscosity
- Thinner should be added after mixing the components
- Adding too much thinner results in reduced sag resistance induction time
- Pot life; 5 hours at 20°C (68°F)
