- Surface temperature
- Check manufacturer instructions
105 Resin requires a compatible hardener; there is no universal application minimum for the resin alone. North American minimum recommended cure temperatures depend on the selected hardener: 205 Fast 4°C; 206 Slow and 207 Special Clear 16°C; 209 Extra Slow 21°C. Choose the hardener for the job and maintain suitable curing conditions. Surfaces must be clean, dry and prepared; watch for outdoor condensation. Cure time depends on hardener, temperature and film thickness. Check the complete resin/hardener instructions before use.
Check the air, the actual surface, overnight conditions and the full drying or curing period. The current product label takes precedence.
